Abstract Title
PLiS Fix: AI Personalised Liverpool Scleral-Fixated IOL Calculator
Purpose
To develop and validate a calculator to improve the refractive results of scleral-fixated IOLs (Carlevale and Yamane).
Setting/Venue
University of Liverpool and Royal Liverpool Hospital
Methods
A MATLAB-based algorithm based on 118 subjects was designed to model the whole eye and predict ELP in scleral-fixated IOLs. Biometric parameters were used to generate a personalised model.
Results
The algorithm estimated the optimal fixation distance from the limbus and accounted for refractive shift based on the estimated ELP. Three representative eye models were formulated: short (AL <21 mm), normal (AL ~23 mm), and long (AL ~28 mm).
Conclusion:
PLiS Fix is a novel personalised tool for scleral-fixated IOL planning. It can potentially improve the predictability of lens position and refractive outcome, supporting safer and more consistent surgery.

Abstract Title
Carlevale sutureless scleral fixated (Soleko) IOL: Functional outcomes, haptic exposure rates and the use of anterior segment OCT to determine T-bar haptic depth
Purpose
1) To determine the visual outcomes following Soleko IOL_x000D_
2) To determine cystoid macular oedema (CMO) rates for this patient cohort_x000D_
3) To determine the rate of haptic erosion through the conjunctiva_x000D_
4) To image and determine the intrascleral Soleko T-bar haptic depth using OCT
Setting/Venue
Leeds Teaching Hospitals
Methods
This was a retrospective notes audit using Medisight and Heidelberg imaging review of patients treated with Soleko IOL between Sept 2022 to June 2024. Indications for Soleko IOL included: complicated cataract surgery without capsular support, dislocated IOL, dislocation of crystalline lens and intractable CMO related to Artisan/Yamane IOL. Soleko IOL were fixated 1.5mm behind the limbus and covered with bi-circumferential pockets measured at a depth of 350 microns with a guarded blade. Anterior segment OCT images were taken for patients at follow up review in the clinic.
Results
74 patients underwent Soleko IOL with 323 (14-911) days mean follow up duration. Mean unaided visual acuity improved 6 lines from 2/60 to 6/12. The CMO rate was high (17.6%) as expected in a cohort with high ocular co-morbidity (post-lens drop/retinal detachment), but with good resolution rates (92%) following treatment. 2.7% cases underwent prophylactic tutoplast to prevent erosion (neither case experienced full T-bar erosion through the conjunctiva and both were noted to be superficial at first postoperative visit). Seven patients underwent anterior segment OCT (mean 680 days postoperatively) showing the T-bar buried a mean 295 microns below the ocular surface.
Conclusion:
Soleko IOL offers good visual outcomes for patients with deficient capsule support. CMO rates are high due to case co-morbidity and respond to treatment. Haptic exposure concerns can be treated with tutoplast and are often evident early postoperatively. Anterior segment OCT provides an objective option for monitoring Soleko T-bar depth.

Abstract Title
Visual and Surgical Outcomes Following Oculentis IOL Explantation: Capsular Bag Preservation vs. Scleral Fixation
Purpose
To assess visual, refractive and surgical outcomes following exchange of an opacified IOL with and without preservation of the capsular bag.
Setting/Venue
Single-centre, single-surgeon retrospective case series in a private sector provider between the years 2017-2025
Methods
We reviewed the records of 179 eyes undergoing intraocular lens (IOL) exchange surgery for opacified Oculentis IOLs. Capsular bag preservation, best-corrected visual acuity (BCVA), refractive prediction error and incidence of postoperative cystoid macular oedema (CMO) were assessed.
Results
Capsular bag preservation was achieved in 35% of eyes with 65% requiring scleral-haptic fixation (SHF). Mean VA remained at 0.12 logMAR pre- and post-operatively in the IOL exchange group whereas the SHF group worsened from 0.14 to 0.20. All patients reported subjective improvement in vision. CMO occurred in 20.5% of eyes in the SHF group and 1.6% in the IOL exchange group. Mean refractive prediction error was 0.45D in the SHF group and -0.15D in the IOL exchange group with a mean absolute refractive prediction error of 0.62D and 0.57D in the SHF and IOL exchange groups respectively.
Conclusion:
IOL exchange provided favourable visual and refractive outcomes even in eyes where capsular bag preservation was not possible. Post-operative CMO was the main complication in eyes requiring SHF, underscoring the importance of meticulous preoperative counselling and careful perioperative management.

Abstract Title
Update on Ophthalmic Microsurgery Robot (OmSR) as a platform to educate and facilitate robotic surgery.
Purpose
To give an update on the development of the bimanual robotic surgical platform for retinal microsurgery and surgical training simulation.
Setting/Venue
The data collection and initial development were set at Royal Free Hospital London, development was continued at Institute of Ophthtalmology.
Methods
The Ophthalmic Microsurgery Robot (OmSR) is a bimanual robotic platform developed for posterior chamber surgical applications, designed to replicate the natural hand movements of surgeons, with a possibility of future telesurgery. We created a virtual simulation environment to facilitate training and testing, which was evaluated by ophthalmic surgeons with varying levels of experience. We developed and integrated a bespoke OCT system using Leica OCT scanner head to allow for precision depth measurement during the subretinal injections. This is integrated with a custom haptic device controllers for a simulation of virtual boundaries and resistance when piercing the retina in porcine model.
Results
A bespoke OCT system allows for a higher scanning rate than commercial iOCT systems. We introduced an automatic needle detection system to narrow down the scanning window of the OCT engine. The calibration of the engine was performed and a distance estimation was performed for the needle depth in the simulation studies._x000D_
We integrated the developments into the virtual simulator for training surgeons with high success rate.
Conclusion:
The OmSR platform offers a good alternative with a haptic feedback for the depth estimation. The preliminary studies show a promising trajectory for OCT-coupled feedback mechanisms that suit doctors with existing and new experience in the vitreo-retinal space.

