Post-caloric secondary phase nystagmus is the spontaneous direction reversal of a nystagmus peripherally induced by thermal stimuli. A 30-year-old female with cerebellar ataxia and postcaloric secondary phase nystagmus (third-phase nystagmus)is reported. CT scan showed cerebellar atrophy. Electronystagmography showed rebound nystagmus. Eye tracking test and optokinetic nystagmus suggested a cerebellar disturbance. Visual suppression was not observed.
