The patient shows an extorsional downbeat nystagmus on the right eye and intorsional upbeat nystagmus on the left eye with horizontal component to the left side in the primary position. Videonystagmographic recording shows vertical eye movements. Note the patient also has a comitant hypertropia on the right eye (i.e., skew deviation) and head tilt to the left side. LV=vertical eye movement of the left eye; RV= vertical eye movement of the right eye (AVI 22405 kb)
