Abstract
PURPOSE To assess efficacy and safety outcomes of subretinal fluid drainage methods during pars plana vitrectomy for rhegmatogenous retinal detachment. METHODS A systematic search strategy was conducted for studies published between January 2000 and October 2022. Included studies reported on either the safety or efficacy of two or more drainage methods during pars plana vitrectomy for patients with rhegmatogenous retinal detachment. RESULTS Two randomized and five observational studies consisting of 1,524 eyes were included. Best-corrected visual acuity at the last study observation and primary reattachment rates were similar across groups. A significantly lower risk of epiretinal membrane formation was associated with draining subretinal fluid through preexisting retinal breaks (risk ratio = 0.70, 95% confidence interval = [0.60, 0.83], P = <0.01, I 2 = 0%) or with perfluorocarbon liquid (risk ratios = 0.70, 95% confidence interval = [0.59, 0.83], P = <0.01, I 2 = 0%) compared with posterior retinotomy. The risk of an abnormal foveal contour was significantly greater in perfluorocarbon liquid-treated eyes relative to posterior retinotomy (risk ratios = 1.56, 95% confidence interval = [1.13, 2.17], P = <0.01, I 2 = 0%). CONCLUSION No significant differences were observed in the final best-corrected visual acuity at the last study observation and primary reattachment rates across different drainage methods. There remains limited information on the topic, so future research is warranted.

Abstract
PURPOSE To evaluate outer retinal recovery on postoperative optical coherence tomography (OCT) based on presenting morphologic stage of rhegmatogenous retinal detachment (RRD). METHODS Retrospective cohort of consecutive primary fovea-involving RRDs, referred from January 2012 to September 2022. Baseline OCTs were assessed for morphologic stage of RRD. Postoperative OCT scans were graded at 3, 6, and 12 months for external limiting membrane, ellipsoid zone and interdigitation zone discontinuity, epiretinal membrane formation and severity, and residual subfoveal fluid. RESULTS Three hundred and fifty-one patients were included. Increasing baseline morphologic stage of RRD was significantly associated with external limiting membrane, ellipsoid zone, and interdigitation zone discontinuity at all time points postoperatively ( P < 0.001) and was shown to be an independent predictor of foveal photoreceptor integrity after adjusting for height of detachment, time to surgery, and duration of fovea involvement ( P < 0.001). Earlier stages were associated with residual subfoveal fluid ( P < 0.001). There was no association between the stages of RRD and epiretinal membrane severity. However, late stages presented with earlier development of epiretinal membrane ( P = 0.012). CONCLUSION Increasing morphologic stage of RRD is associated with delayed recovery of outer retinal bands in the first year and faster development of epiretinal membrane after RRD repair. The results of this study suggest that the stages may serve as a prognostic biomarker for postoperative photoreceptor recovery.

Abstract
Primary vitreoretinal lymphoma is a potentially aggressive intraocular malignancy with poor systemic prognosis and sometimes significant diagnostic delays as it may masquerade as chronic uveitis. Despite the variety of diagnostic techniques, it is unclear which modality is most accurate in the diagnosis of PVRL. A systematic literature search was conducted on Ovid MEDLINE, EMBASE and the Cochrane Controlled Register of Trials for studies published between January, 2000, and June, 2023. Randomized controlled trials (RCTs) reporting on the following diagnostic tools used to diagnose patients with PVRL were included: cytology, flow cytometry, MYD88 L265P mutation, CD79B mutation, interleukin 10/interleukin-6 (IL-10/IL-6) ratio, polymerase chain reaction (PCR) for monoclonal immunoglobulin heavy chain (IgH) and immunoglobulin kappa light chain (IgK) rearrangements, and imaging findings. The aggregated sensitivity of each diagnostic modality was reported and compared using the chi-squared (χ2) test. A total of 662 eyes from 29 retrospective studies reporting on patients diagnosed with PVRL were included. An IL-10/IL-6 ratio greater than 1 had the highest sensitivity (89.39%, n = 278/311 eyes, n = 16 studies) for PVRL, where the sensitivity was not significantly different when only vitreous samples were drawn (88.89%, n = 232/261 eyes, n = 13 studies) compared to aqueous samples (83.33%, n = 20/24, n = 2) (p = 0.42). Flow cytometry of vitreous samples gave a positive result in 66/75 eyes (88.00%, n = 6 studies) with PVRL, and monoclonal IgH rearrangements on PCR gave a positive result in 354/416 eyes (85.10%, n = 20 studies) with PVRL. MYD88 L265P and CD79B mutation analysis performed poorly, yielding a positive result in 63/90 eyes (70.00%, n = 8 studies) with PVRL, and 20/57 eyes (35.09%, n = 4 studies) with PVRL, respectively. Overall, our systematic review found that an IL-10/IL-6 ratio greater or equal to one may provide the highest sensitivity in identifying patients with PVRL. Future studies are needed to employ multiple diagnostic tools to aid in the detection of PVRL and to further establish nuanced guidelines when determining the optimal diagnostic tool to use in diverse patient populations.

Abstract
PURPOSE With the popularization of ChatGPT (Open AI, San Francisco, California, United States) in recent months, understanding the potential of artificial intelligence (AI) chatbots in a medical context is important. Our study aims to evaluate Google Gemini and Bard's (Google, Mountain View, California, United States) knowledge in ophthalmology. METHODS In this study, we evaluated Google Gemini and Bard's performance on EyeQuiz, a platform containing ophthalmology board certification examination practice questions, when used from the United States (US). Accuracy, response length, response time, and provision of explanations were evaluated. Subspecialty-specific performance was noted. A secondary analysis was conducted using Bard from Vietnam, and Gemini from Vietnam, Brazil, and the Netherlands. RESULTS Overall, Google Gemini and Bard both had accuracies of 71% across 150 text-based multiple-choice questions. The secondary analysis revealed an accuracy of 67% using Bard from Vietnam, with 32 questions (21%) answered differently than when using Bard from the US. Moreover, the Vietnam version of Gemini achieved an accuracy of 74%, with 23 (15%) answered differently than the US version of Gemini. While the Brazil (68%) and Netherlands (65%) versions of Gemini performed slightly worse than the US version, differences in performance across the various country-specific versions of Bard and Gemini were not statistically significant. CONCLUSION Google Gemini and Bard had an acceptable performance in responding to ophthalmology board examination practice questions. Subtle variability was noted in the performance of the chatbots across different countries. The chatbots also tended to provide a confident explanation even when providing an incorrect answer.

Abstract
PURPOSE Manual extraction of spectral domain optical coherence tomography (SD-OCT) reports is time and resource intensive. This study aimed to develop an optical character recognition (OCR) algorithm for automated data extraction from Cirrus SD-OCT macular cube reports. METHODS SD-OCT monocular macular cube reports (n = 675) were randomly selected from a single-center database of patients from 2020 to 2023. Image processing and bounding box operations were performed, and Tesseract (an OCR library) was used to develop the algorithm, OCTess. The algorithm was validated using a separate test data set. RESULTS The long short-term memory deep learning version of Tesseract achieved the best performance. After reverifying all discrepancies between human and algorithmic data extractions, OCTess achieved accuracies of 100.00% and 99.98% in the training (n = 125) and testing (n = 550) datasets, while the human error rate was 1.11% (98.89% accuracy) and 0.49% (99.51% accuracy) in each, respectively. OCTess extracted data in 3.1 seconds, compared with 94.3 seconds per report for human evaluators. CONCLUSION We developed an OCR and machine learning algorithm that extracted SD-OCT data with near-perfect accuracy, outperforming humans in both accuracy and efficiency. This algorithm can be used for efficient construction of large-scale SD-OCT data sets for researchers and clinicians.