Abstract Title
A Scoping Review of the Use of Artificial Intelligence Models in Automated OCT Analysis and Prediction of Treatment Outcomes in Diabetic Macular Oedema
Purpose
To map and critically appraise published applications of artificial-intelligence‚ (AI) algorithms for optical coherence tomography‚ (OCT) in diabetic macular oedema (DMO), focusing on diagnostic accuracy, biomarker segmentation, severity grading, and prediction of visual/anatomical response to anti-VEGF therapy.
Setting/Venue
Systematic scoping review following PRISMA ScR/Cochrane guidance; literature searched across MEDLINE, EMBASE, CENTRAL, Cochrane and Web Science.
Methods
Eligible studies (2000-2024) evaluating AI-based OCT analysis in DMO were identified. Two reviewers independently screened titles/abstracts, extracted data on study design, datasets, OCT device, AI architecture, targeted task (detection, segmentation, grading, outcome prediction) and performance metrics. Methodological quality was scored with the MAIC10 checklist. Descriptive synthesis compared model performance and external validation.
Results
Forty studies met eligibility (28 detection/segmentation, 7 grading, 5 outcome-prediction). Convolutional-neural-network classifiers distinguished DMO from other maculopathies with pooled accuracy 96–99% and AUC ≥ 0.97. Segmentation networks achieved median Dice scores 0.86 for intraretinal fluid (IRF), 0.83 for subretinal fluid (SRF), and 0.79 for hyperreflective foci (HRF). Only six studies employed external datasets, reducing accuracy by 3–8%. Prognostic models combining baseline OCT features predicted ≥10-letter visual gain at 12 months with mean AUC 0.75 but lacked systemic variables.
Conclusion:
AI reaches near-expert accuracy for DMO diagnosis and biomarker segmentation but remains under-validated in diverse populations and underpowered for outcome prediction. Future work should integrate multimodal longitudinal data, harmonise multicentre OCT datasets, and benchmark algorithms against MAIC 10 criteria to enable personalised therapy in routine care.

Abstract Title
Outcomes of tissue plasminogen activator & C3F8 gas for sub macular haemorrhage in 115 consecutive cases from a single centre - analysis of patients treated before and after 14 days post onset
Purpose
Sub-macular haemorrhage (SMH) is a visually devastating condition. It is often secondary to a choroidal neovascular membrane. Tissue plasminogen activator (tPA) can be administered along with intravitreal injection of C3F8 gas to displace the haemorrhage and preserve vision. We present data from a large cohort demonstrating good visual outcomes.
Setting/Venue
This study reports a cohort of patients from New Cross Hospital, Royal Wolverhampton Hospitals NHS Trust, UK.
Methods
Patients undergoing intravitreal tPA/C3F8 from April 2015 to August 2024 were identified and case notes retrospectively analysed. Visual acuity (LogMAR) was recorded at presentation and at 3 and 6 months following treatment. Other data recorded included patient demographics, underlying cause of haemorrhage, concurrent use of antiplatelet or anticoagulant medications, greatest height of sub-macular haemorrhage on OCT imaging, and complications of treatment. Change in visual acuity and sub-macular haemorrhage height were compared between timepoints using a repeated measures ANOVA. Subgroup analyses were performed for patients treated <14 days and ‚â•14 days from onset of bleed.
Results
115 patients (64 female, 51 male) met inclusion criteria. Mean age was 78.7 years. Mean time from symptom onset to presentation was 6.8 days (median 3 days), and from presentation to treatment was 2.7 days (median 1 day). 58/115 (50.43%) patients were on antiplatelet or anticoagulant medications. Mean VA (LogMAR) amongst patients treated <14 days from symptom onset improved from 1.59 to 1.021 at month 3 and 1.01 at month 6 (p<0.001). Mean VA amongst patients treated ‚â•14 days from symptom onset did not significantly improve from 1.37 at baseline to 1.27 and 1.32 at month 3 and 6.
Conclusion:
Intravitreal tPA and C3F8 following SMH is effective within 14 days of onset. Although VA did not improve after 14 days, many patients perceived benefit. VA assessment alone may not capture functional utility of treatment. Further work should investigate benefit in terms of visual field and patient reported outcomes.

Abstract Title
Carry On ... Injecting!_x000D_ Is There Such Thing as an Optimum Number of Intravitreal Injections?
Purpose
Intravitreal injections (IVI's) have revolutionised ophthalmology and their number seems to have grown exponentially. Even though considered safe procedures, endophthalmitis has emerged as one of the most feared and unpredictable complications. Our prospectively gathered data of presumed post-IVI presumed endophthalmitis aims to calculate the cumulative per-eye risk of endophthalmitis.
Setting/Venue
We present a prospective study of 10 years of endophthalmitis following intravitreal injections at the Jules Gonin University Hospital, Switzerland
Methods
Univariate linear logistic regression was used to calculate the increased risk of endophthalmitis related to the number of injections performed in each eye. Patients were stratified according to the total number of injections performed in each eye with a cut-off value of under 60 or over/equal to 60 injections. Multivariate analysis was performed to assess the Odds ratio of increased risk per each injection. (Wald test). _x000D_
Truncated negative binomial regression compared the mean number of injections performed in the last year in the endophthalmitis group to the mean number of injections performed during the last year in the non-endophthalmtis group.
Results
From 2014 to 2023 64743 IVI's have been performed, 26 of which led to endophthalmitis, a rate of 0.04% or one in 2490 injections. The proportion of eyes with presumed endophthalmitis after IVI increases almost ten-fold when the number of injections per eye rises above 60 injections [OR of 9.5]. A significantly increased OR of endophthalmtis is already present after more than 20 injections OR:2.31 (p=0.0341) and 30 injections OR:3.35 (p=0.0023)._x000D_
Truncated negative binomial regression showed the endophthalmitis population having a by 148% increased number of IVI's (IRR=2.48) prior to endophthalmitis as opposed to the non-endophthalmitis group (p < 0.0001).
Conclusion:
Our study (0.04%) managed to replicate the internationally published endophthalmitis rate of around 0.035-0.05%, it is not an outlier. Today's IVI-population is different from 10 years ago. A ten-fold increase in endophthalmitis risk above 60 injections should re-balance the risk/benefit-analysis requiring individual justification in each case and each additional injection.

