Acute Vision Loss
Key Points
Diagnosis and treatment should occur as rapidly as possible. Immediate referral to a stroke center if an acute embolic event is suspected (eg, amaurosis fugax, retinal artery occlusion, ischemic stroke). Acute monocular loss of vision with an afferent pupillary defect indicates a lesion of the eye or of the optic nerve anterior to the optic chiasm. Optic nerve lesion, particularly ischemia, is considered in patients with acute monocular loss of vision or afferent pupillary defect without eye pain and in those with or without optic nerve abnormalities on ophthalmoscopy but no other abnormalities on eye examination.
