In a 20-year-old woman one of the presenting signs of multiple sclerosis was recurrent oscillopsia. Fixation of eyes while reading released during upward and downward gaze oscillopsia with variable amplitude and frequency. Electronystagmographic investigation failed to reveal signs of damage to the vestibular organ or vestibulo-oculomotor pathways. The most likely explantation of oscillopsie was, in this case, lesion of the pathway connecting the cerebellum with oculumotor nerve nuclei.
