Identifying Medical Diagnoses and Treatable Diseases by Image-Based Deep Learning.

The implementation of clinical-decision support algorithms for medical imaging faces challenges with reliability and interpretability. Here, we establish a diagnostic tool based on a deep-learning framework for the screening of patients with common treatable blinding retinal diseases. Our framework utilizes transfer learning, which trains a neural network with a fraction of the data of conventional approaches. Applying this approach to a dataset of optical coherence tomography images, we demonstrate performance comparable to that of human experts in classifying age-related macular degeneration and diabetic macular edema. We also provide a more transparent and interpretable diagnosis by highlighting the regions recognized by the neural network. We further demonstrate the general applicability of our AI system for diagnosis of pediatric pneumonia using chest X-ray images. This tool may ultimately aid in expediting the diagnosis and referral of these treatable conditions, thereby facilitating earlier treatment, resulting in improved clinical outcomes. VIDEO ABSTRACT.

Patient Satisfaction in the Era of COVID-19: Virtual Visit versus In-person Visit Satisfaction.

SIGNIFICANCE: Teleophthalmology became widely used during the coronavirus 2019 pandemic; however, the quality of this care remains to be understood. PURPOSE: This study aimed to compare patient satisfaction levels from virtual and in-person visits based on post-visit surveys, as well as investigate demographic characteristics that may predict patient satisfaction with virtual visits. METHODS: Virtual (n = 2943) and in-person (n = 56,175) visits from March 19, 2020, to July 31, 2020, were identified using the electronic health record system. For in-person visits, a random subset of 3000 visits was acquired using a random number generator. Of these, 2266 virtual and 2590 in-person visits met the inclusion criteria. Patients who completed the Telemedicine for Medical Practice Survey and Medical Practice Survey were analyzed in this report. Nonparametric Mann-Whitney test was used to compare scores between groups. RESULTS: Two hundred eleven virtual patients (9.31%; 82 phone, 115 video, 14 hybrid) and 307 in-person patients (11.85%) completed the Telemedicine for Medical Practice Survey and Medical Practice Survey, respectively. Satisfaction scores were similar and high in both groups-virtual visit satisfaction scores averaged 4.82, whereas in-person visit satisfaction averaged 4.85 (P = .80, θ = 0.501 [0.493 to 0.509]). Only one question yielded significantly different satisfaction scores, and no demographic variables were significant predictors of satisfaction scores. CONCLUSIONS: Patient satisfaction is comparable between virtual and in-person visits, validating the continued usage of telemedicine for eye care visits.

Photobiomodulation therapy in age-related macular degeneration.

PURPOSE OF REVIEW: To review the available data supporting the use of photobiomodulation therapy (PBT) in the treatment of age-related macular degeneration (AMD). RECENT FINDINGS: PBT might be used in treating nonexudative AMD. Limited evidence suggests that exudative AMD may also benefit from PBT. SUMMARY: The optimal device would deliver doses of 60 J/cm2 or more with a multiwavelength composition through the pupil over short treatment intervals. Safe upper limits have not been established. More studies are needed to evaluate the efficacy of PBT in treating exudative and nonexudative AMD.

Evidence for the Hepato-Retinal Axis: A Systematic Review.

BACKGROUND AND OBJECTIVE: Liver health has been reported to be associated with retinal pathology in various ways. These include deposition of retino-toxins, neovascular drive, and disruption of the blood-retina barrier. Extrahepatic synthesis of implicated molecules and hemodynamic changes in liver dysfunction are also considered. The objective was to review the current evidence for and against a hepato-retinal axis that may guide further areas of preclinical and clinical investigation. METHODS: This was a systematic review. PubMed and Cochrane were queried for English language studies examining the connection between hepatic dysfunction and retinal pathology. RESULTS: Fourteen studies were included and examined out of 604 candidate publications. The studies selected include preclinical studies as well as clinical case series and studies. CONCLUSIONS: Several liver pathologies may be linked to retinal pathology as mediated by hepatically synthesized molecules. The hepato-retinal axis may be present and further, targeted studies of the axis are warranted. [Ophthalmic Surg Lasers Imaging Retina 2024;55:587-596.].

