Compressive optic neuropathy

Abstract

Compressive optic neuropathy occurs when an extrinsic force acts upon the optic nerve. Compression may be secondary to inflammatory, infectious, vascular, traumatic, or neoplastic lesions. Mass effect on the optic nerve compromises optic nerve axoplasmic and blood flow, leading to decreased color vision and visual acuity, visual field defects, and optic nerve edema or atrophy. A strong clinical suspicion of compression is necessary. Workup revolves around appropriate imaging of the optic nerves. Management is geared toward treating the underlying compressive etiology.
