Once the diagnosis of amblyopia is confirmed, it should be treated as soon as possible, because it is very difficult to treat amblyopia when the age exceeds the sensitive period of visual development. The earlier the detection and treatment, the better the outcome and the shorter the time. On the contrary, the treatment is ineffective and the time is long. Amblyopia treatment methods are as follows: 1. Covering therapy: Covering the dominant eye and forcing the use of the amblyopic eye is by far the most effective method of treating monocular amblyopia. Treatment time and efficacy are highly related to the age of the child being treated, the younger the age, the better the efficacy and the shorter the time will be. The review cycle after treatment is once a week for one-year-old children to see if they have achieved binocular vision balance; once every two weeks for two-year-olds; and once a month for four-year-olds. Enough to show that the age of treatment has a great relationship with the efficacy and cure time. 2.Suppression therapy: It is suitable for children with low to moderate monocular amblyopia, and children with poor effect of masking therapy. The study found that the treatment time and efficacy of suppression therapy for children aged 3-7 years old with amblyopia and masking therapy are similar. Again, the younger the child, the earlier the treatment, the better the effect and the shorter the time. 3, visual stimulation therapy: can supplement masking therapy to shorten the time of amblyopia treatment. 4, integrated therapy: for some children, can be integrated masking method, suppression therapy, visual stimulation therapy, auxiliary fine training together, may achieve better results, the treatment time may also be shortened. The earlier the treatment begins, the better the outcome and the shorter the treatment time. The time to cure amblyopia is determined by the time and method of detection and treatment.