Abstract
BACKGROUND The efficacy and safety of initial tap and inject (T/I) compared with pars plana vitrectomy (PPV) for acute postoperative bacterial endophthalmitis following cataract surgery is unclear. Understanding the comparative safety and efficacy of initial T/I and initial PPV can provide context for treatment decision making in this setting. METHODS A systematic literature search was performed on Ovid MEDLINE, EMBASE, and the Cochrane Library from January 1990 to January 2021. Comparative studies reporting on final best-corrected visual acuity (BCVA) following initial T/I or PPV in patients with infectious endophthalmitis secondary to cataract surgery were included. Cochrane's Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-I) was used to evaluate the risk of bias, and GRADE criteria were used to assess certainty of evidence. A random-effects model was used for meta-analysis. RESULTS Seven nonrandomized studies reporting on 188 eyes at baseline were included in this meta-analysis. Initial T/I achieved a significantly better BCVA at last study observation than initial PPV (weighted mean difference [WMD] = -0.61 logMAR; 95% CI, -1.19 to -0.03; p = 0.04; I2 = 89%; n = 7 studies; GRADE = very low). The incidence of enucleation was similar between initial T/I and initial PPV (risk ratio [RR] = 0.73; 95% CI, 0.09-6.25; p = 0.78; I2 = 4%; n = 2 studies; GRADE = very low). The risk of retinal detachment was similar between treatment modalities (RR = 0.29; 95% CI, 0.01-5.94; p = 0.42; I2 = 52%; n = 2 studies; GRADE = very low). CONCLUSIONS The quality of evidence in this setting is limited. T/I had a significantly better BCVA at last study observation than initial PPV. Safety profiles were similar between T/I and PPV.

Abstract
PURPOSE To our knowledge, we present the first case series investigating the relationship between adaptive optics (AO) imaging and intravenous fluorescein angiography (IVFA) parameters in patients with diabetic retinopathy. METHODS Consecutive patients with diabetic retinopathy older than age 18 years presenting to a single center in Toronto, Canada, from 2020 to 2021 were recruited. Adaptive optics was performed with the RTX1 camera (Imagine Eyes, Orsay, France) at retinal eccentricities of 2° and 4°. Intravenous fluorescein angiography was assessed with the artificial intelligence-based RETICAD system to extract blood flow, perfusion, and blood-retinal-barrier (BRB) permeability at the same retinal locations. Correlations between AO and IVFA parameters were calculated using Pearson's correlation coefficient. RESULTS Across nine cases, a significant positive correlation existed between photoreceptor spacing on AO and BRB permeability (r = 0.303, P = 0.027), as well as perfusion (r = 0.272, P = 0.049) on IVFA. When stratified by location, a significant positive correlation between photoreceptor dispersion and both BRB permeability and perfusion (r = 0.770, P = 0.043; r = 0.846, P = 0.034, respectively) was observed. Cone density was also negatively correlated with BRB permeability (r = -0.819, P = 0.046). CONCLUSION Photoreceptor spacing on AO was significantly correlated with BRB permeability and perfusion on IVFA in patients with diabetic retinopathy. Future studies with larger sample sizes are needed to understand the relationship between AO and IVFA parameters in diverse patient populations.

Abstract
Importance Ophthalmology is reliant on effective interpretation of multimodal imaging to ensure diagnostic accuracy. The new ability of ChatGPT-4 (OpenAI) to interpret ophthalmic images has not yet been explored. Objective To evaluate the performance of the novel release of an artificial intelligence chatbot that is capable of processing imaging data. Design, Setting, and Participants This cross-sectional study used a publicly available dataset of ophthalmic cases from OCTCases, a medical education platform based out of the Department of Ophthalmology and Vision Sciences at the University of Toronto, with accompanying clinical multimodal imaging and multiple-choice questions. Across 137 available cases, 136 contained multiple-choice questions (99%). Exposures The chatbot answered questions requiring multimodal input from October 16 to October 23, 2023. Main Outcomes and Measures The primary outcome was the accuracy of the chatbot in answering multiple-choice questions pertaining to image recognition in ophthalmic cases, measured as the proportion of correct responses. χ2 Tests were conducted to compare the proportion of correct responses across different ophthalmic subspecialties. Results A total of 429 multiple-choice questions from 136 ophthalmic cases and 448 images were included in the analysis. The chatbot answered 299 of multiple-choice questions correctly across all cases (70%). The chatbot's performance was better on retina questions than neuro-ophthalmology questions (77% vs 58%; difference = 18%; 95% CI, 7.5%-29.4%; χ21 = 11.4; P < .001). The chatbot achieved a better performance on nonimage-based questions compared with image-based questions (82% vs 65%; difference = 17%; 95% CI, 7.8%-25.1%; χ21 = 12.2; P < .001).The chatbot performed best on questions in the retina category (77% correct) and poorest in the neuro-ophthalmology category (58% correct). The chatbot demonstrated intermediate performance on questions from the ocular oncology (72% correct), pediatric ophthalmology (68% correct), uveitis (67% correct), and glaucoma (61% correct) categories. Conclusions and Relevance In this study, the recent version of the chatbot accurately responded to approximately two-thirds of multiple-choice questions pertaining to ophthalmic cases based on imaging interpretation. The multimodal chatbot performed better on questions that did not rely on the interpretation of imaging modalities. As the use of multimodal chatbots becomes increasingly widespread, it is imperative to stress their appropriate integration within medical contexts.

Abstract
The DRAIN STUDY evaluated a novel use of a 38-gauge Polytip® cannula for posteriorly trapped intraoperative subretinal fluid endo-drainage during pars plana vitrectomy in rhegmatogenous retinal detachment. Sixteen patients underwent this procedure, with an 81% single surgery success rate at 3 months postoperatively. Median visual acuity improved from 20/300 to 20/80. Two cases developed cystoid macular edema and epiretinal membrane. No postoperative residual subretinal fluid was observed. The 38-gauge cannula-based SRF drainage proved effective, offering an alternative to conventional methods for managing posteriorly trapped intraoperative subretinal fluid.

Abstract
BACKGROUND AND OBJECTIVE Relationships between disease and treatment factors of diabetes and vision difficulty remain largely unknown. This study investigated the relationship between disease and treatment factors in diabetes and participants' self-reported vision difficulty. PATIENTS AND METHODS This was a cross-sectional, population-based analysis. Data from the National Health Interview Survey was used and analyzed through univariable and multivariable logistic regression. RESULTS From the 29,464 included participants, logistic regression showed increased odds of self-reported vision difficulty among participants with diabetes (odds ratio [OR] = 2.14, P < 0.001), prediabetes (OR = 1.95, P < 0.001), or gestational diabetes (OR = 1.54, P < 0.001) compared to participants without diabetes. Those who reported having diabetes for more than a year had higher odds of vision difficulty (OR = 1.97, P = 0.02), as did those who were taking insulin (OR = 1.62, P < 0.001), those who had taken less insulin to save money within the past year (OR = 1.87, P = 0.01), and those who reported experiencing diabetes-related stress (OR = 2.14, P < 0.001). CONCLUSIONS Duration of diabetes, diabetes-related stress, and taking less insulin than recommended to save money were associated with vision difficulty.

Abstract
BACKGROUND AND OBJECTIVE This review consolidates findings from studies that used a preoperative visual acuity (VA) threshold as an indication for epiretinal membrane (ERM) surgery. METHODS The literature was systematically searched using Ovid MEDLINE, EMBASE, and Cochrane Library from January 2000 to October 2022 to select studies reporting on pars plana vitrectomy (PPV) for ERM that used a preoperative VA threshold as an inclusion criterion. Primary outcomes were final best-corrected visual acuity (BCVA) and change in BCVA relative to baseline. Secondary outcomes included risk of intra- and postoperative complications. RESULTS A total of 639 eyes from seven studies were included. The most liberal preoperative VA threshold was 20/28.5 or worse, whereas the most conservative threshold was worse than 20/60. The mean preoperative BCVA was 0.55 logarithm of the minimum angle of resolution (logMAR) (∼20/70), and the mean postoperative BCVA was 0.35 logMAR (∼20/45). Generally, VA improved relative to baseline, regardless of the preoperative VA threshold. The smallest improvement in VA was observed in a study where the pre-operative VA to consider surgery was liberal (20/30 or worse), whereas the greatest VA improvement was observed in a study that used a conservative preoperative VA threshold (worse than 20/60). CONCLUSIONS The greatest improvement in BCVA was observed in studies where a conservative pre-operative VA threshold was used. The decision to operate should involve a patient-centered approach with a thorough discussion of the risks and benefits of PPV, regardless of the preoperative VA threshold used.

