Branch Retinal Artery Occlusion in Patient with COVID-19: Case Report
Abstract
Dear Editor, There are many reports of coronavirus disease 2019 (COVID-19) patients presenting with arterial (stroke, myocardial infarction) and venous thrombosis (deep vein thrombosis, pulmonary thromboembolism, venous sinus thrombosis) [1]. However, few of the studies documenting thromboembolic complications in COVID-19 patients have presented data on ocular circulation. Many mechanisms can cause retinal artery occlusion, including exogenous or endogenous embolization, thrombosis, vasculitis, and vasospasm, all of which can occur alone or in combination. Retinal artery occlusions in young adults occur secondary to various pathological conditions. In retinal artery occlusion in young patients, unlike the elderly, the most common occlusion mechanism is embolism from the carotid artery, cardiac embolisms, and various hypercoagulable states that lead to thrombosis and are more common in younger patients. COVID-19 infection can lead to severe complications such as arterial and venous obstruction, microinfarctions, and multi-organ failure [2]. We report a young patient with COVID-19 pneumonia who developed branch retinal artery occlusion (BRAO). A 34-year-old female patient with bilateral diffuse thickening of the interstitial structures and multiple groundglass opacities on chest X-ray was diagnosed with mild COVID-19-related pneumonia. She had a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction test on July 31, 2020. She was…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 19 participants or records.
