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 ...

Compressive Optic Neuropathy

2019
Optic nerve compression results in progressive, and often painless, vision loss. In this chapter, we begin by reviewing the clinical features of anterior and posterior compressive optic neuropathy. We next review the common causes of compressive optic neuropathy, which include orbital tumors (e.g., optic nerve sheath meningioma, optic glioma, and ...
