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

• A. Severe brain trauma
• B. No brain injury
• C. Eyes move opposite direction
• D. Eyes fail to move

Answer: (D)

The main idea is the oculocephalic reflex, often called the Doll’s eyes reflex. When the head is rotated, a normal brainstem response is for the eyes to move in the opposite direction, keeping gaze stable. This shows the brainstem circuits controlling horizontal eye movements are intact.

If the eyes fail to move in response to head rotation, the Doll’s eyes reflex is absent. That absence indicates brainstem dysfunction or severe brain injury. In such scenarios, the eyes may stay fixed in the midline or not coordinate eye movements as the head turns, pointing to significant injury rather than a preserved function.

So, an abnormal Doll’s Eyes test finding is eyes that fail to move when the head is turned, reflecting impaired brainstem function.
