Time elapsed since ON (years)	N/A	8 ± 7		N/A
Systolic blood pressure (mmHg)	117 ± 14	123 ± 13		0.197
Diastolic blood pressure (mmHg)	72 ± 8	76 ± 8		0.128
Heart rate (bpm)	66 ± 9	69 ± 12		0.446
Mean arterial pressure (mmHg)	90 ± 12	96 ± 10		0.145
Intraocular pressure (mmHg)	13 ± 2	15 ± 3 (MS+ON)	15 ± 3 (MS-ON)	0.062
Best corrected visual acuity (Snellen decimal)	1.2 ± 0.5	1.2 ± 0.3 (MS+ON)	1.2 ± 0.2 (MS-ON)	0.937
Visual field mean deviation (dB)	−0.5 ± 1.2	−1.8 ± 3.2 (MS+ON)	−1.0 ± 2.9 (MS-ON)	0.333

Values are presented as mean ± standard deviation.

ON, optic neuritis; MS, multiple sclerosis.

p-values are calculated by one-way ANOVA.
