Abstract: the ocular axis of patients with true myopia is significantly longer than the original. According to expert analysis, the degree of myopia increases by 300 degrees for every 1mm increase in the ocular axis in patients with myopia. Generally, myopia below 300 degrees is called low myopia, those between 300 and 600 degrees are called moderate myopia, and those above 600 degrees are called high myopia., Most children’s myopia could have been avoided and recovered, but because parents dragged their children until they couldn’t see the blackboard clearly, it was more than 200 degrees at that time! Then he came to us and asked a really low-level question: can the child fully recover? We can only tell you that if the child has just developed myopia and is treated in time, he can recover quickly. Once the true myopia is formed, it is a flood and beast, with an average annual growth of 50 ~ 150 degrees! Therefore, we must first quickly control the growth of children’s myopia, otherwise children are likely to have high myopia after the age of 18! Therefore, if the child’s vision is found to be abnormal, for example, the vision is between 0.6 ~ 1.0, it needs to be handled quickly, and it is likely to be completely recovered. Myopia has three development stages: 1. In the stage of pseudomyopia, if the spasm of ciliary muscle is relieved by physical methods or other physiotherapy methods, the eyeball can return to its original state, block the development of myopia and prevent the development from pseudomyopia to true myopia. If there is no good prevention and treatment at this time, the retina will stimulate the continuous development of sclera, cause the growth of ocular axis, and gradually evolve into true myopia. Generally, children’s vision is pseudomyopia when it is 0.6 ~ 0.8 (4.8 ~ 4.9), and pseudomyopia becomes true myopia for 1 ~ 3 months., 2. In the stage of true myopia, the ocular axis of patients with true myopia increases significantly than before. According to expert analysis, the myopia degree increases by 300 degrees for every 1mm increase in the ocular axis in patients with myopia. Generally, myopia below 300 degrees is called low myopia, those between 300 and 600 degrees are called moderate myopia, and those above 600 degrees are called high myopia. The development of myopia in young children is characterized by fast growth, with an average growth of 50 ~ 150 degrees, until the age of 18! Some have an annual growth rate of more than 200 degrees!, 3. In the stage of high myopia, with the increase of ocular axis, the eyeball of young children with myopia continues to expand. It can be seen that the eyeball is much larger than the normal eyeball in the eyeball specimen. In the process of eyeball enlargement, the sclera and choroid can grow continuously according to the signal requirements inside the eye, but the retina cannot grow with it. In order to stick to the increased sclera and choroid, the retina will have many cracks or lattice degeneration around the retina, resulting in early lesions for retinal detachment in the future. There are 4 complications in myopia. Attention should be paid to the incidence of open angle glaucoma in cataract and glaucoma. The incidence rate of open angle glaucoma is 6 to 8 times higher than that of normal persons. However, glaucoma is often obscured by symptoms of high myopia due to its clinical symptoms. High myopia with posterior pole cortical opacity of crystalline body is also common, and the dark adaptation time is relatively prolonged because the pathological changes of pigment epithelial cells in patients with high myopia affect the reaction process of photochemical changes of visual cells. Flying mosquito disease high myopia can produce real vitreous degeneration or liquefaction, causing obvious flying mosquito disease. Consciously float the light, spark, flash or shadow in front of you. Posterior scleral staphyloma is mainly characterized by the backward expansion of the posterior pole of the eye, which is the degeneration and atrophy of the nerve and the retina around the macula, and the decline of corrected visual acuity. The higher the degree of myopia, the higher the incidence., Retinal degeneration, hemorrhage, hole and detachment due to the lengthening of the ocular axis, the thinning of the posterior half of the eyeball, atrophy and degeneration of the retina and choroid, there are holes, leading to hemorrhage and retinal detachment with different ranges, resulting in visual loss. In addition, macular degeneration is also the biggest risk of high myopia, which shows visual distortion, vision decline, and eventually lead to blindness.,

Therefore, if the child’s vision is found to be abnormal, for example, the vision is between 0.6 ~ 1.0, it needs to be handled quickly, and it is likely to be completely recovered. Myopia has three development stages:
1. In the stage of pseudomyopia,
if the spasm of ciliary muscle is relieved by physical methods or other physiotherapy methods, the eyeball can return to its original state, block the development of myopia and prevent the development from pseudomyopia to true myopia. If there is no good prevention and treatment at this time, the retina will stimulate the continuous development of sclera, cause the growth of ocular axis, and gradually evolve into true myopia. Generally, children’s vision is pseudomyopia when it is 0.6 ~ 0.8 (4.8 ~ 4.9), and pseudomyopia becomes true myopia for 1 ~ 3 months.
2. In the stage of true myopia,
the ocular axis of patients with true myopia increases significantly than before. According to expert analysis, the degree of myopia increases by 300 degrees for every 1mm increase in the ocular axis in patients with myopia. Generally, myopia below 300 degrees is called low myopia, those between 300 and 600 degrees are called moderate myopia, and those above 600 degrees are called high myopia. The development of myopia in young children is characterized by fast growth, with an average growth of 50 ~ 150 degrees, until the age of 18! Some have an annual growth rate of more than 200 degrees!
3. In the stage of high myopia,
young children with myopia expand their eyeballs with the increase of ocular axis, which is much larger than the normal eyeball in eye specimens. In the process of eyeball enlargement, the sclera and choroid can grow continuously according to the signal requirements inside the eye, but the retina cannot grow with it. In order to stick to the increased sclera and choroid, the retina will have many cracks or lattice degeneration around the retina, resulting in early lesions for retinal detachment in the future. There are 4 complications in myopia. Attention should be paid to the incidence of open angle glaucoma in cataract and glaucoma. The incidence rate of open angle glaucoma is 6 to 8 times higher than that of normal persons.The symptoms are covered up and easy to be ignored. High myopia with posterior pole cortical opacity of crystalline body is also common, and the dark adaptation time is relatively prolonged because the pathological changes of pigment epithelial cells in patients with high myopia affect the reaction process of photochemical changes of visual cells. Flying mosquito disease high myopia can produce real vitreous degeneration or liquefaction, causing obvious flying mosquito disease. Consciously float the light, spark, flash or shadow in front of you. The main manifestation of posterior scleral staphyloma is the backward expansion of the posterior pole of the eye, which is the degeneration and atrophy of the nerve and the retina around the macula, and the decline of corrected visual acuity. The higher the degree of myopia, the higher the incidence. Retinal degeneration, hemorrhage, hole and detachment of
and
due to the lengthening of the ocular axis, the thinning of the posterior half of the eyeball, the atrophy and degeneration of the retina and choroid, there are holes, resulting in hemorrhage and retinal detachment of different ranges, resulting in visual loss. In addition, macular degeneration is also the biggest risk of high myopia, which shows visual deformation, vision decline, and eventually lead to blindness.
and
high myopia can’t do strenuous exercise because of complications, so it will be limited to find jobs and objects in the future. This is why young children with true myopia still need prevention and control even though they know that some can’t recover completely.
