ID 275 – OCT and VEP in Multiple Sclerosis: Sensitivity and predictive value

Abstract

To evaluate the role of optical coherence tomography (OCT) and visual evoked potentials (VEPs) in patients with multiple sclerosis (MS). Study of 121 consecutive subjects with MS. Of 242 eyes, 166 had no previous history of optic neuritis (ON), 22 had a single recent ON episode (3 months before). All patients underwent assessment of EDSS, OCT retinal nerve fiber layer (RNFL) thickness and VEP. 77 subjects underwent to a second EDSS (EDSS2) evaluation after a mean time of 1, 94 years. In eyes with recent ON, the sensitivity of OCT was 38.9% with a higher sensitivity of VEP (77.3%; McNemar p
