Description This is a 45-yo-man who was recently diagnosed with SCA 6. There was no clear spontaneous downbeat nystagmus (DBN) in primary gaze, although DBN could clearly be provoked by convergence. Other ocular motor features included choppy pursuit and VOR suppression horizontally and vertically, in addition to an alternating hypertropia (skew deviation), gaze-evoked and rebound nystagmus. Saccades were normal. His VOR was completely normal. These are all typical ocular motor features of a flocculus/paraflocculus syndrome.
