Abstract
Vertical nystagmus without a torsional component is generally considered a finding indicative of central nervous system pathology. We report two cases of purely upbeat nystagmus elicited with mastoid vibration after bilateral superior canal plugging, to highlight the vestibular pathophysiology involved in this unusual peripheral cause for upbeat nystagmus. Laryngoscope, 127:1698-1700, 2017.
