Bright-light amaurosis fugax: an unusual symptom of retinal hypoperfusion corrected by external carotid revascularization.


The eye often serves as an important monitor of carotid artery disease by manifesting visual disturbances before cerebral events. The most typical ocular symptom complex is amaurosis fugax characterized by loss of vision in one eye that occurs suddenly and clears within seconds to minutes. This symptom is a hallmark of carotid artery disease and is usually caused by an embolic event. Although monocular visual disturbance on a hemodynamic basis is a more unusual manifestation of carotid artery disease, significant stenosis in combination with a low-flow state can cause transient, unilateral telescoping of vision. This report describes another visual disturbance associated with carotid artery disease in which unilateral visual loss occurred upon exposure to bright light. We term this syndrome bright-light amaurosis fugax and document successful treatment by external carotid artery revascularization in two patients.
