[The characteristics of vestibular-visual interaction in patients with cochleovestibular disorders under galvanic stimulation].

The paper deals with the problem of vestibular-visual interactions in pathogenesis of cochleovestibular diseases. The investigations were made on the original unit for registration of visual illusions in response to galvanic stimulation of vestibular structures. The examination covered patients with Meniere's disease, peripheral and central cochleovestibular syndrome, otogenic arachnoiditis. Emergence of visual illusions was related to the degree of vestibular abnormality and threshold stimulation. The greatest compensation of the equilibrium function at the expense of vision was reported in patients with central vestibular disorders. Further studies into the vestibular reactions seem important for elucidation of cochleovestibulopathy pathogenesis.
