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
INTRODUCTION To determine whether the two popular artificial intelligence chatbots, ChatGPT and Bard, can provide high-quality information concerning procedure description, risks, benefits, and alternatives of various ophthalmic 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 the authors' analysis. Two comprehensive ophthalmologists and one subspecialist graded each response independently using a 5-point Likert scale. RESULTS Likert grading for accuracy was significantly higher for ChatGPT in comparison with 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 the type of ophthalmic surgery. There was no significant difference between ChatGPT and Bard for response length (2,104.7 ± 271.4 characters vs. 2,441.0 ± 633.9 characters, P = 0.12). ChatGPT responded significantly slower than Bard (46.0 ± 3.0 vs. 6.6 ± 1.2 seconds, P < 0.0001). CONCLUSION Both ChatGPT and Bard may offer accessible and high-quality information relevant to the informed consent process for various ophthalmic procedures. Nonetheless, both artificial intelligence chatbots overlooked the probability of adverse events, hence limiting their potential and introducing patients to information that may be difficult to interpret.

Abstract
BACKGROUND Stereotactic ablative radiation therapy (SBRT) is an emerging treatment option for primary renal cell carcinoma (RCC), particularly in patients who are unsuitable for surgery. The aim of this review is to assess the effect of increasing the biologically equivalent dose (BED) via various radiation fractionation regimens on clinical outcomes. METHODS A literature search was conducted in PubMed (Medline), EMBASE, and the Cochrane Library for studies published up to October 2023. Studies reporting on patients with localized RCC receiving SBRT were included to determine its effectiveness on local control, progression-free survival, and overall survival. A random effects model was used to meta-regress clinical outcomes relative to the BED for each study and heterogeneity was assessed by I2. RESULTS A total of 724 patients with RCC from 22 studies were included, with a mean age of 72.7 years (range: 44.0-81.0). Local control was excellent with an estimate of 99 % (95 %CI: 97-100 %, I2 = 19 %), 98 % (95 %CI: 96-99 %, I2 = 8 %), and 94 % (95 %CI: 90-97 %, I2 = 11 %) at one year, two years, and five years respectively. No definitive association between increasing BED and local control, progression-free survival and overall survival was observed. No publication bias was observed. CONCLUSIONS A significant dose response relationship between oncological outcomes and was not identified, and excellent local control outcomes were observed at the full range of doses. Until new evidence points otherwise, we support current recommendations against routine dose escalation beyond 25-26 Gy in one fraction or 42-48 Gy in three fractions, and to consider de-escalation or compromising target coverage if required to achieve safe organ at risk doses.

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
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
BACKGROUND Multidisciplinary cancer conferences consist of regular meetings between diverse specialists working together to share clinical decision making in cancer care. The aim of this study was to systematically review and meta-analyze the effect of multidisciplinary cancer conference intervention on the overall survival of patients with cancer. METHODS A systematic literature search was conducted on Ovid MEDLINE, EMBASE, and the Cochrane Controlled Register of Trials for studies published up to July 2023. Studies reporting on the impact of multidisciplinary cancer conferences on patient overall survival were included. A standard random-effects model with the inverse variance-weighted approach was used to estimate the pooled hazard ratio of mortality (multidisciplinary cancer conference vs non-multidisciplinary cancer conference) across studies, and the heterogeneity was assessed by I2. Publication bias was examined using funnel plots and the Egger test. RESULTS A total of 134 287 patients with cancer from 59 studies were included in our analysis, with 48 467 managed by multidisciplinary cancer conferences and 85 820 in the control arm. Across all cancer types, patients managed by multidisciplinary cancer conferences had an increased overall survival compared with control patients (hazard ratio = 0.67, 95% confidence interval = 0.62 to 0.71, I2 = 84%). Median survival time was 30.2 months in the multidisciplinary cancer conference group and 19.0 months in the control group. In subgroup analysis, a positive effect of the multidisciplinary cancer conference intervention on overall survival was found in breast, colorectal, esophageal, hematologic, hepatocellular, lung, pancreatic, and head and neck cancer. CONCLUSIONS Overall, our meta-analysis found a significant positive effect of multidisciplinary cancer conferences compared with controls. Further studies are needed to establish nuanced guidelines when optimizing multidisciplinary cancer conference integration for treating diverse patient populations.

