[Vertical vestibuloocular reflexes in unilateral labyrinthine lesions (communication I)].
Vertical vestibuloocular reflexes (VVOR) were studied in 25 patients with unilateral labyrinthine lesions and in 22 healthy subjects. The technique of VVOR is based on stimulation of the internal semicircular canals of the labyrinth by active sagittal head subduction. Dysfunction of the vertical semicircular canals manifested with: VVOR asymmetry with stronger reflexes on the side of the labyrinth affection; predominance of upward VVOR; vertical components of the horizontal vestibuloocular reflexes were not so intensive as VVOR but had the same specific features.
