Optic neuritis refers to an inflammatory demyelinating attack on the optic nerves. Symptoms can include blurred or loss of vision as well as eye pain. Optic neuritis can occur in MS patients, or can occur in isolation.
Steroid treatments are often used to reduce the symptoms of optic neuritis. Other immunodulatory agents such as plasmapheresis or IVIG may be used in refractory cases.
Some cases of optic neuritis may develop MS, NMO-SD or MOG antibody associated disease recurrent disease, and may require disease modifying treatment.
