Introduction

Optic neuritis is an inflammation of the optic nerve, the bundle of nerve fibers in your eye that transmits visual information to your brain. Pain and temporary vision loss are common symptoms of optic neuritis.

Optic neuritis usually develops due to an autoimmune disorder that may be triggered by a viral infection. In some people, signs and symptoms of optic neuritis may be an indication of multiple sclerosis, a condition resulting in inflammation and damage to nerves in your brain and spinal cord.

Most people who experience a single episode of optic neuritis eventually recover their vision. Treatment with steroid medications may speed up vision recovery.
