Amblyopia is a loss of visual function in children who, for various reasons, do not receive normal visual stimulation during the aggregation of visual cells in the central macular sulcus during early development and thus fail to develop normally, and the cerebral cortex is unable to obtain clear images. The common causes of amblyopia include high hyperopia, refractive error, high astigmatism, congenital cataract, etc. Amblyopia is not only a problem of the eyes, but also a problem of the development of the cerebral cortex. What is the best time for amblyopia treatment? The best time to treat amblyopia is before the age of 3. For the sake of baby’s eye health, according to the “Technical Specification for Children’s Eye and Vision Care” of the Health and Welfare Commission, babies should have regular eye health checkups at 1 month, 3 months, 6 months, 1 year and once a year after 1 year of age to detect early eye diseases affecting children’s visual development, correct them early, and protect and promote the normal development of children’s visual function. More than 95% of amblyopic children aged 3-6 can be cured, but the cure rate decreases with age, and amblyopia treatment is generally less effective in children over 12 years old. However, with the development of technology, passive cortical learning treatment is available for amblyopic children over 8 years old, making it possible to treat amblyopia in older children and even in adults over 12 years old. Amblyopia treatment methods There are a variety of amblyopia treatments available, but only professional, standardized amblyopia treatment can have real results. At present, amblyopia treatment worldwide is divided into the following three stages: Stage 1: wearing glasses, masking and light stimulation, this stage is suitable for amblyopic children of any age; Stage 2: amblyopia training and vision training program vision therapy, mainly for children over 4 years old, poor binocular vision function, strabismic amblyopia; Stage 3: application of visual psychophysical methods, targeting the cerebral cortex stimulation The third stage is the application of visual psychophysical methods, targeting cortical stimulation, cortical stimulation, and visual perception learning. This stage is suitable for older children with amblyopia and poor treatment results.
