Gaze-induced amaurosis from central retinal artery compression.

Abstract
Color Doppler imaging was used to evaluate a patient with gaze-induced amaurosis caused by an intraconal orbital mass. The time-velocity waveform demonstrated abnormally high vascular resistance in the central retinal artery of the affected eye in the primary position. Abduction of the affected eye resulted in transient visual loss with an unreactive pupil. This same maneuver during color Doppler imaging resulted in a dramatic reduction of blood flow in the central retinal artery. Two months after surgical excision of the mass, the gaze-evoked amaurosis was no longer present, and color Doppler imaging demonstrated normal blood flow in the central retinal artery. This suggests that impaired retinal and optic nerve blood flow are responsible for gaze-induced amaurosis from compressive orbital lesions.