Abstract Title
Visual Outcomes and Complications Following Phacoemulsification Surgery Performed in the Vitreoretinal Department of a Large Center: Moorfields Vitreoretinal Cataract Study
Purpose
Cataracts referred to vitreoretinal surgeons for phacoemulsification are typically more complex or combined with pars plana vitrectomy. This study aims to evaluate visual outcomes and complications following phacoemulsification surgery undertaken by a vitreoretinal (VR) service at a large tertiary eye center
Setting/Venue
Vitreoretinal surgery service, Moorfields Eye Hospital NHS Foundation Trust, London, UK.
Methods
non-comparative, retrospective case series of phacoemulsification surgery at Moorfields Eye Hospital undertaken between January 1st 2021 and January 1st 2024. Visual outcomes and complications were extracted from the electronic health records and manually validated by vitreoretinal fellows. Primary and secondary outcomes were posterior capsular rupture (PCR) incidence and visual outcomes respectively. Associations between PCR and postoperative visual acuity with pre- and perioperative factors were investigated using univariable and multivariable-adjusted regression models
Results
1,659 were included (mean age 63 ± 14 years). Mean (+/- standard deviation) preoperative and postoperative VA was 1.1+/- 0.73 logMAR, and 0.5 +/- 0.57 logMAR respectively. The PCR rate was 4.2%. Factors associated with postoperative VA were: PCR (+0.15 logMAR, p = 0.009), age (–0.04 per decade, p < 0.001), preoperative VA, and surgical factors such as ERM peel (+0.10 logMAR, p = 0.001), ILM peel (+0.15 logMAR, p = 2.8 × 10⁻⁶), and ROSO (+0.26 logMAR, p = 9.5 × 10⁻¹⁴). The only prognostic factor for PCR was preoperative VA (OR 1.42 per +1.0 logMAR, p = 0.028)
Conclusion:
We present a large series of phacoemulsification surgeries performed in the VR department, characterized by increased risk of complications, and lower visual potential. This is providing valuable data for auditing cataract surgery outcomes in complex VR cases. and a benchmark for visual prognosis in a range of combined VR procedures

Abstract Title
Establishing an indirect indentation and indirect laser retinopexy simulation session
Purpose
To design a simulated teaching session for ophthalmology registrars to teach and improve skills on indirect indented examination and indirect laser retinopexy.
Setting/Venue
Dry lab simulation session in non clinical area of Moorfields Eye Hospital.
Methods
A half-day laser indentation course was designed for ophthalmology registrars (ST3–ST7). Pre-course preparation included laser safety material and online indirect ophthalmoscopy videos. The course took place in a trust-approved teaching room after risk assessment and mitigation. Faculty (ST6–consultant) provided standardised theory and demonstration, supported by an industry representative. Equipment comprised indentable SimulEye models with “replaceable retina” paper, one non-indentable PRP model, Shockett indenters, indirect ophthalmoscopes (including video-enabled), and portable 532 nm laser consoles. Dynamic indentation was simulated with carmellose gel on model sclera. Participant feedback was collected at session end, and refinements were incorporated from previous iterations.
Results
Three sessions (12 delegates total) were delivered in one half-day. Each began with a 30-minute introduction and live demonstration of indirect ophthalmoscopy, followed by individual practice. Delegates then rotated between laser and indentation stations, each staffed by faculty, with hands-on time using both video and standard ophthalmoscopes. Laser teaching included safety discussion and guided practice on model eyes, with opportunities to adjust power, duration, and distance. Feedback was universally positive, with delegates reporting improved confidence in indentation and laser skills. Several highlighted the value of the course and recommended it be delivered earlier and made compulsory in training.
Conclusion:
We have established an easily repeatable and well received hands on simulation course aimed at registrars, for a traditionally difficult to teach and learn skill of indirect ophthalmoscopy and laser retinopexy. This can be replicated in other units to fill identified training gaps

Abstract Title
Repeat intraocular sampling and microbiological testing in infectious endophthalmitis: A 27-year prospective observational study at an Australian statewide tertiary referral centre
Purpose
Endophthalmitis requiring multiple ocular tissue sampling for microbiological testing is uncommon and has not been previously studied. This study aims to analyse cases with at least two ocular tissue samplings and testing of different ocular samples against culture yields.
Setting/Venue
Royal Victorian Eye and Ear Hospital, Melbourne
Methods
A 27-year prospective observational study was conducted using data from the Victorian Endophthalmitis Registry, managed through the REDCap data platform. The study included 314 patients (317 eyes) who underwent repeat sampling, defined as having at least two aqueous or vitreous specimens collected. These cases were selected from a larger cohort of 1484 total endophthalmitis cases over a 27 year period. The primary outcome measures included microbiological culture results from repeat and multiple ocular sample types, along with the identification of isolated microorganisms.
Results
The culture positivity rate from initial samples was 75.7%, and of second intervention was 34.7%. Among the various sample types, initial vitreous taps yielded the highest culture positivity at 72.6%. Notably, 19.5% of eyes with culture-negative results from the first vitreous tap had positive results on repeat sampling. 24.4% of eyes with initially negative vitreous cultures had positive cultures from initial aqueous taps. Additionally, 12.2% of eyes with negative initial vitreous taps yielded positive cultures from vitreous biopsies obtained during vitrectomy. The most commonly isolated organisms were Staphylococcus and Streptococcus species, accounting for 40.4% and 31.3% of cases, respectively.
Conclusion:
Our study shows the utility of repeated ocular tissue sampling in endophthalmitis. The clinical implications are that AC taps are most useful at the time of the initial biopsy. A second sampling is valuable in patients who are initially culture-negative. Surgical specimens contribute to culture yield and enhance culture positivity.