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.

Macular Thickness Fluctuations in Eyes With Diabetic Macular Edema Treated With Intravitreal Steroid.

BACKGROUND AND OBJECTIVE: Macular thickness fluctuations (MTF) over time may be more predictive of visual outcomes than absolute macular thickness in patients with diabetic macular edema (DME) treated with anti-vascular endothelial growth factor (anti-VEGF). It is unclear whether this association exists in DME patients treated with intravitreal steroids or whether steroids confer reduced MTF versus anti-VEGF treatments. PATIENTS AND METHODS: MTF was compared before and after initiation of steroids in DME patients treated with intravitreal steroids. A mixed-effects linear regression model was used to determine the association between MTF and best-corrected visual acuity (BCVA). RESULTS: Mean 12-month MTF significantly decreased after steroid initiation (61.1 µm versus 53.5 µm, P = 0.04, n = 105 eyes). Mean BCVA after 12 months was not significantly different from baseline. No significant association between post-steroid MTF and 12-month BCVA was found. CONCLUSION: Steroid treatment decreases MTF while BCVA remains stable in DME patients previously treated with anti-VEGF. [Ophthalmic Surg Lasers Imaging Retina 2023;54:454-460.].

Time to Resolution of Diabetic Macular Edema after Treatment with Intravitreal Aflibercept Injection or Laser in VISTA and VIVID.

OBJECTIVE: To assess the relationship between baseline factors and time to diabetic macular edema (DME) resolution. DESIGN: Post hoc analysis of VISTA and VIVID. PARTICIPANTS: Eyes with baseline central subfield thickness (CST) of ≥ 290 µm. INTERVENTION: Eyes were treated with intravitreal aflibercept injection (IAI) 2 mg (n = 558; every 4 weeks or every 8 weeks after 5 monthly doses) or laser control (n = 274). The effect of baseline factors on the time to DME resolution (CST < 290 µm) was assessed in univariable and multivariable models and further evaluated by the Kaplan-Meier method. MAIN OUTCOME MEASURES: Time to and cumulative incidence of DME resolution. RESULTS: Eyes treated with IAI had a 2.5-fold higher DME resolution rate, with median time of 33.0 weeks (95% confidence interval [CI], 28.1-40.0), compared with DME resolution not being achieved in 50% of eyes treated with laser control. Multivariable analysis demonstrated that a lower DME resolution rate was associated with a thicker baseline CST (hazard ratio [HR] [95% CI] per 100-µm CST increase, 0.79 [0.72-0.86]) and better baseline best-corrected visual acuity (BCVA) (HR [95% CI] per 5-letter increase, 0.87 [0.83-0.92]) with IAI. Tertiles of increasing CST (T1CST ≤ 419 µm; T2CST > 419 to ≤ 541; T3CST > 541) were associated with longer median times to DME resolution (20.1, 39.1, and 49.1 weeks, respectively; P < 0.001 for T2CST and T3CST versus T1CST) and lower cumulative incidence of events (HR, 1.0, 0.6, and 0.6, respectively; P < 0.001 for T2CST and T3CST versus T1CST) with IAI. Tertiles of increasing BCVA (T1BCVA ≤ 57 letters; T2BCVA > 57 to ≤ 66; T3BCVA >66) were associated with longer median times to DME resolution (28.4, 31.7, and 44.1 weeks, respectively; P < 0.05 for T3BCVA versus T1BCVA) and lower cumulative incidence of events (HR, 1.0, 0.9, and 0.8, respectively; P < 0.05 for T3BCVA versus T1BCVA) with IAI. No other baseline factor was associated with the time to DME resolution. CONCLUSIONS: The median time to DME resolution was 33 weeks among IAI-treated eyes. A thicker baseline CST and better baseline BCVA in the IAI group were associated with a longer time to and a lower rate of DME resolution.

Baseline Diabetic Retinopathy Severity and Time to Diabetic Macular Edema Resolution with Ranibizumab Treatment: A Meta-Analysis.

