Comparison of Risk Factors in Patients With Transient and Prolonged Eye and Brain Ischemic Syndromes

Abstract
Background and Purpose— Patients with ischemic stroke, cerebral transient ischemic attacks (TIAs), retinal artery occlusion (RAO), and amaurosis fugax are thought to have similar risk factors and underlying vascular disease. However, if risk factors are different in patients with eye compared with brain symptoms and in those whose symptoms last 24 hours (prolonged), more focused prevention strategies are possible in the future.