Abstract
PURPOSE To compare the efficacy and safety of pars plana vitrectomy with and without internal limiting membrane (ILM) peeling for macular hole (MH). METHODS A systematic literature search on Ovid MEDLINE, Embase, Cochrane Library, and Google Scholar was performed from January 2000 to 2023. The primary outcome was the final best-corrected visual acuity (BCVA). Secondary outcomes included MH closure rates and the need for repeat surgery. The authors performed a random-effects meta-analysis on Review Manager 5.4. RESULTS Fourteen studies on 880 eyes were included. Pars plana vitrectomy with and without ILM peel achieved a similar final BCVA ( P = 0.66). However, pars plana vitrectomy without ILM peeling achieved a significantly better final BCVA in eyes with closed MHs (WMD = 0.05 logMAR, 95% CI, 0.01-0.10, P = 0.02). Pars plana vitrectomy with ILM peeling achieved a significantly higher primary MH closure rate (RR = 1.21, 95% CI, 1.04-1.42, P = 0.02) and lower incidence of MH reoperation (RR = 0.19, 95% CI, 0.11-0.33, P < 0.001). The final MH closure rate ( P = 0.12) and incidence of MH recurrence ( P = 0.25) were similar between groups. CONCLUSION Pars plana vitrectomy with and without ILM peel achieved a similar final BCVA. However, pars plana vitrectomy without ILM peeling achieved a better final BCVA in eyes with closed MHs. ILM peeling achieved a greater primary MH closure rate and reduced need for reoperation.

Abstract
PURPOSE ChatGPT-4 is an upgraded version of an artificial intelligence chatbot. The performance of ChatGPT-4 on the United States Medical Licensing Examination (USMLE) has not been independently characterized. We aimed to assess the performance of ChatGPT-4 at responding to USMLE Step 1, Step 2CK, and Step 3 practice questions. METHOD Practice multiple-choice questions for the USMLE Step 1, Step 2CK, and Step 3 were compiled. Of 376 available questions, 319 (85%) were analyzed by ChatGPT-4 on March 21st, 2023. Our primary outcome was the performance of ChatGPT-4 for the practice USMLE Step 1, Step 2CK, and Step 3 examinations, measured as the proportion of multiple-choice questions answered correctly. Our secondary outcomes were the mean length of questions and responses provided by ChatGPT-4. RESULTS ChatGPT-4 responded to 319 text-based multiple-choice questions from USMLE practice test material. ChatGPT-4 answered 82 of 93 (88%) questions correctly on USMLE Step 1, 91 of 106 (86%) on Step 2CK, and 108 of 120 (90%) on Step 3. ChatGPT-4 provided explanations for all questions. ChatGPT-4 spent 30.8 ± 11.8 s on average responding to practice questions for USMLE Step 1, 23.0 ± 9.4 s per question for Step 2CK, and 23.1 ± 8.3 s per question for Step 3. The mean length of practice USMLE multiple-choice questions that were answered correctly and incorrectly by ChatGPT-4 was similar (difference = 17.48 characters, SE = 59.75, 95%CI = [-100.09,135.04], t = 0.29, p = 0.77). The mean length of ChatGPT-4's correct responses to practice questions was significantly shorter than the mean length of incorrect responses (difference = 79.58 characters, SE = 35.42, 95%CI = [9.89,149.28], t = 2.25, p = 0.03). CONCLUSIONS ChatGPT-4 answered a remarkably high proportion of practice questions correctly for USMLE examinations. ChatGPT-4 performed substantially better at USMLE practice questions than previous models of the same AI chatbot.

Abstract
PURPOSE To investigate the association between social determinants of health (SDH) in the domains of social and community context, education access, environmental context, economic stability, and healthcare access, with glaucoma prevalence. DESIGN Cross-sectional study. METHODS The study population consisted of adult participants who answered glaucoma-related questions on the 2017 National Health Interview Survey (NHIS), the most recent iteration that includes glaucoma-related questions. The main outcome measures included the relationships between SDH-related factors and self-reported glaucoma diagnosis as well as self-reported glaucomatous vision loss were examined using univariable and multivariable regression models. RESULTS In total, 26,696 of 26,742 (99.83%) NHIS respondents were included, of whom 880 (3.30%) reported a glaucoma diagnosis and 275 (1.03%) reported glaucomatous vision loss. Participants were predominantly middle-aged (50.95 ± 18.60 years), female (54.75%), and non-Hispanic White (70.49%). In age-adjusted multivariable regression (n = 25,456), non-Hispanic Black race (odds ratio [OR] = 1.87, 99% CI = [1.37, 2.55], P < .001, compared to non-Hispanic White race) and poor health status (OR = 1.54, 99% CI = [1.00, 2.37], P = .01, compared to good health status) were significant predictors of glaucoma diagnosis. For glaucomatous vision loss, having an income below the poverty threshold (OR = 2.41, 99% CI = [1.12, 5.20], P = .003, compared to income ≥5 times the poverty threshold) was the only significant predictor in univariable analyses. No SDH-related factors were significantly associated with glaucomatous vision loss in multivariable analysis (n = 848). Multicollinearity was minimal (variation inflation factor<1.6 for all independent variables). CONCLUSIONS Non-Hispanic Black race and poor health status were associated with self-reported glaucoma diagnosis. Physicians and policymakers may consider SDH when assessing clinical risk and designing public health interventions.

Abstract
PURPOSE To validate the quantitative assessment of metamorphopsia in rhegmatogenous retinal detachment(RRD) using M-CHARTS by determining its correlation with subjective reporting of metamorphopsia with a validated metamorphopsia questionnaire(modified MeMoQ). METHODS Research Ethics Board approved, prospective observational study carried out at St. Michael's Hospital, Toronto, Canada. Patients with primary, unilateral RRD and healthy controls were included. Metamorphopsia at 3-months was assessed with modified MeMoQ and M-CHARTS. RESULTS 100 patients(50 with RRD,50 controls) were included. 70%(35/50) of the RRD group had metamorphopsia with M-CHARTS and 80%(40/50) with MeMoQ. The modified MeMoQ and total M-CHARTS scores were significantly higher in patients with RRD compared to controls(p<0.0001). Cronbach's alpha reliability coefficient was 0.934 in the RRD group. Horizontal, vertical, and total M-CHARTS scores were significantly correlated with MeMoQ scores(rs=0.465,p=0.0007;rs=0.405,p=0.004;rs=0.475,p=0.0005,respectively). M-CHARTS was 72.7% sensitive and 94.6% specific for detection of metamorphopsia(positive score≥0.2), with an area under the ROC curve=0.801. A stronger correlation was found in patients who scored ≥0.2 on the M-CHARTS and reported metamorphopsia with the MeMoQ(rs=0.454,p=0.001). CONCLUSION We have validated M-CHARTS as a tool to quantitatively assess metamorphopsia in patients with RRD, which is significantly correlated with patient-reported outcomes using the metamorphopsia questionnaire(MeMoQ). A total score of ≥0.2 with M-CHARTS was more strongly correlated with MeMoQ.

Abstract
In this meta-analysis, we aim to compare the efficacy and safety of pars plana vitrectomy (PPV) versus tap-and-inject (TAI) of intravitreal antibiotics for the management of endophthalmitis secondary to intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents. A systematic literature search was conducted on Ovid MEDLINE, EMBASE, and Cochrane Central (January 2005-October 2022). The primary analysis compared initial PPV versus TAI and the secondary analysis examined the efficacy and safety of TAI alone compared to TAI followed by PPV. The quality of non-randomized observational studies was assessed using the Newcastle-Ottawa Scale. The quality of the evidence was assessed for each outcome. A random effects meta-analysis was performed. Weighted mean differences (WMDs) with 95% confidence intervals were reported. Of the 7474 screened studies, nine studies reporting on 153 eyes were included. The change in mean best corrected visual acuity (BCVA) between endophthalmitis presentation and last follow-up did not significantly differ between the initial TAI versus PPV groups (WMD = 0.05 units; 95% CI -0.12 to 0.22; p = 0.59; heterogeneity p = 0.41). The difference in pre- to post-treatment mean BCVA did not significantly differ between eyes that received TAI alone or TAI followed by PPV (WMD = 0.04 units; 95% CI -0.42 to 0.51; p = 0.85; heterogeneity p = 0.74). While the meta-analysis revealed no significant difference in the change in BCVA between PPV and TAI to treat endophthalmitis secondary to anti-VEGF agents, the quality of evidence was low with potential for confounding and selection bias. Further well-designed studies in this setting are needed.

