Optic pathway glioma - UpToDate
WebAn optic nerve glioma – also known as an optic pathway glioma (OPG) – is a slow-growing brain tumour that forms around the nerves that carry information from the eye to the brain. As the tumour grows it affects the nerves, causing problems with vision. WebOptic 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 people … WebMost investigators have divided optic pathway tu-mors into two groups: anterior optic nerve gliomas with isolated optic nerve enlargement and posterior optic nerve gliomas with optic chiasmal involve-ment. Ten to 20 year survival rates are excellent (ap-proximately 90%) for patients with optic nerve tu-mors (Weiss et al., 1987) and more ... boots lander medical practice
