Abstract: the phenomena of blurred vision, dry and sore eyes, difficulty in concentrating, irritability and even dizziness caused by myopia will make children pay 30% more time and mental labor than children with normal vision, and spend longer time on learning.
summer vacation is coming soon. Do parents and children know that summer vacation is the best time for vision training and recovery?!
according to the degree of myopia, Clinically, myopia is divided into low myopia (below 300 degrees), moderate myopia (300 ~ 600 degrees) and high myopia (above 600 degrees). The etiology, pathogenesis, treatment and prevention of high myopia are different from those of general myopia. For example, the heritability of high myopia is obvious, the age of myopia is earlier, and the degree of myopia increases rapidly. The degree of myopia will increase in adulthood (generally, the increase of myopia is not obvious or will not increase in adulthood). Because high myopia is often accompanied by changes in the axial length of the eyeball (that is, the increase of the anterior and posterior diameter of the eyeball), the retina and choroid of high myopia will have lesions, resulting in many serious complications. Therefore, high myopia is also known as pathological myopia, malignant myopia, degenerative myopia, progressive myopia or genetic myopia. Even wearing glasses, it can not be corrected to 1.0, This will seriously affect the study and life of patients.
what are the fundus lesions of high myopia?
flying mosquito disease:
patients with high myopia often have dark shadows floating in front of their eyes with the rotation of their eyes, just like mosquitoes and flies flying and not when grasping with their hands. This is mainly due to the liquefaction of the normal colloidal structure of the vitreous, that is, the liquefaction of the vitreous. Sometimes vitreous liquefaction can be accompanied by “posterior vitreous detachment” (under normal circumstances, the posterior vitreous boundary is connected with the retina. When the posterior vitreous boundary leaves the retina after vitreous liquefaction, it is called posterior vitreous detachment in medicine).
visual distortion can occur when high myopia causes macular lesions, such as macular anterior membrane, submacular hemorrhage, macular splitting, macular hole, macular detachment, etc. When patients look at things, straight things become curved, square things become distorted, things become larger or smaller, etc. The peripheral vision of
mean that when you look at things, you can’t see things in some places around, and there are fixed dark areas in some parts. In addition to optic nerve papilla and optic neuropathy, if there is a peripheral viewing defect in high myopia, it is mostly caused by retinal detachment. You should see a doctor in time. Because the external object image forms an inverted image on the retina, if nothing can be seen above, the patient’s lower retina is generally detached. If you can’t see below, there is retinal detachment above. Other known hazards of

myopia. Parents are highly myopic, and the proportion of children’s myopia is almost 100%. If treatment is not taken in time, they will become slaves of glasses for generations.
