A Comparative Study of Responses to Retina Questions from Either Experts, Expert-Edited Large Language Models, or Expert-Edited Large Language Models Alone.

Objective: To assess the quality, empathy, and safety of expert edited large language model (LLM), human expert created, and LLM responses to common retina patient questions. Design: Randomized, masked multicenter study. Participants: Twenty-one common retina patient questions were randomly assigned among 13 retina specialists. Methods: Each expert created a response (Expert) and then edited a LLM (ChatGPT-4)-generated response to that question (Expert + artificial intelligence [AI]), timing themselves for both tasks. Five LLMs (ChatGPT-3.5, ChatGPT-4, Claude 2, Bing, and Bard) also generated responses to each question. The original question along with anonymized and randomized Expert + AI, Expert, and LLM responses were evaluated by the other experts who did not write an expert response to the question. Evaluators judged quality and empathy (very poor, poor, acceptable, good, or very good) along with safety metrics (incorrect information, likelihood to cause harm, extent of harm, and missing content). Main Outcome: Mean quality and empathy score, proportion of responses with incorrect information, likelihood to cause harm, extent of harm, and missing content for each response type. Results: There were 4008 total grades collected (2608 for quality and empathy; 1400 for safety metrics), with significant differences in both quality and empathy (P < 0.001, P < 0.001) between LLM, Expert and Expert + AI groups. For quality, Expert + AI (3.86 ± 0.85) performed the best overall while GPT-3.5 (3.75 ± 0.79) was the top performing LLM. For empathy, GPT-3.5 (3.75 ± 0.69) had the highest mean score followed by Expert + AI (3.73 ± 0.63). By mean score, Expert placed 4 out of 7 for quality and 6 out of 7 for empathy. For both quality (P < 0.001) and empathy (P < 0.001), expert-edited LLM responses performed better than expert-created responses. There were time savings for an expert-edited LLM response versus expert-created response (P = 0.02). ChatGPT-4 performed similar to Expert for inappropriate content (P = 0.35), missing content (P = 0.001), extent of possible harm (P = 0.356), and likelihood of possible harm (P = 0.129). Conclusions: In this randomized, masked, multicenter study, LLM responses were comparable with experts in terms of quality, empathy, and safety metrics, warranting further exploration of their potential benefits in clinical settings.

Retinal detachment.

Retinal detachment (RD) occurs when the neurosensory retina, the neurovascular tissue responsible for phototransduction, is separated from the underlying retinal pigment epithelium (RPE). Given the importance of the RPE for optimal retinal function, RD invariably leads to decreased vision. There are three main types of RD: rhegmatogenous, tractional and exudative (also termed serous) RD. In rhegmatogenous RD, one or more retinal breaks enable vitreous fluid to enter the subretinal space and separate the neurosensory retina from the RPE. In tractional RD, preretinal, intraretinal or subretinal membranes contract and exert tangential forces and elevate the retina from the underlying RPE. Finally, in exudative RD, an underlying inflammatory condition, vascular abnormality or the presence of a tumour causes exudative fluid to accumulate in the subretinal space, exceeding the osmotic pump function of the RPE. The surgical management of RD usually involves pars plana vitrectomy, scleral buckling or pneumatic retinopexy. The approach taken often depends on patient characteristics as well as on practitioner experience and clinical judgement. Advances in surgical technology and continued innovation have improved outcomes for many patients. However, even if retinal re-attachment is achieved, some patients still experience decreased vision or other visual symptoms, such as metamorphopsia, that diminish their quality of life. Continued research in the areas of neuroprotection and retinal biology as well as continued surgical innovation are necessary to enhance therapeutic options and outcomes for these patients.

An Analysis of Solicitations from Predatory Journals in Ophthalmology.

