Optic Pathway Glioma

An optic pathway glioma (also called an optic nerve glioma) is a slow-growing brain tumor that arises in or around the optic nerve, which connects the eye to the brain. As the tumor progresses, it presses on the optic nerve, causing a child's vision to worsen. Blindness can occur, but only in about 5 percent of cases. While these are serious tumors, they have a high cure rate.

Because the optic system is located near the hormone center of the brain, these tumors can affect the body's endocrine functions, such as hormone production, salt and water balance, appetite and sleep.