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
BACKGROUND Cleft lip and/or palate (CL/P) is one of the most common congenital anomalies worldwide. Although CL/P management may require a series of interventions, mortality resulting from CL/P alone is rare. This study aims to examine recent trends of CL/P mortality rates in the USA. METHODS A retrospective population-based study was conducted using official US birth and death certificate data from the Centers for Disease Control and Prevention from 2000 to 2019. Annual mortality rates per 1000 births with CL/P were calculated across sex and racial groups. Multivariable logistic regression models estimated the effects of sex and race on the risk of mortality with CL/P, and linear regression models were used to examine temporal changes in mortality rate across sex and race. RESULTS From 2000 to 2019, 1119 deaths occurred in patients with documented CL/P, for an overall incidence of 20.3 deaths per 1000 births with CL/P (95% CI 18.9 to 22.8). Of these, Patau syndrome was the listed cause of death in 167 cases (14.9%). Black individuals (OR 1.93, 95% CI 1.85 to 2.01), Hispanic (1.54, 1.49 to 1.58) and American Indian individuals (1.28, 1.20 to 1.35) were at a greater risk of CL/P mortality compared with white individuals. Additionally, females were also at a greater risk (1.35, 1.21 to 1.49). A significant upward trend in CL/P mortality was observed in Hispanic (r2=0.70, p<0.01) and American Indian individuals (r2=0.81, p<0.01) from 2000 to 2019. CONCLUSIONS Cleft birth and mortality surveillance is essential in healthcare and prevention planning. Future studies are required to understand the differences in CL/P mortality rates across various sociodemographic groups.

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
Background Children have been suggested to benefit from digit replantation due to a greater neurogenerative capacity. We aimed to conduct a systematic review on digit replantation in children to provide a comprehensive overview of survival rates and functional outcomes. Methods A systematic literature search was conducted on Ovid MEDLINE, Embase, and the Cochrane Controlled Register of Trials for studies published between 1980 and 2023. We included peer-reviewed studies reporting on digit survival rates in pediatric patients under the age of 18 years who underwent single or multiple digit replantations distal to the metacarpophalangeal joint. Preoperative, intraoperative, and postoperative outcomes were extracted, and pooled estimates were derived using univariable analysis. Results Twenty-two studies reporting on 761 patients and 814 digit replantations were included in our study. Most replantations occurred in the index (n = 74), Tamai zone I (n = 168), and from clean-cut injuries (n = 190). The mean survival rate was 76% (n = 618/814), with a mean range of motion at the distal interphalangeal joint ranging from 64 degrees to 90 degrees and two-point discrimination ranging from 3.8 mm to 6.4 mm. Compared with clean-cut injuries, digit replantations from avulsion [odds ratio (OR), 0.81; 95% confidence interval (CI), 0.74-0.89] or crush (OR, 0.71; 95% CI, 0.59-0.82) injuries were associated with a lower odds of survival. Digit replantations performed with two venous (OR, 1.43, 95% CI; 1.28-1.59) or arterial anastomoses (OR, 1.65; 95% CI, 1.48-1.81) were associated with a higher odds of survival. Conclusions Our systematic review suggests that digit replantation may be a viable option in children. Further research is required to explore functionality after digit replantation in diverse pediatric populations.

