Optic glioma
Definition:
Gliomas are tumors that can be found in various parts of the brain. They are created by the growth of abnormal cells. Optic gliomas can affect: - One or both optic nerves -- these are the nerves that carry visual information to the brain from each eye
- The optic chiasm -- this is the region where the optic nerves cross each other in front of the hypothalamus of the brain
An optic glioma may also grow in conjunction with a hypothalamic glioma (a mass in the hypothalamus of the brain). Text Continues Below
Alternative Names:
Glioma - optic; Optic nerve glioma Causes, incidence, and risk factors:
Optic gliomas are rare and the cause is unknown. These tumors occur most often as a slow-growing, benign form in children and almost always occur before age 20. There is a strong association between optic glioma and neurofibromatosis Type 1 (NF1).
