Abstract

Monocular torsional eye oscillations are a rare form of disconjugate nystagmus and the underlying pathophysiology is not well understood. Here, we present and discuss a case with disabling torsional oscillopsia in one eye only. The patient exhibited (i) spontaneous pendular torsional nystagmus of the left eye and (ii) rhythmic involuntary movements of the soft palate and uvula, consistent with the syndrome of oculopalatal tremor with monocular nystagmus. Brain MRI revealed an infarct of the left dentate nucleus in the cerebellum and, more caudally, a secondary hypertrophic degeneration of the right inferior olivary nucleus. To account for the presence of torsional nystagmus on the eye contralateral to the side of inferior olivary hypertrophy and ipsilateral to the lesioned dentate nucleus, we discuss the hypothesis of a (inferior olivary nucleus-mediated) malfunctioning adaptation of the anterior canal vestibulo-ocular reflex.
