Overview, Causes, & Risk Factors

The cause of optic neuritis is unknown. Sudden inflammation of the optic nerve (the nerve connecting the eye and the brain) leads to swelling and destruction of its outer shell, called the myelin sheath. The inflammation may occasionally be the result of a viral infection or it may be caused by autoimmune diseases such as multiple sclerosis. Risk factors are related to the possible causes.
