• Ocular signs of cerebellar disease have been increasingly appreciated with the advent of means for quantitative recording of eye movements. The graphs in this article illustrate ocular flutter, dysmetria, abnormal (nonsmooth) pursuit, instability of fixation, faulty vestibular suppression, impaired optokinetic response, end-position nystagmus, and rebound nystagmus. The signs may be categorized as follows: (1) proprioceptive abnormalities manifest by flutter, dysmetria, and instability of gaze and (2) defects of vision-dependent functions manifest by abnormalities of pursuit, vestibular suppression, optokinetic response, and nystagmus.
