There is evidence that microemboli responsible for amaurosis fugax may be atheromatous but it can elude ophthalmoscopic confirmation, because such emboli quickly fragment and disappear from view in the retinal vessels. This report documents 2 patients in whom fluorescein angiography of the retina provided evidence of microembolization after an attack of amaurosis although the fundus appeared no...

EDITOR,-We read with interest the article by O'Sullivan et al.' The nine presented patients went through extensive investigations, including echocardiograms in all cases. Yet, no evidence of an embolic or atheromatous aetiology was found. Unfortunately, the authors failed to mention whether the echocardiography was transthoracic or transoesophageal. We had experience with a 29-year-old woman, w...

Purpose. A transient painless monocular visual loss due to a decrease in retinal circulation-also known as "amaurosis fugax"-often precedes acute territorial cerebral ischaemia. The case we present underlines the importance of a comprehensive diagnostic workup in patients with amaurosis fugax. Case Report. A 44-year-old man who had suffered from a dissection of the ascending aorta (Stanford Typ...

Nine young adults (median age 19.5 years) who suffered from amaurosis fugax (AF) are described. The attacks of AF were short in duration and preceded by premonitory symptoms in five cases and by a migrainous headache in two. In five patients the visual loss progressed in a lacunar pattern unlike the 'curtain' pattern characteristic of AF in older patients. Investigation revealed no evidence of ...

The results of carotid angiography were compared in 53 patients with amaurosis fugax and 92 with hemispheric transient ischaemic attacks (TIAs). Evidence of extracranial disease was found in 71% of those with retinal ischaemia and these patients rarely had evidence of intracranial disease (11%) or normal angiograms (15%). By contrast patients with hemispheric symptoms less frequently showed dis...

Amaurosis Fugax: Diagnostic and Therapeutic Aspects • The three to eight-year follow-up study of 34 patients with unilateral amaurosis fugax (AF) suggests the following points: (1) A significant number of frequent unilateral AF patients suffer from small ulcerative plaques or irregular stenoses without any bruit in the neck or major changes in ophthalmodynamometry (ODM). The most important diag...
