Fortunately, most people with optic neuritis recover much of their vision without treatment. Recovery usually begins within a few weeks, and can continue for several months. Some people, however, may not recover their normal vision, particularly if they have a pre-existing condition such as multiple sclerosis.
For some people with optic neuritis, corticosteroid medication may be used to treat their condition. This medication may speed the recovery of vision, but usually won't improve the final visual outcome.
Although some people recover normal vision without any treatment, it is very important that you consult your Eye M.D. to determine the cause of optic neuritis so that you can receive appropriate treatment and avoid permanent damage to your eyes.
