Experimental Drugs May Help the Optic Nerve Fight Glaucoma | BrightFocus Foundation

Glaucoma is a serious condition of the eyes in which the optic nerve gets damaged. This can lead to a partial or complete loss of vision.

Optic neuritis is an inflammation of the optic nerve, the bundle of nerve fibers that transmits visual information from your eye to your brain. Optic neuritis is highly associated with multiple sclerosis, a disease that causes inflammation and damage to nerves in your brain and spinal cord.
