Purpose of Review: This review focuses on aspects of retinal and optic nerve ischemia that may be encountered by neurologists. Recent Findings: Recent guidelines have emphasized the similarities between cerebral and retinal ischemia in terms of etiologic workup, acute management, and subsequent stroke risk. However, although ischemic optic neuropathies reflect optic nerve ischemia, they result from local small vessel disease and are not associated with a higher risk of cerebral infarction. Their management is therefore very different from acute cerebral ischemia. It is essential to rule out giant cell arteritis in all patients with acute retinal or optic nerve ischemia. Summary: Because the eye is vascularized by branches of the internal carotid artery, retinal ischemic symptoms are common in patients with anterior circulation ischemic strokes. Patients with central retinal artery occlusion, whether permanent or transient (responsible for transient visual loss), need to be evaluated and managed emergently similar to patients with cerebral ischemia, while anterior and posterior ischemic optic neuropathy are more concerning for giant cell arteritis. © 2014, American Academy of Neurology.
