Visually evoked slow eye movements, visual-vestibular interaction, and infratentorial lesions

Otolaryngol Head Neck Surg. 1983 Feb;91(1):76-80. doi: 10.1177/019459988309100114.


The maximum velocity gain of smooth pursuit and optokinetic, vestibular, and optovestibular slow phases was examined in 15 patients with pontine, 10 with medullary, 10 with cerebellar, and 5 with combined cerebello-brain stem disorders. Marked dissociations were observed between smooth pursuit and optokinetic slow phases, especially in medullary disease. A cerebellar deficit enhanced slow phase velocity gain during rotation in darkness, whereas the corresponding gain during rotation in light was normal.
