[The study of visual-oculomotor disturbances in otoneurological diagnosis]

The subject of work was the evaluation of diagnostic value of optokinetic nystagmus in inhibition of caloric nystagmus. Examination was performed in healthy subjects and in the peripheral and central vestibular pathology. The results of investigations show that this inhibition test is useful for differentiation peripheral and central vestibular pathology, especially supra- and subtentorial CNS lesions. Pathological result of this test in cerebellar lesions and brain-stem lesions suggest the role of these structures in the mechanism of optokinetic nystagmus.
