The function of eye movement in 38 cases with various diseases in CNS was examined, and the following findings were obtained. The cases with supratentorial diseases did not show the value less than 50% of (FS) fixation suppression of caloric nystagmus. But many cases with infratentorial diseases, especially cerebellar diseases, had the value less than 50% of FS, and those cases showed the high incidence of disturbances of optokinetic nystgmus, eye tracking and lateral gaze. In cases with the
more » ... n cases with the value more than 70% of FS, such disturbances were hardly found. In spontaneous, positional, and positioning nystagmus tests, there was no correlation between the value of FS and the incidence of the disturbances of optokinetie nystagmus, eye tracking and lateral gage. It seems probable that the mechanism of eye fixation and eye tracking is closely related with that of FS.
