  1. We created four groups within the patients: two based on the clinical history of optic neuritis (ON + and ON −), and two based on the presence of optic lesions detectable by MRI (MR + and MR −). The ‘Patients’ column containts sample sizes of pooled groups i.e. where the mean of the two optic nerves was used, whereas the ‘Eyes’ column containts sample sizes achieved by using the optic nerve diameters individually. Among both groups based on history of optic neuritis, subgroups were created according to the presence optic lesions. (e.g. 13 of the total 59 eyes without optic neuritis had asymptomatic optic nerve lesions).
