Oculocephalic Response
Oculocephalic Response
Oculocephalic responses are most commonly elicited in unconscious patients; the head is passively rotated in the horizontal or vertical plane (doll’s head maneuver) and the eye movements are observed. Conjugate eye movement in a direction opposite to that in which the head is turned is indicative of an intact brainstem (intact vestibulo-ocular reflexes). With pontine lesions, the oculocephalic responses may be lost, after roving eye movements but before caloric responses disappear.
