Angiography of Retinal and Choroidal Vascular Disease
Amaurosis fugax, or “fleeting loss of vision”, presents as a painless, sudden monoculor loss of vision. The patient describes an acute total loss of vision, often beginning as an abrupt dimming or darkening of the visual field, proceeding to total darkness. The return of vision is characteristic. The patient likens this to a “curtain rising up again” after two to ten minutes in a sectional or piecemeal return. Generally, vision returns to absolutely normal immediately after initial episodes of amaurosis. The frequency of these episodes may vary to an isolated event to multiple “attacks” each day. Amaurosis fugax is reported to be the most common symptom of carotid artery disease(1).
