Anatomical correlates of ocular motor deficits in cerebellar lesions.

Baier B1, Stoeter P, Dieterich M.Author information 1Department of Neurology, Johannes Gutenberg-University, Mainz, Germany. baierb@uni-mainz.deAbstractHumans are able to stabilize the images of moving targets on the retina by means of smooth pursuit eye movements. After the pontine level, all smooth pursuit pathways pass through the cerebellum. Previous animal studies gave evidence that two specific lesion sites within the cerebellum cause smooth pursuit disorders: those of the flocculus/paraflocculus and the vermis including lobule VI, VII, the uvula and the deep cerebellar nuclei. To date, there have been only a few lesion studies in patients with smooth pursuit disorders that do not allow direct comparison with a control group. In the present study, new lesion mapping techniques determined which cerebellar structures were involved in patients with deficits of smooth pursuit eye movements, slow phase of optokinetic nystagmus (OKN) and fixation suppression of vestibulo-ocular reflex, i.e. in eye movements that are considered to belong to the smooth pursuit system. The aim was to elucidate whether there is an anatomical and clinical link between these different eye movement disorders. Seventeen patients with acute, mainly unilateral cerebellar infarctions and an intact gain of the smooth pursuit system were compared with 11 patients with cerebellar lesions and deficient gain of sinusoidal smooth pursuit eye movements by means of lesion-mapping imaging. In addition, lesion analyses were conducted in subgroups with impaired fixation suppression of vestibulo-ocular reflex and deficient gain of the slow phase of the OKN. The uvula and partly the vermal pyramid were found to be the structures commonly damaged in patients with deficient gain of the horizontal sinusoidal smooth pursuit eye movement, of the slow phase of the OKN and impaired fixation suppression of vestibulo-ocular reflex; and were less involved in patients with intact smooth pursuit system. The present data give evidence for an anatomical link between sinusoidal smooth pursuit eye movements, fixation suppression of vestibulo-ocular reflex and the slow phases of OKN implying that the uvula and the vermal pyramid are important structures for generating slow phases within the smooth pursuit network in humans.
