The Spectrum of Isolated Retinal Artery Occlusion Secondary to Giant Cell Arteritis.

We systematically reviewed the literature to investigate the clinical features of isolated arteritic retinal artery occlusion (A-RAO) associated with giant cell arteritis (GCA). The four primary types of A-RAO were central retinal artery occlusion (CRAO), hemi-central retinal artery occlusion (hCRAO), branch retinal artery occlusion (BRAO), and cilioretinal artery occlusion (CLRAO). The most reported presentation was unilateral CRAO, followed by bilateral CRAO, unilateral CLRAO, and bilateral BRAO. Most RAOs were accompanied by typical GCA signs and symptoms, which can help distinguish them from non-arteritic RAOs. When reported, temporal artery biopsy confirmed GCA in most cases. Patients with GCA may present with a broad spectrum of isolated unilateral and bilateral A-RAOs. [Ophthalmic Surg Lasers Imaging Retina 2024;55:XX-XX.].

Risk factors for complications in resident-performed cataract surgery: A systematic review.

We assessed risk factors for complications associated with resident-performed cataract surgery. Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines, we searched 4databases in September, 2023. We included peer-reviewed, full-text, English-language articles assessing risk factors for complications in resident performed cataract surgery. We excluded studies describing cataract surgeries performed by fellows, combined surgeries, and studies with insufficient information. Our initial search yielded 6244 articles; 15 articles were included after title/abstract and full-text review. Patient-related risk factors included older age, hypertension, prior vitrectomy, zonular pathology, pseudoexfoliation, poor preoperative visual acuity, small pupils, and selected types of cataracts. Surgeon-related risk factors included resident postgraduate year and surgeon right-handedness. Other risk factors included absence of supervision, long phacoemulsification time, and phacoemulsification with high power and torsion. The quality of the studies was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation; most studies graded as moderate, primarily due to risk of bias. When assigning cases to residents, graduate medical educators should consider general and resident-specific risk factors to facilitate teaching and preserve patient safety.

Retained foreign objects after routine cataract surgery: a systematic review.

PURPOSE: Retained foreign objects (RFOs) can place patients undergoing cataract surgery at risk for significant vision-threatening complications. In this systematic review, we examine the characteristics, clinical outcomes, and management of RFOs originating from surgical instruments or the surgical field after routine cataract surgery. METHODS: Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, we searched five databases in June 2023. The inclusion criteria were peer-reviewed, full-text, English-language articles describing RFOs after routine cataract surgery. Studies that described non-routine cataract surgeries, patients with a history of ocular trauma, or organic RFOs were excluded. Two investigators independently extracted data and appraised the methodological quality of each study using Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). RESULTS: Twenty-eight studies were included in our qualitative synthesis describing metal, fiber, and plastic RFOs. Typically, the RFOs were detected during surgery or slit-lamp examination. Presentations of patients with metal or fiber RFOs varied, with some being asymptomatic. Patients with plastic RFOs were usually symptomatic, often with decreased visual acuity and/or anterior chamber inflammation. Metal RFOs may have originated from metal fatigue from prolonged instrument usage and contact between surgical instruments, fiber RFOs from surgical wipes and gauzes, and plastic RFOs from instrument wrapping and intraocular lens defects. Factors such as location, biocompatibility, and secondary intraocular inflammation influenced the decision to surgically remove RFOs. Following surgical removal, the signs and symptoms resolved in most patients with RFOs. The studies' GRADE ratings indicated limitations in risk of bias and imprecision. CONCLUSION: The presentation and management of RFOs varied depending on the type of material. To prevent RFOs, clinicians should carefully inspect surgical instruments and packs and use fiber-free wipes, towels, and gauzes. Future studies should investigate the efficacy and cost-effectiveness of different RFO prevention strategies.

Patient Surgical Outcomes When Surgery Residents Are the Primary Surgeon by Intensity of Surgical Attending Supervision in Veterans Affairs Medical Centers.

Objective: Using health records from the Department of Veterans Affairs (VA), the largest healthcare training platform in the United States, we estimated independent associations between the intensity of attending supervision of surgical residents and 30-day postoperation patient outcomes. Background: Academic leaders do not agree on the level of autonomy from supervision to grant surgery residents to best prepare them to enter independent practice without risking patient outcomes. Methods: Secondary data came from a national, systematic 1:8 sample of n = 862,425 teaching encounters where residents were listed as primary surgeon at 122 VA medical centers from July 1, 2004, through September 30, 2019. Independent associations between whether attendings had scrubbed or not scrubbed on patient 30-day all-cause mortality, complications, and 30-day readmission were estimated using generalized linear-mixed models. Estimates were tested for any residual confounding biases, robustness to different regression models, stability over time, and validated using moderator and secondary factors analyses. Results: After accounting for potential confounding factors, residents supervised by scrubbed attendings in 733,997 nonemergency surgery encounters had fewer deaths within 30 days of the operation by 14.2% [0.3%, 29.9%], fewer case complications by 7.9% [2.0%, 14.0%], and fewer readmissions by 17.5% [11.2%, 24.2%] than had attendings not scrubbed. Over the 15 study years, scrubbed surgery attendings may have averted an estimated 13,700 deaths, 43,600 cases with complications, and 73,800 readmissions. Conclusions: VA policies on attending surgeon supervision have protected patient safety while allowing residents in selected teaching encounters to have limited autonomy from supervision.

