Non-arteritic Anterior Ischemic Optic Neuropathy Sequela From Potential COVID-19-Associated Coagulopathy

Abstract

We report a case involving a post-menopausal female who experienced a sudden loss of peripheral vision in her right eye seven months after a confirmed COVID-19 infection. MRI scans of the brain and orbit excluded neuritis and multiple sclerosis, leading to the diagnosis of non-arteritic anterior ischemic optic neuropathy (NAION). It is known that the intense inflammatory condition resulting from acute respiratory distress syndrome triggered by SARS-CoV-2 infections can result in a heightened tendency for blood clot formation. Emerging research underscores the potential link between the likelihood of a thrombotic event in the eye as a consequence of COVID-19 infection and the development of NAION. The connection between NAION and COVID-19, whether it is correlative or coincidental, remains uncertain. However, this case report aims to present evidence for the plausibility of this link and offer insights into potential ophthalmologic complications caused by COVID-19.
