What does the presence of the oculocephalic reflex in an unconscious child indicate?

The presence of the oculocephalic reflex, often referred to as the "doll's eyes" reflex, in an unconscious child is considered expected because it indicates the integrity of the brainstem function. This reflex occurs when the head is turned to one side while the eyes move in the opposite direction, demonstrating that the pathways between the vestibular system and the eye muscles are intact.

In an unconscious child, particularly when assessing for neurological function, this reflex is a significant indicator that the brainstem is still functioning. While a lack of this reflex might suggest severe brain injury or possible brainstem dysfunction, its presence is reassuring and aligns with a more stable neurological status. This reflex is a part of the brain's basic functions, showing that some level of neurological activity is still present, even when the child is not conscious.
