Overview
Optic nerve glioma (or optic glioma), a form of glioma which affects the optic nerve, is often one of the central nervous system manifestations of Neurofibromatosis 1.

Gliomas are tumors that grow in various parts of the brain. Optic gliomas can affect:


 * One or both of the optic nerves, which carry visual information to the brain from each eye


 * The optic chiasm, the area where the optic nerves cross each other in front of the hypothalamus of the brain

An optic glioma may also grow along with a hypothalamic glioma.