OBJECTIVE: Having a better understanding of how long diabetic macular edema (DME) takes to resolve in patients with diabetic retinopathy (DR) after treatment with ranibizumab, and the factors affecting this outcome, would be of benefit to physicians and patients alike. The objective of this analysis was to evaluate the time to first DME resolution and the impact of baseline DR severity on this outcome in patients treated with ranibizumab in phase III clinical trials. DESIGN: Meta-analysis of data from the phase III trials, RIDE (NCT00473382) and RISE (NCT00473330), and DR Clinical Research Network protocols I (NCT00444600), S (NCT01489189), and T (NCT01627249). PARTICIPANTS: Patients with DME (central subfield thickness [CST] > 250 µm) and DR with Diabetic Retinopathy Severity Scale (DRSS) score between 35 and 85. INTERVENTION: Intravitreal injection of ranibizumab. MAIN OUTCOME MEASURES: The time to first DME resolution (defined as CST ≤ 250 µm) within 24 months was evaluated overall and by baseline DR severity category per the DRSS (35 of 43 [mild or moderate nonproliferative DR], 47-53 [moderately severe or severe nonproliferative DR], 60 [mild proliferative DR], and 61-85 [moderately severe to severe proliferative DR]). RESULTS: There were 777 patients included in the meta-analysis. The overall mean (95% confidence interval) time to first DME resolution, adjusted for baseline CST, was 6.0 (5.6-6.4) months. The mean (95% CI) time to first DME resolution was 7.1 (6.2-7.9), 5.9 (5.2-6.6), 6.0 (4.8-7.2), and 4.5 (3.5-5.5) months for the 35 of 43, 47 to 53, 60, and 61 to 85 baseline DRSS categories, respectively (overall P = 0.002). By month 24, the proportion of eyes with DME resolution was 74.9% (221 of 295), 77.5% (299 of 386), 69.4% (109 of 157), and 78.7% (148 of 188) for the 35 of 43, 47 to 53, 60, and 61 to 85 baseline DRSS categories, respectively (overall P = 0.17). CONCLUSIONS: This meta-analysis of data from patients treated with ranibizumab showed that DME resolution was faster in patients with more severe DR at baseline. However, by month 24, a similar proportion of patients achieved DME resolution, regardless of baseline DR severity. These findings may guide treatment decisions and inform patient expectations in clinical practice. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

Baseline factors and reason for cancellation of elective ophthalmic surgery.

OBJECTIVES: To determine the baseline risk factors for elective ophthalmic surgery cancellations and characterise the reasons for cancellation. METHODS: This is a retrospective, non-randomised study performed at a large tertiary ophthalmic centre. It included a consecutive sample of patients above the age of 18 who had an ophthalmic surgery scheduled at Cole Eye Institute, Cleveland Clinic, OH between January 2012 and December 2019. An automated search pull identified 75,908 scheduled surgeries (63,987 completed and 11,921 cancelled surgeries). Statistical analysis was performed using R (version 3.5.1). Main outcome measures were baseline factors that impact risk for surgery cancellation and reasons for surgery cancellation. RESULTS: Analysis was performed on 69,963 scheduled surgeries (57.37% Female, 42.63% Male; Mean age of 62.72 years; 59,959 completed and 10,004 cancelled surgeries). Of the 2384 cancelled surgeries with reasons provided, the most common causes of cancellation were patient refusal (38.42%), patient health condition (18.79%), and rescheduling of surgery (15.27%). Female sex, black race, patient age less than 50 years, non-cataract surgeries, regional mean household income greater than $82,900, Medicare insurance, and geographical distance of less than 10 miles from home to the surgery site were each associated with a significantly increased risk of surgery cancellation (p < 0.01). CONCLUSIONS: This study successfully identified several baseline factors predicting elective ophthalmic surgery cancellation. The clinical insights gained from these lines of enquiry may be used to construct models that not only identify patients at greater risk for cancellation but also highlight which interventions have greatest efficacy in preventing ophthalmic surgery cancellations.

Perioperative COVID-19 Screening at a Tertiary Ophthalmic Institution.

