  • Title: Asymmetrical ocular pursuit with posterior fossa tumors.
    Author: Furman JM, Hurtt MR, Hirsch WL.
    Journal: Ann Neurol; 1991 Aug; 30(2):208-11. PubMed ID: 1897912.
    Abstract:
    We report two patients with posterior fossa neoplasms who demonstrated asymmetrically impaired horizontal ocular pursuit documented with electrooculography. One patient had impaired pursuit contralateral to a pontomedullary lesion, whereas the second patient had impaired pursuit ipsilateral to a pontocerebellar lesion. These patients demonstrate that posterior fossa lesions may impair ocular pursuit either contralaterally or ipsilaterally unlike cerebral hemispheric lesions, which impair ocular pursuit ipsilaterally or bilaterally.
