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.  
Optic gliomas are usually pilocytic tumors, and can involve the
optic nerve or optic chiasm. Optic gliomas are usually associated with  neurofibromatosis type 1 in 30% of patients. 
Treatment [ edit ]
radiation or chemotherapy may be helpful, treatment is often not necessary. 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.  
Prognosis [ edit ]
Optic gliomas often have a shifting clinical course, with sporadic periods of vision loss separated by long periods of visual stability.
Optic gliomas rarely spontaneously regress.