Abstract
BACKGROUND The purpose of the study is to compare visual acuity, complications and outer retinal integrity following subretinal fluid (SRF) drainage from the peripheral retinal breaks (PRBs) versus posterior retinotomy (PR) versus perfluorocarbon liquid (PFCL) for macula-off rhegmatogenous retinal detachments (RRDs) at 2 years post-surgery. METHODS Retrospective analysis of 300 consecutive patients with primary RRD undergoing 23-gauge pars plana vitrectomy with SRF drainage through (1) PRB (n=100), (2) PR (n=100) or (3) with PFCL (n=100). Primary outcomes were visual acuity (best-corrected visual acuity (BCVA)) and complications (cystoid macular oedema (CMO) and epiretinal membrane (ERM)). Secondary outcomes were discontinuity of the external limiting membrane (ELM), ellipsoid zone (EZ) and interdigitation zone (IDZ) at 2 years post-surgery. RESULTS Mean (±SD) logMAR BCVA at 24 months was better in the PRB compared with PR and PFCL, with PFCL having the worst BCVA (PRB 0.5±0.6; PR 0.7±0.5; PFCL 0.9±0.7, p=0.001). CMO was higher with PFCL (PRB 29.7%; PR 30.2%; PFCL 45.9%, p=0.0015) and ERM formation was higher in PR (PRB 62.6%; PR 93.0%; PFCL 68.9%, p=0.002). There were no differences in ELM or EZ discontinuity. However, IDZ discontinuity was higher in PFCL (PRB 34%; PR 27%; PFCL 46%, p=0.002) at 2 years. CONCLUSIONS Visual acuity was worse and discontinuity of the IDZ and CMO was greater in eyes with PFCL-assisted drainage compared with PRB or PR. Drainage technique may impact long-term visual acuity and photoreceptor integrity.

Abstract
PURPOSE To compare the risk of systemic arteriovenous thrombotic events between intravitreal anti-vascular endothelial growth factor (anti-VEGF) and sham injections. DESIGN Random-effects meta-analysis. METHODS A systematic search was performed on OVID MEDLINE, Embase, and Cochrane Library from January 2005 to August 2023. Our inclusion criteria were randomized controlled trials (RCTs) reporting on systemic arteriovenous events for standard dose intravitreal anti-VEGF agents for any indication. RESULTS A total of 20 RCTs reporting on 12,833 eyes were included. There was no significant difference in the risk of any thrombotic event between bevacizumab 1.25 mg and ranibizumab 0.5 mg (Risk ratio (RR) = 0.96, 95% CI = 0.52-1.75, P = .89). There was no significant difference between bevacizumab and ranibizumab when restricting to arterial thrombotic events (RR= 0.88, 95% CI = 0.60-1.30, P = .53) or venous thrombotic events (RR = 1.99, 95% CI =86 0.68-5.82], P = .21). The risk of arterial thrombotic events was similar between aflibercept and bevacizumab (RR = 1.11, 95% CI = 0.60-2.07, P = .74), between aflibercept and ranibizumab (RR= 0.77, 95% CI = 0.49-1.21, P = .26), between brolucizumab and aflibercept (RR= 0.67, 95% CI = 0.32-1.38, P = .27), and between aflibercept and faricimab (RR = 0.96, 95% CI = 0.43-2.17, P = .93). Compared to sham, neither dose of ranibizumab (0.5 mg or 0.3 mg) showed a higher risk of arterial thrombotic events. CONCLUSIONS There was a similar risk of systemic arteriovenous thrombotic adverse events between anti-VEGF agents and between ranibizumab and sham injections.

Abstract
PURPOSE To evaluate the association of baseline morphologic stage of rhegmatogenous retinal detachment (RRD) using OCT with postoperative anatomic and visual acuity (VA) outcomes. DESIGN Retrospective cohort study. SUBJECTS Consecutive primary fovea-involving RRDs referred from January 2012 to September 2022. METHODS Patients with primary RRD and no prior macular pathology with gradable baseline OCT were assessed. Best-corrected VA (BCVA) was assessed at presentation and at 3, 6, and 12 months postoperatively. OCT scans were graded for parafoveal morphologic stage of RRD and foveal photoreceptor integrity. MAIN OUTCOME MEASURES Association of morphologic stage of RRD with 12-month BCVA. RESULTS Three hundred fifty-one patients were included. Sixty-eight percent (238/351) were male, the mean (standard deviation) age was 61.2 (± 12.8) years, and 59% (206/351) were phakic. Thirteen percent (47/351) presented in stages 1 and 2, 15% (54/351) in stage 3a, 36% (126/351) in stage 3b, 24% (83/351) in stage 4, and 12% (41/351) in stage 5. Increasing stage was associated with worse foveal photoreceptor integrity, reduced baseline BCVA and longer duration of central vision loss (P < 0.001). Mean (standard deviation) 12-month BCVA by stage was 0.77 (± 0.64) for stages 1 and 2, 1.00 (± 0.53) for stage 3a, 1.36 (± 0.55) for stage 3b, 1.33 (± 0.66) for stage 4 and 1.55 (± 0.47) for stage 5. Increasing stage was associated with reduced postoperative BCVA (P < 0.001) at all time points after adjusting for covariates. A subgroup analysis of acute detachments with retinal pigment epithelium-photoreceptor dysregulation demonstrated no difference in postoperative BCVA between stages 1, 2, and 3a. However, 12-month BCVA was significantly better in stages 1, 2, and 3a vs. stage 3b (P = 0.002) and stage 3a vs. 3b (P = 0.008). CONCLUSIONS This study validates the clinical relevance of a recently proposed OCT-based staging system for outer retinal morphologic changes over time in RRD. Postoperative BCVA was significantly reduced in patients with worse presenting stage at all time points. In acute RRDs, 12-month BCVA was significantly better in stages 1, 2, and 3a vs. stage 3b, which suggests early stages may have better retinal recovery compared with stage 3b or worse. Stage 3b may represent a critical point where substantial structural changes occur, leading to worse outcomes in acute RRDs. Patients presenting with fovea-involving RRDs in stages 1, 2, or 3a may benefit from more urgent intervention.

Abstract
INTRODUCTION To determine whether the two popular artificial intelligence (AI) chatbots, ChatGPT and Bard, provide high-quality information concerning procedure description, risks, benefits, and alternatives of various ophthalmological surgeries. METHODS ChatGPT and Bard were prompted with questions pertaining to the description, potential risks, benefits, alternatives, and implications of not proceeding with various surgeries in different subspecialties of ophthalmology. Six common ophthalmic procedures were included in our analysis. Two comprehensive ophthalmologists and one sub-specialist graded each response independently using a five-point Likert scale. RESULTS Likert grading for accuracy was significantly higher for ChatGPT in comparison to Bard (4.5±0.6 vs 3.8±0.8, p<0.0001). Generally, ChatGPT performed better than Bard even when questions were stratified by type of ophthalmological surgery. There was no significant difference between ChatGPT and Bard for response length (2104.7±271.4 characters vs 2441.0±633.9 characters, p=0.12). ChatGPT responded significantly slower than Bard (46.0±3.0 seconds vs 6.6±1.2 seconds, p<0.0001). CONCLUSIONS Both ChatGPT and Bard may offer accessible and high-quality information relevant to the informed consent process for various ophthalmic procedures. Nonetheless, both AI chatbots overlooked probability of adverse events, hence limiting their potential and introducing patients to information that may be difficult to interpret.

Abstract
PURPOSE To determine sociodemographic predictors of poor vision in children and adolescents less than 18 years of age in a large, nationally representative sample of the US population. DESIGN Retrospective, population-based cross-sectional study. METHODS Using data from the 2021 National Health Interview Survey (NHIS), participants less than 18 years of age for whom data were available on vision difficulty were included in our analysis. Our primary outcome was vision difficulty. Sociodemographic variables were investigated as predictors of vision difficulty. Logistic regression models were performed using Stata version 17.0. An odds ratio (OR) and 95% CI were reported for analyses. RESULTS The 2021 NHIS reported on 8261 children and adolescents, of whom 7373 had data pertaining to vision difficulty and were included in our sample. Vision difficulty was associated with being unable to afford medical care (OR = 2.60, 95% CI = 1.17, 5.80, P = 0.02) and having public health insurance (OR = 1.52, 95% CI = 1.09, 2.12, P = .01). Compared to children less than 5 years of age, children ranging from 5 to 8 years (OR = 4.29, 95% CI = 2.26, 8.15, P < .01) and adolescents ranging from 16 to 17 years (OR = 6.06, 95% CI = 3.17, 11.58, P < .01) had a higher odds of vision difficulty. Compared to participants for whom the highest level of education of adults in their family was grade 1 to 11, the odds of vision difficulty were lower in those whose parents had a professional school or doctoral degree (OR = 0.30, 95% CI = 0.11, 0.84, P = .02). CONCLUSIONS Multiple sociodemographic factors are associated with vision difficulty in young persons. In working toward achieving equity in vision health, it is imperative that disparities mediated by sociodemographic factors be addressed through public health policies.

