Add to ORKGA 25-year-old man with a history of right-sided hearing loss, headaches and imbalance was found to have a right vestibular schwannoma on MRI, and underwent a partial resection and radiotherapy. He denied symptoms of head movement dependent oscillopsia (i.e., suggestive of significant unilateral or bilateral vestibular loss), but did experience oscillopsia when looking to the right (absent head movement). With fixation, there was subtle spontaneous left-beating nystagmus (LBN) in primary position and in up and down gaze, increasing in left gaze in accordance with Alexander's law, consistent with vestibular nystagmus due to the right vestibulopathy (from the schwannoma). This vestibular nystagmus was high frequency and small amplitude. In rig...