Treatments for Acute Nonarteritic Central Retinal Artery Occlusion: Findings From a Cochrane Systematic Review.

Many interventions for nonarteritic central retinal artery occlusion (CRAO) are associated with serious complications and little effect on visual outcomes. We report on the findings of a Cochrane systematic review that searched seven databases for peer-reviewed articles reporting on treatments for acute nonarteritic CRAO. We assessed six randomized controlled trials, including interventions such as tissue plasminogen activator (t-PA), isovolumic hemodilution, eyeball massage, intraocular pressure reduction, anticoagulation, vasodilation, oxygen inhalation, laser embolysis, transcorneal electrical stimulation, thrombolysis, pentoxifylline, and enhanced external counterpulsation. However, none of the randomized controlled trials demonstrated significant improvement in visual acuity at 1 month compared to observation, and some patients treated with t-PA experienced serious adverse effects including intracranial hemorrhage. Proposed interventions for acute nonarteritic CRAO may not be better than observation, but the evidence is uncertain. Larger, well-designed studies are necessary to determine the most effective management option for acute nonarteritic CRAO. [Ophthalmic Surg Lasers Imaging Retina 2023;54:650-653.].

Gender and Research Productivity of Vitreoretinal Surgery Fellowship Program Directors.

BACKGROUND AND OBJECTIVE: Characteristics of vitreoretinal surgery fellowship program directors (PDs) in North America are not well described. This study reports on the gender and research productivity of vitreoretinal surgery PDs in the United States and Canada. MATERIALS AND METHODS: We reviewed demographics, total number of Scopus-indexed publications, h-index, and m-quotient for vitreoretinal surgery fellowship PDs in 2022. Descriptive statistics, student t-tests, χ2 tests, and logistic regression analyses were performed. RESULTS: Information was obtained on 83/89 (93%) PDs; 86% were male, and 84% did not have an additional graduate degree. The mean publication count was 81.54 (SD: 90.33) and mean h-index was 20.61 (SD: 16.49). There were no significant differences between female and male fellowship PDs with respect to number of publications, h-indices, and m-quotients. CONCLUSION: Women were underrepresented among vitreoretinal fellowship PDs although they had similar research productivity as their male colleagues.

Virtual supervision in ophthalmology: a scoping review.

PURPOSE: The published information on virtual supervision (VS) in ophthalmology is not well described. This scoping review describes the evidence and potential role for VS in ophthalmic practice and education. METHODS: A literature search strategy was developed in accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). We included full-text articles published in an English-language peer-reviewed journal that involved physician-physician or physician-trainee VS in ophthalmology. We excluded studies with direct (in-person) supervision. Two investigators independently extracted from each article the year of publication and study location, design, participant characteristics, sample size, and outcomes. We appraised the methodological quality of the studies using the Mixed Methods Appraisal Tool (MMAT). RESULTS: Seven articles were included in our qualitative synthesis. Supervisees ranged from physicians such as an ophthalmic surgeon and a general practitioner to medical trainees such as ophthalmology residents, vitreoretinal fellows, and emergency medicine residents. Study settings included emergency departments, operating rooms, eye clinics, and a rural hospital. All studies reported successful transmission of real-time images or videos of clinical examinations and surgical or in-office procedures. Various methods were used to ensure high image and video quality during VS, although some technical challenges remained. MMAT ratings revealed limitations in outcome measurement, statistical analysis, sampling strategy, and inclusion of confounding factors. CONCLUSION: Virtual supervision in ophthalmology is technologically feasible and permits synchronous communication and transmission of clinical data, which can be used to formulate diagnostic and management plans and learn new surgical skills. Future studies with larger sample sizes and robust study designs should investigate factors that make VS effective in ophthalmic practice and education.

Predictors of Citations for Original Research in Ophthalmology.

