Opinion statement
In acute monosymptomatic optic neuritis, treatment with oral prednisone alone should be avoided. Therapy with intravenous methylprednisolone (1 g/day for 3 days) followed by 11 days of oral prednisone (1 mg/kg with a short taper) should be considered instead. This is particularly true if a patient considers accelerated visual recovery to be particularly urgent or if magnetic resonance imaging (MRI) demonstrates three or more signal abnormalities consistent with demyelination. In patients without a diagnosis of clinically definite multiple sclerosis (CDMS), an MRI should be considered to assess the prognosis for developing multiple sclerosis (MS) and to eliminate other causes of optic neuropathy. Foregoing an MRI or steroid treatment is an acceptable option. Chest x-ray, blood tests, and lumbar puncture are not necessary in evaluating patients with typical clinical features of optic neuritis. These tests may be appropriate, however, for patients who are about to undergo corticosteroid therapy, which could complicate or mask an unrecognized condition.

This Class I study reports the Longitudinal Optic Neuritis Study, the 5-year outcome of the ONTT patients. It documents the importance of MRI in determining the 5-year prognosis for developing MS in patients with ON. If the MRI shows three or more white matter lesions, the chance of developing MS is 51% by 5 years. If the MRI is normal, however, the chance of developing MS by 5 years is 16%.
