Abstract
The maculo-ocular reflex related to horizontal sinusoidal linear accelerations was studied in 7 patients with labyrinthine disorders, 4 with unilateral and 3 with bilateral disturbances.
1. The responses of the patients with unilateral labyrinthine disorders were the same as those of normal human subjects.
2. Reduced responses and increased phase differences were observed in the patients with bilateral labyrinthine disorders.
3. Differences in functional vulnerability between the semicircular canals and the otolith organs were demonstrated in patients with ototoxic disorders by comparing the results of the pendural rotation test with those of the sinusoidal linear acceleration test.
