	FA^b,^c	ADC (×10⁻⁶ mm²s⁻¹)^b,^c	λ_‖(×10⁻⁶ mm²s⁻¹)	λ_⊥(×10⁻⁶ mm²s⁻¹)^b,^c	Whole-Field VEP Amplitude (μV)^b,^c	Whole-Field VEP Latency (ms)^b,^c
Patients' affected nerves (n = 26)	0.283 ± 0.073	1429 ± 198	1786 ± 159	1245 ± 172	4.53 ± 1.17	132.7 ± 17.48
Patients' unaffected nerves (n = 26)	0.569 ± 0.046	1028 ± 146	1720 ± 199	746 ± 78	9.67 ± 2.52	94.86 ± 9.07
Control nerves (n = 15)	0.587 ± 0.023	1008 ± 111	1702 ± 199	729 ± 130	9.40 ± 3.03	97.77 ± 4.62

a The values are mean ± SD.
b Significant difference between nerves of controls and affected nerves of patients.
c Significant difference between unaffected contralateral nerves and affected nerves in patients. There is no significant difference between unaffected ONs of patients and ONs of controls in all DTI measures.
