Cardiovascular risk in anti-VEGF treatment of neovascular age-related macular degeneration.

OBJECTIVE: Assess 5-year all-cause mortality (ACM), hemorrhagic stroke, ischemic stroke, and myocardial infarction (MI) risks in nAMD patients receiving anti-VEGF injections compared with controls. DESIGN: Population-based retrospective cohort study using a U.S. federated health research network, containing de-identified data of 96 million patients from 1/1/2003 to 3/6/2023. PARTICIPANTS: nAMD Patients with anti-VEGF injections. Controls included nAMD patients without anti-VEGF injections, non-exudative AMD patients, and patients without AMD. METHODS: Patients were identified using nAMD ICD-10 and anti-VEGF CPT codes and matched for age, sex, and comorbidities. Five-year relative risk of ACM (RR1), hemorrhagic stroke (RR2), ischemic stroke (RR3), and MI (RR4) in nAMD patients receiving anti-VEGF injections were calculated. RESULTS: A total of 27,609 nAMD patients (mean diagnosis age [SD], [78.2 (10.3)]) received anti-VEGF injections; 769 nAMD patients without injections (75.8 [12.2]), 27,599 non-exudative AMD patients (78.2 [10.3]), and 21,902 no-AMD patients (76.1 [10.5]) were identified. After matching, nAMD patients receiving injections did not show increased risk versus nAMD patients without injections (RR1, 0.66; 95% CI [0.53, 0.82]), (RR2, 1.00 [0.42, 2.38]), (RR3, 1.70 [0.92,3.13]), (RR4, 0.63 [0.33, 1.18]). No increased risk was found compared to non-exudative AMD patients (RR1, 0.99 [0.95, 1.03]), (RR2, 0.94 [0.83,1.07]), (RR3, 1.04 [0.96, 1.12]), (RR4, 0.99 [0.91, 1.08]). Increased risk for ACM was observed versus no-AMD patients (RR1, 1.21 [1.15, 1.27]), but no other differences were found (RR2, 0.81 [0.70, 0.93]), (RR3, 1.00 [0.92, 1.09]), (RR4, 0.986 [0.90, 1.09]). CONCLUSION: Anti-VEGF injections were not associated with major cardiovascular events in nAMD patients over 5 years.

Melatonin and Risk of Age-Related Macular Degeneration.

Importance: Melatonin has been shown to oppose several processes that are known to mediate age-related macular degeneration (AMD), but whether melatonin can confer benefits against AMD remains unclear. Objective: To examine the association between melatonin supplementation and the risk of the development or progression of AMD. Design, Setting, and Participants: This retrospective cohort study accessed data from TriNetX, a national database of deidentified electronic medical records from both inpatient and outpatient health care organizations across the US, between December 4, 2023, and March 19, 2024. Patients aged 50 years or older, 60 years or older, and 70 years or older with no history of AMD (AMD-naive group) and with a history of nonexudative AMD (nonexudative AMD group) were queried for instances of melatonin medication codes between November 14, 2008, and November 14, 2023. Patients were then classified into either a melatonin group or a control group based on the presence of medication codes for melatonin. Propensity score matching (PSM) was performed to match the cohorts based on demographic variables, comorbidities, and nonmelatonin hypnotic medication use. Exposure: The presence of at least 4 instances of melatonin records that each occurred at least 3 months apart. Main Outcomes and Measures: After PSM, the melatonin and the control cohorts were compared to evaluate the risk ratios (RRs) and the 95% CIs of having an outcome. For the AMD-naive group, the outcome was defined as a new diagnosis of any AMD, whereas for the nonexudative AMD group, the outcome was progression to exudative AMD. Results: Among 121 523 patients in the melatonin-naive group aged 50 years or older (4848 in the melatonin cohort [4580 after PSM; mean (SD) age, 68.24 (11.47) years; 2588 female (56.5%)] and 116 675 in the control cohort [4580 after PSM; mean (SD) age, 68.17 (10.63) years; 2681 female (58.5%)]), melatonin use was associated with a reduced risk of developing AMD (RR, 0.42; 95% CI, 0.28-0.62). Among 66 253 patients aged 50 years or older in the nonexudative AMD group (4350 in the melatonin cohort [4064 after PSM; mean (SD) age, 80.21 (8.78) years; 2482 female (61.1%)] and 61 903 in the control cohort [4064 patients after PSM; mean (SD) age, 80.31 (8.03) years; 2531 female (62.3%)]), melatonin was associated with a reduced risk of AMD progression to exudative AMD (RR, 0.44; 95% CI, 0.34-0.56). The results were consistent among subsets of individuals aged 60 years or older (AMD-naive cohort: RR, 0.36 [95% CI, 0.25-0.54]; nonexudative AMD cohort: RR, 0.38 [95% CI, 0.30-0.49]) and 70 years or older (AMD-naive cohort: RR, 0.35 [95% CI, 0.23-0.53]; nonexudative AMD cohort: RR, 0.40 [95% CI, 0.31-0.51]). Conclusions and Relevance: Melatonin use was associated with a decreased risk of development and progression of AMD. Although lifestyle factors may have influenced this association, these findings provide a rationale for further research on the efficacy of using melatonin as a preventive therapy against AMD.