Abstract Title
Ocular Dominance: Is it of any value to the Vitreoretinal Surgeon? A study of Epiretinal Membrane in the dominant eye vs non-dominant eye
Purpose
Ocular dominance is usually the realm of the cataract surgeon. We hypothesise that ocular dominance may influence being symptomatic of epiretinal membrane (ERM). This study aims to determine if a patient’s ocular dominance is associated with referral to vitreoretinal clinic for ERM, or subsequent decision for surgery.
Setting/Venue
Tennent Institute of Ophthalmology, Gartnavel General Hospital, NHS Greater Glasgow and Clyde, Glasgow
Methods
Consecutive patients with new referrals for epiretinal membrane in a single surgeon’s vitreoretinal clinic were tested for ocular dominance as part of clinic assessment for ERM over the six-month period March 2025 - August 2025. Ocular dominance was assessed using the Miles Test.
Results
Of the 18 patients referred for epiretinal membrane assessment during the study period, 72.2% of ERMs were in the patient’s non-dominant eye. This is a statistically significant association between the side of the ERM and the patient’s ocular dominance (p=0.038). 80% of patients with an ERM in their dominant eye proceeded to surgery, whilst 61.3% of those with ERM in their non-dominant eye decided to proceed with surgery (p=0.614).
Conclusion:
This study aimed to assess if patients were more likely to be symptomatic of ERM in their dominant eye. This study revealed that most patients referred to our vitreoretinal service had ERM in their non-dominant eye. This study did not find that ocular dominance influenced being symptomatic of ERM.

Abstract Title
Measuring subjective quality of vision and metamorphopsia before and after epiretinal membrane and macular hole surgery: MQUEST
Purpose
To compare the subjective outcomes of metamorphopsia and quality of vision in patients undergoing epiretinal membrane (ERM) or macular hole (MH) surgery.
Setting/Venue
Department of Ophthalmology, University Hospital of Wales, Cardiff & Vale University Health Board, Cardiff, Wales.
Methods
A cohort of 50 patients undergoing ERM (n=18) or MH (n=32) surgery under the care of the vitreoretinal (VR) service at the University Hospital of Wales (UHW) completed both the metamorphopsia (MeMoQ) and quality of vision (QoV) questionnaires pre- and 2-3 months postoperatively. Additional clinical data including visual acuity (VA; LogMAR) and optical coherence tomography parameters were collected from the participants’ medical records. Raw patient-reported outcome measure (PROM) scores underwent Rasch-scaling to generate a final score.
Results
VA significantly improved on average from 0.800.37 to 0.330.37 (p&lt;0.0001) equating to an improvement of 2.61.6 lines. MeMoQ scores demonstrated a reduction in Rasch-scaled score from -1.231.44 to -3.201.64 logits (p&lt;0.0001) indicating an improvement. In terms of QoV outcomes all three sub-scales demonstrated improvement with significantly reduced scores from pre- to post-operative assessment (Frequency: preoperatively 54.518.2, postoperatively 37.422.7; Severity: preoperatively 45.515.9, postoperatively 30.919.5; Bothersome: preoperatively 48.919.1, postoperatively 30.025.7; All p&lt;0.0001). Six participants reported worse QoV, two also reported worse metamorphopsia via MeMoQ, despite all improving in measured VA (1-3 lines of improvement). Five patients were lost to follow-up.
Conclusion:
ERM and MH surgery was associated with improvement of standard clinical measures as well as patient-reported symptoms of metamorphopsia and quality of vision. However, some patients may report worse quality of vision and metamorphopsia post operatively despite an improved VA, which has important implications for managing patient expectation pre-operatively.

Abstract Title
What factors affect the change in vision after anatomically successful macular hole surgery?
Purpose
Surgery for idiopathic full thickness macular holes (FTMH) has been shown in many studies to be associated with excellent chances of anatomical success and marked visual acuity gain. However the improvement in acuity is known to be quite variable. We explore the factors affecting change in visual acuity.
Setting/Venue
An analysis of the Euretina/BEAVRS database of prospectively collected macular hole surgeries.
Methods
We extracted all cases of idiopathic primary macular hole surgery recorded in the database between 2014 to 2024. We excluded all cases of anatomical failure and those with less than 8 weeks follow-up. The primary outcome considered was change in visual acuity from pre-operative to final post-operative recorded vision. We collected demographic and surgical variables and considered their impact on acuity change. We constructed a multivariate model of all factors found to significantly affect acuity change.
Results
4,959 macular hole surgeries were recorded in the database from 2014 to 2024, 4% were excluded due to primary anatomical failure and 18% excluded due to insufficient follow-up data, leaving 3,861 surgeries included in the study. The median pre-operative vision was 0.78 logMAR and postoperatively the median acuity was 0.40 with median acuity gain of 0.42. The multivariate analysis showed greater acuity gain was seen in younger patients, those of male sex, with worse pre-operative acuity, smaller holes, shorter duration, absence of AMD, pseudophakic at follow-up and surgery performed by a consultant. Posturing and tamponade type were not significant.
Conclusion:
Successful macular hole surgery is associated with considerable visual acuity gain. Though final acuity maybe less those with poor pre-operative acuity experience the greatest gain in vision. Duration of hole is an independent risk factor in acuity gain and are best when performed within 4 months.

