Optic neuritis facts
- Optic neuritis is an inflammation of the optic nerve.
- Optic neuritis most commonly affects young adults in one eye.
- Optic neuritis is frequently associated with 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 with recovery over weeks to a month, in most cases.
- The diagnosis is made on the basis of the patient history and an examination by an ophthalmologist. An MRI is important to look for lesions that indicate the patient may develop multiple sclerosis. Blood tests may be indicated.
- High-dose IV corticosteroids speed up recovery, but appear to have no effect on the long-term outcome.
What is optic neuritis?
Optic neuritis is an inflammation that affects the myelin lining of the optic nerve, which transmits visual stimuli to the brain. The optic nerve is actually a nerve tract of axons that originate in the ganglion cells of the retina in the back of the eye. Nerve tracts are the information pathways in the brain. The "optic nerves" are the only nerve tracts not located entirely within the brain. The optic nerves carry visual information from the retina to the area of the brain that recognizes vision (the occipital cortex).
Optic neuritis can occur in children or adults and may involve either one or both optic nerves. Optic neuritis typically affects young adults ranging from 20 to 40 years of age. There is a strong female predominance. The annual incidence is approximately 6.4/100,000.