Longitudinal Trends and Disparities in Diabetic Retinopathy Within an Aggregate Health Care Network.

Importance: Diabetic retinopathy (DR) is a leading cause of blindness in the US, warranting updates on its prevalence and incidence in the setting of advancements in diabetic care over recent years. Objective: To determine recent trends in DR prevalence stratified by baseline demographics to identify those populations at greater risk. Design, Setting, and Participants: This was a cross-sectional epidemiologic evaluation conducted using deidentified data from the large federated TriNetX Analytics health research network composed of 56 health care organizations in the US. Patients from 2015 to 2022 who had an International Statistical Classification of Diseases and Related Health Problems, Tenth Revision code of type 1 DR (T1DR) or type 2 DR (T2DR) were included in this analysis. Patients were further stratified by age cohorts (20-29 years, 30-39 years, 40-49 years, 50-59 years, 60-69 years, and 70 years or older), race and ethnicity, and sex. Main Outcomes and Measures: Prevalence per 100 000 patients and prevalence odds ratios (ORs) were calculated in Microsoft Excel and Posit (formerly RStudio). Results: A total of 359 126 patients with T1DR or T2DR (mean [SD] age, 67 [14] years; 52% female) were included in this study between January 1, 2015, and December 21, 2022. T1DR increased in prevalence from 2015 to 2022, with T1DR increasing 1.15-fold affecting 70.4 patients per 100 000 in 2022. T2DR increased 1.07-fold affecting 461.7 patients per 100 000 in 2022. For T1DR, the cohort aged 20 to 39 years had the most substantial increase at 4.7 and 1.96 fold. Overall, White males had the largest prevalence ORs of T1DR at 1.41 (95% CI, 1.36-1.47) compared with White females (reference group). In T2DR, patients aged 20 to 39 years again had a 2.5- and 1.6-fold prevalence increase from 2015 to 2022. Regardless of age group, Hispanic males demonstrated larger prevalence OR at 4.08 (95% CI, 3.97-4.19) compared with White females followed by Hispanic females at 2.49 (95% CI, 2.42-2.56), Black males at 2.23 (95% CI, 2.17-2.29), and Black females at 2.00 (95% CI, 1.95-2.05). Conclusion and Relevance: The prevalence of both T1DR and T2DR increased in this network from 2015 to 2022, with individuals aged 20 to 39 years showing large increases. Additionally, T2DR was associated with greater increases in both Hispanic and Black communities. These findings support DR screening in young adults and for T2DR interventions specifically designed for racial and ethnic minoritized patients most affected by disease. Future investigations are warranted to further investigate these trends among young adults.

Characterisation and Visual Outcomes of Fulminant Idiopathic Intracranial Hypertension: A Narrative Review.

Fulminant idiopathic intracranial hypertension (IIH) is a rapid vision-degrading presentation of IIH with limited published studies. This study composed a narrative review of fulminant IIH with the aim of better characterising fulminant IIH presentation and visual outcomes. SCOPUS and PubMed were searched for papers referencing IIH, benign intracranial hypertension, or pseudotumour cerebri. Abstracts were screened for rapid degradation in vision. All studies were required to meet both the modified Dandy and fulminant IIH criteria. Thirty-six studies met the inclusion criteria. Demographics, treatments, and visual outcome data were collected. Case studies made up 69% of the studies and 31% were case series. In total, 72 patients with fulminant IIH were reported, of which 23.6% were paediatric and 96% were female. Surgical intervention occurred in 85% of patients. Anaemia was present in 11% of patients and 85.7% of paediatric patients had a sixth cranial nerve palsy. In conclusion, we propose the following practice guidelines to assist in diagnosing and treating fulminant IIH patients: 1) patients who present with optic disc oedema require urgent visual field testing to evaluate for vision loss; 2) a paediatric patient presenting with a sixth cranial nerve palsy should have a comprehensive eye examination; 3) fulminant IIH can occur in patients with a normal body mass index; and 4) anaemia should be tested for in the setting of fulminant IIH. As little is known about the optimal treatment mechanisms for this presentation, multi-institutional and international collaborations will be a critical step for future research.

Automated Evaluation of Ellipsoid Zone At-Risk Burden for Detection of Hydroxychloroquine Retinopathy.

