Optic neuritis is an inflammation of the optic nerve, which includes the bundle of nerve fibers which transmits visual information from your eye to your brain. Temporary vision and pain are most common symptoms of optic neuritis. The prevalence rate of ON in Spain as on 31 December 2012 was 2.75 cases per 100,000 people. The mean annual prevalence of ON during the 2008-2012 period was found to be 7.87 cases per 100,000 person-year and the annual incidence rate was 5.36 cases per 100,000 person-years.
Treatment usually includes steroid medications such as Orason, Deltason, Prednison, Methylprednisolone or others which can speed up the persons vision recovery time. While treatment with steroids may have little effect on the end visual outcome of people with optic neuritis, people who are under medication with intravenous steroids have the risk of developing multiple sclerosis in two years when compared to people who do not receive such treatment.
The primary aim is to develop a framework for evaluating interventions in ON and in order to assess their ability to restore normal tissue, restore optimal neurological function, re-establish normal physiology. People with optic neuritis have a good recovery of their vision and may not have any long term problems with their sight.
