[Benign amaurosis fugax].

Abstract
In young patients episodes of amaurosis fugax usually correspond to processes not related with atherosclerosis of the extracranial vessels such as migraine, cardiac embolism, vasospasm, vasculitis, oral contraceptives or hematologic disease. In 11% of the cases, however, no cause can be found. These idiopathic cases generally have a benign course and their frequency decreases spontaneously allowing them to be described as benign amaurosis fugax. We describe four cases of amaurosis fugax in which no responsible cause was found despite extensive clinical, laboratory ultrasonographic and angiographic studies. The episodes progressively remitted. In these cases of benign amaurosis fugax the risk of a permanent deficit is exceptional and treatment is not necessary.