BACKGROUND: Screening for hydroxychloroquine (HCQ) retinopathy is crucial to detecting early disease. A novel machine-learning-based optical coherence tomography (OCT) biomarker, Ellipsoid Zone (EZ) At-Risk, can quantitatively measure EZ alterations and at-risk areas for progressive EZ loss in a fully automated fashion. The purpose of this analysis was to compare the EZ At-Risk burden in eyes with HCQ toxicity to eyes without toxicity. METHODS: IRB-approved image analysis study of 83 subjects on HCQ and 44 age-matched normal subjects. SD-OCT images were reviewed for evidence of HCQ retinopathy. A ML-based, fully automatic measurement of the percentage of the macular area with EZ At-Risk was performed. RESULTS: The mean age for HCQ subjects was 67.1 ± 13.2 years and 64.2 ± 14.3 years for normal subjects. The mean EZ At-Risk macular burden in the "toxic" group (n = 38) was significantly higher (10.7%) compared to the "non-toxic" group (n = 45; 2.2%; p = 0.023) and the "normal" group (1.4%; p = 0.012). Additionally, the amount of EZ At-Risk burden was significantly correlated with the HCQ dose based on the actual (p = 0.016) and ideal body weight (p = 0.033). CONCLUSIONS: The novel biomarker EZ-At Risk was significantly higher in subjects with evidence of HCQ retinopathy as well as significantly associated with HCQ dose. This novel biomarker should be further evaluated as a potential screening tool for subjects on HCQ.

Comparing Three-Dimensional Digitally Enabled Intraoperative OCT With Conventional Microscope-Integrated OCT in Vitreoretinal Surgery: A Post Hoc Analysis of the DISCOVER Study.

BACKGROUND AND OBJECTIVE: This study compared the surgeon experience between conventional microscope-integrated intraoperative optical coherence tomography (iOCT) and digitally enabled microscope-integrated iOCT in vitreoretinal surgery. PATIENTS AND METHODS: This is a post hoc case-control analysis of the DISCOVER study. Conventional microscope-integrated iOCT (Rescan 700, Zeiss) was compared with digitally enabled iOCT (Artevo 800, Zeiss). Compared variables included surgical field-based visualization (ie, ocular heads-up display in the conventional group; three-dimensional screen-based visualization in the digital iOCT group) and non-surgical field-based visualization (ie, review on the external two-dimensional monitor). RESULTS: A total of 200 patients were included. Surgical field-based visualization of iOCT was significantly higher in the digitally enabled group (P < 0.0001). Required endoillumination level was significantly lower in the digital iOCT group (P < 0.0001). Surgeons reported "significant" back discomfort and headache more frequently when using conventional iOCT (P = 0.003 and P = 0.001, respectively). CONCLUSIONS: Digitally enabled iOCT resulted in greater surgical visualization efficiency, appeared to require a lower illumination level, and may provide advantages for ergonomic-related discomfort.

Incidence of ocular pathology following bariatric surgery for with morbid obesity across a large United States National Database.

BACKGROUND/OBJECTIVES: Bariatric surgery, as indicated for treatment of morbid obesity, has been studied in association with short term effects on ocular pathology. However, effects of surgery on postoperative disease incidence is largely unknown. SUBJECTS/METHODS: In this retrospective cohort study, the TriNetX United States Collaborative Network national database, was queried for patients with an ICD-10 code for morbid obesity and a procedural code for bariatric surgery. Patients were propensity score matched across baseline demographics at the time of surgery and compared to those presenting with an ICD10 code for morbid obesity with no records of a procedural code for bariatric surgery, identifying 42,408 patients per cohort. New diagnoses or procedural codes found after the surgical index date for diabetic retinopathy, age-related macular degeneration, glaucoma, low vision, and blindness along with pertinent treatment metrics were monitored. RESULTS: Bariatric surgery was found to be associated with reduced future risk of diabetic retinopathy (RR: 0.283; 95% CI: 0.252-0.319), macular edema (RR: 0.224; 95% CI: 0.170-0.297), vitreous hemorrhage (RR: 0.459; 95% CI: 0.323-0.653), ocular hypertension (RR: 0.387; 95% CI: 0.387-0.487), glaucoma (RR: 0.360; 95% CI: 0.326-0.399), use of ocular pressure lowering medications (RR: 0.565; 95% CI: 0.496-0.644), age-related macular degeneration (RR: 0.628; 95% CI: 0.447-0.882), cataract surgery (RR: 0.524; 95% CI: 0.448-0.612), and low vision and blindness (RR: 0.328; 95% CI: 0.294-0.365) compared to patients not surgically managed. CONCLUSIONS: The present analysis comprising a large US cohort of patients suggests that bariatric surgery is associated with a decreased risk of future ocular morbidity and mortality.

Real-world effects of anti-vascular endothelial growth factor injection frequency on visual outcomes in patients with diabetic macular oedema.

