Dissociated Vertical Nystagmus and Internuclear Ophthalmoplegia from a Midbrain Infarction Arch Neurol 48:1304-1305, Marshall,R.S.,et al, 1991 See this aricle in Pubmed Article Abstract We describe a patient with a dissociated vertical nystagmus and an internuclear ophthalmoplegia.The vertical nystagmus consisted of a left downward nystagmus with a synchronous right intorting nystagmus when the patient looked down and to the left.This rare type of nystagmus has been described both in isolation and in association with an internuclear ophthalmoplegia.Previous authors postulated a lesion in the mid-brain in the region of the medial longitudinal fasciculus.In our patient,a discrete midbrain infarction was demonstrated on magnetic resonance imaging in the hypothesized location,thus providing supportive anatomical evidence for a vertical gaze coordination pathway in the region of the medial longitudinal fasciculus.
