Optic Nerve Glioma: Understanding a Rare Brain Tumor

Optic nerve glioma is a rare type of brain tumor that develops in or around the optic nerve, the structure responsible for transmitting visual signals from the eye to the brain. Although it can occur at any age, optic nerve gliomas are most commonly diagnosed in children, especially those under the age of ten. They are usually low-grade, slow-growing tumors, but their location makes them significant due to their impact on vision and overall neurological health.

These tumors belong to the category of gliomas, which arise from glial cells—the supportive cells of the nervous system. In optic nerve glioma, the tumor typically involves the optic pathway, including the optic nerves, optic chiasm, and sometimes the hypothalamus. Because of this involvement, patients often experience progressive vision problems, ranging from blurred vision and reduced visual acuity to complete vision loss in severe cases.
