Ocular signs of cerebellar disease
D. G. Cogan, F. C. Chu and D. B. Reingold
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.