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
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
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
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
The association between residual retinal fluid and visual acuity for diabetic macular edema (DME) and macular edema (ME) secondary to retinal vein occlusion (RVO) is not well established. We conducted a systematic literature search for peer-reviewed articles reporting on visual acuity stratified by subretinal fluid (SRF), intraretinal fluid (IRF), or any retinal fluid at final follow-up after intravitreal anti-vascular endothelial growth factor therapy injection for treatment of DME or ME secondary to RVO. Two observational studies on ME secondary to RVO and one study for DME found no significant differences between eyes with and without residual retinal fluid for final BCVA. One randomized controlled trial (RCT) found that eyes with residual retinal fluid had significantly worse final best-corrected visual acuity in ME secondary to RVO, whereas another RCT found no significant difference for DME. There is a paucity of evidence examining the impact of residual retinal fluid on visual acuity in DME and ME secondary to RVO. The limited evidence suggests that aggressive fluid resolution is worthwhile. [Ophthalmic Surg Lasers Imaging Retina 2023;54:50-58.].

Abstract
BACKGROUND Intravitreal anti-vascular endothelial growth factor (anti-VEGF) and steroid treatment are both used for macular edema (ME) secondary to retinal vein occlusion (RVO), however a continual reevaluation of their comparative efficacy is required. OBJECTIVES This meta-analysis aimed to compare the efficacy and safety of intravitreal anti-VEGF agents and intravitreal steroids for the treatment of ME secondary to RVO. METHODS A systematic literature search was conducted on Ovid MEDLINE, EMBASE, and the Cochrane Controlled Register of Trials for studies published between January 2005 and November 2021. Randomized controlled trials (RCTs) reporting on patients with ME secondary to RVO who were treated with intravitreal steroids or anti-VEGF agents were included. A random effects meta-analysis was performed. RESULTS 879 eyes from 11 RCTs were included. At the last study observation, intravitreal anti-VEGF agents were associated with a significantly better best corrected visual acuity (WMD = -0.14 logMAR, 95% CI = [-0.19, -0.09], p < 0.00001) and lower retinal thickness (WMD = -38.01 µm, 95% CI = [-56.17, -19.85], p < 0.0001) relative to intravitreal steroids. Similar findings were found at 3-12 month time points. Intravitreal anti-VEGF agents were associated with a significantly lower incidence of IOP-related adverse events (RR = 0.28, 95% CI = [0.15, 0.51], p < 0.0001), cataract development/progression (RR = 0.22, 95% CI = [0.09, 0.49], p = 0.0003), and conjunctival hemorrhage (RR = 0.52, 95% CI = [0.32, 0.86], p = 0.01). CONCLUSIONS Our meta-analysis found superiority of intravitreal anti-VEGF agents relative to intravitreal steroids for the treatment of ME secondary to RVO with regards to visual acuity, anatomic outcomes, and safety endpoints.

Abstract
TOPIC It is unclear whether there are differences in safety and efficacy between pars plana vitrectomy (PPV) alone and PPV with a supplemental scleral buckle (SB; PPV-SB) for the treatment of rhegmatogenous retinal detachment. CLINICAL RELEVANCE This meta-analysis aimed to compare the safety and efficacy of these surgical procedures. METHODS In this meta-analysis, Ovid MEDLINE, Embase, and Cochrane Library were systematically searched (January 2000-June 2021). The primary outcome was the final best corrected visual acuity (BCVA), whereas the secondary outcomes were reattachment rates and complications. The risk of bias was assessed using the Cochrane risk-of-bias tool for randomized controlled trials (RCTs) and the risk of bias in nonrandomized studies of interventions tool for nonrandomized studies. RESULTS This study included 15 661 eyes from 38 studies (32 observational studies and 6 RCTs). The median follow-up duration was 6 months. The final BCVA was similar between PPV and PPV-SB (weighted mean difference [WMD], -0.03 logarithm of the minimum angle of resolution [-0.14 to 0.07]; P = 0.55). There was a significant difference in the single-operation success rate (SOSR) (88.2% versus 86.3%; relative risk [RR], 0.97 [0.95-1.00]; P = 0.03), favoring PPV-SB; however, there was no significant difference in the final reattachment rate (RR, 1.00 [0.99-1.01]; P = 0.56). Pars plana vitrectomy required a significantly higher number of operations to achieve final anatomical reattachment (WMD, 0.13 [0.02-0.24]; P = 0.02). In terms of complications, PPV was significantly less likely to be associated with macular edema (RR, 0.47 [0.25-0.88]; P = 0.02) and epiretinal membrane formation (RR, 0.70 [0.52-0.94]; P = 0.02), but these differences were no longer significant in studies published after 2010 or in RCTs. Significant proliferative vitreoretinopathy, lens status, and macular attachment status did not mediate differences in these effects. CONCLUSIONS There were no significant differences in the final visual acuity outcomes between PPV and PPV-SB. Pars plana vitrectomy with supplemental SB was associated with a greater SOSR than standalone PPV, although the magnitude of the effect was small, with a high number needed to treat. The final reattachment rate was similar. In recent studies and in RCTs, the risk of complications was similar between the procedures.

