A possible harmful late effect of methylprednisolone therapy on a time cluster of optic neuritis

Abstract
Clinical records of all patients (n= 26) suffering from optic neuritis during the last 16 years were re-evaluated in relation to treatment. The patients were treated in 3 ways: with prednisone; with “pulse” megadoses of methylprednisolone; and untreated. A possibly frightening conversion to multiple sclerosis was seen in the group of patients with methylprednisolone, compared with the other 2 groups.
