Transient Vertical Nystagmus: An Unusual Presentation of Thalamic Infarct

Abstract

Vertical diplopia and nystagmus typically occur in lesions of the brainstem or cerebellum. The ocular findings are exceedingly rare in thalamic infarction. The vertical gaze paresis is usually involved. Here, we describe a patient presenting with vertical diplopia and nystagmus without gaze paresis secondary to isolated medial thalamic infarct.