Abstract
TOPIC Diabetic macular edema (DME) can be treated with either intravitreal anti-VEGF injections or intravitreal corticosteroid injections. CLINICAL RELEVANCE We provide an updated meta-analysis of the comparative efficacy and safety of intravitreal steroids and anti-VEGF agents for DME. METHODS A systematic search was performed on Ovid MEDLINE, Embase, and Cochrane Controlled Register of Trials from January 2005 to November 2021. Inclusion criteria included published randomized clinical trial data comparing the efficacy and safety of intravitreal steroids versus anti-VEGF agents for DME. Nonrandomized, noncomparative, and non-English studies were excluded. RESULTS Fourteen randomized clinical trials reporting on 827 eyes were included. Between these 2 treatments, our analysis revealed no significant difference in best-corrected visual acuity (BCVA) outcomes at 3 months (P = 0.11), 6 months (P = 0.21), 12 months (P = 0.24), and final follow-up (P = 0.91). Retinal thickness was significantly lower with steroid treatment at 3 months (P = 0.04), 6 months (P < 0.00001), and final follow-up (weighted mean difference = 39.99 μm; 95% confidence interval [CI] = 14.58,65.41; P = 0.002); however, there was no significant difference at 12 months (P = 0.18). Intravitreal anti-VEGF agents were associated with a lower incidence of intraocular pressure-related adverse events (risk ratio = 0.13; 95% CI = 0.05, 0.34; P < 0.00001). There was no significant difference between comparators for other adverse events, including cataract-related adverse events (P = 0.22). CONCLUSIONS Overall, intravitreal steroid treatment for DME was associated with no significant differences in BCVA, a significantly lower retinal thickness, and a higher risk of intraocular pressure-related events. The certainty of evidence ranged from low to moderate and the analysis was limited by heterogeneity. Our results reinforce the importance of a continual reevaluation of the role of intravitreal steroids in DME management.