PURPOSE: To evaluate trends associated with email communication from potentially predatory publishers to faculty in ophthalmology. DESIGN: Cross sectional study METHODS: Ophthalmologists (n=14) from various subspecialties and institutions were recruited to participate. Participants identified unsolicited emails they had received originating from publishers in May 2021. Information collected included details on email contents and publisher organizations. Trends in communications from predatory publishers were evaluated. RESULTS: Over a 30-day study period, a total of 1813 emails were received from 383 unique publishers and 696 unique journals with a mean (SD) of 4.73 (2.46) emails received per day per participant. Of the 1813 emails identified, 242 (13%) emails were invitations to conferences, whereas 1440 (80%) were solicitations for article submissions to open-access pay-to-publish journals. A total of 522 (29.0%) emails were related to ophthalmology, and reference to a prior publication of the participant occurred in 262 emails (14%). Of the 696 unique journals identified, 174 (25%) journals were indexed on PubMed and 426 (61%) were listed on Beall's list. When comparing journals listed on PubMed versus those that were not, PubMed indexed journals had a higher impact factor (2.1 vs 1.5, p=0.002), were less likely to use "greetings" (76% vs 91%, p<0.001), had fewer spelling/grammar errors (40% vs 51%, p=0.01), and were less likely to offer rapid publication (16% vs 25%, p=0.02). CONCLUSION: Unsolicited requests to publish occur frequently and may diminish the quality of the scientific literature. We encourage individuals in ophthalmology to be aware of these trends in predatory publishing.

ChatGPT enters the room: what it means for patient counseling, physician education, academics, and disease management.

PURPOSE OF REVIEW: This review seeks to provide a summary of the most recent research findings regarding the utilization of ChatGPT, an artificial intelligence (AI)-powered chatbot, in the field of ophthalmology in addition to exploring the limitations and ethical considerations associated with its application. RECENT FINDINGS: ChatGPT has gained widespread recognition and demonstrated potential in enhancing patient and physician education, boosting research productivity, and streamlining administrative tasks. In various studies examining its utility in ophthalmology, ChatGPT has exhibited fair to good accuracy, with its most recent iteration showcasing superior performance in providing ophthalmic recommendations across various ophthalmic disorders such as corneal diseases, orbital disorders, vitreoretinal diseases, uveitis, neuro-ophthalmology, and glaucoma. This proves beneficial for patients in accessing information and aids physicians in triaging as well as formulating differential diagnoses. Despite such benefits, ChatGPT has limitations that require acknowledgment including the potential risk of offering inaccurate or harmful information, dependence on outdated data, the necessity for a high level of education for data comprehension, and concerns regarding patient privacy and ethical considerations within the research domain. SUMMARY: ChatGPT is a promising new tool that could contribute to ophthalmic healthcare education and research, potentially reducing work burdens. However, its current limitations necessitate a complementary role with human expert oversight.

Conversion to faricimab after prior anti-vascular endothelial growth factor therapy for persistent diabetic macular oedema.

BACKGROUND: To assess the anatomical and functional outcomes in eyes with persistent diabetic macular oedema (pDME) on chronic anti-vascular endothelial growth factor therapy switched to intravitreal faricimab. METHODS: Patients with pDME on chronic anti-vascular endothelial growth factor therapy that were switched to faricimab and received at least three injections at our institution between April 2022 and May 2023 were included in this study. Patients were excluded if they had complete response to previous treatment but were switched to extend treatment intervals if they had steroid or laser treatment for DME within 6 months prior to switch. Clinical and imaging data were extracted from the electronic medical record. Central foveal thickness (CFT) and Snellen visual acuity (VA) were obtained before and after three intravitreal faricimab injections. Generalised estimating equations were used to analyse the change in CFT and VA. RESULT: During the study period, 69 eyes of 53 patients met inclusion criteria. The mean age was 68.6±9.0 years. The mean number of injections prior to switch was 18.1±16.0. Pre-switch mean logarithm of the minimal angle of resolution VA was 0.40±0.30 (Snellen equivalent 20/50) and 0.38±0.27 (Snellen equivalent 20/48) after three faricimab injections (p=0.397). Mean CFT improved from 380±155 microns to 323±147 microns (p<0.001). No ophthalmic or systemic adverse events occurred during the study period. CONCLUSIONS: Intravitreal faricimab can improve anatomic outcomes while maintaining visual acuity in eyes with pDME previously treated with anti-VEGF therapy.

