Pursuit gaze and the occipitoparietal region. A case report.
A patient lost smooth pursuit gaze to the side opposite a right occipitoparietal hemorrhage. Saccadic gaze was preserved. Pursuit gaze broken by saccades was present toward the side of the lesion. Optokinetic nystagmus (OKN) was defective when a tape was moved toward the patient from the hemianopic fields. Within two weeks, the contralateral pursuit gaze defect had cleared; however, the visual field and OKN defects and the ipsilateral pursuit gaze abnormality persisted.
