Optic Neuritis and Treatment

Optic neuritis occurs when the swelling damages the optic nerve. Pain with eye movement and temporary vision loss in one eye are the common symptoms of optic neuritis. The signs and symptoms of optic neuritis may be the first indication of multiple sclerosis (MS), or they may appear later in MS. MS is a disease that causes inflammation and damage to the nerves in the brain as well as the optic nerve. The exact cause of optic neuritis is unknown. It is thought to develop when the immune system mistakenly targets the substance covering your optic nerve, resulting in inflammation and damage to myelin.