Abstract Title
Air versus Gas Tamponade for Repair of Macular Holes: A Meta-analysis
Purpose
This study is the first in the literature to compare the clinical outcomes of air in comparison to gas tamponades in macular hole repair.
Setting/Venue
A systematic review and meta-analysis were conducted as per the PRISMA guidelines.
Methods
All studies comparing air versus gas tamponades in macular hole surgery repair were included, excluding case reports and non-English studies. The primary outcome was postoperative anatomical success rate; secondary outcomes were best-corrected visual acuity and intraocular pressure. Data were extracted using a piloted Excel spreadsheet. Meta-analysis, using Review Manager 5.3 and Excel, calculated odds ratios were used for dichotomous outcomes and mean differences for continuous outcomes. Heterogeneity was assessed with Cochran’s Q test and I². Risk of bias was evaluated using the Cochrane RoB tool and Newcastle-Ottawa Scale.
Results
A literature search retrieved 1381 records and following deduplication and screening, a total of 8 studies were selected which met the eligibility criteria for inclusion. In terms of anatomical success, there was no statistically significant difference in the pooled data for achieving primary anatomical success with air versus gas tamponade (OR = 1.36, [95% confidence intervals (CI) 0.84 to 2.20], P= 0.22. Postoperative BCVA and IOP were reported to be similar at final follow-up. There was a low level of heterogeneity between the studies (I² = 0%). A fixed-effects model was used to account for this heterogeneity.
Conclusion:
This meta-analysis revealed comparable findings between gas and air tamponades in primary anatomical success, postoperative BCVA and IOP. Further studies with larger sample sizes are needed to further evaluate these findings, with particular focus on MH size.

Abstract Title
High-Resolution Optical Coherence Tomography in Pathology of the Vitreomacular Interface
Purpose
This study investigates the diagnostic capabilities of high-resolution optical coherence tomography (HR-OCT) compared to spectral domain optical coherence tomography (SD-OCT) in detecting detailed microstructural changes in vitreomacular pathology.
Setting/Venue
Department of Ophthalmology, Inselspital, Bern University Hospital, University of Bern, Switzerland.
Methods
This was a prospective cross-sectional study of eyes with vitreomacular interface disease. We included patients with epiretinal membrane (ERM), macular hole (MH), lamellar hole (LH), and vitreomacular traction (VMT). Each patient underwent a comprehensive ophthalmic exam followed by retinal imaging with both SD-OCT and HR-OCT. Images were analyzed for the presence of key biomarkers and the two OCT modalities were compared.
Results
18 patients with a mean age of 66 years (SD 8.9), 61.1% were male. HR-OCT provided a superior subcellular view, including superior identification of rod cell nuclei in the outer nuclear layer (ONL), ganglion cell layer (GCL) and enhanced visualization of biomarkers, such as the "cotton ball sign" coupled with IZ disruption (33.3% vs 5.6% for HR-OCT and SD-OCT groups, p = 0.0042). Hyporeflective dots in the ONL, indicative of rod cell nuclei, were seen in 88.9% of HR-OCT cases but were completely undetectable with SD-OCT (p < 0.0001). Cohen’s Kappa values for most biomarkers ranged from 0.78 to 0.89.
Conclusion:
HR-OCT significantly improves the detection of subcellular features and biomarkers in vitreomacular interface disorders. This device could enhance early diagnosis and monitoring of vitreomacular diseases, with potential correlations to functional outcomes.

Abstract Title
Incidence Rates of Severe Vision Loss after Pars Plana Vitrectomy for Retinal Detachment and Full Thickness Macular Hole
Purpose
Outcomes of pars plana vitrectomy (PPV) are conventionally measured by objective outcomes such as best corrected visual acuity (BCVA) correlated to patients perceived visual function and quality of life. This study determined the incidence for severe vision loss after PPV for retinal detachments (RD) and full thickness macular holes (FTMH).
Setting/Venue
An epidemiological retrospective analysis of patient visual outcomes after PPV from data collected on the BEAVRS vitreoretinal database.
Methods
This retrospective analysis was conducted with 8203 cases of RD and 4959 cases of FTMH after repair with PPV. Data was collected on patient age, gender, characteristics of RD cases including macula status, proliferative vitreoretinopathy (PVR) as well as size of, and closure of macular holes for FTMH cases. Post-operative BCVA measurements recorded after complete gas dissolution. Incidence of SVL were thus calculated from the number of patients losing more than 6 lines of vision on logMAR.
Results
Overall incidences of SVL were 2.82% in the RD group and 0.83% in FTMH group. In RD, SVL was greater in those with PVR stage C: 5.36% compared to 2.66%. 13.33% of RD repair failure had SVL, where only 1.44% SVL was seen in successful RD repairs. Opened FTMH observed SVL at 8.91%, where closed cases had rates of only 0.48%. PVR and failure in RD as well as hole size and lack of closure in full thickness macula holes are likely covariates. Finally, some patients may have post-operative progression and development of cataracts, which may account for worsening BCVA.
Conclusion:
This study highlights the current incidence rates of SVL in patients after PPV for RD and FTMH. Surgeons could use these data to inform their consent process and discuss the risks of surgery in tangible terms.

Abstract Title
Outcomes of Scleral Buckling in Paediatric Rhegmatogenous Retinal Detachment: The Manchester Buckle Study
Purpose
To describe the anatomical and functional outcomes of paediatric rhegmatogenous retinal detachment (RRD) managed primarily with scleral buckle and to identify factors predicting single-surgery anatomical success (SSAS) and postoperative best-recorded visual acuity (BRVA).
Setting/Venue
Manchester Royal Eye Hospital.
Methods
A retrospective review was conducted of 49 patients (≤18 years) who underwent primary scleral buckle for RRD between 2008 and 2023. Data on patient and RRD characteristics, ocular comorbidities, surgical technique, complications, and postoperative outcomes were collected. SSAS, final anatomical success, and BRVA were assessed.
Results
Mean age at surgery was 12 ± 3 years, with macula-off detachment in 57% (28/49). SSAS after scleral buckle was achieved in 71% (35/49), and with reoperation (mostly vitrectomy; 13/14), final anatomical success reached 96% (47/49). On multivariable analysis, older age independently predicted higher SSAS (OR 1.41, 95% CI 1.05–1.91, p = 0.023), whereas macula status, drainage, and trauma were not independent predictors. For postoperative BRVA, older age was associated with better BRVA (B = −0.162, p < 0.001), while macula-off status predicted worse BRVA (B = 0.520, p = 0.041). Drainage and trauma were not significant predictors.
Conclusion:
Primary scleral buckle, with secondary vitrectomy if needed, is effective for paediatric RRD, yielding a 71% SSAS and 96% final anatomical success. Older age was independently associated with higher SSAS and better postoperative BRVA, while macula-off presentation was associated with worse postoperative BRVA.

