The term "doll's eye-indicator" refers to a medical sign where the eyes stay fixed in place while the head is moved, indicating neurological damage. Brainstem reflexes are responsible for keeping the eyes steady. Synonyms for this sign include "oculocephalic reflex," "vestibulo-ocular reflex," and "brainstem reflex." The oculocephalic reflex is a result of the vestibular system, which detects head movements and sends signals to the eye muscles. The vestibulo-ocular reflex is critical for maintaining visual focus while the head moves. Brainstem reflexes are essential of the neurological assessment and help clinicians diagnose various disorders affecting the brainstem.