Trends in the Clinical Presentation of Uveal Melanoma During the COVID-19 Pandemic.

BACKGROUND AND OBJECTIVE: The objective was to evaluate factors associated with clinical presentation of uveal melanoma (UM) during the initial two years of the coronavirus disease 2019 pandemic. PATIENTS AND METHODS: This was a multi-site, retrospective cohort study of patients treated for uveal melanoma during the first (early) and second (late) year of the pandemic compared with the year prior (control). RESULTS: A total of 48, 67, and 75 patients were in the control, early, and late cohorts, respectively. The early cohort had a higher frequency of large tumors (control: 29.2%, early: 40.3%, late: 29.3%; P < 0.001) at presentation. Both the early and late cohorts had higher rates of enucleation (control: 8.33%, early: 20.9%, late: 18.67%; P ≤ 0.0338) compared to the control cohort. CONCLUSIONS: While there was an increase in large tumors along with a rise in enucleation during the first year of the pandemic, enucleation rates remained elevated even while tumor sizes normalized.

Hospitalization, Overdose, and Mortality After Opioid Prescriptions Tied to Ophthalmic Surgery.

PURPOSE: Opioid prescriptions continue to carry significant short- and long-term systemic risks, even after ophthalmic surgery. The goal of this study was to identify any association of opioid prescription, after ophthalmic surgery, with postoperative hospitalization, opioid overdose, opioid dependence, and all-cause mortality. DESIGN: Retrospective, cross-sectional analysis. PARTICIPANTS: Patients undergoing an ophthalmic surgery in the OptumLabs Data Warehouse. METHODS: We used deidentified administrative claims data from the OptumLabs Data Warehouse to create 3 cohorts of patients for analysis from January 1, 2016, to June 30, 2022. The first cohort consisted of 1-to-1 propensity score-matched patients who had undergone ophthalmic surgery and had filled a prescription for an opioid and not filled a prescription for an opioid. The second cohort consisted of patients who were considered opioid naïve and had filled a prescription for an opioid matched to patients who had not filled a prescription for an opioid. The last cohort consisted of opioid-naïve patients matched across the following morphine milligram equivalents (MME) groups: ≤ 40, 41-80, and > 80. MAIN OUTCOME MEASURES: Short- and long-term risks of hospitalization, opioid overdose, opioid dependency/abuse, and death were compared between the cohorts. RESULTS: We identified 1 577 692 patients who had undergone an ophthalmic surgery, with 312 580 (20%) filling an opioid prescription. Among all patients, filling an opioid prescription after an ophthalmic surgery was associated with increased mortality (hazard rate [HR], 1.28; 95% confidence interval [CI], 1.25-1.31; P < 0.001), hospitalization (HR, 1.51; 95% CI, 1.49-1.53; P < 0.001), opioid overdose (HR, 7.31; 95% CI, 6.20-8.61, P < 0.001), and opioid dependency (HR, 13.05; 95% CI, 11.48-14.84; P < 0.001) compared with no opioid prescription. Furthermore, we found that higher MME doses of opioids were associated with higher rates of mortality, hospitalization, and abuse/dependence. CONCLUSIONS: Patients who filled an opioid prescription after an ophthalmic surgery experienced higher rates of mortality, hospitalization, episodes of opioid overdose, and opioid dependence compared with patients who did not fill an opioid prescription.

Risk of Endophthalmitis Based on Cumulative Number of Anti-VEGF Intravitreal Injections.

