Ocular Ischemic Events and Vision Loss Associated with COVID-19 Acute Hypoxic Respiratory Failure

Le résumé fourni par la source

Coronavirus disease 2019 (COVID-19) is associated with increased risk of microvascular complications; however, reports of ophthalmic manifestations associated with retinal vascular occlusion associated with COVID-19 are limited. In this report, we describe two middle-aged female patients who were admitted for acute hypoxic respiratory failure secondary to COVID-19-induced pneumonia. Following prolonged intensive care unit admission requiring mechanical ventilation and critical care interventions, both patients reported substantially reduced vision upon regaining consciousness. Dilated funduscopic exam showed multiple blot hemorrhages in all quadrants of the posterior pole, bilateral retinal hemorrhage, macular edema, and retinal vascular tortuosity. Both patients were diagnosed with retinal ischemic events owing to bilateral ophthalmic artery occlusion in the first patient, and bilateral central retinal vein occlusion (CRVO) in the second individual. While uncommon, retinal microvascular complications associated with COVID-19 leading to vision loss require prompt evaluation and referral given their potential long-term impact following acute illness.
