The Importance of Infant Vision Examination in Dalian Eye Hospital
Eyes are the window for infants to perceive the world, and good eyesight is crucial for infants' development. However, the infant's vision develops rapidly in the first few months after birth, so it is necessary to have an early visual examination. Dalian Eye Hospital provides comprehensive infant vision inspection services to ensure the health of infant vision. So, when should the baby's eyesight be checked? This article will elaborate on the characteristics of infant vision development, examination methods, examination time and importance.
Characteristics of infant vision development
The baby's vision gradually develops from birth, and it begins to stabilize about 3 months later. Newborns have weak vision, can only perceive highly contrasting objects, and are sensitive to color. With the growth and development of the baby, the processing ability of the brain and eyes to visual stimuli gradually improves. The baby begins to notice distant objects and can track moving objects. By the age of 3, the development of the baby's eyeball and optic nerve is basically completed, and the vision reaches the adult level.
According to the characteristics of infant visual development, we can learn that in the first three months of the baby's life, visual examination is mainly to observe the baby's response to highly contrasting objects, such as black and white stripes or moving toys. After 3 months, gradually guide the baby to pay attention to distant objects and observe whether it can track moving objects. Through these observations and measurements, we can preliminarily judge the visual development of infants.
Method of infant vision examination
Dalian Eye Hospital provides a variety of visual examination methods for infants. The most common methods are visual evoked potential (VEP) and electrophysiological examination. Visual evoked potential examination is a method to assess the visual development of infants by recording the electrical signals of their visual cortex. This examination does not require the cooperation of the baby, and only needs to attach the electrode to the baby's head skin, which is very safe. Electrophysiological examination can judge the visual development of infants by measuring the electrical signal of their eyes. This method requires high cooperation of infants.
In addition, infants' visual development can be preliminarily evaluated by observing their responses to specific visual stimuli. The doctor will use high contrast objects such as black and white stripes or color toys to arouse the baby's interest, observe the baby's eye movement and blink and other reactions, and judge the baby's vision level from them.
Time of infant visual examination
According to the characteristics of infant vision development and medical requirements, the best time for infant vision examination is to conduct preliminary screening within one month after birth, and then conduct further examinations at three months, six months, twelve months and two years of age.
The primary screening for one month is mainly to observe the baby's response to highly contrasting objects, such as black and white stripes. At 3 months, the infant's vision has developed significantly, which can gradually guide the infant to pay attention to distant objects and judge whether it can track moving objects. At 6 months, the baby's vision further developed, and its reaction to colored objects can be observed. At 12 months, the infant's vision was basically stable, and a more comprehensive vision examination could be carried out. At the age of 2, the infant's visual acuity can be preliminarily evaluated by comparing it with that of adults.
Summary
The time and method of infant vision examination is very important to ensure the development of infant vision. Dalian Ophthalmology Hospital provides professional infant vision examination services, aiming at early detection and intervention of infant vision problems to ensure their healthy growth. Through preliminary screening and further visual examination, the infant's visual development can be comprehensively evaluated, and relevant treatment and rehabilitation training can be given when necessary. Parents should actively cooperate with the doctor's inspection and guidance, and pay close attention to the baby's vision health.
