Clinical, Doppler and angiographic findings are described in 53 consecutive patients who presented with amaurosis fugax (AF) in a total of 57 eyes; 4 had non-simultaneous attacks in both eyes. Atherosclerotic lesions were detected on Doppler or angiographic (conventional arteriography and/or intravenous digital subtraction angiography) examination in 36 (63%) of the relevant precerebral internal carotid arteries (ICA) in 34 patients. Nineteen (53%) of these lesions caused a diameter reduction of more than 75%. Patient age was the most important factor in predicting the presence of relevant carotid occlusive disease, all 36 lesions being found in patients over 50 years of age. Two unusual cases of AF are described; in one AF was caused by stenosis of the ipsilateral ophthalmic artery, and in another by occlusion of the brachiocephalic artery with a steal syndrome from the right common carotid artery (CCA) to the right subclavian artery.
对连续53例出现一过性黑矇（AF）的患者（共57只眼）的临床、多普勒及血管造影检查结果进行了描述；4例双眼发作不同步。在34例患者的36条（63%）相关大脑前颈内动脉（ICA）中，通过多普勒或血管造影检查（传统动脉造影和/或静脉数字减影血管造影）发现了动脉粥样硬化病变。其中19处（53%）病变导致管径缩小超过75%。患者年龄是预测相关颈动脉闭塞性疾病存在的最重要因素，所有36处病变均见于50岁以上患者。描述了2例不寻常的AF病例；1例AF由同侧眼动脉狭窄引起，另1例由头臂动脉闭塞并伴有从右颈总动脉（CCA）至右锁骨下动脉的盗血综合征引起。
