Recurrent Transient Monocular Blindness with Ophthalmic Artery Stenosis

his medical record did not show any atherosclerotic vascular disease. Physical examination at admission did not reveal any bruits over either of the carotid arteries. No neurological deficits were detected. His blood pressure was 125/82 mm Hg, and his pulse rate was 72 beats/min and regular. Coagulation parameters, including antithrombin III, proDear Sir, Transient monocular blindness (TMB) or amaurosis fugax (AF) is defined as a monocular, transient visual loss lasting a few minutes, which is caused by an abrupt temporary reduction in blood flow to one eye. From increased blood viscosity to vasospasm or multiple occlusions of extracranial arteries, various mechanisms are involved in causing TMB. One of the most clearly demonstrated mechanisms is atherothrombotic embolism from the carotid artery to the ophthalmic artery. However, TMB caused by isolated ipsilateral ophthalmic artery stenosis is very rare. We experienced a patient with recurrent TMB associated with isolated proximal ophthalmic artery stenosis.