Abstract Title
Analysing the frequency of hospital admissions for retinal detachment and vitreo-retinal surgery in England 2000-2024: the COVID-19 pandemic effect and recovery.
Purpose
To analyse changes in admissions and surgery for retinal detachment in England using national data on surgical activity, focusing on three periods: pre-pandemic (2000–2019), the COVID-19 pandemic (2020–21), and post-pandemic (2022-24).
Setting/Venue
National epidemiological study using Hospital Episode Statistics (HES) and Office for National Statistics (ONS) population denominators.
Methods
Hospital Episode Statistics were interrogated for rhegmatogenous retinal detachment (H33.0) and tractional detachment (H33.4), together with pars plana vitrectomy (C79.2 and composite) and scleral buckle (C54.x) codes between 2000–2024. ONS mid-year estimates provided denominators to calculate annual admission rates per 100,000. Trends were analysed across three periods: pre-pandemic (2000–2019), pandemic (2020–21), and post-pandemic (2022–2024). Ratios of buckle-to-RD and vitrectomy-to-RD were derived.
Results
From 2000–2019, RD admissions rose from 3,447 (7.0/100k) to 12,427 (22.1/100k). PPV increased over fourfold to ~28,700, while scleral buckle fell from 2,897 to ~770 (&lt;7% of RD surgery). In 2020–21, RD admissions fell to 10,496 (18.6/100k, –18% vs 2019–20) and PPV to 22,198 (–23%). By 2022–24, RD admissions rebounded to 14,878 (25.7/100k), exceeding pre-pandemic levels; PPV volumes recovered to ~29,100. Buckle use remained &lt;5%. Cumulative case numbers, however, lagged behind projected pre-pandemic trajectories, representing approximately two years’ “lost activity.”
Conclusion:
Retinal detachment admissions and PPV volumes have continued to rise in England, while scleral buckling has reduced precipitously before stabilising at a low rate. COVID-19 caused major but transient disruption, with recovery by 2023–24. Persistent cumulative case deficit highlights challenges for service planning, backlog management, and training.

Abstract Title
Macular oedema in retinal detachment complicated by proliferative vitreoretinopathy: causal factors, prognosis and treatment
Purpose
To identify the causes, evaluate prognosis, and explore potential preventive strategies for macular oedema (MO) in patients with retinal detachment (RRD) complicated by proliferative vitreoretinopathy (PVR) repaired by pars plana vitrectomy (PPV) and silicone oil (SO) tamponade.
Setting/Venue
Moorfields Eye Hospital NHS Foundation Trust.
Methods
This post-hoc analysis examined patients from a phase IIIb, single-center, participant-blinded, prospective, randomized, controlled study that evaluated the efficacy of slow-release dexamethasone implant in patients with proliferative vitreoretinopathy (PVR) associated with rhegmatogenous retinal detachment (RRD). Patients were randomized 1:1 to receive either placebo or dexamethasone implant. The study included 140 eyes with established PVR-C that underwent PPV with silicone oil tamponade. Fifty percent (70 eyes) received a dexamethasone implant at the end of surgery.
Results
The prevalence of macular oedema increased over the follow-up period: 20% at 10 days, 40% at 3 months, 51% at 6 months and 59% at 12 months postoperatively. Outer plexiform layer (OPL) thickness increased from a mean of 32.94μm (SD 31.56) to 73.47μm (SD 72.36). A logistic regression model found each additional surgery increased the odds of cystoid macular edema by 30%, a retinectomy increased the risk of MO by 7.2 times. Using a dexamethasone implant at the end of surgery reduced the risk by 29%, and a pre-operative attached macula reduced the odds by 65%.
Conclusion:
Our analysis identified key risk factors for MO at 3 months postoperatively, including multiple surgeries and retinectomy. Conversely, protective factors included the use of a dexamethasone implant and a pre-operatively attached macula. These findings help predict patients at high risk of MO and may aid preventive strategies in PVR-related RRD.

Abstract Title
Human Factors Influencing Compliance with Post-Operative Posturing After Retinal Detachment Surgery: A Tertiary Centre Observational Study
Purpose
To assess patient-related and human factors influencing compliance with prescribed post-operative posturing following retinal detachment repair.
Setting/Venue
Vitreoretinal Service, University Hospitals Bristol and Weston NHS Foundation Trust.
Methods
Single-centre cross-sectional study of patients one week post retinal detachment repair with gas tamponade. Structured questionnaires and clinical records were used to assess compliance. Factors included age, comorbidities, social support, understanding of instructions, physical discomfort, occupational/psychological barriers, with qualitative data obtained via telephone interviews.
Results
40 patients (mean age 62, majority employed) participated. While all reported overall compliance, many required clarification post-discharge due to forgetting or misplacing written instructions. Successful adherence was linked to family or partners, who were present during explanation of posturing, reinforcing instructions at home. Patients described difficulty retaining guidance immediately after surgery, even when written materials were provided. Other barriers included unclear handwriting and physical limitations from pre-existing spinal conditions. Side posturing was generally well tolerated, whereas strict face-down positioning was more challenging.
Conclusion:
Compliance is shaped by cognitive, physical, and social factors. Patients living alone without support appear at higher risk of poor adherence. Tailored counselling with specific engagement of partners and/or present family members, clearer written communication, video instructions, and alternative posturing protocols may improve adherence.