BACKGROUND AND OBJECTIVE: Anti-vascular endothelial growth factor (VEGF) injections are often administered less frequently in real-world treatment of diabetic macular oedema (DMO) than what was studied in clinical trials. This study aims to characterise real-world DMO treatment patterns and the effect of treatment intervals on patient outcomes. STUDY DESIGN/PATIENTS AND METHODS: This was a retrospective study of 291 patients with DMO treated with anti-VEGF therapy. 12- and 24-month best visual acuity (BVA) and central subfield thickness (CST) were compared between injection interval groups, which were determined by averaging the two most recent injection intervals. Multiple linear regressions were performed to identify factors associated with injection interval, BVA, and CST. RESULTS: 48.8% of patients received injections less than or equal to every 8 weeks (≤ q8w), 27.5% between every 8 to 12 weeks (q8-12w), and 23.7% greater than every 12 weeks (> q12w). Baseline CST was similar (p = 0.32), but BVA differed significantly in q8-12w patients (p = 0.0095). BVA and CST at 12 months were similar, but q8-12w patients experienced greater 12-month BVA improvement (7.36 ± 12.4 letters) than > q12w patients (1.26 ± 12.3 letters; p = 0.0056). 24-month BVA and CST changes were similar between groups (p = 0.30 and 0.87). Baseline BVA, HbA1c, and sex were associated with 12-month BVA, and baseline BVA and CST were associated with 12-month CST. CONCLUSION: Many patients experienced improvements in BVA and CST over 12 months of treatment despite receiving less frequent anti-VEGF therapy than recommended in the pivotal trials. The present study showed that extended treatment intervals with bevacizumab were effective in preserving vision of many individuals with high baseline BVA.

Compartmental Exudative Dynamics in Neovascular Age-Related Macular Degeneration: Volumetric Outcomes and Impact of Volatility in a Phase III Clinical Trial.

PURPOSE: To examine retinal feature dynamics in eyes with neovascular age-related macular degeneration (nAMD) treated with anti-VEGF therapy and the relationship of these features with visual acuity. DESIGN: Post hoc analysis of the phase III, randomized, HAWK nAMD clinical trial. PARTICIPANTS: Participants randomized to the brolucizumab 6 mg or aflibercept 2 mg arms of the trial. METHODS: Spectral-domain OCT scans collected at 4-week intervals were analyzed using an automated machine learning-enhanced segmentation and feature-extraction platform with manual verification. Quantitative volumetric measures of retinal and exudative features were exported at multiple timepoints over 48 weeks. Volatility of exudative features was calculated as the standard deviation of each feature value during the maintenance phase (week 12-48) of treatment. These features were examined for their associations with anatomic and functional outcomes. MAIN OUTCOME MEASURES: Longitudinal intraretinal fluid (IRF) and subretinal fluid (SRF) volume, subretinal hyperreflective material (SHRM) volume, ellipsoid zone (EZ) integrity (EZ-retinal pigment epithelium [RPE] volume/thickness), and correlation with best-corrected visual acuity (BCVA). RESULTS: Intraretinal fluid, SRF, and SHRM demonstrated significant volumetric reduction from baseline with anti-VEGF therapy (P < 0.001 at each timepoint). Ellipsoid zone integrity measures demonstrated significant improvement from baseline (P < 0.001 at each timepoint). Both EZ integrity and SHRM measures correlated significantly with BCVA at all timepoints (EZ-RPE volume: 0.38 ≤ r ≤ 0.47; EZ-RPE central subfield thickness: 0.22 ≤ r ≤ 0.41; SHRM volume: -0.33 ≤ r ≤ -0.44). After treatment initiation, correlations of IRF and SRF volume with BCVA were weak or nonsignificant. Eyes with lower volatility of IRF, SRF, and SHRM volumes during the maintenance phase showed greater improvements in EZ integrity (all P < 0.01) and greater gains in BCVA (all P < 0.01) at week 48 compared with eyes with higher volatility in those exudative parameters. CONCLUSIONS: Quantitative measures of SHRM volume and EZ integrity correlated more strongly with BCVA than retinal fluid volumes during treatment. High volatility of exudative parameters, including SRF, during the maintenance phase of treatment was associated with loss of EZ integrity and BCVA.

The Risk of Optic Neuritis following mRNA Coronavirus Disease 2019 Vaccination Compared to Coronavirus Disease 2019 Infection and Other Vaccinations.

