Abstract
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.Keywords