Abstract
Importance The association between residual subretinal fluid (SRF) and intraretinal fluid (IRF) and visual acuity following anti-vascular endothelial growth factor (VEGF) treatment is not well understood. Objective To examine the association of residual retinal fluid, SRF, and IRF with visual acuity following anti-VEGF treatment in patients with neovascular age-related macular degeneration (nAMD). Data Sources A systematic literature search was performed from January 2005 to August 2021 using Ovid MEDLINE, Embase, and the Cochrane Library. Study Selection Peer-reviewed articles reporting on visual acuity stratified by the presence or absence of any residual SRF, IRF, or any retinal fluid at last study observation after intravitreal bevacizumab, ranibizumab, aflibercept, or brolucizumab in patients with nAMD were included. Studies that were noncomparative, included fewer than 10 eyes, or reported on other anti-VEGF agents were excluded. Data Extraction and Synthesis Two independent reviewers conducted data extraction and synthesis. The Cochrane risk of bias tool 2 and ROBINS-I were used to assess risk of bias and GRADE evaluation was conducted to assess certainty of evidence. Main Outcomes and Measures Primary outcomes were BCVA at last study observation, change in BCVA from baseline, and retinal thickness at last study observation. Results In this systematic review and meta-analysis, 11 studies (6 randomized clinical trials [RCTs]) comprising 3092 eyes were included in our analysis. Across all included studies, the BCVA of eyes with residual SRF was better than eyes without SRF (weighted mean difference [WMD], 3.1 letter score; 95% CI, 0.05 to 6.18; P = .05; GRADE, low certainty of evidence; 6 studies; 1931 eyes) but similar in RCTs (WMD, 2.7 letter score; 95% CI, -2.40 to 7.84; P = .30; GRADE, low certainty of evidence; 3 studies; 1406 eyes). The BCVA of eyes with residual IRF was worse than that of eyes without IRF (WMD, -8.2 letter score; 95% CI, -11.79 to -4.50; P < .001; GRADE, low; 7 studies; 2114 eyes). Conclusions and Relevance The findings suggest that the presence of residual SRF was associated with slightly better BCVA at last study observation; however, baseline differences in BCVA existed and this conclusion was primarily driven by 1 study. The presence of residual IRF was associated with substantially worse BCVA at last study observation and less improvement of BCVA from baseline. The conclusions are limited by the inclusion of data from observational studies, heterogeneity, and a low certainty of evidence.

Abstract
PURPOSE The efficacy and safety of scleral buckling (SB) versus combination SB and pars plana vitrectomy (SB+PPV) for rhegmatogenous retinal detachment (RRD) repair remains unclear. METHODS A systematic review and meta-analysis was conducted to identify comparative studies published from Jan 2000-Jun 2021 that reported on the efficacy and/or safety following SB and SB+PPV for RRD repair. Final best-corrected visual acuity (BCVA) represented the primary endpoint, while reattachment rates and ocular adverse events were secondary endpoints. A random-effects meta-analysis was performed, and 95% confidence intervals were calculated. RESULTS Across 18 studies, 3912 SB and 3300 SB+PPV eyes were included. Final BCVA was non-significantly different between SB and SB+PPV (20/38 vs. 20/66 Snellen; WMD=-0.11 LogMAR; 95%CI [-0.29,0.07]; P=0.23). Primary reattachment rate was similar between procedures (P=0.74); however, SB alone achieved a significantly higher final reattachment rate (97.40% vs. 93.86%; RR=1.03; 95%CI [1.00,1.06]; P=0.04). Compared to SB+PPV, SB alone had a significantly lower risk of postoperative macular edema (RR=0.69; 95%CI [0.47,1.00]; P=0.05) and cataract formation (RR=0.34; 95%CI [0.12,0.96]; P=0.04). The incidence of macular hole, epiretinal membrane, residual subretinal fluid, proliferative vitreoretinopathy, elevated intraocular pressure, and extraocular muscle dysfunction were similar between SB and SB+PPV. CONCLUSIONS There was no significant difference in final BCVA between SB+PPV and SB alone in RRD. SB alone offers a slightly higher final reattachment rate along with a reduced risk of macular edema and cataract. Primary reattachment rate and the incidence of other complications were similar between the two procedures.

Abstract
Benign cutaneous vascular and cutaneous neoplasms arising from muscle or adipose tissue are rare. Their definition and classification are still controversially discussed. Histopathological and immunohistochemical studies, together with the new genetic tests, contribute significantly to the correct description of the various benign neoplasms of cutaneous origin. Clarifying whether a lesion is benign is fundamental for prognosis and therapeutic management. In most cases, surgical excision is the treatment of choice. Dermatologists should be familiar with the classifications of the most common benign cutaneous neoplasms of vascular, muscular, and adipose tissue and be able to recommend the procedures currently used for an accurate diagnosis. Ensuring that a lesion is benign and a good surgical outcome are essential for the patient.

