Choroidal Neovascularization and Macular Hemorrhage: Real-World Experience During the New York City COVID-19 Lockdown.

Purpose: This work reviews ocular, systemic, and demographic factors contributing to presentation of choroidal neovascular membrane (CNVM)-associated macular hemorrhage after the New York City coronavirus disease 2019 (COVID-19) lockdown. Methods: A retrospective, consecutive case series was conducted of all established patients presenting with macular hemorrhage between March 22, 2020, and August 10, 2020. Results: Fourteen patients (mean age 82.2 years) were evaluated. Ten patients had active CNVMs, 1 had an inactive lesion that was last injected 2 years prior, and 3 had new conversions from nonexudative age-related macular degeneration. In the actively treated CNVM group there was a delay in expected follow-up from 50.4 days to 125 days. Eight patients with previously active CNVM (73%) had a history of prior macular hemorrhage. Eight patients (57%) were on some form of antiplatelet or anticoagulation therapy. Twelve patients (86%) had COVID-19-specific risk factors besides age, and all but 1 patient (93%) delayed care without discussion with a physician. Ten patients (71%) had more than 1 week of symptoms prior to presentation. Twelve patients (86%) had signs of CNVM on prior optical coherence tomography. Conclusions: Adequate documentation of potential risks for hemorrhage (particularly prior hemorrhage or presence of subclinical type 1 CNVM), as well as COVID-19-specific risk factors, would aid triage of clinic appointments in future lockdowns. High-risk patients would likely benefit from direct physician communication discussing their individual risk profiles to alleviate anxiety over clinic visits and communicate their risk of severe vision loss.

Bilateral macular hemorrhage in a patient with COVID-19.

PURPOSE: We report a case of a patient with a known hereditary spherocytosis who developed a bilateral macular hemorrhage in concurrence with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related respiratory syndrome. OBSERVATIONS: Blood tests showed severe hemolytic anemia. Interestingly, the peripheral blood smear demonstrated a mixed pathogenesis of the hemolytic process (cold-agglutinin-mediated and non-immune-mediated due to spherocytosis). CONCLUSIONS AND IMPORTANCE: We argue that SARS-CoV-2 could have triggered the hemolytic process, which led to retinal hemorrhages due to endothelial anoxia from the low oxygen carrying capacity.
