An Observation on the Eye-Speed of Nystagmus

Abstract

The results obtained are summarized as follows: (1) Eye-speed in the quick phase of nystagmus is not constant, but highly variable. (2) Eye-speeds in the slow and in the quick phase are not independent of each other, but are intimately correlative. And from their regression lines, it is suggested that the increase of eye-speed in the slow phase leads to the increase of eye-speed in the quick phase. (3) Therefore, the theory advanced by Dohlman and others that eye-speed in the quick phase is constant and the quick phase is not related to the vestibular stimuli is very doubtful.