PURPOSE: To determine the risk of optic neuritis (ON) after mRNA Coronavirus Disease 2019 (COVID-19) vaccine administration. DESIGN: U.S. National aggregate database retrospective cohort study. PARTICIPANTS: Patients were placed into cohorts based on mRNA COVID-19 vaccination status (no vaccine and positive history of COVID-19 infection, 1 vaccine, or 2 vaccines received) from December 2020 to June 2022. Two control cohorts were created with patients vaccinated against influenza or tetanus diphtheria and pertussis (Tdap) from June 2018 to December 2019. Patients with any history of ON or significant risk factors for ON development including infectious, inflammatory, and neoplastic diseases were excluded. METHODS: A large deidentified database was queried for the Common Procedural Technology codes for immunization encounters specific to first dose and second dose of mRNA COVID-19 vaccine, influenza, or Tdap. Cohorts were 1:1 propensity score matched on age, sex, race, and ethnicity. The risk of ON development after vaccination was calculated and compared for all 5 cohorts with 95% confidence intervals (CIs) reported. MAIN OUTCOME MEASURES: Risk ratio (RR) of ON 21 days after vaccination (or COVID-19 infection) and incidence of ON per 100 000 individuals. RESULTS: After matching, the first dose COVID-19 and influenza vaccine cohorts (n = 1 678 598, mean age [standard deviation] at vaccination of 45.5 [23.3] years and 43.2 [25.5] years, 55% female) the RR of developing ON was 0.44 (95% CI, 0.28-0.80). The first dose of COVID-19 and Tdap vaccinations (n = 797 538, mean age 38.9 [20.0] years, 54.2% female) cohort had 10 and 16 patients develop ON (RR, 0.63; 95% CI, 0.28-1.38). Comparison of COVID-19-vaccinated patients (n = 3 698 848, 48.2 [21.5] years, 54.7% female) to unvaccinated and COVID-19-infected patients (n = 3 698 848, 49.6 [22.0] years, 55.2% female) showed 49 and 506 patients developing ON, respectively (RR, 0.09; 95% CI, 0.07-0.12). The incidence per 100 000 for ON was 1 in the first dose COVID-19 vaccine cohort, 2 in the influenza cohort, and 2 in the Tdap cohort, and 14 in the COVID-19-infected and unvaccinated cohorts. CONCLUSIONS: Risk of ON after mRNA COVID-19 vaccination is rare and comparable to Tdap vaccination, decreased compared with influenza vaccination, and decreased compared with COVID-19 infection in the absence of vaccination.

Bacillary Layer Detachment in Neovascular Age-Related Macular Degeneration from a Phase III Clinical Trial.

OBJECTIVE: To evaluate the incidence of bacillary layer detachment in patients with neovascular age-related macular degeneration (nAMD) and their response to anti-VEGF therapy. DESIGN: Post hoc analysis of the brolucizumab 6-mg and aflibercept 2-mg arms from the HAWK clinical trial, a 48-week, prospective, double-masked, phase III trial. PARTICIPANTS: Participants (n = 652 and 652 eyes) randomized to brolucizumab 6-mg and aflibercept 2-mg arms from HAWK (NCT02307682). METHODS: Spectral-domain OCT scans were obtained at 4-week intervals throughout the HAWK trial and segmented automatically using a proprietary, machine learning-enabled, higher-order feature extraction platform. MAIN OUTCOME MEASURES: The incidence of bacillary layer detachment and effect of anti-VEGF therapy in these eyes on best-corrected visual acuity (BCVA), central subfield thickness (CST), retinal fluid volumes, subretinal hyper-reflective material (SHRM) volume, and ellipsoid zone (EZ) integrity from baseline to week 48. RESULTS: Classic bacillary layer detachment was identified in 7.2% (47/652) of eyes, demonstrating worse BCVA and higher CST, EZ total attenuation, subretinal fluid (SRF), and SHRM volume at baseline than eyes without bacillary layer detachment. Anti-VEGF treatment resulted in resolution of bacillary layer detachment in 97.9% of eyes by week 48. In eyes with bacillary layer detachment, anti-VEGF treatment improved BCVA and decreased SRF and SHRM volume; however, eyes with bacillary layer detachment never reached the level of BCVA improvement as eyes without bacillary layer detachment. A greater proportion of eyes with bacillary layer detachment had high-exudative volatility (increased mean standard deviation after loading dose) of CST, SRF, and total fluid than eyes without bacillary layer detachment (P < 0.05 for each comparison). CONCLUSIONS: Bacillary layer detachment, an OCT signature representing photoreceptor schisis, is identifiable in a notable proportion of eyes with nAMD. Anti-VEGF therapy resulted in a very high proportion of bacillary layer detachment resolution with significantly decreased SRF and SHRM volumes. The majority of eyes with bacillary layer detachment have high-exudative volatility, which may be associated with lower BCVA outcomes. The presence of bacillary layer detachment may provide an important imaging biomarker to be considered for clinical trial inclusion/exclusion based on trial design and therapeutic goals because of its unique behavior.

Characterizing the Journey of Geographic Atrophy Patients in Routine Ophthalmic Practice.

