Parents and friends, do you all know? Our babies’ vision is only photopic at birth, that is, they can just see light or can only see very large things vaguely, and from the moment they are born, their vision starts to develop by leaps and bounds. Most children follow the normal vision development process and gradually develop to a normal vision level. However, there are some diseases or eye conditions that can affect your baby’s vision development, and sometimes these diseases quietly affect our children without our knowledge. Before the age of 12 is the sensitive period of children’s visual development, especially in the first 6 years of life is the stage of rapid development of the visual system, in this stage, any adverse factors can affect the visual development of children, so that their development is delayed and lead to amblyopia, which will have an impact on their future life and work. Early detection and reasonable treatment can minimize or minimize the damage to vision. Therefore, it is crucial to evaluate your baby’s vision as early as possible, especially to understand whether your baby’s vision is balanced and consistent in both eyes. Amblyopia is one of the eye diseases that seriously affects the development of children’s visual function. Early detection and reasonable treatment can minimize or avoid damage to vision. Since infants and young children are limited by their cognitive ability to correctly identify visual acuity charts and perform other psychophysical tests, it is important to perform objective visual acuity assessment in children. The visual evoked potential (VEP) is an electrical response to a visual stimulus recorded on the skin surface of the head in the occipital visual center. it primarily reflects the effectiveness of the cone cells in the center of the retina at 6-10 degrees and is not dependent on the subjective response of the subject, thus providing the maximum objective response of the visual system. the VEP provides a rapid method of visual acuity screening and requires a lower level of patient cooperation than other examination methods. Some investigators have found the VEP technique valuable in assessing visual acuity and contrast sensitivity in infants and children. VEP has been used in a wide range of clinical applications, such as observation of the efficacy and prognosis of amblyopia treatment in children, diagnosis and prognosis of cortical blindness, prediction of visual acuity after congenital cataract surgery, diagnosis of multiple sclerosis, optic neuritis, Leber and other diseases. The examination is painless and the child only needs to watch the TV screen for about 10 minutes to obtain the objective visual acuity of the child, which is very meaningful for the diagnosis, efficacy observation and prognosis assessment of the disease. For uncooperative younger children and children with intellectual disabilities who cannot cooperate, flash VEP can address the child’s active nature. The VEP can be performed while your baby is sleeping, providing a timely and early understanding of your baby’s visual development and laying a good foundation for further development. Parents, do you want to know about your baby’s vision and visual development? Do you want to record your baby’s visual development on the growth curve of your baby? Give your baby a “vision” check!
