Title See-saw nystagmus due to unilateral mesodiencephalic lesion.

Abstract See-saw nystagmus is a unique torsional-vertical eye movement disorder with a characteristic appearance. It is a pendular nystagmus with two distinct components: a conjugate torsional component and a disjunctive vertical component. In those cases of see-saw nystagmus in which a focal lesion has been identified, the lesion is usually a bilateral, symmetric lesion located at the mesodiencephalic junction. We report an unusual case of see-saw nystagmus which was due to a strictly unilateral mesodiencephalic lesion. Furthermore, the see-saw nystagmus had, in this case, a jerk wave-form rather than the usual pendular wave-form, with the torsional component of the jerk see-saw nystagmus beating toward the side of the lesion. These observations have an impact upon the localizing and lateralizing significance of torsional nystagmus in general and of see-saw nystagmus in particular.
