title: Internuclear ophthalmoplegia associated with ipsilateral downbeat nystagmus and contralateral incyclorotatory nystagmus.
abstract: A case of left internuclear ophthalmoplegia combined with downbeat nystagmus and right incyclorotatory nystagmus on left downward gaze, left exotropia and skew deviation is presented. All signs subsided completely within about 3 months after the onset of the disease. The etiology was possibly of vascular origin. The potential site of the lesion causing these oculomotor signs is discussed.
