Vision screening requires the cooperation of the person being examined and requires the person to have not only the ability to recognize the visual markers but also the ability to express them credibly. This makes it difficult for children, especially infants, to have their vision examined. How can a non-expressive infant know his or her visual acuity? Vision screening, which is widely available in maternal and child health centers, provides some help in understanding the vision of infants and children. It is a photographic examination that does not require the child’s cognitive or expressive abilities, but simply requires the child to look at the examiner head-on. It is easy to operate, takes a short time, and does not require the child’s patience. This is the reason why this test is so widely used. Because the main cause of vision is refractive problems, or what we usually call myopia, hyperopia, astigmatism, etc., the main job of the vision screener is to screen the child’s eyes for refractive problems, in other words to see if the refractive state of the child’s eyes is within normal limits. If the infant’s vision screening results are not within the normal range, the health care provider may recommend that the parents take the child to an ophthalmologist. Often the ophthalmologist will recommend that the child have a dilated eye exam. However, the need for dilating medication and the need to sedate the child before the test because he or she is uncooperative can make parents apprehensive about the test. My advice is to repeat the test several times if the screening results are abnormal. After all, vision screening is a screening test, not an accurate test, and its results are not very accurate, especially for children who are uncooperative. Repeating the test several times will help us determine the reliability of the results. If the data obtained from multiple screenings are relatively similar, then it can be judged to be more reliable, suggesting the need for an eye exam. Although it may be more difficult to screen infants and children than adults, it is necessary to have a timely and accurate understanding of the condition, especially for children with significant abnormal screening results. For children with large deviations from repeated screening results, especially those with normal screening results, it is possible to observe the condition first, review it regularly, and have the vision exam done in a timely manner when the child reaches an appropriate age for vision exams.
