Occurrence and harm of amblyopia
Amblyopia is a common ocular disease in children. The prevalence rate among preschool and school-age children is about 2-4%. In my country, there are 3 There are more than 100 million children, and about 12 million of the 300 million children have amblyopia. Because amblyopia is not as obvious as myopia, many children can't see it at the surface, so they are more likely to be ignored by parents.
Amblyopia is the best-corrected visual acuity in one or both eyes caused by developmental abnormalities (monocular strabismus, great difference in binocular power, etc.) during visual development, which is below the lower limit of normal children's visual acuity at this age, but there is no disease in the eye examination. Amblyopia in children is defined as: (1) Children under 3 years old is less than 0.5; (2) 4-5 years old is less than 0.6; (3) 6-7 years old is less than 0.7; binocular vision difference is more than 2 lines, if this age If your child's best corrected vision drops to these levels, you should consider whether you have amblyopia.
Children with amblyopia have poor corrected vision (that is, they wear the best corrective glasses, but the vision is still poor), they see blurred things, do not have normal stereo vision, and cannot do many tasks that require fine vision and spatial positioning capabilities. There are also many difficulties in study and life, such as lack of three-dimensionality when looking at a microscope, and easy fall when going down the stairs. If there is no effective treatment, it will affect the future college entrance examination and employment. Professor Yang Jiwen, vice president of Liaoning Province of
Aier Ophthalmology Group, said that in addition, amblyopia can also easily cause strabismus, affect the appearance and self-confidence of children, and reduce the quality of life.
