title: Recurrent attacks of amaurosis fugax treated with calcium channel blocker.
abstract: Vasospasm may be one of the causes of amaurosis fugax. A patient is reported who daily experienced multiple brief episodes of amaurosis fugax. The absence of physical, laboratory, or radiographic evidence for thromboembolism, hemodynamic compromise, or vasculitis, suggested that the amaurosis might be caused by vasospasm. This hypothesis was supported by cessation of the attacks of amaurosis when the patient was treated with a calcium channel blocker.
