Bilateral ocular motor signs after tentorial herniation in 25 patients

Twenty-five patients with upper brain-stem damage after severe transtentorial herniation showed a variety of residual oculomotor signs. Pupillary abnormalities (19 patients), ptosis (15 patients), internuclear ophthalmoparesis (13 patients), vertical gaze paresis (14 patients), and third-nerve dysfunction (11 patients) were the principal findings.