Abstract
Although there have been numerous innovations in the management of retinal detachment (RD) over the past decades, there is still limited understanding of the pathophysiological processes that take place before and after repair. Summarizing key concepts using animal studies may allow for a better assessment of common pre- and postoperative microstructural abnormalities in RD. We performed a systematic literature review on Ovid MEDLINE, EMBASE, and Cochrane Controlled Register of Trials from January 1968 to January 2022, searching animal or human studies reporting retinal histologic changes following primary or induced RD. Thirty-two studies were included. Main cellular events were summarized: photoceptor apoptosis occurs as early as 12 hours after RD and, although most cells survive, there is extensive remodeling. Outer segments progressively degenerate, while inner segments are reorganized. Rod and cone opsins are redistributed, and rod axons retract while cones undergo changes in shape. Second- and third-order neurons rearrange their dendritic processes, and Müller cells become hypertrophic, growing into the subretinal space. Finally, retinal pigment epithelium cells undergo a change in their morphology. Acknowledging critical morphologic changes following RD is crucial in understanding why anatomical and functional outcomes can vary. Insights from histological studies, together with high-resolution imaging, may be key in identifying novel biomarkers in RD.

Abstract
PURPOSE To investigate hyperreflective dots (HRDs) on baseline OCT in rhegmatogenous retinal detachment (RRD). DESIGN Retrospective cohort study. SUBJECTS Consecutive primary fovea-off RRDs presenting between January 2012 and September 2022. METHODS Visual acuity (VA) was obtained at baseline, 3, 6, and 12 months. Baseline foveal OCT scans were graded for the presence of HRDs in the outer retina, morphologic stage of RRD in the parafovea, and foveal photoreceptor integrity (intact, patchy or complete loss of the bacillary layer). Epiretinal membrane (ERM) and cystoid macular edema (CME) were graded after surgery. MAIN OUTCOME MEASURES The primary outcome was the proportion of patients in each morphologic stage with HRDs present on OCT and their association with postoperative VA. Secondary outcomes included association with the height of foveal detachment, duration of central vision loss, RRD extent, and development of ERM/CME. RESULTS A total of 351 patients were included. The presence of HRDs by morphologic stage of RRD was 0% in stage 1, 4.5% (2/42) in stage 2, 13% (7/54) in stage 3a, 16% (20/126) in stage 3b, 48% (40/83) in stage 4, and 85% (35/41) in stage 5. Hyperreflective dots were associated with increasing stage of RRD (P < 0.001), reduced integrity of foveal photoreceptors (P < 0.001), and reduced postoperative VA at 3, 6, and 12 months (P < 0.001), after excluding visually significant cataracts and adjusting for covariates. There was also a significant association between HRDs and height of foveal detachment, duration of central vision loss, and RRD extent (P < 0.001). Hyperreflective dots were neither associated with postoperative ERM formation nor with its severity (P = 0.27). Nevertheless, they were associated with the occurrence of CME at 3 and 6 months after surgery (P = 0.01; P = 0.006). CONCLUSIONS Hyperreflective dots have been hypothesized to consist of intraretinal inflammatory cells. We found that HRDs were significantly associated with the morphologic stage, extent, duration, and height of the RRD before surgery and with reduced VA and CME after surgery. Our results suggest that HRDs are associated with photoreceptor degeneration, as longstanding and extensive RRDs are more likely to present with HRDs. The association of HRDs with CME provides insight into the possible importance of inflammatory processes in RRD before and after surgery.

Abstract
PURPOSE To assess clinical outcomes in elderly patients aged ≥ 75 years who underwent pneumatic retinopexy (PnR) for primary rhegmatogenous retinal detachment (RRD). DESIGN Retrospective cohort study. SUBJECTS Patients aged ≥ 75 years with primary RRD undergoing PnR. METHODS This study evaluates clinical outcomes among eligible patients who presented from October 1, 2010, to December 31, 2022, with a minimum of 3 months' follow-up. There were no limitations with respect to the number, size, or location of retinal breaks. Exclusion criteria included significant proliferative vitreoretinopathy or previous retinal detachment repair in the index eye, inability to maintain the postoperative posturing requirements or inability to carry out adequate examination of the peripheral retina because of media opacity. Lens status did not impact the decision to offer PnR. MAIN OUTCOME MEASURES Pneumatic retinopexy primary anatomic reattachment rate and postoperative best corrected visual acuity (BCVA) at 3 months. RESULTS Eighty patients with a mean age of 80.6 ± 4.6 years were included in this study; 35% (28/80) were phakic and 34% (27/80) presented with a fovea-on RRD. The mean number of breaks in the detached retina was 1.52 ± 1.13, and the mean number of quadrants of detached retina was 2.35 ± 0.93. The primary anatomic reattachment rate at 3 months after PnR was 78.8% (63/80), whereas the remaining 21.2% (17/80) failed PnR and underwent an operating room procedure. There was a statistically significant improvement in logarithm of the minimum angle of resolution (logMAR) BCVA from baseline to 3 months (1.29 ± 0.94 and 0.69 ± 0.67, respectively, P < 0.001). A subgroup analysis that only included patients aged > 80 years was also performed, with a total of 39 patients with a mean age of 84.4 ± 3.5 years. The primary anatomic reattachment rate with PnR in this subgroup was 74.4% (29/39), with a statistically significant improvement in BCVA from baseline to 3 months (1.4 ± 1.05 and 0.77 ± 0.70, respectively; P = 0.004). CONCLUSIONS Elderly patients treated with PnR for primary RRD had relatively comparable primary anatomic reattachment rates with other surgical techniques such as pars plana vitrectomy and scleral buckle. Pneumatic retinopexy is an effective, minimally invasive office-based procedure that may be desirable for some elderly patients.

Abstract
PURPOSE To assess the incidence of persistent subfoveal fluid (PSFF) in pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) following rhegmatogenous retinal detachment (RRD) repair and to determine its association with functional outcomes. METHODS Posthoc analysis of the PIVOT randomised trial. Eyes with gradable en face and cross-sectional spectral-domain optical coherence tomography (SD-OCT) scans at 1-2 months postoperatively were included. Primary outcome was the proportion of patients with PSFF following PnR versus PPV at 1-2 months postoperatively. Secondary outcomes included association of PSFF with Early Treatment Diabetic Retinopathy Study (ETDRS) letter score at 3, 6 and 12 months and metamorphopsia score (MCHARTs) at 12 months. RESULTS Of 176 participants enrolled in PIVOT, 158 (89.8%) had gradable SD-OCT scans. Intergrader agreement was 0.870 (Cohen's kappa). The incidence of PSFF was 16% (13/81) following PnR and 10.4% (8/77) following PPV (p=0.298; OR=1.65, 95% CI 0.64 to 4.23). Median ETDRS score at 3 months postoperatively between eyes with and without PSFF was 71 (IQR=58-78) and 78 (IQR=70-84), respectively (difference=7 letters, p=0.037), with no significant difference at subsequent 6-month and 12-month visits. Median metamorphopsia scores in patients with versus without PSFF were: horizontal: 0.1 (IQR=0-0.3) vs 0 (IQR=0-0.2) (difference=0.1, p=0.228) and vertical: 0.25 (IQR=0-0.4) vs 0 (IQR=0-0.2) (difference=0.25, p=0.148), respectively. CONCLUSIONS There was no significant difference in the incidence of PSFF in eyes undergoing PnR versus PPV for RRD. The presence of PSFF at 1-2 months postoperatively was associated with worse ETDRS letter score at 3 months, but there was no difference at 1 year. TRIAL REGISTRATION NUMBER NCT01639209.

Abstract
PURPOSE To investigate the relationship between social determinants of health with self-reported vision difficulty. DESIGN Cross-sectional, population-based analysis. METHODS The National Health Interview Survey (NHIS) is an annual survey based on the U.S. population ≥18 years of age. It provides self-reported data on demographic characteristics, socioeconomic factors, health status, and health care access. The 2021 NHIS database was used in this study. Adult participants of the NHIS who responded to the vision difficulty question "Do you have difficulty seeing, even when wearing glasses or contact lenses?" were included in this analysis. The outcome of interest was self-reported vision difficulty by participants. Analysis was done through univariable and multivariable logistic regression. RESULTS Overall, there were 29,464 participants included in the analysis. Univariable logistic regression showed an increased odds of self-reported vision difficulty among female (odds ratio [OR] 1.28 [95% confidence interval {CI} 1.20-1.38]; P < .001), gay, lesbian, or bisexual participants (OR 1.24 [95% CI 1.04-1.49]; P = .02), those who possessed public compared with private insurance (OR 1.83 [95% CI 1.69-1.99]; P < .001), those with less than a high school education (OR 1.88 [95% CI 1.67-2.13]; P < .001), and those with an income below the poverty threshold (OR 2.22 [95% CI 1.96-2.51]; P < .001). Multivariable analysis revealed an increased risk of vision difficulty reported amongst non-Hispanic Black participants (OR 1.65 [95% CI 1.21-2.25]; P = .002). CONCLUSIONS A multitude of sociodemographic factors are associated with self-reported vision difficulty in the U.S. POPULATION Our findings emphasize the importance of considering factors of social determinants of health in clinical practice and policymaking for patients with vision loss.

