Compressive Optic Neuropathy
Introduction
Compressive optic neuropathy is damage that occurs when something (usually a tumor) presses on the optic nerve. Compression of the optic nerve causes slow, painless, progressive loss of vision. Imaging of the optic nerve (usually by magnetic resonance imaging [MRI]) should be done to evaluate for a mass or tumor. Treatment depends on the cause but often involves surgery.
