Abstract: myopia is an organic change of the eyeball. The anterior and posterior axis of the eyeball becomes longer. External objects are imaged in front of the retina through the refractive system of the eye. There is no clear object image on the retina.
myopia has become the biggest “killer” of adolescent health, especially high myopia. A series of fundus complications caused by high myopia can not be solved by optical means or surgery. Therefore, children’s myopia should be controlled in time, so as not to miss the golden period of treatment and develop into high myopia.
pseudomyopia may drag into true myopia
go to the glasses first when you find that your child’s vision drops? This is wrong. Myopia can be divided into true and false. Children under the age of 12 should have mydriatic optometry for the first time to eliminate false myopia. After mydriasis, if the child’s vision returns to normal, it is pseudomyopia.
pseudomyopia is caused by excessive eye use, resulting in continuous contraction of ciliary muscle, excessive regulation, formation of regulatory spasm, increase of lens diopter and unclear vision. It is curable to correct pseudomyopia in time. But if there is no timely treatment, it will become true myopia in the long run. True myopia is irreversible after its formation, and its development can only be controlled in a scientific way. The survey of
shows that the incidence of myopia among urban students aged 6-18 has surged from less than 10% to about 80%. In the coming decades, ophthalmic complications caused by myopia will become the first cause of visual impairment and blindness. Therefore, regular eye examination, scientific prevention of children’s myopia and scientific control of the progress of children’s myopia are very important.
experts remind: myopia generally occurs at the age of 6-10, and the risk of developing into high myopia in adulthood is greatly increased. If measures can be taken to make children’s myopia occur later, progress slower, and the degree will be lower in adulthood.
are used to prevent myopia. Different methods are adopted at different ages. Myopia of
cannot be eradicated, but can only be prevented scientifically. The key period for the prevention and treatment of myopia is 8-18 years old. Children of different ages can take different methods. For primary school children, we should remind them to sit upright and pay attention to controlling the time of using their eyes.
in junior and senior high school, the academic burden is increased, the child’s body is also developing, and the eye axis will also grow. If effective measures are not taken, myopia will increase rapidly. Parents should remind their children to pay attention to eye hygiene and participate in outdoor activities. The growth of
ocular axis is closely related to the occurrence and development of myopia.
myopia is an organic change of the eyeball. The anterior and posterior axis of the eyeball becomes longer. External objects are imaged in front of the retina through the refractive system of the eye, and there is no clear object image on the retina.
China is a large country of myopia. Scientists have been exploring the causes of myopia. Research shows that Chinese Americans have longer axial length than Latino Americans, and axial length plays an important role in the occurrence and development of ametropia.
about 1 / 10 myopia patients have fundus problems.
high myopia (more than 600 degrees) often has fundus diseases, such as maculopathy and retinal detachment, which may lead to blindness. High myopia will affect the vision of the next generation and the quality of China’s future population through genetic mechanism, resulting in a vicious circle that is difficult to crack.