BACKGROUND AND OBJECTIVE: Geographic atrophy (GA) is a form of late-stage age-related macular degeneration (AMD). This study aims to characterize the journey of patients with GA in real-world ophthalmology practice. PATIENTS AND METHODS: This is a retrospective cohort study of 100 patients with GA and 100 with intermediate AMD (iAMD). RESULTS: Approximately one-third of GA patients' eyes had GA at the time of their initial AMD diagnosis, and nearly half of the iAMD patients' eyes had iAMD at that time. When holding confounders constant, GA patients experienced significantly worse visual acuity outcomes, and a significantly higher proportion required referrals for low vision evaluation, needed assistance for activities of daily living, failed to meet driving standards, and met criteria for legal blindness when compared to iAMD controls. CONCLUSIONS: Many patients have already progressed to GA by the time they receive an AMD diagnosis, emphasizing the importance of providing early detection and intervention, especially considering novel treatment options.

Propensity-Matched Analysis of the Risk of Age-Related Macular Degeneration with Systemic Immune-Mediated Inflammatory Disease.

PURPOSE: The pathogenesis of age-related macular degeneration (AMD) involves aberrant complement activation and is a leading cause of vision loss worldwide. Complement aberrations are also implicated in many systemic immune-mediated inflammatory diseases (IMIDs), but the relationship between AMD and these conditions remains undescribed. The aim of this study is to first assess the association between AMD and IMIDs, and then assess the risk of AMD in patients with specific IMIDs associated with AMD. DESIGN: Cross-sectional study and cohort study. SUBJECTS AND CONTROLS: Patients with AMD were compared with control patients with cataracts and no AMD to ensure evaluation by an ophthalmologist. Patients with IMIDs were compared with patients without IMIDs but with cataracts. METHODS: This study used deidentified data from a national database (2006-2023), using International Classification of Diseases 10 codes to select for IMIDs. Propensity score matching was based on patients on age, sex, race, ethnicity, and smoking. Odds ratios were generated for IMIDs and compared between AMD and control patients. For IMIDs associated with AMD, the risk of AMD in patients with the IMID versus patients without IMIDs was determined utilizing a cohort study design. MAIN OUTCOME MEASURES: Odds ratio of IMID, risk ratios (RRs), and 95% confidence intervals (CIs) of AMD diagnosis, given an IMID. RESULTS: After propensity score matching, AMD and control cohorts (n = 217 197 each) had a mean ± standard deviation age of 74.7 ± 10.4 years, were 56% female, and 9% of patients smoked. Age-related macular degeneration showed associations with systemic lupus erythematosus (SLE), Crohn's disease, ulcerative colitis, rheumatoid arthritis (RA), psoriasis, sarcoidosis, scleroderma, giant cell arteritis, and vasculitis. Cohorts for each positively associated IMID were created and matched to control cohorts with no IMID history. Patients with RA (RR, 1.40; 95% CI, 1.30-1.49), SLE (RR, 1.73; 95% CI, 1.37-2.18), Crohn's disease (RR, 1.42; 95% CI, 1.20-1.71), ulcerative colitis (RR, 1.45; 95% CI, 1.29-1.63), psoriasis (RR, 1.48; 95% CI, 1.37-1.60), vasculitis (RR, 1.48; 95% CI, 1.33-1.64), scleroderma (RR, 1.65; 95% CI, 1.35-2.02), and sarcoidosis (RR, 1.42; 95% CI, 1.24-1.62) showed a higher risk of developing AMD compared with controls. CONCLUSIONS: The results suggest that there is an increased risk of developing AMD in patients with RA, SLE, Crohn's disease, ulcerative colitis, psoriasis, vasculitis, scleroderma, and sarcoidosis compared with patients with no IMIDs.

Visual acuity changes in the preoperative period in patients undergoing cataract surgery.

OBJECTIVE: This study quantifies change in best visual acuity (BVA) over the preoperative period and assesses factors associated with postoperative outcomes. DESIGN: Retrospective chart review conducted at a single institution. PARTICIPANTS: A total of 691 patients underwent cataract surgery and had a preoperative assessment 0-30 days prior to surgery following their surgical evaluation. METHODS: Baseline demographics and past medical and clinical data were collected through electronic medical record query. BVA was noted at initial surgical evaluation, preoperative assessment, and nearest postoperative assessment. RESULTS: A total of 691 patients (911 eyes) were included with mean BVAs at the initial evaluation, preoperative assessment, and postoperative assessment of 68.3 ± 16.8, 64.6 ± 18.5, and 81.1 ± 12.0 ETDRS letters, respectively. Mean BVA was significantly higher postoperatively compared with the preoperative assessment and initial evaluation (p < 0.0001). There was a mean of 53.8 days between initial surgical evaluation and surgery date and a mean of 49.9 days between the preoperative assessment and initial surgical evaluation. The mean interval between the preoperative assessment and surgery was 11.7 days. In the preoperative period, 9.1% of eyes experienced worsening of BVA by >3 eyes and 0.9% experienced improvement of BVA by >3 lines. Time to surgery was significantly associated with change in postoperative BVA (effect size, -0.03 ETDRS letters; p = 0.015) but was not significant on multiple linear regression. BVA at initial evaluation, glaucoma, and glaucoma surgery were all significantly associated with postoperative outcomes. CONCLUSION: Most eyes experienced stable vision in the preoperative period for cataract surgery. On average, patients with high BVAs at the time of initial surgical evaluation may be able to defer surgery without the risk of poorer surgical outcomes.

