An abnormal Doll's Eyes Test finding would most likely indicate which of the following?

• A. Eyes move with the head
• B. Eyes fail to move
• C. Eyes deviate to the opposite direction
• D. Eyes blink

Answer: (B)

The key idea here is that the Doll’s eyes (oculocephalic) reflex tests brainstem integrity, especially the pathways coordinating eye movements in response to head motion. When the head is turned, a healthy brainstem drives the eyes to move in the opposite direction to keep looking at the target. If the eyes fail to move at all in response to head rotation, the reflex is absent, pointing to dysfunction of the brainstem (often midbrain/pons) and typically indicating severe brain injury or coma. That’s why “eyes fail to move” is the best choice for an abnormal finding. In contrast, eyes moving opposite to the head is the normal response, and any deviation from that normal reflex would raise concern, but the explicit absence of movement is the classic sign of brainstem impairment. Blink response isn’t part of this reflex.