Purpose: To characterize the rate of COVID-19 positivity during presurgical screening and the surgical outcomes of ophthalmic patients who were positive for COVID-19 and to report the overall cost. Methods: This retrospective study included patients 18 years or older who had ophthalmic surgical procedures at a tertiary institution between May 11, 2020, and December 31, 2020. Patients without a valid presurgical COVID-19 test within 3 days before their scheduled procedure, who had incomplete or mislabeled visits, or who had incomplete or missing data in their file were excluded. COVID-19 screening was completed using a polymerase chain reaction (PCR) kit. Results: Of the 3585 patients who met the inclusion criteria, 2044 (57.02%) were women; the mean age was 68.2 years ± 12.8 (SD). Thirteen asymptomatic patients (0.36%) tested positive for COVID-19 via PCR screening. Three patients had a known positive COVID-19 infection within the 90 days before surgery; thus, 10 patients (0.28%) were found to have asymptomatic naïve COVID-19 infection via PCR testing. Testing was associated with a total charge of US $800 000. Five of the 13 patients (38.46%) who tested positive for COVID-19 experienced a delay in their surgery; the mean delay was 17.23 ± 22.97 days. Conclusions: Asymptomatic ophthalmic surgical patients had a low positivity rate with a limited impact on surgery scheduling at a significant cost. Further studies would be valuable in evaluating a targeted presurgical screening population as opposed to universal testing.

Outcomes in patients with retinal vein occlusion with good baseline visual acuity.

BACKGROUND: Intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) are first-line therapy for macular oedema in retinal vein occlusion (RVO). Appropriate management for RVO with good visual acuity at diagnosis has not been evaluated. The purpose of this study is to analyse the visual and anatomic outcomes from anti-VEGF treatment among RVO patients with good vision at baseline. METHODS: This retrospective cohort study evaluated patients diagnosed with macular oedema secondary to RVO from January 2012 to February 2021 at a tertiary ophthalmic centre. Patients had a Snellen acuity of 20/32 or better at diagnosis. Three cohorts were compared: patients with no anti-VEGF treatment, delayed anti-VEGF treatment (initial injection >30 days post-diagnosis) and immediate anti-VEGF treatment (initial injection ≤30 days post-diagnosis). Central subfield thickness (CST) and best visual acuity (BVA) were collected at diagnosis and 6-, 12- and 24-month follow-up appointments. RESULTS: Among 131 eyes, mean BVA values among treatment groups did not differ at 6-, 12- or 24-month follow up visits (P = 0.521, 0.426, 0.356, respectively). The percentage of eyes with at least a 5-letter BVA decrease at 24 months was 24.1%, 65.0% and 30.8% in the no treatment, delayed and immediate treatment groups respectively (P = 0.010). There was no significant difference in the percentage of eyes with at least a 10% decrease in CST at 24 months among groups (P = 0.095). CONCLUSIONS: Close observation with initiation of treatment in patients with good visual acuity with macular oedema secondary to RVO as indicated has similar outcomes in the setting of routine clinical practice.

Meta-Analyses of Two Treatment Regimens for Retinal Vein Occlusion.

BACKGROUND AND OBJECTIVES: To pool available data on the change in best-corrected visual acuity (BCVA), central retinal thickness (CRT), and number of injections as reported by treat and extend (T&E) and pro re nata (PRN) regimens for retinal vein occlusion (RVO). MATERIALS AND METHODS: After PubMed was queried, separate random effect models were fitted to the data extracted and the Wald test was used to compare the estimates of the two independent meta-analyses. RESULTS: Fourteen T&E and 29 PRN studies were included in two independent meta-analyses. No significant difference was observed in BCVA (+14.74 [+11.52, +17.96] in T&E vs +15.90 [+14.24, + 17.56] in PRN, P = 0.530) or CRT improvements (-259.56 [-189.02, -330.09] in T&E vs -256.58 [-226.57, -286.48] in PRN, P = 0.939). More injections over 12 months were observed in T&E regimens (7.48 [6.32, 8.65] vs 5.13 [4.20, 6.06] in PRN, P = 0.002). CONCLUSION: Although more injections may be required, T&E achieves similar functional and anatomic benefits as compared to PRN regimens. [Ophthalmic Surg Lasers Imaging Retina 2023;54:244-250.].