Abstract
Pars plana vitrectomy (PPV) and scleral buckling (SB) are two of the most common surgical treatments for rhegmatogenous retinal detachment (RRD). This meta-analysis compares the efficacy and safety of PPV and SB for RRD. A systematic literature review was performed using Ovid MEDLINE, EMBASE and Cochrane CENTRAL from 2000 to June 2021. Comparative studies, randomized controlled trials and observational studies investigating PPV and SB for RRD repair were included. The primary endpoint was final best- corrected visual acuity (BCVA). Secondary endpoints were reattachment rates, total operation time, and incidence of adverse events. Subgroup analyses including phakic status, presence of PVR-C or greater at baseline, and macular attachment status were conducted. Across 41 studies (8 RCTs, 33 observational studies), 5,401 SB and 10,546 PPV eyes were included. SB achieved a statistically significant, but likely not clinically significant, better final BCVA than PPV (0.38 ± 0.53 vs. 0.33 ± 0.53 logMAR (20/48 vs. 20/43 Snellen); weighted mean difference [WMD]: 0.07; 95% confidence interval: [0.02-0.11]; P=0.005). SB had a better final BCVA compared to PPV in observational studies (P=0.007) but not in RCTs (P=0.21). SB had a lower incidence of post-operative cataract formation (P<0.00001) and iatrogenic breaks (P<0.00001), but a higher incidence of choroidal hemorrhage (P=0.007), choroidal detachment (P=0.004), and residual subretinal fluid (RSRF) (P<0.00001). Primary (86.5% vs. 84.8%; P=0.13) and final (96.7% vs. 97.7%; P=0.12) reattachment rates were similar between PPV and SB. PPV had a significantly higher primary reattachment rate in RCTs (P=0.02) but not in observational studies (P=0.30). SB was associated with a better final BCVA than PPV; however, this result was primarily driven by observational studies and phakic patients who developed cataracts. Primary and final reattachment rates were similar between the comparators. SB was associated with a significantly lower incidence of iatrogenic breaks and cataracts, while PPV was associated with a reduced risk of choroidal detachment, subretinal hemorrhage, and RSRF.

Abstract
Patients with chronic obstructive pulmonary disease (COPD) often also present with one or more cardiovascular risk factors, resulting not only in an increased mortality rate but also in a major impact on the health care system. Aside from common predisposing and environmental factors, the hypothesis of a chronic systemic inflammation linking COPD and cardiovascular co-morbidities is supported by an increasing body of evidence in recent literature. This could in turn pave the way for new developments, both diagnostic and therapeutic, in the future. In this context, the studies CoLaus and PneumoLaus aim to further investigate characteristics of the Lausanne general population, in particular those relating to cardiovascular and respiratory disease.

Abstract
Asthma is a chronic inflammatory airway disease, characterised by bronchial hyperresponsiveness causing bronchoconstriction, and thereby provoking typical symptoms (dyspnoea, cough, wheezing). Bronchial hyperres- ponsiveness indicates a temporary airflow limitation when exposed to a bronchoconstricting stimulus. Its measurement by challenge tests can be a valuable tool for confirming or excluding asthma, as well as for evaluating the efficacy of treatment. However, the origin of bronchial hyperresponsiveness is multifactorial and the different challenge tests are not equivalent. Direct challenge tests, like methacholine, mainly reflect chronic airway remo- delling, whereas indirect tests, like mannitol, better reflect bronchial inflammation.

Abstract
A 49 y.o. man was admitted for investigation of an intense fatigue associated with nausea, vomiting, weight loss and headache. Examination and work-up reveals a moderate hypercalcaemia and a panhypopituitarism attributed to a craniopharyngioma. Extensive work-up has excluded the most frequent causes of hypercalcaemia and we finally attributed this anomaly to the adrenal failure. In this article, we discuss the diagnostic approach, the etiology and physiopathology of this hypercalcemia and his association with endocrinological anomalies such as adrenal failure.
