Reading-evoked visual dimming.
Abstract
PURPOSE: To carry out a neuroradiologic investigation in a monocular 49-year-old patient who during the past five years described symptoms of dimming of central vision in his left eye, which was provoked only by reading. METHODS: Computed tomography and magnetic resonance imaging were performed. RESULTS: An orbital apex intraconal tumor situated laterally to and above the optic nerve was found. CONCLUSIONS: Reading-evoked visual dimming can be a variant of gaze-evoked amaurosis. The optic nerve displaced laterally and superiorly, and stretched by the act of reading, may be compressed between the tumor above and the contracted inferior rectus muscle inferiorly.