Time to fellow eye involvement in patients with unilateral diabetic macular oedema.

OBJECTIVE: To examine the time to onset of disease in the fellow eye of patients with unilateral DMO in routine clinical practice and to identify risk factors for development of bilateral DMO. DESIGN: Retrospective cohort study. PARTICIPANTS: One hundred forty treatment-naive patients 18 years or older with unilateral DMO presenting to Cole Eye Institute between January 2012 and July 2021. METHODS: Records of patients with unilateral DMO were reviewed for development of DMO in the fellow eye. Demographic, diabetic, ocular, and systemic characteristics were collected at initial DMO diagnosis date. Bivariate and multivariate analyses were performed and significant factors were modelled using Kaplan-Meier curves. RESULTS: Fifty patients with conversion to bilateral DMO and 90 patients without conversion were identified. Average time to bilateral DMO was 15.0 ± 15.7 months. 64% of patients converted within 1 year and 90% converted within 3 years. HbA1c (p = 0.003), diabetic retinopathy duration (p = 0.029), and diabetic foot disease (DFD) (p = 0.002) were identified as significant risk factors for conversion. Patients with better visual acuity at time of initial diagnosis and history of panretinal photocoagulation (PRP) (p = 0.044) or focal laser (p = 0.035) in the primary eye were also more likely to convert. CONCLUSIONS: Participants were most likely to develop fellow eye DMO within the first year after initial DMO diagnosis. In routine clinical practice, poor glycaemic control and DFD were risk factors associated with bilateral eye involvement. Clinicians may consider screening the fellow eye of high-risk individuals at each appointment within the first year of diagnosis.

Characterization of ophthalmology virtual visits during the COVID-19 pandemic.

OBJECTIVES: To characterize the use of virtual visits, as well as compare the characteristics to in-person visits during the pandemic period. METHODS: This retrospective study included patients who had virtual and in-person ophthalmology visits from March 19, 2020, to July 31, 2020, in a large multispecialty ophthalmic center. Exclusion criteria included patients aged less than 18 years old; canceled, incomplete, mislabelled, and duplicated visits. 2943 virtual and 56,174 in-person visits were identified. A random sample of 3000 in-person visits was created. Each visit was analyzed as an individual data point. RESULTS: 2,266 virtual visits (2,049 patients, 64.3% female, mean [SD] age 64.3 [16.6] years old) and 2590 in-person visits (2509 patients, 59.5% female, 65.9 [15.8] years old) were included. Most virtual visits were classified as comprehensive ophthalmology (34.6%), optometry-related (19.5%), and oculoplastics (13.0%). For in-person visits, the most common specialties were optometry (29.8%), comprehensive ophthalmology (23.9%), and retina and uveitis (17.3%). The most common diagnoses in the virtual group were from the eyelids, lacrimal system, and orbits group (26.9%), while in the in-person groups were choroid and retina conditions (19.3%). CONCLUSIONS: Numerous ocular conditions were evaluated and managed through virtual visits, and external complaints and oculoplastic consults appear to be well-suited to the virtual format. Further studies focusing on visual outcomes and patient experience will be beneficial.

Functional Imaging of Mitochondria in Age-Related Macular Degeneration Using Flavoprotein Fluorescence.

