Abstract
The aim of our work was the presence of the second phase nystagmus after rotatory, caloric and optokinetic irritation; estimation of this nystagmus magnitude and the clinical application of the second phase nystagmus. The investigation was performed in 30 healthy subjects and 65 cases of the peripheral and central vestibular pathology. Our results show that the second phase nystagmus appears more often after strong vestibular or visual irritation; the largeness of this reaction is bigger than the first reaction nystagmus. Only the asymmetry of the second phase nystagmus has the clinical apply. Labyrinthine disorders has the influence on the formation of the post-optokinetic reaction.
