The treatment effect of amblyopia is closely related to the age, the younger the treatment effect, the best effect before 8 to 9 years old; on the contrary, if the treatment time is missed, the treatment is not effective. If the treatment is missed, the treatment will not be effective. Over 12 years old, the treatment effect is very poor. Therefore, amblyopia must be detected and treated early. Amblyopia is the lack of sufficient visual stimulation during the critical period of eye development in children, so that the development of visual function is inhibited, forming amblyopia. Amblyopia is considered to be caused by a lack of sufficient visual stimulation during the critical period of development of the child’s eyes. Due to the decrease of binocular (or monocular) vision, there is no perfect binocular vision function and fine stereo vision, if not treated in time, the visual cells and nerves will decline and the vision will be permanently low, the stereo vision is blurred and cannot accurately determine the orientation of objects, which will affect the child’s healthy growth and future quality of life. Therefore, if your child has some early symptoms, you should take your child to the hospital for refractive and fundus examinations. For example, does the child like to squint or squint at things? Does he or she move more slowly than his or her peers? When walking normally, has he/she suddenly fallen? Does your child often feel sore and swollen eyes, blurred eyes, or even shaky scenery? If you have these conditions, it is best to take your child to the hospital for a professional examination, and if conditions allow, to have a vision test every six months. If amblyopia is diagnosed, the earlier the treatment, the better the outcome. Amblyopia can be divided into mild amblyopia (0.6~0.8), moderate amblyopia (0.2~0.5), and severe amblyopia (less than 0.1) according to the degree of corrected vision. Most children with amblyopia can improve their vision to varying degrees after comprehensive treatment and training, and the key is to adhere to treatment even when the child’s eyes are still developing. Treatment of amblyopia generally works best before the age of 8 or 9, and the younger the age, the better the results. The younger the child, the better the results. And it is important to adhere to the course of treatment until it is stable, not intermittent. In addition, amblyopia treatment can be repeated before the child’s vision matures, so it is important to insist on follow-up visits after treatment, once a month for the first 6 months of treatment, and once every 3 months to 6 months thereafter, generally for at least 3 years.
