Optic neuritis is an inflammation of the optic nerve. It is usually experienced as acute, painful blurring or loss of vision in one eye. Vision generally worsens over the course of a few days and improves during the next one to three months. It is possible to have optic neuritis without loss of vision so that a person is not aware of symptoms. In such cases, diagnostic tests are useful in detecting the condition. Optic neuritis has been linked to multiple sclerosis and may be its first symptom. However, not everyone who has optic neuritis develops multiple sclerosis.