PURPOSE: To determine the risk of endophthalmitis in eyes undergoing intravitreal injections (IVIs) of anti-VEGF based on cumulative number of injections per eye. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients from a single center undergoing IVIs of ranibizumab, aflibercept, or bevacizumab. METHODS: Eyes were divided into quartiles based on injection number causative of endophthalmitis between January 1, 2011, and June 1, 2022. MAIN OUTCOME MEASURES: Interquartile clinical outcomes and cumulative risk of endophthalmitis per injection and per eye. RESULTS: A total of 43 393 eyes received 652 421 anti-VEGF injections resulting in 231 endophthalmitis cases (0.035% per injection, 1 in 2857), of which 215 were included. The cumulative endophthalmitis risk increased from 0.0018% (1 in 55 556) after 1 injection to 0.013% (1 in 7692) after 11 injections (0.0012 percentage point change), versus 0.014% (1 in 7143) after 12 injections to 0.025% (1 in 4000) after 35 injections (0.00049 percentage point change), versus 0.025% (1 in 4000) after 36 injections to 0.031% (1 in 3226) after 66 injections (0.00017 percentage point change), versus 0.031% (1 in 3226) after 63 injections to 0.033% (1 in 3030) after 126 injections (0.000042 percentage point change) (P < 0.001). Likewise, the cumulative endophthalmitis risk per eye increased from 0.028% (1 in 3571) to 0.20% (1 in 500) between injections 1 and 11 (0.018 percentage point change), versus 0.21% (1 in 476) to 0.38% (1 in 263) between injections 12 and 35 (0.0075 percentage point change), versus 0.38% (1 in 263) to 0.46% (1 in 217) between injections 36 and 66 (0.0026 percentage point change), versus 0.46% (1 in 217) to 0.50% (1 in 200) between injections 67 and 126 (0.00063 percentage point change) (P < 0.001). CONCLUSIONS: The cumulative endophthalmitis risk per injection and per eye increased with greater number of injections received but appeared to do so at a higher rate during earlier injections and at a lower rate further into the treatment course.

Artificial Intelligence, Digital Imaging, and Robotics Technologies for Surgical Vitreoretinal Diseases.

OBJECTIVE: To review recent technological advancement in imaging, surgical visualization, robotics technology, and the use of artificial intelligence in surgical vitreoretinal (VR) diseases. BACKGROUND: Technological advancements in imaging enhance both preoperative and intraoperative management of surgical VR diseases. Widefield imaging in fundal photography and OCT can improve assessment of peripheral retinal disorders such as retinal detachments, degeneration, and tumors. OCT angiography provides a rapid and noninvasive imaging of the retinal and choroidal vasculature. Surgical visualization has also improved with intraoperative OCT providing a detailed real-time assessment of retinal layers to guide surgical decisions. Heads-up display and head-mounted display utilize 3-dimensional technology to provide surgeons with enhanced visual guidance and improved ergonomics during surgery. Intraocular robotics technology allows for greater surgical precision and is shown to be useful in retinal vein cannulation and subretinal drug delivery. In addition, deep learning techniques leverage on diverse data including widefield retinal photography and OCT for better predictive accuracy in classification, segmentation, and prognostication of many surgical VR diseases. CONCLUSION: This review article summarized the latest updates in these areas and highlights the importance of continuous innovation and improvement in technology within the field. These advancements have the potential to reshape management of surgical VR diseases in the very near future and to ultimately improve patient care.

Trends in Geographic Distribution of Visual Disability - United States, 2010-2019.

PURPOSE: We aimed to describe changes in the geographic distribution of self-reported visual impairment (VI) over the last decade (2010-2019) in the U.S. METHODS: Our study was an analysis of publicly available data collected between 2010 and 2019 from the Census Bureau American Community Survey. RESULTS: The mean overall prevalence of self-reported VI from 2010 to 2019 was 2.31% in the United States, and there was a significant increase in VI over the past decade from 2.25% in 2010-2014 to 2.37% in 2015-2019 (p < .001). VI was significantly higher in rural counties (3.58%), compared to urban (3.10%) or metropolitan counties (2.18%) (p < .001). In terms of geographic region, the South of the United States had the highest rate of VI (2.63%) (p < .001). For age groups > 17-years-old in the 2010-2019 data, women had higher rates of VI compared to men. CONCLUSIONS: Prevalence of self-reported visual impairment has risen and disproportionately affects certain communities. This includes individuals living in the South, in rural counties, and women.

