The efficacy of amblyopia treatment depends on the timing of treatment. Children with amblyopia will achieve satisfactory results if they are treated promptly and effectively before the age of 6. Therefore, early detection and early treatment are crucial for amblyopia. There are two key aspects of amblyopia treatment: firstly, the pupil must be dilated and if there is refractive error, the first thing is to get a pair of suitable glasses and insist on wearing them; secondly, various treatments are done under the guidance of an ophthalmologist, i.e. training the amblyopic eye and promoting vision improvement. The effectiveness of the treatment and the speed of cure depend on the compliance and persistence of the parents of the child. The best age for amblyopia treatment is preschool, and the younger the child, the better the outcome and the shorter the course of treatment, and there is basically no hope of curing amblyopia when treatment begins after the age of 12. Amblyopia is a developmental eye disease, and the treatment process is actually a process of promoting the continuous development of visual function. The third phase of the visual system (the plastic phase) is before the age of 12. During the sensitive period, certain eye diseases can cause amblyopia, and at the same time, this is the sensitive period for amblyopia treatment. As sensitivity decreases with age, so does the effectiveness of amblyopia treatment. After the sensitive period, there is no hope of curing amblyopia. Early detection and treatment is the key to a good cure. 1-3 year olds with amblyopia are difficult to treat with conventional treatments, and dilated eye exams require appropriate cooperation from the child. However, this period is the best time to treat amblyopia. An experienced clinician can take appropriate measures to begin treatment based on some of the clinical characteristics of the child. Based on the degree of refractive error of the child, the nature of the strabismus, the state of eye movements, the nystagmus or not, and the masking method, the doctor is able to roughly determine the visual acuity of the two eyes and the difference in visual acuity between the two eyes. Based on this information, appropriate treatment measures such as correction of refractive error, optical suppression therapy, pharmacological suppression therapy, and masking method are selected. after the age of 3, conventional treatment methods can be selected. Can amblyopia be cured? What is the cure rate? Clinical experience at home and abroad proves that amblyopia can be cured. As long as early detection, early treatment, proper guidance from doctors and active cooperation between parents and children are followed. With active treatment and regular follow-up, the expected results can be achieved. How long does it take to cure amblyopia? Amblyopia is a developmental eye disease, and the process of treatment is to promote visual development, so the course of treatment for amblyopia is relatively long. Some clinical studies have shown that it takes about 16 months on average to cure amblyopia. In mild cases, the disease can be cured in a few months; in severe amblyopia, or in children who cannot actively cooperate with doctors, the cure time is longer, some 2-3 years, some 5-6 years, and some cannot even be cured, as long as the child, parents and doctors actively cooperate, within a certain period of time, amblyopia can be cured. Why do some patients cover one eye when treating amblyopia? The eye with better vision is called the dominant eye; and the eye with lower vision is called the inferior eye, i.e. the amblyopic eye. In daily life, competition occurs between the two eyes, and the dominant eye is able to suppress the amblyopic eye, which exhibits an inhibited state. Animal experiments have shown that masking the dominant eye is required to restore normal vision in the amblyopic eye. In order to remove the inhibition of the amblyopic eye by the dominant eye, the most common clinical treatment is traditional masking therapy, which aims to eliminate the inhibition of the amblyopic eye by the dominant eye. By adhering to masking therapy and combining it with other treatments, the vision of the amblyopic eye will continue to improve and finally achieve a cure.
