A 77-year-old man with autopsy-proven bilateral cerebral infarction had a periodic alternating conjugate horizontal ocular deviation for 2 days, which ceased shortly before death. There have been four previously reported patients with this disorder. The phenomenon suggests acute bilateral cerebral disease with a relatively intact brainstem.