Abstract
BACKGROUND The safety and effectiveness of pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling remains poorly understood for the treatment of epiretinal membrane (ERM). OBJECTIVES Our study aims to compare the safety and effectiveness of PPV with and without ILM peeling for ERM. METHODS A systematic literature search was conducted on Ovid MEDLINE, Embase, Cochrane Library, and Google Scholar from January 2000 to January 2023 for comparative studies reporting visual and anatomical outcomes for patients with ERM that received PPV with or without ILM peeling. Primary outcomes included best-corrected visual acuity (BCVA) at last study observation and change in BCVA from baseline. Secondary outcomes included retinal thickness (RT) at last study observation, change in RT from baseline, risk of ERM recurrence, and adverse events. A random-effects meta-analysis was performed. Risk of bias of randomized controlled trials was assessed using the Risk of Bias 2 tool of observational studies using the Risk of Bias in Non-randomized Studies of Interventions-I tool. The certainty of evidence of outcomes was evaluated using Grading of Recommendations, Assessment, Development and Evaluation criteria. RESULTS Nineteen studies reporting on 1,291 eyes at baseline were included. PPV with and without ILM peel achieved a similar BCVA at last study observation (p = 0.68) and change in BCVA from baseline (p = 0.79). These findings remained consistent irrespective of whether simultaneous phacoemulsification was performed. PPV with ILM peel achieved a significantly lower incidence of ERM recurrence (risk ratio [RR] = 0.26, 95% CI = [0.13, 0.51], p < 0.0001) and additional surgery (RR = 0.17, 95% CI = [0.04, 0.74], p = 0.02) compared to PPV without ILM peel. CONCLUSION PPV with and without ILM peel achieved a similar BCVA at last study observation in ERM patients. Patients treated with PPV and ILM peel also had a reduced risk of ERM recurrence and lower reoperation risk. These conclusions are associated with a moderate certainty of evidence and potential for bias from multiple non-randomized studies.

Abstract
Purpose To describe the pathophysiology of secondary macular hole (MH) in rhegmatogenous retinal detachment (RRD). Methods A retrospective cohort of 360 consecutive primary fovea-off RRDs presenting to St. Michael's Hospital, Toronto, from January 2012 to September 2022 were included. Preoperative OCT was assessed for bacillary layer detachment (BALAD) abnormalities. Histological sections of normal eyes were assessed to inform OCT interpretations. Primary outcome measure was the progression of BALAD to full-thickness MH (FTMH). Results Of the 360 patients, 22.5% (n = 81) had BALAD abnormalities at presentation. Eight percent (29/360) had associated MH, of which 79.3% (23/29) were a BALAD-lamellar hole and 20.7% (6/29) were FTMH. After reattachment, 62% of MHs persisted (18/29), of which 83% (15/18) had BALAD-lamellar holes that subsequently progressed to FTMH in a mean of 8.1 ± 3.2 days. BALAD-lamellar holes had significantly worse postoperative visual acuity (P < 0.001) when compared with other BALAD abnormalities (58/81) or with the rest of the cohort (279/360). OCT spectrum from BALAD to FTMH includes (1) cleavage planes extending from Henle fiber layer into the BALAD; (2) central outer nuclear layer thinning; (3) Müller cell cone loss with tissue remnants at the foveal walls; (4) retinal tissue operculum close to BALAD-MH; and (5) progressive thinning or degradation of the posterior band of BALAD-lamellar hole leading to FTMH. Histological specimens identified foveal regions of low mechanical stability. Conclusions BALAD plays a crucial role in the pathophysiology of MH in RRDs, which forms owing to sequential changes in four critical areas: RPE-photoreceptor interface, myoid zone, Henle fiber layer, and Müller cell cone with surrounding tissue. Timely management of fovea-off RRD with BALAD may be prudent to avoid the progression to BALAD-lamellar hole, subsequent FTMH, and worse functional outcomes.

Abstract
Intravitreal injections of antiangiogenic agents are pivotal in treating neovascular age-related macular degeneration (nAMD). The comparative efficacy and safety of treat-and-extend (T&E) versus bimonthly, monthly, and pro re nata (PRN) dosing remains unclear. A systematic review and meta-analysis of English-language RCTs reporting on efficacy and/or safety outcomes of dosing regimens of anti-VEGF agents in nAMD was performed. Best-corrected visual acuity (BCVA, ETDRS letters) at last follow-up represented the primary endpoint, while central subfield thickness (CSFT, μm), injection burden, and ocular adverse events were secondary endpoints. A random effects meta-analysis was performed, and 95% confidence intervals were calculated. Across six RCTs, 781 T&E-, 663 monthly-, 130 PRN-, and 123 bimonthly treated eyes were included. Mean changes in BCVA and CSFT at last follow-up were similar between T&E versus monthly (WMD, -0.62 letters; 95% CI, -2.12 to 0.87; P = 0.41; WMD, 5.30 microns; 95% CI, -10.67 to 21.26; P = 0.52, respectively), bimonthly (WMD, 1.68 letters; 95% CI, -3.55 to 6.91; P = 0.53; WMD, -18.91 microns; 95% CI, -46.41 to 8.60; P = 0.18, respectively), and PRN (BCVA WMD, 1.08 letters; 95% CI, -2.95 to 5.11; P = 0.60) regimens. T&E was associated with a reduced injection burden versus monthly (WMD, -4.52 injections; 95% CI, -6.66 to 2.39; P < 0.001) but higher injection burden versus PRN (WMD, 1.81 injections; 95% CI, 1.12 to 2.51; P < 0.001) dosing. There was no significant difference in safety outcomes amongst comparators. There was no significant difference in efficacy and safety between T&E, bimonthly, monthly, and PRN dosing. T&E resulted in fewer injections versus monthly and fewer clinic visits versus PRN.

Abstract
Importance In-office suprachoroidal viscopexy (SCVEXY) is a minimally invasive technique for rhegmatogenous retinal detachment (RRD) repair that can be performed with no incision, no tamponade agent, and no positioning requirements. This technique has the potential to be a step forward in the armamentarium to treat RRDs. Objective To describe in-office SCVEXY for RRD repair. Design, Setting, and Participant In this single-case report with short follow-up, a man in his 50s with pseudophakia and recent visual loss presented to St Michael's Hospital, Unity Health Toronto, with a fovea-off RRD in the right eye, extending from 6 to 10 o'clock, with no visible causative retinal break. Exposure Injection of suprachoroidal sodium hyaluronate, 1%, in the region of the suspected break, using a 30-gauge needle with a custom-made guard that exposed only 1 mm of the needle. Main Outcome and Measures Ability to perform in-office SCVEXY and to obtain a visible choroidal indentation. Results After the procedure, a dome-shaped choroidal convexity was present in the superior temporal area. The patient achieved macular reattachment in less than 24 hours with no postoperative abnormalities, such as outer retinal folds, residual subfoveal fluid, or retinal displacement, with rapid recovery of the outer retinal bands on optical coherence tomography. The optical coherence tomography scans acquired in the area of the choroidal convexity demonstrated the location of the viscoelastic material in the suprachoroidal space. Laser retinopexy was applied in the suspected region of the retinal tear, and the patient was able to resume normal activity immediately after the procedure with no restrictions. Conclusions and Relevance Suprachoroidal viscopexy is feasible as an in-office technique to create a temporary choroidal buckle for RRD repair. It is a minimally invasive procedure with the potential to maximize anatomical outcomes of integrity and postoperative functional outcomes in RRD because its mechanism of action does not require drainage of subretinal fluid or intraocular gas tamponade. Nevertheless, this was a single-case report with short follow-up, which limits the ability to determine the procedure's benefits, potential adverse events, failure rates, and best-case selection. Further work is required to refine the procedure and assess its efficacy and safety.

