doll's eye sign

reflex movement of the eyes in the opposite direction to that which the head is moved, for example, the eyes being lowered as the head is raised, and the reverse (Cantelli sign); an indication of functional integrity of the brainstem tegmental pathways and cranial nerves involved in eye movement.

A clinical sign for evaluating brainstem function in a comatose patient; in a normal person, as the head is turned rapidly to one side—contraindicated if there is a possibility of brainstem injury—the eyes conjugately deviate in the direction opposite to the head’s movement; loss of this reflex implies dysfunction of brainstem or oculomotor nerves; inferolateral deviation of the eyes in combination with pupillary dilation implies dysfunction of the third cranial nerve, possibly due to tentorial herniation
