[The visual fixation test in the study of visual-vestibular interactions. General aspects and results in normal subjects and patients]. / II test di fissazione visiva nello studio delle interazioni visivo-vestibolari. Generalità e risultati in soggetti normali e patologici.

ABSTRACT

Whenever we need to study visual-vestibular interactions, our method of choice among the ones based on thermal stimulation is the visual suppression test. In the vestibular laboratory of the II E.N.T. Clinic of the University of Parma the V.S.T. has been employed since 6 years systematically in all patients undergoing Electronystagmography. Our study was based on 10 normal patients and on 30 patients suffering from different pathologies. These patients were divided into groups according to the site of the lesion. The results we obtained are interesting this test gives us important clinic data that we cannot obtain using other methods and allows us to discriminate the central or the peripheral site of the vestibular system lesion.