Abstract
PURPOSE To comprehensively examine the cost effectiveness, reattachment rate, and complications of pneumatic retinopexy (PnR) compared with pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) within a universal health care system. DESIGN Population-based, multicenter, consecutive, retrospective longitudinal cohort analysis. SUBJECTS We identified consecutive adults aged ≥ 50 years requiring surgery for primary RRD over a 20-year interval between April 1, 2002, and March 31, 2022. Initial surgery was considered the index date for analyses. INTERVENTION Pneumatic retinopexy was compared with PPV in all analyses. MAIN OUTCOME MEASURES The primary analysis investigated the mean annualized health care costs comparing PnR to PPV over the 2 years after initial surgery. Secondary analyses examined the primary reattachment rate and complications. RESULTS In total, 25 665 eligible patients were identified, with 8794 undergoing PnR and 16 871 undergoing PPV. The mean patient age was 65 years and 39% were women. The mean annualized cost after PnR was $8924 and $11 937 after PPV (mean difference, $3013; 95% confidence interval, $2533-$3493; P < 0.001). The primary reattachment rate at 90 days after PnR was 83% and after PPV was 93% (P < 0.001). The risk of cataract or glaucoma surgery was lower after PnR, and the frequency of ophthalmology clinic visits, intravitreal injections, and anxiety was higher after PnR. Hospitalizations and long-term disability were less frequent after PnR. CONCLUSIONS Pneumatic retinopexy, when compared with PPV, was associated with lower long-term health care costs. Pneumatic retinopexy appeared to be effective, safe, and inexpensive, thus offering a viable option for improving access to RRD repair in appropriately selected cases.

Abstract
BACKGROUND/AIM To assess the utility of single-capture ultra-widefield confocal scanning laser ophthalmoscope with integrated swept-source optical coherence tomography (UWF-SS-OCT) in the management of rhegmatogenous retinal detachment (RRD) and associated peripheral pathology. METHODS 138 eyes of 101 consecutive patients with RRD and/or associated peripheral pathology at a vitreoretinal practice in Toronto, Canada between December 2020 and February 2021 that had UWF-SS-OCT with interpretable scans were included. A 200 degree fundus photograph was used to navigate a built-in 100 kHz UWF-SS-OCT to image pathology with a high-density 23 mm line scan and/or volume scan. Main outcomes were the microstructural details of the RRD and/or associated peripheral pathology and longitudinal assessment of response to laser retinopexy and cryopexy with UWF-SS-OCT. RESULTS 56.5% (78/138) of eyes had prior or current RRD (6 eyes had combined retinoschisis detachment), 31.1% (43/138) had retinal tears/holes and 14.5% (20/138) had lattice degeneration. UWF-SS-OCT impacted management and was useful in determining the presence or absence of vitreoretinal traction with retinal holes or tears. It was also helpful in differentiating retinal detachment, schisis-detachment and retinoschisis in cases where it was not apparent clinically. There were also several novel findings such as vitreous adhesion at the posterior border of a retinal dialysis. UWF-SS-OCT was performed longitudinally before and immediately following laser retinopexy (n=22) and cryopexy (n=4). Microstructural changes were consistent with chorioretinal adhesion immediately following laser versus postprocedure day 6 following cryopexy. CONCLUSION Single-capture UWF-SS-OCT enabled novel insights in RRD and associated peripheral vitreoretinal pathology.

Abstract
There remains limited agreement regarding the efficacy and safety of different antivascular endothelial growth factor (anti-VEGF) agents for the management of polypoidal choroidal vasculopathy (PCV). Our meta-analysis compares different anti-VEGF agents for PCV treatment. Ovid MEDLINE, EMBASE, and Cochrane Library were systematically searched from January 2000 to July 2022. We included articles comparing the efficacy and safety of different anti-VEGF agents, specifically bevacizumab (BEV), ranibizumab (RAN), aflibercept AFL), and brolucizumab (BRO), for patients with PCV. 10,440 studies were identified, 122 underwent full-text review, and seven were included. One study was a randomized trial, and six were observational studies. Ranibizumab and aflibercept were associated with a similar best-corrected visual acuity (BCVA) at the last visit in three observational studies (P = 0.10), similar retinal thickness at the last visit in two observational studies (P = 0.85). One observational study comparing BEV versus RAN found comparable outcomes for final BCVA, retinal thickness, and polyp regression. One randomized trial on BRO versus AFL found comparable outcomes for improvement in BCVA, while anatomical outcomes favored BRO. The available evidence suggests that final BCVA is comparable across different anti-VEGF agents, however, further investigation is warranted due to paucity of evidence.

Abstract
PURPOSE To assess the risk of retinal displacement after scleral buckle (SB) versus pars plana vitrectomy with SB (PPV-SB). DESIGN Multicenter prospective nonrandomized clinical trial. METHODS The study took place at VitreoRetinal Surgery in Minneapolis, Minnesota, Sankara Nethralaya in Chennai, India, and St. Michael's Hospital in Toronto, Canada from July 2019 to February 2022. Patients who underwent successful SB or PPV-SB for fovea-involving rhegmatogenous retinal detachment with gradable postoperative fundus autofluorescence (FAF) imaging were included in the final analysis. Two masked graders assessed FAF images 3 months postoperatively. Metamorphopsia and aniseikonia were assessed with M-CHARTs and the New Aniseikonia Test, respectively. The primary outcome was the proportion of patients with retinal displacement detected with retinal vessel printings on FAF in SB versus PPV-SB. RESULTS Ninety-one eyes were included in this study, of which 46.2% (42 of 91) had SB and 53.8% (49 of 91) underwent PPV-SB. Three months postoperatively, 16.7% (7 of 42) in the SB group and 38.8% (19 of 49) in the PPV-SB group had evidence of retinal displacement (difference = 22.1%; odds ratio = 3.2; 95% confidence interval [CI], 1.2-8.6; P = 0.02) on FAF. The statistical significance of this association increased after adjustment for extent of retinal detachment, baseline logarithm of the minimum angle of resolution, lens status, and sex in a multivariate regression analysis (P = 0.01). Retinal displacement was detected in 22.5% (6 of 27) of patients in the SB group with external subretinal fluid drainage and 6.7% (1 of 15) of patients without external drainage (difference = 15.8%; odds ratio = 4.0; 95% CI, 0.4-36.9; P = 0.19). Mean vertical metamorphopsia, horizontal metamorphopsia (MH), and aniseikonia were similar between patients in the SB and PPV-SB groups. There was a trend to worse MH in patients with retinal displacement versus those without retinal displacement (P = 0.067). CONCLUSIONS Scleral buckle is associated with less retinal displacement compared with PPV-SB, indicating that traditional PPV techniques cause retinal displacement. There is a trend toward increased risk of retinal displacement in SB eyes that underwent external drainage compared with SB eyes without drainage, which is consistent with our understanding that the iatrogenic movement of subretinal fluid, such as that which occurs intraoperatively during external drainage with SB, may induce retinal stretch and displacement if the retina is then fixed in the stretched position. There was a trend to worse MH at 3 months in patients with retinal displacement.

Abstract
INTRODUCTION There are no guidelines on the optimal anti-vascular endothelial growth factor (anti-VEGF) monotherapy regimen for patients with polypoidal choroidal vasculopathy (PCV). In this study, we aimed to assess the comparative safety and efficacy of different treatment regimens of anti-VEGF monotherapy for PCV. METHODS We conducted a systematic literature search on Ovid MEDLINE, Embase, and Cochrane Library from January 2000 to May 2023 for comparative articles reporting on different treatment regimens of anti-VEGF agents in PCV. Our primary outcomes were the final best-corrected visual acuity (BCVA) and the change in BCVA from baseline. Secondary outcomes were the final retinal thickness (RT), the change in RT from baseline, the rate of polyp closure, and the incidence of adverse events. RESULTS A total of 10,440 studies were screened, and seven studies reporting on 636 eyes with PCV at baseline were included in this systematic review. One RCT of 53 eyes found a similar final BCVA, change in BCVA from baseline, final RT, and complete polyp closure rate between a treat-and-extend (T&E) regimen and a bimonthly fixed-dosing regimen of aflibercept. This trial also found superiority of T&E for change in RT from baseline. One observational study of 33 eyes found a similar BCVA at last study observation between a pro re nata (PRN) regimen and bimonthly fixed-dosing regimen of aflibercept. One observational study of 42 eyes found a similar change in BCVA from baseline and complete polyp closure rate between a PRN regimen and bimonthly fixed-dosing regimen of aflibercept. One RCT of 249 eyes found a similar change in BCVA and RT from baseline, as well as polyp closure, between a T&E regimen and fixed 12-week dosing regimen of conbercept. One observational study of 30 eyes found a superiority of T&E aflibercept for change in BCVA and risk of polyp recurrence, compared to a PRN regimen. CONCLUSION Overall, there is a paucity of evidence comparing various treatment regimens of anti-VEGF therapy in patients with PCV. This limited evidence suggests that current treatment regimens are similarly efficacious, though T&E aflibercept achieved superior outcomes when compared to bimonthly dosing or PRN in some individual studies. Further trials are needed to confirm or refute these findings.

