The ultimate goal of amblyopia treatment is not only to have good monocular vision, but also to have a higher level of binocular vision, not just to improve the vision to normal means that amblyopia treatment can be finished, amblyopia treatment is divided into two steps: the first step is to simply improve monocular vision, because a lot of amblyopia needs to be masked, so it can’t take into account binocular harmony and cooperation: the second step is to exercise the ability to coordinate the two eyes after the binocular vision has reached normal, including simultaneous vision, fusion and stereo vision. The second step is to improve the coordination between both eyes and establish binocular vision, including binocular simultaneous vision, fusion and stereoscopic function, especially stereoscopic vision is the only way to have the sense of spatial distance and complete many fine movements, which is a must for many fine work. Functional abnormalities caused by amblyopia are multi-faceted, and among them, visual acuity and stereo vision have a greater impact on the quality of visual function, and their performance is relatively obvious and direct, and in practice, these two items become the intuitive indicators of amblyopia diagnosis and treatment. Meanwhile, since stereoscopic vision is based on a certain level of monocular visual acuity in both eyes, so “(best-corrected) visual acuity is lower than the lower limit of the normal reference value for children of the same age” is regarded as the diagnostic criterion of amblyopia, but it does not mean that the restoration of visual acuity is equal to the cure of amblyopia. The treatment of amblyopia consists of two aspects: one is to improve the visual acuity of the amblyopic eye, and the other is to rebuild and restore binocular visual function. Binocular visual function includes the following three levels: 1. Simultaneous vision function – the ability of both eyes to see the same target object at the same time; 2. Fusion function – the ability of both eyes to merge the two images formed by the same target object seen into one; 3, Stereopsis – the ability of both eyes to judge the level of the target object and the perception of spatial distance. The ultimate goal of amblyopia treatment is not only to improve the visual acuity of the amblyopic eye, but also to strive for the best possible binocular vision at all times. The reconstruction and restoration of binocular vision is not inevitable with the improvement of monocular vision, but also requires the appropriate technical interventions, including testing, training, evaluation, etc. Therefore, the parents of the patients should cooperate with the doctors in the treatment of amblyopia. Therefore, parents should pay attention to two points when cooperating with doctors to implement amblyopia treatment for their children: firstly, in the early stage of amblyopia treatment, the improvement of monocular or binocular visual acuity is the main focus; secondly, in the late stage of amblyopia treatment, don’t be satisfied with the improvement of visual acuity of amblyopia eye or the restoration of amblyopia eye, and let the “victory” go over your head, but also do not lose the opportunity to implement binocular visual function testing and training for your child according to the doctor’s prescription. Secondly, in the late stage of amblyopia treatment, we should not only be satisfied with the improvement and recovery of visual acuity of amblyopia eyes, but also implement the testing and training of visual function of both eyes according to the doctor’s prescription, so as to maximize the recovery of visual function of both eyes, and to let the children get clear, comfortable and lasting healthy vision.
