How long does the "doll's eye" phenomenon typically last in newborns?

The "doll's eye" phenomenon, also known as the oculocephalic reflex, is a normal neurological response observed in newborns. It refers to the eye movement that occurs when the head is turned while the eyes remain fixed on a point, giving the appearance that the eyes are 'tracking' or 'moving' like those of a doll. This phenomenon typically lasts for about 10 days in newborns as their neurological system is still maturing during this early period. After this time frame, the reflex diminishes as the infant's nervous system becomes more developed and their visual tracking skills improve.

Recognizing the duration of the "doll's eye" phenomenon is important for assessing the neurological development of neonates. It helps nurses and healthcare providers differentiate between normal and abnormal neurological responses in newborns. When addressing the developmental milestones of newborns, it’s essential to monitor for such reflexes within expected timelines to ensure proper growth and neurological function.
