Amaurosis fugax, a brief loss of vision in one eye, is causedby hypoperfusion of the retinal circulation. If an attack ofamaurosis is prolonged, the patient is at risk of permanentvisual loss. Since the 1950s, amaurosis fugax has usually beenattributed to embolism from the heart or great vessels1 or tocarotid occlusive disease. Because of the difficulty in differentiatingbetween these and other causes, amaurosis fugax remains a therapeuticchallenge. Depending on the patency of the internal carotidarteries, the principal treatments are anticoagulation or antiplatelettherapy2 and carotid endarterectomy3. Vasospasm is rarely reportedas a . . .