PURPOSE: Oxidative stress-induced mitochondrial dysfunction is implicated in the pathogenesis of age-related macular degeneration (AMD). Oxidized mitochondrial flavoprotein fluorescence (FPF) may serve as a quantifiable biomarker of oxidative stress, reported as either mean score for the entire image (intensity) or variability (heterogeneity). This study examines FPF intensity and heterogeneity across a large patient cohort of various Beckman stages of AMD. METHODS: This study enrolled patients with isolated AMD and healthy control patients with no retinopathy between 2018 and 2021. Multivariate logistic regression analysis included stage of AMD, age, gender, ethnicity, and smoking status. Analysis of Variance test compared mean FPF intensity and heterogeneity between disease states. RESULTS: Four hundred fifty-six eyes (228 AMD eyes, 228 age-matched control eyes) were included in the final multivariate analysis. Intermediate, geographic atrophy (GA), and neovascular AMD correlated with significantly increased FPF intensity (P < 0.001, respectively), while all AMD stages correlated with increased FPF heterogeneity (P < 0.001, respectively). FPF intensity and heterogeneity were significant negative predictors of visual acuity (P = 0.018 and 0.024, respectively). CONCLUSIONS: This prospective observational study further implicates mitochondrial damage in AMD pathophysiology. Long-term clinical trials will be needed to examine the predictive role of FPF imaging in patients over time. [Ophthalmic Surg Lasers Imaging Retina 2023;54:24-31.].

The Impact of Travel Distance on Rhegmatogenous Retinal Detachment Presentation and Outcomes.

BACKGROUND AND OBJECTIVE: Rhegmatogenous retinal detachment (RRD) requires urgent surgical intervention. The effect of travel distance on RRD outcomes is unclear. PATIENTS AND METHODS: This retrospective cohort study included 642 patients who underwent RRD repair at Cole Eye Institute from 2012 to 2020. Google Maps was used to calculate the travel distance in miles from the residential zip code to the presenting and surgery location addresses. Multivariable logistic and bivariate linear regressions were used to compare macula-off status and best-corrected visual acuity (BCVA) in ETDRS letters at presentation and at 6-month follow-up, with patient travel distance divided into < 25 miles, 25 to 50 miles, and > 50 miles. RESULTS: Four hundred sixty-two patients were examined in the final cohort. The retinal reattachment rate was 94.3% for less than 25 miles, 96.3% for 25 to 50 miles, and 95.9% for greater than 50 miles (P = 0.63). In multivariable analysis, distance to presenting location was not associated with macula-off status (P = 0.69) or BCVA at follow-up (P = 0.27). Oneway analysis of distance and time from presentation to surgery in days revealed that distance to surgical site was associated with longer time to surgery (P = 0.003). Subset analysis of patients with income less than $25,520 (n = 18) revealed greater distance to presenting and surgical location was associated with longer time to surgery (P < .0001), but was not associated with BCVA at follow-up (P = 0.53). CONCLUSIONS: This data suggests that patients who live further from the hospital achieve equivalent outcomes from RRD repair, despite delays in surgery.

Rhegmatogenous Retinal Detachment: Variations in Clinical Presentation and Surgical Outcomes by Socioeconomic Status and Race.

BACKGROUND AND OBJECTIVE: To characterize rhegmatogenous retinal detachment (RRD) presentation and repair outcomes by race and socioeconomic status. MATERIALS AND METHODS: Retrospective cohort one-center study of adults with a new RRD repair from 2012 to 2020. Logistic and linear regression analyses were conducted. RESULTS: 61.7% were male, 84.5% White and 9.4% Black (total n = 1092). 95.8% White and 94.2% Black patients had retinal reattachment (P = .234). Macula-off status was more likely with Medicare/Medicaid than private insurance (OR 1.63, 95% CI 1.11 to 2.41, P = .014); and less likely with higher income (OR 0.88, CI 0.81 to 0.96, P = .003). Black patients had worse best visual acuity (BVA) at presentation and follow-up (follow-up -6.93 letters, CI -13.19 to -0.64, P = .031), and higher odds of postoperative ocular hypertension (OHTN) (OR 2.41, CI 1.28 to 4.60, P = .007). CONCLUSIONS: Despite equivalent retinal reattachment rates, Black patients have worse BVA, and are more likely to develop OHTN than White patients. Macula-off status is less likely in patients with higher income or private insurance. [Ophthalmic Surg Lasers Imaging Retina 2022;53:538-545.].

Evaluation of the Content of Ophthalmology Fellowship Program Web sites.

