Abstract
Anterior ischemic optic neuropathy (AION) is the most frequent cause of acute optic nerve damage in the elderly, usually causing acute, unilateral, and painless permanent visual loss. Arteritic anterior ischemic optic neuropathy (AAION) is a result of endothelial cell inflammation and the subsequent thrombosis and occlusion in the blood-supplying arteries of the optic nerve head. AAION accounts only for 5-10% of all AION cases that are associated with vasculitis which usually takes place in the course of a giant cell arteritis (GCA). In this paper, we report a case of AAION following a COVID-19 respiratory infection. Although it is uncertain whether SARS-CoV-2 infection triggered the AAION or was coincidental, the possible association of the events is concerning.
