The study concluded that patients with acute optic neuritis could be given the options of no treatment or IV methylprednisolone followed by oral prednisone. An important and unexpected finding of the study was that the IV methylprednisolone group had a reduced risk of a secondary demyelinating event of any kind for the first 2 years after treatment compared to the other two treatment groups; however, this protective effect was lost by year 3 and at all subsequent time points.
