Low visual acuity (not decrease) in one or both eyes due to congenital factors or insufficient visual stimuli (including photopic and form) entering the eye during the critical period of visual development, depriving the macula of the opportunity for clear imaging, or unequal visual input from both eyes, causing competition between clear and blurred objects. In layman’s terms: amblyopia is an eye without organic changes, according to the degree of optometry to correct vision, but the corrected vision does not reach the standard of normal peers, usually to 0.9 as the standard. I, the harm of amblyopia Amblyopia is a visual dysfunction, not only affects the child’s future education, employment and work, so that they can not engage in promising professions (such as soldiers, pilots, surgeons, etc.), but also brings great inconvenience to life, more serious can also lead to lifelong low vision, can not form stereo vision, with any glasses can not achieve normal vision. Parents should take their children to the hospital for examination if they find the following manifestations in their children: near vision, nystagmus, abnormal head position (oblique), squinting at TV, loneliness, and the phenomenon of “blindness” (infants around 3 months old do not look at the target without moving their eyes with people or objects). (3 months of age). Treatment of amblyopia Amblyopia is mainly formed at the age of 1 to 3 years, so in principle, the earlier the treatment of amblyopia, the better. However, since it is difficult to detect and diagnose amblyopia before the age of 3, treatment should be started at the age of 3 to 6 as much as possible, but the effect is very poor beyond the age of 6, and it is difficult to achieve results for those who are older than 12. Do not think that amblyopia is not a disease or is a minor disease. Even if you have the illusion that your child will grow up and get better on his or her own, untimely or delayed treatment will lead to lifelong hatred. The treatment of amblyopia is not something that happens overnight. During the longer treatment process, parents should not only accompany their children to the treatment, but also cooperate with the doctor to do a lot of auxiliary exercises for their children, and they should do it together with their children so that the results will be better. At present, the common methods of treating amblyopia are masking therapy, red light flash therapy (red flash), Hedinger light brush therapy, visual physiological stimulation therapy (grating), posterior image enhancement therapy and home fine work, etc. Due to the complex pathogenesis of amblyopia, the use of comprehensive therapy is more effective than single therapy, significantly shortening the course of treatment and improving the efficiency and cure rate of amblyopia treatment. Comprehensive therapy is especially helpful for older children with moderate or severe amblyopia.