Surgical Management of Full-Thickness Macular Holes in Macular Telangiectasia Type 2: A Global Multicenter Study.

PURPOSE: To report on macular hole repair in macular telangiectasia type 2 (MacTel2). DESIGN: Global, multicenter, retrospective case series. PARTICIPANTS: Patients undergoing surgery for MacTel2-associated full-thickness macular hole (MTMH). METHODS: Standardized data collection sheet distributed to all surgeons. MAIN OUTCOME MEASURES: Anatomic closure and visual outcomes of MTMH. RESULTS: Sixty-three surgeries in 47 patients with MTMH were included from 30 surgeons. Mean age was 68.1 years, with 62% female, 72% White, 21% East or South Asian, 2% African American, and 2% Hispanic or Latino. Procedures included 34 internal limiting membrane (ILM) peeling alone, 22 ILM flaps, 5 autologous retinal transplantations (ARTs), 1 retinotomy, and 1 subretinal bleb. For ILM peeling, preoperative visual acuity (VA) was 0.667 ± 0.423 logarithm of the minimum angle of resolution (logMAR). Minimum hole diameter (MHD) was 305.5 ± 159.4 µm (range, 34-573 µm). Sixteen of 34 ILM peels (47%) resulted in MTMH closure. At postoperative month 6, VA was stable at 0.602 ± 0.516 logMAR (P = 0.65). VA improved by at least 2 lines in 43% and at least 4 lines in 24%. For ILM flaps, preoperative VA was 0.878 ± 0.552 logMAR. MHD was 440.8 ± 175.5 µm (range, 97-697 µm), which was significantly larger than for ILM peels (P < 0.01). Twenty of 22 ILM flaps (90%) resulted in MTMH closure, which was significantly higher than for ILM peels (P < 0.01). At postoperative month 6, VA improved to 0.555 ± 0.405 logMAR (P < 0.05). VA improved by at least 2 lines in 56% and at least 4 lines in 28%. For ARTs, preoperative VA was 1.460 ± 0.391 logMAR. MHD was 390.2 ± 203.7 µm (range, 132-687 µm). All 5 ARTs (100%) resulted in MTMH closure. At postoperative month 6, VA was stable at 1.000 ± 0.246 logMAR (P = 0.08). Visual acuity improved at least 2 lines in 25%. CONCLUSIONS: Surgical closure of macular holes improved VA in 57% of MTMHs. Internal limiting membrane flaps achieved better anatomic and functional outcomes than ILM peeling alone. Autologous retinal transplantation may be an option for refractory MTMHs.

IMPACT OF FOVEAL STATUS AND TIMING OF SURGERY ON VISUAL OUTCOME IN RHEGMATOGENOUS RETINAL DETACHMENT.

PURPOSE: To investigate the impact of surgical timing on visual acuity outcomes in retinal detachments based on the preoperative foveal status. METHODS: A retrospective multicenter cohort study was conducted. Cases were stratified into fovea-on, fovea-split, and fovea-off groups. Days to surgery was defined as the time between the preoperative examination and surgery. The main outcome measure was the final postoperative visual acuity. RESULTS: 1,675 cases were studied. More than 80% of fovea-on/fovea-split and fovea-off cases had surgery within 1 and 3 days, respectively. The mean final postoperative visual acuity did not differ significantly between the fovea-on and fovea-split groups (Snellen equivalent [SE] 20/33 ± 20/49 and 20/32 ± 20/39, P = 1.000) and did not change significantly based on days to surgery in either group. The mean final postoperative visual acuity was lowest in the fovea-off group (Snellen equivalent = 20/56 ± 20/76, P < 0.001) and was significantly lower in cases where surgery was performed after two or more days when compared with cases performed within 1 day (Snellen equivalent 20/74 ± 20/89 vs. 20/46 ± 20/63, P < 0.001). CONCLUSION: Fovea-on and fovea-split retinal detachments demonstrated comparable visual outcomes. Fovea-off RDs demonstrated worse visual outcomes, which declined further when surgery was delayed by two or more days.