There is a dearth of literature on factors associated with citation of publications in ophthalmology. We investigated predictors of citations for original ophthalmologic research articles based on author, study, and journal characteristics. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA), we extracted articles that studied the leading cause of vision impairment in the United States (cataract, diabetic retinopathy, age-related macular degeneration, and glaucoma) and were published in the top fifteen ophthalmology journals with the highest impact factors that accepted original research. Descriptive statistics, one-way analysis of variance (ANOVA) tests, and negative binomial regression were used to compare citation counts based on author, study, and journal characteristics. In this study, author research productivity, journal impact factor, study funding, and location in high-income countries were predictors of increased citation in ophthalmology.

Theoretical Frameworks in Medical Education: Using a Systematic Review of Ophthalmology Education Research to Create a Theory of Change Model.

Background: Theoretical frameworks provide a lens to examine questions and interpret results; however, they are underutilized in medical education. Objective: To systematically evaluate the use of theoretical frameworks in ophthalmic medical education and present a theory of change model to guide educational initiatives. Methods: Six electronic databases were searched for peer-reviewed, English-language studies published between 2016 and 2021 on ophthalmic educational initiatives employing a theoretical framework. Quality of studies was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach; risk of bias was evaluated using the Medical Education Research Study Quality Instrument (MERSQI) and the Accreditation Council for Graduate Medical Education (ACGME) guidelines for evaluation of assessment methods. Abstracted components of the included studies were used to develop a theory of change model. Results: The literature search yielded 1661 studies: 666 were duplicates, 834 studies were excluded after abstract review, and 132 after full-text review; 29 studies (19.2%) employing a theoretical framework were included. The theories used most frequently were the Dreyfus model of skill acquisition and Messick's contemporary validity framework. GRADE ratings were predominantly "low," the average MERSQI score was 10.04, and the ACGME recommendation for all assessment development studies was the lowest recommendation. The theory of change model outlined how educators can select, apply, and evaluate theory-based interventions. Conclusions: Few ophthalmic medical education studies employed a theoretical framework; their overall rigor was low as assessed by GRADE, MERSQI, and ACGME guidelines. A theory of change model can guide integration of theoretical frameworks into educational initiatives.

Glaucoma Genetic Risk Scores in the Million Veteran Program.

PURPOSE: Primary open-angle glaucoma (POAG) is a degenerative eye disease for which early treatment is critical to mitigate visual impairment and irreversible blindness. POAG-associated loci individually confer incremental risk. Genetic risk score(s) (GRS) could enable POAG risk stratification. Despite significantly higher POAG burden among individuals of African ancestry (AFR), GRS are limited in this population. A recent large-scale, multi-ancestry meta-analysis identified 127 POAG-associated loci and calculated cross-ancestry and ancestry-specific effect estimates, including in European ancestry (EUR) and AFR individuals. We assessed the utility of the 127-variant GRS for POAG risk stratification in EUR and AFR Veterans in the Million Veteran Program (MVP). We also explored the association between GRS and documented invasive glaucoma surgery (IGS). DESIGN: Cross-sectional study. PARTICIPANTS: MVP Veterans with imputed genetic data, including 5830 POAG cases (445 with IGS documented in the electronic health record) and 64 476 controls. METHODS: We tested unweighted and weighted GRS of 127 published risk variants in EUR (3382 cases and 58 811 controls) and AFR (2448 cases and 5665 controls) Veterans in the MVP. Weighted GRS were calculated using effect estimates from the most recently published report of cross-ancestry and ancestry-specific meta-analyses. We also evaluated GRS in POAG cases with documented IGS. MAIN OUTCOME MEASURES: Performance of 127-variant GRS in EUR and AFR Veterans for POAG risk stratification and association with documented IGS. RESULTS: GRS were significantly associated with POAG (P < 5 × 10-5) in both groups; a higher proportion of EUR compared with AFR were consistently categorized in the top GRS decile (21.9%-23.6% and 12.9%-14.5%, respectively). Only GRS weighted by ancestry-specific effect estimates were associated with IGS documentation in AFR cases; all GRS types were associated with IGS in EUR cases. CONCLUSIONS: Varied performance of the GRS for POAG risk stratification and documented IGS association in EUR and AFR Veterans highlights (1) the complex risk architecture of POAG, (2) the importance of diverse representation in genomics studies that inform GRS construction and evaluation, and (3) the necessity of expanding diverse POAG-related genomic data so that GRS can equitably aid in screening individuals at high risk of POAG and who may require more aggressive treatment.

Predictors of Price Transparency for Cataract Surgery and Laser Posterior Capsulotomy at Academic Hospitals in the United States.

