Vertical vestibuloocular reflex (VVOR) suppression was studied in 25 patients with unilateral labyrinthine disorders and 22 healthy individuals. The method of the suppression investigation was based on stimulation of the internal semicircular channels of the labyrinth by active sagittal nodding with glance fixation of the object moving with the head. VVOR suppression by glance reflex in patients with unilateral labyrinthine lesion is characterized by reduced reflex suppression effectiveness, especially on the side of the affected labyrinth, via a significant VVOR phase shift down.
