Hemi- and Central Retinal Vein Occlusion Associated with COVID-19 Infection in Young Patients without Known Risk Factors.

PURPOSE: Venous thromboembolic complications have been reported in association with coronavirus disease 2019 (COVID-19) infection. We raised awareness regarding a potential temporal association between COVID-19 infection and retinal vein occlusion (RVO). DESIGN: Multicenter, retrospective, nonconsecutive case series. SUBJECTS: Patients presenting with hemi-RVO (HRVO) or central RVO (CRVO) between March 2020 and March 2021, with confirmed COVID-19 infection, were included. The exclusion criteria were as follows: age >50 years, hypertension, diabetes, glaucoma, obesity, underlying hypercoagulable states, and those requiring intubation during hospitalization. METHODS: This was a multicenter, retrospective, nonconsecutive case series including patients presenting with hemi-RVO (HRVO) or central RVO (CRVO) between March 2020 and March 2021, with confirmed COVID-19 infection. The exclusion criteria were as follows: age >50 years, hypertension, diabetes, glaucoma, obesity, underlying hypercoagulable states, and those requiring intubation during hospitalization. MAIN OUTCOME MEASURES: Ophthalmic findings, including presenting and final visual acuity (VA), imaging findings, and clinical course. RESULTS: Twelve eyes of 12 patients with CRVO (9 of 12) or HRVO (3 of 12) after COVID-19 infection were included. The median age was 32 years (range, 18-50 years). Three patients were hospitalized, but none were intubated. The median time from COVID-19 diagnosis to ophthalmic symptoms was 6.9 weeks. The presenting VA ranged from 20/20 to counting fingers, with over half (7 of 12) having a VA of ≥20/40. OCT revealed macular edema in 42% of the eyes; of these, 80% (4 of 5) were treated with anti-VEGF injections. Ninety-two percent (11 of 12) had partial or complete resolution of ocular findings at final follow-up. Four eyes (33%) had retinal thinning, as determined using OCT, by the end of the study interval. The final VA ranged from 20/20 to 20/60, with 11 of the 12 (92%) eyes achieving a VA of ≥20/40 at a median final follow-up period of 13 weeks (range, 4-52 weeks). CONCLUSIONS: Although we acknowledge the high seroprevalence of COVID-19 and that a causal relationship cannot be established, we reported this series to raise awareness regarding the potential risk of retinal vascular events due to a heightened thromboinflammatory state associated with COVID-19 infection.

Ocular trauma secondary to exercise resistance bands during the COVID-19 pandemic.

OBJECTIVE: To characterize injuries caused by exercise resistance bands. METHOD: Single-site retrospective case series of patients presenting to the Bascom Palmer Eye Institute emergency room with ocular injuries secondary to exercise resistance bands from March through September 2020. RESULTS: Eleven patients (9 males, 2 females, 14 eyes) were reviewed. Eight patients had a unilateral injury (3 right eyes, 5 left eyes) while 3 had bilateral injuries. Iritis was the most common presentation, seen in all 11 patients, followed by hyphema (9 patients, 82%), and vitreous hemorrhage (4 patients, 36%). Among affected eyes, the mean presenting visual acuity was approximately 20/100, improving to 20/40 on the last follow up (p = 0.06). However, 4 eyes (33%) had vision ≤20/60 at last follow up. CONCLUSIONS: Exercise resistance bands can cause a wide spectrum of ocular injuries, some leading to long-term vision loss. As such, we recommend that patients strongly consider using eye protection goggles or glasses while using resistance bands for exercise.

Emergent Ophthalmic Surgical Care at a Tertiary Referral Center During the COVID-19 Pandemic.

PURPOSE: This study characterized the delivery of emergent ophthalmic surgical care during April 2020 of the coronarvirus disease-19 (COVID-19) pandemic compared with the same interval the previous year. DESIGN: Retrospective observational before-and-after study. METHODS: This study reviewed and characterized each emergent and/or urgent procedure performed during April 2020 and April 2019 at a single tertiary ophthalmology referral center. Information collected included the details of patient presentation, diagnosis, surgical procedure, and preoperative COVID-19 testing. RESULTS: In total, 117 surgical procedures were performed on 114 patients during the month of April 2020 compared with 1,107 performed in April 2019 (P < .0001). Retinal detachment repair was the most common procedure (n = 37; 31.6%) in April 2020, whereas elective cataract surgery (n = 481; 47.3%) was the most common procedure in April 2019. The mean age of patients was 50.0 years in April 2020 compared with 59.0 years (P < .0001) the previous year. During April 2020, the mean age of surgeons performing procedures was 42.3 years compared with 48.4 years (P < .0001) during April 2019. In April 2020, all but 5 patients (96%) had reverse transcriptase polymerase chain reaction based COVID-19 testing before their procedure. One patient (0.88%) had a positive COVID-19 test. CONCLUSIONS: The COVID-19 pandemic decreased our institution's surgical volume in April 2020 to approximately 10% of the usual volume. The pandemic changed the type of cases performed and led to a statistically significant decrease in both the age of our surgeons and patients relative to the same interval in the previous year. Broad preoperative screening led to 1 positive COVID-19 test in an asymptomatic patient.