PURPOSE: To describe the characteristics of United States (US) academic hospitals that predict transparency of cash and commercial payer-negotiated prices for cataract surgery (CS) and laser posterior capsulotomy (LPC). METHODS: A systematic review of websites for hospitals affiliated with ophthalmology residency programs was conducted to determine price transparency. Hospital characteristics were extracted from the American Hospital Association Annual Survey and Turquoise Health. Descriptive statistics, t-tests, χ2 tests, and logistic regression analyses were used to compare hospitals based on price transparency for CS and LPC. RESULTS: There were no differences in price transparency for CS and LPC based on net income, urban-rural classification, region, hospital beds, or surgical operations. Having more full-time personnel was associated with cash price transparency. No differences were identified between hospitals based on payer-negotiated price transparency. CONCLUSIONS: Academic hospitals for ophthalmology with more full-time personnel had greater cash price transparency for CS and LPC. However, price transparency did not vary for other characteristics.

Predictors of future research productivity among ophthalmology residents.

PURPOSE: To investigate the characteristics of first-year ophthalmology residents associated with high research productivity in twelve years. METHODS: All first-year ophthalmology residents in the United States (US) in 2009 listed by institutional websites were identified. Publications were obtained from Scopus and Google Scholar, h-indices were calculated, and medical school characteristics such as research productivity, region, rank, and average USMLE Steps 1 and 2 scores were obtained from National Institutes of Health, US Census Bureau, and US News. RESULTS: Data were obtained on 70% (316/453) of residents; most were male, had Doctor of Medicine (MD) degrees, and graduated from medical schools in the US or Canada. Having an additional graduate degree [OR: 3.05, 95% CI: 1.07-8.67], between 1 and 3 publications [OR: 4.16, 95% CI: 2.22-7.79], or 4 or more publications [OR: 14.27, 95% CI: 3.13-64.94] were associated with higher future research productivity. CONCLUSION: Graduate degrees and publication count were key predictors of future research productivity among ophthalmology residents in the US.

THE ASSOCIATION BETWEEN COMPLEX CATARACT SURGERY AND SOCIAL DETERMINANTS OF HEALTH IN FLORIDA.

PURPOSE: To analyze differences between rates of complex and routine cataract surgery based on demographics and social determinants of health (SDOH) at the community level. METHODS: Data from adults ages 18 to 84 relevant to cataract surgery billing codes were extracted from the 2017 Florida Ambulatory Surgery dataset from the Agency for Healthcare Research and Quality merged with SDOH measures from the American Community Survey. A multivariable logistic regression model was used to determine associations between complex cataract surgery and SDOH according to patient ZIP code. Outcomes were reported as odds ratios (OR) with 95% confidence intervals (CI). RESULTS: A total of 171,754 and 11,340 patients received routine and complex cataract surgeries, respectively; females received the majority of routine surgeries (58.87%); most common age group (79.11%) was from 65 to 84 years. Male (odds ratio [OR] 2.034; p < 0.0001) and black patients (OR 1.998; p < 0.0001) more likely received complex surgery. Compared to Medicare patients, patients insured with Medicaid (OR 2.058; p < 0.0001), private insurance (OR 1.057; p = 0.0182), or self-pay (OR 1.570; p < 0.0001) were more likely to receive a complex surgery. ZIP codes with higher adult poverty (OR 2.614; p < 0.001) were more likely complex surgery patients, whereas those with higher rates of high school attendance (OR 0.487; p = 0.0193) and home occupancy (OR 0.704; p = 0.0047) were less likely to be complex. CONCLUSIONS: Selected patient- and community-level factors including being male, Black, Asian, Hispanic, non-Medicare, or within lower education, higher poverty ZIP codes were associated with a higher likelihood of receiving complex cataract surgery.

Case Report: Ocular Manifestation of Mantle Cell Lymphoma.

SIGNIFICANCE: Mantle cell lymphoma (MCL) is a rare lymphoma that can present even more rarely in the orbit. Diagnosis, differentiation, and systemic treatment with the help of an oncologist are necessary for improved prognosis. Eye care providers must be vigilant when addressing ocular findings to determine next steps. PURPOSE: We present a case of presumed orbital fat prolapse confirmed as MCL found on routine eye examination. CASE REPORT: A 72-year-old White man presented for an annual comprehensive eye examination and was found to have conjunctival elevation in the superior and inferior fornices bilaterally. The patient had stable lymphadenopathy on positron emission tomography/computed tomography imaging 1 week before presentation. Coupled with the patient's recent diagnosis of systemic MCL, there was high suspicion that the conjunctival lesions were malignant. Biopsy of the conjunctival lesion confirmed MCL. A reevaluation of the previous imaging with a neuroradiologist confirmed the presence of orbital lesions consistent with MCL. The patient responded to treatment with low-dose focal radiation therapy. CONCLUSIONS: Primary eye care providers should be aware of limitations of orbital imaging during routine positron emission tomography and computed tomography scans in those with MCL, and consultation with neuroradiology for image review may be useful if the clinical findings are suspicious.
