title: Facially distributed pattern-evoked potentials in multiple sclerosis.
abstract: Among 56 established cases of multiple sclerosis in our clinic from April 1978 to March 1985, optic neuritis was found in 38; 21 cases were bilateral. We studied pattern-evoked potentials detected with 16 electrodes placed on both the scalp and the facial area. Pattern-evoked potentials (PERGs) were obtainable at the facial area in multiple sclerosis patients with optic neuritis, except in long-standing cases. However, a significant reduction of amplitude was found even in cases without optic neuritis. No correlation was found between visual acuity and amplitude or peak latency of PERGs in MS patients.
