We evaluated 23 patients with optic neuritis by magnetic resonance imaging (MRI) using STIR sequences. The series comprised 5 cases of multiple sclerosis and 18 of unknown etiology. Abnormal high-intensity area was observed in the optic nerve in at least one slice. The slices showing a high signal intensity averaged 3.4 in number. The abnormal finding was most frequent at 15mm posterior to the eyeglobe in papillitis and retrobulbar optic neuritis. The incidence of abnormal finding was more frequent in papillitis than in retrobulbar neuritis. The high-intensity signal in the optic nerve was not correlated with the latency of major positivity of pattern-reversal VEPs and was rather associated with the clinical course and outcome of optic neuritis.
