Abstract

Phosphenes, flashes of light, are a visual phenomenon experienced by patients with ophthalmological disease and normal individuals. We report here a 68-year-old woman in whom phosphenes appeared in the left visual field due to compression of the right optic nerve by an aneurysm of the anterior communicating artery. The symptom decreased dramatically after clipping of the aneurysm. Phosphenes may be an important early sign of vascular compression neuropathy of the optic nerve.
