In our study, for the patients with idiopathic (monosymptomatic) optic neuritis, 50% (5/10) had normal brain MRI fi ndings, 20% (2/10) were classifi ed as grade I and 10% (1/10) grade II, III and IV, respectively. In comparison, the ONTT fi gures were 40.9% normal, 10.8% grade I, 9.1% grade II, 6.7% grade III and 32.5% grade IV.