Purpose To assess the availability and content of fellowship program Web sites (FPWs) among ophthalmology subspecialties. Design This is a cross-sectional study. Subjects Web sites of all Association of University Professors of Ophthalmology-accredited fellowship programs in five subspecialties (i.e., surgical retina and vitreous; cornea, external disease, and refractive surgery; glaucoma; neuro-ophthalmology; and pediatric ophthalmology). Methods FPWs were assessed for the presence of 26 key content criteria encompassing program demographics ( n = 13), features ( n = 10), and social life ( n = 3). The presence of each content criterion as well as the content criteria groups were compared across subspecialties. Main Outcome Measures The main outcome measured is the average percentage of key content criteria present among ophthalmology fellowship Web sites. Results Among 266 accredited fellowship programs, 240 (90.2%) had Web sites. On average, Web sites reported 14.9 of 26 key content criteria (57.2%), 8.29 of 13 demographic criteria (63.8%), 5.84 of the 10 program features criteria (58.4%), and 0.705 of the 3 social life criteria (23.5%). Significant differences were identified among subspecialties in the presence of program description ( p = 0.046), hospital affiliation ( p < 0.001), names of current fellows ( p = 0.004), case diversity ( p = 0.001), and surgical statistics ( p = 0.015). The average number of key criteria differed between subspecialties ( p < 0.001). Conclusion There is significant heterogeneity in program fellowship Web site content among ophthalmology subspecialties. Information regarding social life, such as wellness programs and community information, was largely absent across all disciplines. Addressing missing information on ophthalmology FPWs may help optimize program-applicant fit.

Anti-Vascular Endothelial Growth Factor Treatment Patterns and Outcomes in Retinal Vein Occlusion in Routine Clinical Practice.

BACKGROUND AND OBJECTIVE: To characterize treatment patterns for retinal vein occlusion (RVO)-related macular edema (ME) in routine clinical practice and its impact on long-term best-corrected visual acuity (BCVA) and central subfield thickness (CST). PATIENTS AND METHODS: Retrospective study of 365 eyes with branch RVO (BRVO) or central/hemi-RVO (CRVO/HRVO)-related ME between 2003 and 2020. Regression analysis identified factors associated with maintenance injection interval (MII). Subgroup analysis compared outcomes between different MIIs. RESULTS: 51.3% of BRVO patients received injections ≤q8 weeks, 26.4% received injections q8-12 weeks, and 22.3% received injections >q12 weeks. 45.2% of CRVO/HRVO patients received injections ≤q8 weeks, 32.1% received injections q8-12 weeks, and 22.6% received injections >q12 weeks. Age, diabetes, and baseline CST were found to predict MII. There was no significant difference in BCVA and CST at baseline, 12, or 24 months in all MII groups in BRVO and CRVO/HRVO. CONCLUSION: There exists a significant heterogeneity in anti-VEGF treatment frequency for RVO-associated ME in routine clinical practice. [Ophthalmic Surg Lasers Imaging Retina 2022;53:626-633.].

Influence of Race, Ethnicity, and Socioeconomic Factors in Idiopathic Macular Hole Presentation and Surgical Outcomes.

BACKGROUND AND OBJECTIVE: To characterize the influence of race, ethnicity, and socioeconomic factors on idiopathic macular hole (IMH) presentation and surgical outcomes. PATIENTS AND METHODS: This retrospective cohort study of patients diagnosed with IMH who underwent surgical repair collected IMH data from optical coherence tomography scans as well as demographic information. Univariate and multivariate regression models interrogated relevant relationships. RESULTS: Of 292 eyes analyzed, 223 (76.4%) patients were White and 53 (18.2%) were Black. Mean income was $57,076.9 ± 17,794.7. Black patients presented with 0.05 mm2 larger IMH area (95% CI, 0.01 to 0.09; P = .01) and 69.07 µm wider minimum linear diameter (95% CI, 15.05 to 123.10; P = .01). Patients with higher income presented with 3.76 µm narrower base diameter (95% CI, -6.42 to -1.09; P = .006). CONCLUSIONS: Black patients were associated with larger IMH at presentation, and higher income patients were associated with smaller IMH. [Ophthalmic Surg Lasers Imaging Retina 2022;53(6): 333-344.].
