Ophthalmologic nvolvement in SARS-CoV-infected patients is variegated. One of the ophthalmologic pathologies is optic neuritis. Optic neuritis in SARS-CoV-infected patients may precede the classical pulmonary manifestations of COVID-19 and can be unilateral or bilateral. Optic neuritis has been repeatedly reported in COVID-19 patients and may occur with or without affection of other cranial nerves. Since cerebro-spinal fluid parameters can be abnormal in COVID-19 associated optic neuritis, these patients require a spinal tap. Before diagnosing SARS-CoV-2 associated optic neuritis various differentials need to be excluded. Since SARS-CoV-2 causes endothelial damage complicated by thrombus formation and thromboembolism, ophthalmologic vascular complication due to an infection with SARS-CoV-2 such as anterior ischemic optic neuropathy (AION), central retinal artery occlusion (CRAO), and retinal vein occlusion need to be excluded. CRAO may result from arterial hypertension, myocarditis, heart failure, Takotsubo syndrome, atrial fibrillation, or atrial flutter, frequent cardiac complications of COVID-19. Since CRAO can be accompanied by ischemic stroke, patients with SARS-CoV-2 associated optic neuritis need to undergo a cerebral MRI.
