Some patients with CRAO reveal a history of amaurosis fugax (transient vision loss lasting seconds to minutes but that may last up to 2 hours), which may result from transient CRAO. The vision usually returns to baseline after an episode of amaurosis fugax.

The clinician should inquire about the symptoms of temporal arteritis in older patients (eg, headache, jaw claudication, scalp tenderness, proximal muscle and joint aches, anorexia, weight loss, fever).

The past medical history should include any medical problems that could predispose to embolus formation (eg, atrial fibrillation, endocarditis, atherosclerotic disease, hypercoagulable state). Other predisposing factors include prolonged direct pressure to the globe during drug-induced stupor or improper positioning during face-down surgical procedures. The physician should also inquire about any illicit drug history.
