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.[1][2]
Optic gliomas are usually pilocytic tumors, and can involve the optic nerve or optic chiasm.[3] Optic gliomas are usually associated with neurofibromatosis type 1 in 30% of patients.[3]
Treatment
While radiation or chemotherapy may be helpful, treatment is often not necessary.[3] Optical gliomas often cannot be surgically resected. If no visual symptoms wait 6 months and then in 6 months only treat if there are symptoms (visual loss, eye pain), otherwise do not treat.[3]
Prognosis
Optic gliomas often have a shifting clinical course, with sporadic periods of vision loss separated by long periods of visual stability.[3] Optic gliomas rarely spontaneously regress.[3]
