Sudden bilateral vision loss in a COVID-19 patient: A case report

Abstract

We present a Coronavirus disease 2019 (COVID-19) patient who developed sudden bilateral vision loss after a bilateral occipital ischemic stroke and without a history of stroke risk factors. An 84-year-old man was admitted to the emergency room with bilateral sudden vision loss while receiving Favipiravir treatment for 5 days following a COVID-19 diagnosis. The patient had no history of stroke risk factors, such as hypertension, diabetes mellitus, coronary artery disease, or arrhythmia. Diffusion magnetic resonance imaging of the patient revealed acute ischemia in the bilateral posterior occipital lobe and bilateral cerebellar hemisphere. We conclude that COVID-19 may rarely cause bilateral ischemic stroke presented only in the form of vision loss.
