When does the doll's eye reflex disappear?
My baby is now one year old, and I have noticed that he still has doll-like eye reflexes.
I would like to know when this phenomenon will typically disappear, or should we see a doctor now? Thank you for your response!

Hello: I would like to clarify if what you refer to as the "doll's eye reflex" is indeed the doll's eye reflex/sign? The doll's eye reflex is a normal physiological phenomenon, which refers to the eyes moving in the opposite direction when the head is passively turned from side to side, meaning the eyes tend to remain focused on the original point of gaze.
If the eyes move along with the head, indicating that they do not move independently, this may suggest a possible impairment of brainstem function.
If you are referring to a different condition, please feel free to ask again or discuss directly with a physician.
Wishing you health and peace.
Thank you for your message!

More Info
The "doll's eye reflex," also known as the oculocephalic reflex, is a normal physiological response observed in infants. This reflex occurs when the head is turned to one side, and the eyes move in the opposite direction, maintaining the gaze on a fixed point. This reflex is particularly prominent in newborns and typically begins to diminish as the child grows and develops more voluntary control over their eye movements.
In most infants, the doll's eye reflex is expected to fade by the time they reach about 6 months of age. By this age, babies usually start to gain better control over their eye movements and begin to exhibit more voluntary tracking of objects. However, it is important to note that there can be variations in development among individual children. Some may retain this reflex slightly longer, but if it persists beyond the age of 1 year, it may warrant further evaluation.
If your one-year-old child is still exhibiting the doll's eye reflex, it is advisable to consult a pediatrician or a pediatric ophthalmologist. While the presence of this reflex alone may not indicate a serious issue, it is essential to rule out any underlying neurological concerns, especially if there are other signs of developmental delays or abnormal eye movements. A healthcare professional can conduct a thorough examination and provide guidance based on your child's specific situation.
In addition to the doll's eye reflex, it is also important to monitor other aspects of your child's visual and neurological development. For instance, observe how your child interacts with their environment, their ability to track moving objects, and their responsiveness to visual stimuli. If you notice any unusual behaviors, such as persistent eye crossing, lack of visual engagement, or difficulty focusing on objects, these could be indicators that further evaluation is necessary.
In summary, while the doll's eye reflex is a normal part of infant development, its persistence beyond the age of 1 year should be assessed by a medical professional. Early intervention can be crucial in addressing any potential developmental concerns, ensuring that your child receives the appropriate support and care as they grow. Always trust your instincts as a parent; if you feel something is not right, seeking medical advice is the best course of action.