Deep learning-based algorithm for the detection of idiopathic full thickness macular holes in spectral domain optical coherence tomography.

BACKGROUND: Automated identification of spectral domain optical coherence tomography (SD-OCT) features can improve retina clinic workflow efficiency as they are able to detect pathologic findings. The purpose of this study was to test a deep learning (DL)-based algorithm for the identification of Idiopathic Full Thickness Macular Hole (IFTMH) features and stages of severity in SD-OCT B-scans. METHODS: In this cross-sectional study, subjects solely diagnosed with either IFTMH or Posterior Vitreous Detachment (PVD) were identified excluding secondary causes of macular holes, any concurrent maculopathies, or incomplete records. SD-OCT scans (512 × 128) from all subjects were acquired with CIRRUS™ HD-OCT (ZEISS, Dublin, CA) and reviewed for quality. In order to establish a ground truth classification, each SD-OCT B-scan was labeled by two trained graders and adjudicated by a retina specialist when applicable. Two test sets were built based on different gold-standard classification methods. The sensitivity, specificity and accuracy of the algorithm to identify IFTMH features in SD-OCT B-scans were determined. Spearman's correlation was run to examine if the algorithm's probability score was associated with the severity stages of IFTMH. RESULTS: Six hundred and one SD-OCT cube scans from 601 subjects (299 with IFTMH and 302 with PVD) were used. A total of 76,928 individual SD-OCT B-scans were labeled gradable by the algorithm and yielded an accuracy of 88.5% (test set 1, 33,024 B-scans) and 91.4% (test set 2, 43,904 B-scans) in identifying SD-OCT features of IFTMHs. A Spearman's correlation coefficient of 0.15 was achieved between the algorithm's probability score and the stages of the 299 (47 [15.7%] stage 2, 56 [18.7%] stage 3 and 196 [65.6%] stage 4) IFTMHs cubes studied. CONCLUSIONS: The DL-based algorithm was able to accurately detect IFTMHs features on individual SD-OCT B-scans in both test sets. However, there was a low correlation between the algorithm's probability score and IFTMH severity stages. The algorithm may serve as a clinical decision support tool that assists with the identification of IFTMHs. Further training is necessary for the algorithm to identify stages of IFTMHs.

Long-Term Visual Outcomes in Patients With Idiopathic Epiretinal Membrane Surgery.

BACKGROUND AND OBJECTIVE: Our aim was to assess long-term outcomes following surgical repair of idiopathic epiretinal membrane (ERM) with pars plana vitrectomy (PPV) and membrane peel (MP). PATIENTS AND METHODS: A retrospective study evaluated patients with idiopathic ERM who underwent surgical repair at a single academic tertiary center with five to nine years of postoperative follow-up, assessing preoperative characteristics, surgical techniques, best visual acuity (BVA), and optical coherence tomography biomarkers at various time points. RESULTS: The study involved 67 patients (72 eyes) with an average postoperative follow-up of 82.8 ± 18.8 months. Patients with cone outer segment tips integrity at initial presentation and 1-year follow-up and patients with external limiting membrane and ellipsoid zone integrity at 1-year follow-up were noted to have significantly better long-term visual acuity than those without. More than 85% of patients achieved a BVA > 70 seven years after surgical repair. CONCLUSIONS: Vitreoretinal surgery for idiopathic ERM resulted in improved anatomical recovery and sustained visual acuity gain over long-term follow-up.

Changes in Prevalence of Idiopathic Intracranial Hypertension in the United States Between 2015 and 2022, Stratified by Sex, Race, and Ethnicity.

