1.What is amblyopia? Amblyopia refers to eyes without obvious organic pathology, and corrected visual acuity is less than 0.9. At present, China’s amblyopia diagnosis criteria are: 1. corrected visual acuity <0.9 2. difference in visual acuity between the two eyes ≥ 2 lines. Amblyopia is an eye disease that seriously endangers the visual function of children. If amblyopia in children is not detected and treated early, it will lead to low vision in one or both eyes, seriously affecting binocular vision and leading to fusion loss and stereo blindness. Amblyopia is a curable disease if it occurs during the sensitive stage of visual development. There are many causes of amblyopia, including pediatric strabismus, high hyperopia, myopia and astigmatism, congenital cataract, severe ptosis, and congenital optic nerve hypoplasia. 2, how to confirm the diagnosis of amblyopia: amblyopia must be diagnosed atropine dilated pupil optometry, this slow dilated pupil optometry, to use 3-5 days atropine eye ointment, to regular children's optometry institutions for dilated pupil optometry, 21 days later, the pupil completely recovered, retesting, to determine the final optometric results. If the child's corrected visual acuity is <0.9 or the difference in visual acuity between the two eyes is ≥2 lines, then amblyopia can be diagnosed. 3. Is amblyopia the same as myopia? Myopia tends to occur in school age and adolescents, is due to eye adjustment muscle ciliary muscle over tension or genetics and other reasons caused by the axis of the eye becomes longer to see far unclear, see near clear eye disease, and children can wear glasses after corrected vision can be restored to normal; while amblyopia is mostly seen in preschool, is a visual function development delay, disorder, often accompanied by strabismus, high refractive error, wearing glasses vision can not be corrected to normal eye disease. The vision is not good at distance and near. There is a fundamental difference between the two diseases. 4. Can amblyopia be cured? Some people think that amblyopia should be treated when the child is older, then the child also understands, the treatment is also easy to cooperate, this view is very wrong, the treatment of amblyopia and age is closely related, the younger the age, the better the effect. This is because children's visual function is unstable during their visual development, and it is easy for amblyopia to occur as well as to return to normal. Some studies have shown that the critical period is within 2 years old, the sensitive period is before 6-8 years old, the treatment effect is extremely poor after 10 years old, and it is almost hopeless to treat after 12 years old. And the treatment of amblyopia is not a one-time thing, is a protracted war, preschool children have more time to cooperate with the treatment, after school certain treatment will be affected by learning, often bring difficulties to the treatment and affect the effectiveness. 5.Can I treat amblyopia without glasses? Amblyopia is mostly accompanied by refractive error, and amblyopia can only be improved if glasses are worn to correct refractive error and amblyopia training is carried out at the same time, so that clear images repeatedly stimulate the retinal gaze center and improve visual sensitivity, so it is necessary to wear glasses to treat amblyopia. Currently there are many "new amblyopia treatment methods" on the market, such as ear acne, laser, Chinese medicine, massage, physical therapy, etc. Treatment manufacturers often require children to remove their glasses for treatment, which is completely wrong, removing glasses will image the child's normal visual function development. 6.How is amblyopia treated? What are the common treatment methods? The key to amblyopia treatment is accurate optometry, children also need to dilate the pupil for optometry and wear appropriate glasses, on this basis, the treatment mainly includes the following methods: (1) traditional masking method + fine visual homework: cover the eye with good vision, force the amblyopic eye (eye with poor vision) to see, while doing fine visual homework, such as: wearing beads, using the amblyopic insert board for training, stimulating the development of the optic nerve system development, so that the amblyopic eye can improve its visual acuity. This method is simple and easy to implement, and is suitable for strabismic amblyopia and refractive amblyopia, with reliable results. (2) Brain imaging network amblyopia treatment, amblyopia treatment instrument, multimedia vision enhancement CD-ROM training, etc., is a newer visual therapy technology, the child is interested, the treatment effect is good. 7.Can amblyopia glasses still be removed? This question is also a common concern of parents of children with amblyopia, in fact, most of the glasses of children with amblyopia can be removed when they grow up. This is because children with amblyopia are more likely to have combined hyperopia, and as children with amblyopia grow older and their eyes develop, the degree of hyperopia will gradually decrease, and the degree of glasses will also decrease, and their vision will gradually return to normal, and their glasses will be taken off. Of course, if the cured amblyopic child does not pay attention to eye hygiene during development, and causes myopia, it will be necessary to wear myopic glasses again.
