Abstract:
The interference of optokinetic nystagmus from vestibular nystagmus was evaluated in 10 patients with a pre-existing spontaneous peripheral vestibular nystagmus, and in 9 normal subjects, in whom vestibular nystagmus was induced with 10 times of 60?sec constant speed count-clockwise rotation. The examinees of both groups were all subjected to horizontal clockwise and counter-clockwise optokinetic stimulation(target speed 60?/sec, frequency 2 Hz).It was found that vestibular nystagmus exerted no significant modifying effect on the eye velocity of the slow phas? of optokinptic nystagmus and that no favourablp evid?cs was demonstrated to support the algebraic summation hypothesis.
