Optic neuritis is an inflammation of the optic nerve of either or both eyes,
typically affecting young adults.
It may be triggered by a viral infection, but it is also sometimes an indication
of multiple sclerosis. Other causes include infections, autoimmune disease, and
injury to the optic nerve.
The symptoms of optic neuritis include vision loss, reduced color vision, and
pain on movement of the eye.
The diagnosis is made on the basis of the patient history and an examination
by an ophthalmologist. Blood tests and MRI scan of the brain may be indicated.
Most cases of optic neuritis improve over a period of weeks. Treatment with
corticosteroids may hasten recovery.
