 PDF
- Ocular contrapulsion refers to a syndrome of static ocular deviation and saccadic hypermetria toward the intact side, and saccadic hypometria and impaired smooth pursuit toward the lesion side. It has been reported in patients with lesions in the rostral cerebellum and caudal medullary hemorrhge. We report a 60-year-old man who showed ocular contrapulsion with unilateral upper medial medullary infarction. Ocular contrapulsion may be a sign of medial medullary infarction. In our patient, the climbing fibers may be damaged before crossing the midline in the upper medulla.
