Abstract:
A 57-year-old woman presents with sudden onset of horizontal diplopia following surgical repair of a ruptured posterior fossa aneurysm. Neuro-ophthalmic examination revealed a left gaze palsy, right abducens palsy, bilateral facial nerve palsy, reverse ocular bobbing and oculopalatal myoclonus. These findings can be localized to the anterior pons caused by damage to the midline perforator vessels resulting in anterior pontine pathology. A video demonstration of the oculopalatal myoclonus and other types of vertical nystagmus is provided. The etiology and characteristics of these forms of nystagmus is discussed.
