Resumo
Conclusions. Dissociation of eye movements is an important sign of functional or organic lesions of the central vestibular system. Qualitative differences in the movements of each eye appear to be more serious than quantitative differences. Objective. To determine the significance of dissociated nystagmus in neurotological diagnosis. Material and methods. Eye movements were recorded separately for each eye during the neurotological examination of patients with a suspicion of central vestibular system involvement. Results. of 137 patients, 38 had quantitative dissociation of eye movements and 59 had qualitative differences. A total of 66/137 patients had abnormal MRI scans: 55 of these patients presented dissociated eye movements and only 39 had other signs of central vestibular involvement.
