Abstract
A group of 17 patients having had at least one attack of amaurosis fugax was studied. All had had an angiographic exploration and an electrocardiogram. Seven out of the 17 were subjected to more extensive cardiac investigations (echocardiography = five cases; phonocardiogram = two cases). Various risk factors were searched for.In 11 out of the 17 patients, a certain origin of the transient monocular blindness could be confirmed (internal carotid artery: ten cases; heart: one case); in three cases the origin was doubtful (I.C.A.: one case; heart: two cases); in three other cases, no origin could be confirmed.The results of this study point to the relatively high frequency of cardiac disease in amaurosis fugax. When the carotid angiogram is normal, a cardiologic exploration is absolutely necessary.