Abstract Title
Pneumatic retinopexy made easy: conclusions from a case series
Purpose
To present outcomes of pneumatic retinopexy with simplified single procedure approach
Setting/Venue
Sheffield Teaching Hospitals NHS Foundation Trust and Nottingham University Hospitals NHS Trust
Methods
A consecutive case series of 25 patients,( 14 male, 11 female, age: 36-83) who underwent pneumatic retinopexy (PR) for rhegmatogenous retinal detachment. Patients who were considered for pneumatic retinopexy met criteria from PIVOT trial. All of them underwent cryotherapy to the retinal tear, followed by anterior chamber parenthesis and insertion of gas tamponade into the vitreous cavity. All procedures were performed by a single surgeon. The patients were followed up for 6 months (apart form a most recent case)
Results
Successful retinal reattachment was in 21/25 patients (84%). Majority of patients had breaks in 2 superior clock hours, where success rate was 15/17 (88.2%).In patients who had breaks in the 4 superior quadrants,11-2 o’clock, the success rate was 19/21 (90.5%). Worse success rate was in patients with breaks around horizontal meridian (50%). PR on 1 patient with a break at 8 o’clock, failed. Two patients were pseudophacic, both had failed procedures. There was no case of proliferative vitreoretinopathy or significant epiretinal membrane. All patents who underwent secondary surgery, had successful reattachment. Mean vision improved form 0,27LogMAR to 0,09LogMAR.
Conclusion:
PR with cryotherapy is a safe and efficient technique of retinal detachment repair. It seem to work best if the breaks are located in 4 superior clock hours and in phakic eyes. Good success rate, low cost, short time required, make it an attractive alternative to vitrectomy in selected cases.

Abstract Title
Epiretinal Membrane and Cystoid Macular Oedema After Vitrectomy for Giant Retinal Tear/Related Retinal Detachment: The Manchester GRT Study
Purpose
To determine the incidence, predictive factors, and visual impact of postoperative epiretinal membrane (ERM) and cystoid macular oedema (CMO) following primary pars plana vitrectomy (PPV) for giant retinal tear/related rhegmatogenous retinal detachment (GRT-RRD).
Setting/Venue
A retrospective, single-centre review was conducted at the vitreoretinal service of Manchester Royal Eye Hospital.
Methods
We retrospectively reviewed 110 patients who underwent primary PPV for GRT-RRD (2012–2024). Collected data included demographics, preoperative characteristics, intraoperative details, and postoperative outcomes. ERM and CMO were assessed with optical coherence tomography (OCT). Predictors of ERM and CMO were analysed using multivariable logistic regression. Best-recorded visual acuity (BRVA) and central retinal thickness (CRT) were compared between groups using nonparametric tests.
Results
ERM developed in 60% (54/90) and CMO in 23.6% (26/88) of eyes. Seven patients underwent ERM peel during follow-up, and three received sub-Tenon or intravitreal steroid treatment for CMO. In multivariable analysis, ERM was associated with trauma (OR 39.2, p = 0.022) and greater RRD extent (per clock hour; OR 1.49, p = 0.019). Protective factors included Indo-Aryan ethnicity (OR 0.03, p = 0.016) and myopia (OR 0.09, p = 0.003). No covariates predicted CMO. Both ERM and CMO were associated with increased postoperative CRT (p < 0.05) but did not significantly affect final BRVA.
Conclusion:
Postoperative ERM occurs more often in GRT-RRDs than non-GRT-RRDs, while CMO rates are comparable. Postoperative ERM was associated with trauma, greater RRD extent, absence of myopia, and ethnicity, whereas no CMO predictors were identified. Despite retinal thickening, final BRVA remained unaffected. Primary ILM peeling may be useful in select cases.

Abstract Title
To Drain or Not to Drain? The Manchester Buckle Study
Purpose
To assess whether external drainage of subretinal fluid (SRF) improves anatomical or visual outcomes in scleral buckle surgery for rhegmatogenous retinal detachment (RRD).
Setting/Venue
Manchester Royal Eye Hospital.
Methods
Retrospective review of 609 primary scleral buckles performed between 2008 and 2023. Pre/intra-operative characteristics, drainage use, best-recorded visual acuity (BRVA) and single-surgery anatomical success (SSAS) were analysed.
Results
A total of 609 patients were analysed: 428 without SRF drainage and 181 with drainage. Groups were similar in age (p=0.33), baseline BRVA (p=0.47), RRD type (p=0.17), high myopia (p=0.52), and trauma (p=0.06). The drainage group had more macula-off RRDs (48% vs. 39%, p=0.05) and more procedures were performed by consultants (p&lt;0.01). SSAS rates were similar (86.7% with drainage vs. 83.6% without,p=0.67). Final BRVA showed no significant differences overall (p=0.47) or within macula-on/off subgroups. Drainage caused subretinal haemorrhage in 34 eyes (18.8%), almost all (32) small and localised to the drainage site; no endophthalmitis, retinal incarceration or vitreous loss occurred.
Conclusion:
External SRF drainage during scleral buckling is safe but did not improve SSAS or BCVA. Routine use is unwarranted, though it remains helpful for highly bullous or extensive detachments.

Abstract Title
Scleral Rupture during Cryo-retinopexy: A Case Series
Purpose
To report the clinical outcomes of patients who experienced scleral rupture following cryo-retinopexy, and to highlight potential risk factors, management strategies, and prognosis.
Setting/Venue
BEACON Project
Methods
This retrospective case series includes patients who developed scleral rupture during cryo-retinopexy for symptomatic retinal tear(s) across multiple ophthalmology units in the UK and internationally, between September 2003 and March 2025. Data collected included patient demographics, medical and ocular history, clinical examination findings, details related to the scleral rupture, surgical management, and postoperative outcomes.
Results
Four cases of scleral perforation were included in this series. The median age was 56 years, with an equal distribution of males and females. All patients underwent scleral repair and pars plana vitrectomy with silicone oil tamponade. The final visual acuity was 20/25 in three patients and 20/200 in one. None of the cases had a history of systemic disorders, while myopia was noted in three patients.
Conclusion:
Immediate scleral rupture repair combined with pars plana vitrectomy and silicone oil tamponade is the preferred management approach and is associated with favourable postoperative outcomes. Myopia may represent a potential risk factor for scleral rupture. Comprehensive patient counselling and informed consent are crucial when planning cryo-retinopexy.

