Abstract
Patients (59) had arteriography because of episodes of amaurosis fugax. Only 1/3 of them had atherosclerotic lesions potentially treatable by carotid endarterectomy. Another 3rd had normal arteriograms, some of these had migraine, heart disease or platelet disorders presumed to be the cause of their symptoms. Patients with amaurosis fugax are a heterogenous group, and their visual symptoms should not be considered a specific indicator of stenosis of the internal carotid artery.