RIDGE-SHAPED PERIPAPILLA.

PURPOSE: To report a case of peripapillary subretinal fluid associated with a ridge-shaped morphology surrounding the optic disk, which we termed ridge-shaped peripapilla. METHODS: Case report. RESULTS: A 6-year-old girl with mild-to-moderate myopia was referred for an abnormal fundus appearance of the left eye. Fundus examination of the left eye showed a vertical whitish elevation just temporal to the disk with pigment clumping. Spectral domain optical coherence tomography of the left eye showed an elevation of the fundus at the temporal edge of the disk with thinning of the choroid overlying the thickened scleral protrusion and a serous subretinal fluid. Fluorescein angiography of the left eye showed a hyperfluorescent area without leakage at the temporal edge of the disk, indicative of retinal pigment epithelium atrophy. There was no sign of choroidal neovascularization. Based on the fluorescein angiography and optical coherence tomography findings, the protrusion of the sclera seemed to result in overlying choroidal thinning with choroidal blood flow disturbances, and consequent retinal pigment epithelium atrophy, leading to the subretinal fluid. CONCLUSION: This case highlights an unusual presentation of ridge-shaped peripapilla, characterized by inward convexity of the peripapillary area with a ridge-shaped morphology and localized thickening of the peripapillary sclera, in eyes with myopia.

Clinical Outcomes of Faricimab in Patients with Previously Treated Neovascular Age-Related Macular Degeneration.

PURPOSE: To assess the anatomic and functional outcomes in eyes with neovascular age-related macular degeneration (nAMD) previously treated with anti-VEGF therapy in response to intravitreal faricimab. DESIGN: Retrospective, interventional, consecutive case series. SUBJECTS: Patients with previously treated nAMD who received ≥ 4 consecutive injections of faricimab were included. The study period was from March through November 2022. METHODS: Clinical and imaging data were extracted from the electronic medical record. Central foveal thickness (CFT), maximum fibrovascular pigment epithelial detachment (fvPED) height, and Snellen visual acuity (VA) were obtained. Generalized estimating equations were used to analyze the change in CFT, maximum fvPED height, and logarithm of the minimum angle of resolution VA. MAIN OUTCOME MEASURES: Change in CFT, maximum fvPED height, and Snellen VA before faricimab and after ≥ 4 faricimab intravitreal injections. RESULTS: During the study period, 218 eyes of 191 patients met inclusion criteria. Mean age was 79.9 (range, 70.6-89.2) years. The mean number of intravitreal anti-VEGF injections received before faricimab was 34.2 (range, 6.4-62). The following results were found after ≥ 4 faricimab injections. Mean logarithm of the minimum angle of resolution VA before switching to faricimab was 0.58 (Snellen VA ∼20/76; range, 20/22-20/264) and was 0.55 (Snellen VA ∼20/71; range, 20/21-20/235; P = 0.20) after switching. Mean maximum fvPED height was 195.0 (range, 50.2-339.8) µm before switching to faricimab and improved to 165.0 (range, 33.6-296.4; P < 0.001) µm after switching. Mean CFT was 354.8 (range, 184.7-524.9) µm before switching to faricimab and improved to 306.6 (range, 144.4-468.8; P < 0.001) after switching. The proportion of eyes with intraretinal fluid was 36.7% (80/218 eyes) before switching, and decreased to 24.8% (54/218 eyes, P < 0.001) after switching. The proportion of eyes with subretinal fluid was 53.2% (116/218 eyes) before switching and decreased to 26.6% (58/218 eyes, P < 0.001) after switching. CONCLUSIONS: Intravitreal faricimab may improve anatomic outcomes in patients with previously treated nAMD, while maintaining VA in the short-term.
