Article Abstract
We describe 17 patients with acquired convergence-evoked nystagmus(CEN). Vertical CEN was most common(82%),with upbeat much more frequent than downbeat.The most common diagnoses were multiple sclerosis(41%)and brainstem infarction(29%).CEN is an easily elicited bedside sign of posterior fossa dysfunction and can be a clinically useful manifestation. In cases of isolated optic neuritis,the presence of CEN may indicate dissemination of neurologic disease.