Abstract
BACKGROUND The comparative safety and efficacy of different doses of intravitreal triamcinolone acetonide (IVTA) for diabetic macular edema (DME) and macular edema (ME) secondary to retinal vein occlusion (RVO) is unclear. OBJECTIVES This meta-analysis aimed to compare the safety and efficacy of different doses of IVTA in this setting. METHODS A systematic literature search for randomized clinical trials (RCTs) was conducted on Cochrane Library, Ovid MEDLINE, and EMBASE from January 2005 to May 2022. Studies that reported on patients with DME or ME secondary to RVO that received treatment with different doses of IVTA were included. A random-effects meta-analysis was performed. Cochrane's Risk of Bias Tool 2 was used to assess the risk of bias, and Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines were used to assess certainty of evidence. RESULTS Five RCTs reporting on 1,041 eyes at baseline were included in this meta-analysis. In eyes with ME secondary to RVO, high-dose (4 mg) IVTA achieved a significantly better change in best-corrected visual acuity (WMD = -4.75 ETDRS letters, 95% CI = [-7.73, -1.78], p = 0.002) and reduction in retinal thickness (WMD = -93.02 μm, 95% CI = [-153.23, -32.82], p = 0.002) at months 4-6 compared to low-dose (1-2 mg) IVTA. However, high-dose IVTA had a higher risk of intraocular pressure-related adverse events (RR = 2.99, 95% CI = [1.05, 8.50], p = 0.04) and cataract surgery (RR = 5.67, 95% CI = [3.09, 10.41], p < 0.00001) than low-dose IVTA in eyes with ME secondary to RVO. These efficacy and safety differences in high-dose and low-dose IVTA were not observed in DME eyes. CONCLUSIONS The RCT evidence in this setting is limited. High-dose IVTA achieved greater improvements in visual acuity and reductions in retinal thickness than low-dose IVTA at months 4-6. However, high-dose IVTA had a less favorable safety profile than low-dose IVTA. The significance of these outcomes was based on patients with ME secondary to RVO, but not DME.

Abstract
BACKGROUND Retinopathy of prematurity (ROP) is the most common cause of preventable blindness in preterm infants. First-line treatments include intravitreal bevacizumab (IVB) or laser photocoagulation (LPC). OBJECTIVES The aim of the study was to evaluate neurodevelopmental safety of IVB compared to LPC for ROP. METHODS MEDLINE, Embase, and Cochrane library were searched up to September 2022. Studies were included with at least 12-month follow-up of primary outcomes such as severe neurodevelopmental impairment (sNDI), cerebral palsy (CP), and hearing impairment (HI). Secondary outcomes were moderate-to-severe neurodevelopmental impairment (msNDI), Bayley Scores of Infant Development (BSID-III), and visual impairment. RESULTS 1,231 patients from 11 comparative studies were included. Quality of evidence was rated low for all outcomes. IVB was associated with a higher risk for sNDI (risk ratio [RR] = 1.25, 95% confidence interval [CI]: [1.01, 1.53], p = 0.04); and CP (RR = 1.40, CI: [1.08, 1.81], p = 0.01) compared to LPC. There was no significant difference between IVB and LPC for msNDI (RR = 1.15, CI: [0.98, 1.35], p = 0.08) and HI (RR = 1.43, CI: [0.86, 2.39], p = 0.17). BSID-III percentile scores were similar between IVB and LPC, with weighted mean differences of 1.51 [CI = -1.25, 4.27], 2.43 [CI = -1.36, 6.22], and 1.97 [CI = -1.06, 5.01] for cognitive, language, and motor domains, respectively (p > 0.05). CONCLUSION To our knowledge, this is the largest meta-analysis on neurodevelopmental outcomes and the first to rigorously examine IVB monotherapy in ROP treatment. Compared to LPC, there was a marginally increased risk for sNDI and CP with IVB but little or no difference in the risk of msNDI and HI. Further randomized studies are needed to strengthen these findings.

Abstract
Importance ChatGPT is an artificial intelligence (AI) chatbot that has significant societal implications. Training curricula using AI are being developed in medicine, and the performance of chatbots in ophthalmology has not been characterized. Objective To assess the performance of ChatGPT in answering practice questions for board certification in ophthalmology. Design, Setting, and Participants This cross-sectional study used a consecutive sample of text-based multiple-choice questions provided by the OphthoQuestions practice question bank for board certification examination preparation. Of 166 available multiple-choice questions, 125 (75%) were text-based. Exposures ChatGPT answered questions from January 9 to 16, 2023, and on February 17, 2023. Main Outcomes and Measures Our primary outcome was the number of board certification examination practice questions that ChatGPT answered correctly. Our secondary outcomes were the proportion of questions for which ChatGPT provided additional explanations, the mean length of questions and responses provided by ChatGPT, the performance of ChatGPT in answering questions without multiple-choice options, and changes in performance over time. Results In January 2023, ChatGPT correctly answered 58 of 125 questions (46%). ChatGPT's performance was the best in the category general medicine (11/14; 79%) and poorest in retina and vitreous (0%). The proportion of questions for which ChatGPT provided additional explanations was similar between questions answered correctly and incorrectly (difference, 5.82%; 95% CI, -11.0% to 22.0%; χ21 = 0.45; P = .51). The mean length of questions was similar between questions answered correctly and incorrectly (difference, 21.4 characters; SE, 36.8; 95% CI, -51.4 to 94.3; t = 0.58; df = 123; P = .22). The mean length of responses was similar between questions answered correctly and incorrectly (difference, -80.0 characters; SE, 65.4; 95% CI, -209.5 to 49.5; t = -1.22; df = 123; P = .22). ChatGPT selected the same multiple-choice response as the most common answer provided by ophthalmology trainees on OphthoQuestions 44% of the time. In February 2023, ChatGPT provided a correct response to 73 of 125 multiple-choice questions (58%) and 42 of 78 stand-alone questions (54%) without multiple-choice options. Conclusions and Relevance ChatGPT answered approximately half of questions correctly in the OphthoQuestions free trial for ophthalmic board certification preparation. Medical professionals and trainees should appreciate the advances of AI in medicine while acknowledging that ChatGPT as used in this investigation did not answer sufficient multiple-choice questions correctly for it to provide substantial assistance in preparing for board certification at this time.

Abstract
PURPOSE To compare foveal avascular zone (FAZ) geometric indices using optical coherence tomography angiography (OCTA) in pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). FAZ morphology was assessed as a possible imaging feature of retinal displacement. METHODS This ALIGN post hoc analysis included primary fovea-off RRDs that underwent successful PnR or PPV, and performed OCTA, and fundus autofluorescence at (FAF) 3 months postoperatively at St. Michael's Hospital, Toronto, Canada. FAZ area (mm 2 ), axial ratio, circularity, and roundness were measured, and FAF images were assessed for retinal displacement. RESULTS Seventy-two patients were included, 78% (56/72) were male mean age was 60 ± 9 years, and 60% (43/72) were phakic. Sixty-five percent (47/72) and 35% (25/72) underwent PnR and PPV, respectively. The mean baseline logarithm of the minimum angle of resolution visual acuity was 1.49 ± 0.76. FAZ circularity was lower after PPV (0.629 ± 0.120) versus PnR (0.703 ± 0.122); P = 0.016. Sixty-six patients had gradable FAF images. Retinal displacement was present in 29% (19/66), 84.2% (16/19) of which had displacement in the macula. FAZ circularity was lower in eyes with displacement in the macula (0.613 ± 0.110) versus those without displacement (0.700 ± 0.124); P = 0.015. There was a moderate negative correlation between 12-month aniseikonia and FAZ circularity(r = -0.262; P = 0.041). CONCLUSION FAZ circularity was lower after PPV and in eyes with retinal displacement in the macula. Circularity was negatively correlated with 12-month aniseikonia scores. FAZ circularity may be another imaging feature to consider postoperatively after RRD repair.
