Optic neuritis

Overview

Type of disease: Rare conditions

Optic neuritis is inflammation of the optic nerve, the nerve that carries the visual signal from the eye to the brain.  The condition may cause sudden, reduced vision in the affected eye(s). While the cause of optic neuritis is unknown, it has been associated with autoimmune diseases, infections, multiple sclerosis, drug toxicity and deficiency of vitamin B-12. Vision often returns to normal within 2-3 weeks without treatment. In some cases, corticosteroids are given to speed recovery. If known, the underlying cause should be treated.
