title: The contribution of saccadic eye movements analysis, visual and auditory evoked responses to the diagnosis of multiple sclerosis.
abstract: A number of tests have been used to identify paraclinical evidences of central nervous system (CNS) lesions in multiple sclerosis (MS). The present study was aimed to test and compare the diagnostic value of saccadic eye movements (SEM) analysis, and visual and auditory brain stem evoked responses (VER, ABER) in MS, and to study the correlation between electrophysiologic findings and clinical data. The reference group for epidemiological and statistical analysis was selected from the group of 109 suspected MS patients included in the study. SEM analysis resulted at least as sensitive as VER and ABER. SEM analysis showed good sensitivity and positive predictive value. Saccade latency resulted the most sensitive SEM parameter. Subclinical internuclear ophthalmoparesis resulted highly specific. We suggest that SEM analysis could be included into the electrophysiologic tests for identifying paraclinical evidences of CNS lesions in MS. Correlations between electrophysiologic findings and clinical data are discussed.
