[Evaluation of the smooth pursuit test in patients with damaged cerebellar hemispheres]

The study was carried out in 52 patients in whom neurosurgical operations had been performed for tumours in the cerebellar hemispheres. The smooth following test was done by the typical pendulum test and gonioscope. It was found that disturbances of smooth following were very frequent in cases of cerebellar hemispheric damage. Abnormal records of the curves were obtained in 78% of cases in the typical pendulum test and in 96% of cases in the smooth following test in which the movements of a light spot were followed using a gonioscope.