Abstract Title
Two-Year Outcomes of Air compared to Sulphur Hexafluoride as a Tamponade in Primary Rhegmatogenous Retinal Detachment Repair: Experience from the West of Scotland
Purpose
To evaluate the anatomical and visual outcomes of pars plana vitrectomy with cryoretinopexy and air versus sulphur hexafluoride (SF6) gas tamponade for primary rhegmatogenous retinal detachment (RD) over a two-year period in a tertiary centre in Scotland.
Setting/Venue
Gartnavel General Hospital, Glasgow, United Kingdom.
Methods
We conducted a retrospective review of all primary RD repaired with pars plana vitrectomy, cryoretinopexy, with Air or SF6 gas tamponade between March 2023 and March 2025. _x000D_
All patients had immediate postoperative face down posturing for 1-2 hours followed by targeted positioning for 36 hours. Demographics, macular status, causative break location, anatomical success, and visual acuity outcomes were analysed.
Results
We had 47 patients in the Air group: 59.6% male, 70.2% phakic, 61.7% macula-on. Primary success was 87.2% overall, 89.7% for macula-on, and 83.3% for macula-off detachments. Median visual acuity (VA) improved from 0.20 LogMar preoperatively to 0.10 at final follow-up (p=0.0099)._x000D_
There were 21 patients in the SF6 group: 59.1% male, 90.9% phakic, 59.1% macula-on. The primary success rate was 90.9% overall, 92.3% for macula-on, and 83.3% for macula-off. Median preoperative VA was 0.16 and the final postop VA was 0.2 (p < 0.05)_x000D_
There was no statistically significant difference in the success rate between both groups.
Conclusion:
Air tamponade is as safe and effective as SF6 gas for selected primary retinal detachments, providing high anatomical success, faster visual recovery, and environmental advantages. Our results demonstrate favourable outcomes even without heavy liquid and laser retinopexy previously reported, supporting air as a viable alternative in appropriately selected cases.

Abstract Title
Timing of Retinal Detachment after Open Globe Injuries
Purpose
Open globe injuries (OGI) need not always be devastating, but past the primary repair is the threat of retinal detachment (RD) which often heralds a poor outcome. We set out to assess the prevalence of retinal detachment following OGI, the time of onset and features.
Setting/Venue
7 year analysis of OGI primary repairs at Imperial College London NHS Healthcare Trust, an ophthalmic emergency regional referral centre.
Methods
Retrospective review of electronic and paper patient records for emergency ophthalmology procedures performed between 1st March 2015 and 31 December 2022. Inclusions were based on procedure title and subsequent review of notes. Anonymised data was gathered into a purpose designed audit tool on Microsoft Excel, with patient demographics, nature of injury, examination findings, best corrected visual actuity (BCVA) and structural outcomes recorded. Patients followed up for less than 2 months and those who underwent enucleation were excluded from analysis of visual or structural outcome but still included in baseline and demographic analysis
Results
123 eyes of 122 patients were included. 101 satisfied criteria for outcome analysis. _x000D_
32(31.6) were diagnosed with RD at any time and 38(37.6%) with vitreous haemorrhage (VH). Of those with VH, 20(52.6%) had RD at any time._x000D_
Of all detachments included in outcome analysis, 15(52%) were diagnosed by postoperative day 7, 24(85.7%) by day 21 and 26(92.3%) by day 42. Median final BCVA for all was 6/24 and hand movements for those with RD._x000D_
Median time to RD diagnosis was 6.5 days for entire cohort, 6 days for those with VH, and 14 days for those without.
Conclusion:
RD can complicate around a third of OGI, increasing to around a half of all those with VH. Nearly all are detached by week 5 of follow-up. This identifies a crucial follow-up period whereby regular and frequent posterior examination may identify early detachments, permitting prompt management and potentially improved outcomes.

Abstract Title
Conflict-Zone Ophthalmology; A report of two vitreoretinal surgical missions to Gaza strip between May and August 2025
Purpose
To report the experience of 2 UK-based vitreoretinal surgeons who visited Gaza on two 15-day voluntary visits between May and August 2025; during which clinical and surgical care was provided to the civilian population currently experiencing the effects of the ongoing conflict.
Setting/Venue
Clinics and theatres in Nasser and Al-Amal Hospitals (Khan-Younis) and Gaza Ophthalmic hospital (Gaza city) between May and August 2025.
Methods
Retrospective review of VR clinics and theatre lists. The aim is to report on the different clinical presentations and surgeries performed during both visits, highlighting the challenges to provision of care.
Results
357 patients were reviewed, 67 underwent surgery, 25 in the first and 42 in the second visit (79% male; mean age 37.9 years [1–75, ±18.1]; 16.4%< 18). Trauma accounted for 45 % (n=30), mainly intraocular foreign body (n=15) and vitreous haemorrhage (n=4). Among 37 non-traumatic cases, rhegmatogenous retinal detachment (n=10) and silicone-oil–filled globe (n=13) predominated. Most surgeries occurred in the South (69%). Where tamponade was required, only silicone oil was used. Single-use surgical supplies were re-sterilized and reused. No cases of postoperative endophthalmitis were reported. Among the 81% not operated, many were inoperable due to advanced presentation and treatment delay.
Conclusion:
The visits supported local teams who, despite humanitarian and logistical challenges, organized preoperative clinics and continued to maintain postoperative care. Local vitreoretinal surgeons continue to operate on patients not managed during the visits. These 2 successive visits were coordinated which allowed more surgeries and higher impact in the second visit.
