Abstract
This report describes five cases of presumed progressive multiple sclerosis (MS) of late onset, four of them with predominantly or exclusively spinal manifestations, in which abnormal pattern-reversal visual evoked potentials (VEP) showed evidence of subclinical optic nerve involvement despite the absence of visual symptoms and normal neuro-opthalmological examinations. VEP measurement should be included in the evaluation of patients with myelopathy or encephalopathy of unkown etiology.