BACKGROUND AND OBJECTIVES: With the obesity epidemic within the United States, the prevalence of idiopathic intracranial hypertension (IIH) is predicted to rise. IIH prevalence and racial disparities have rarely been reported in the United States. The purpose of this study was to evaluate the prevalence of IIH in a large national database while stratifying by sex, age, race, and ethnicity. METHODS: This was a cross-sectional epidemiologic evaluation conducted in the TriNetX US Collaborative network using data from 2015 to 2022. Patients with an International Classification of Diseases code of IIH and papilledema or unspecified papilledema were included in the study. Any secondary cause of intracranial hypertension including cerebral neoplasms and hydrocephalus were excluded from the study. IIH trends were later compared with TriNetX cohort obesity trends. Prevalence and prevalence odds ratios (ORs) were calculated in Microsoft Excel and R Studio. RESULTS: Among 85 million patients in this database, a 1.35 times increase in the prevalence of IIH occurred between 2015 and 2022 from 7.3 (95% CI 6.9-7.7) individuals per 100,000 to 9.9 (95% CI 9.5-10.3) individuals per 100,000 in 2022. In 2022, Black female individuals had the highest prevalence of IIH with 22.7 individuals per 100,000 compared with the 13.7 White female individuals per 100,000. Patients aged 11-17 years showed the largest growth of IIH prevalence with female individuals increasing by 10 individuals per 100,000 by 2022. Overall, Black and Hispanic patients had the largest prevalence OR of IIH at 1.66 (95% CI 1.49-1.85) and 1.33 (95% CI 1.14-1.56), respectively, compared with White female patients. DISCUSSION: IIH is a rapidly increasing health care concern for the US population, particularly among adolescent patients. Black and Hispanic female individuals are most predominately affected by this incapacitating disorder.

Short-Term Outcomes of Faricimab in Patients with Neovascular Age-Related Macular Degeneration on Prior Anti-VEGF Therapy.

PURPOSE: A subset of patients with neovascular age-related macular degeneration (nAMD) experience treatment burden and suboptimal response with anti-VEGF therapy. The aim of this study was to investigate the effect of switching to a novel, bispecific agent, faricimab, in patients with nAMD currently treated with anti-VEGF. DESIGN: Retrospective, noncomparative cohort study. SUBJECTS: Patients with nAMD previously treated with anti-VEGF and switched to intravitreal faricimab injection (IFI) at the Cleveland Clinic's Cole Eye Institute. METHODS: Switching and administration schedule of IFI was at the discretion of the clinician. Visual acuity (VA) and macular OCT parameters, including central subfield thickness (CST), maximum pigment epithelial detachment (PED) height, and presence of subretinal (SRF) or intraretinal fluid (IRF), were assessed at baseline (day of first IFI) and after each IFI. MAIN OUTCOME MEASURES: Central subfield thickness and presence of IRF or SRF after ≥ 3 IFIs. RESULTS: One hundred twenty-six eyes of 106 patients were included in the analysis with a mean follow-up time of 24.3 ± 5.2 weeks. Before switching to IFI, patients received a mean of either aflibercept (20.0 ± 8.4, mean ± standard deviation), bevacizumab (7 ± 8.9), ranibizumab (1.9 ± 8.5), or brolucizumab (0.3 ± 1.6) injections. The most common agent used before switching to IFI was aflibercept (n = 110, 87%), and the mean treatment interval with any anti-VEGF was 5.6 ± 1.6 weeks before switching. Central subfield thickness was reduced from baseline after the first IFI (266.8 ± 64.7 vs. 249.8 ± 58.6 µm, P = 0.02) and persisted over the 3 IFIs (P = 0.01). Pigment epithelial detachment height was reduced after the third IFI (249.6 ± 179.0 vs. 206.9 ± 130.0 µm, P = 0.01). The mean VA (62.9 vs. 62.7 approximate ETDRS letters, P = 0.42) and interval between injections (6.3 vs. 5.7 weeks, P = 0.16) was similar after the third IFI compared with baseline. Eleven (8.7%) eyes were switched back to their previous anti-VEGF, including 2 (1.6%) eyes from 1 patient with intraocular inflammation requiring cessation of IFI. There were no other adverse events from switching. CONCLUSIONS: Switching to faricimab resulted in a reduction in mean CST (-11.6 µm, P = 0.01) and PED height (-44.2 µm, P = 0.01) after 3 injections, with stable VA and at a similar treatment interval to prior anti-VEGF therapy.

Impact of Dyslipidemia Medications on the Prevalence of Diabetic Retinopathy Among a Large US Cohort.

BACKGROUND AND OBJECTIVE: Dyslipidemia medications such as statins and fibrates may be associated with a reduction in diabetic retinopathy (DR) progression, but real-world data is lacking. This study evaluates cholesterol-lowering medications and their association with the prevalence of DR and advanced DR complications. PATIENTS AND METHODS: Data was collected using codes from the International Classification of Diseases on TriNetX, a cross-sectional database of over 79 million Americans, between June and August 2022. Prevalence and prevalence odds ratios (POR) were calculated. RESULTS: Patients taking pitavastatin (OR 0.64, 95% CI 0.49, 0.84), fenofibrate (OR 0.83, CI 0.79, 0.87), or evolocumab (OR 0.80, CI 0.68, 0.95) had lower POR of proliferative DR compared to nonproliferative DR. Patients taking any cholesterol medication had a lower POR of vitreous hemorrhage. Patients taking fibrates also had lower POR of neovascular glaucoma. CONCLUSION: This exploratory study highlights positive associations between DR and dyslipidemia and medications that may have fewer worsening events in DR patients.
