Parents are the culprits of children’s high myopia

Abstract: there are 1.6 billion people with myopia in the world, and 600 million in China, accounting for 1 / 3 of the world. The data show that myopia has become the main cause of visual impairment, and its prevalence rate continues to rise, which is expected to reach 2.5 billion people in 2020.

parents are the culprits of children’s high myopia. Parents’ indifference and inaction cause children to miss the early detection and control of myopia. Led to the outbreak of myopia in China. Parents should find their children’s myopia in the early stage and see a professional optometry center or professional ophthalmology.

there are 1.6 billion people with myopia in the world, and 600 million in China, accounting for 1 / 3 of the world. The data show that myopia has become the main cause of visual impairment, and its prevalence rate continues to rise, which is expected to reach 2.5 billion people in 2020. According to statistics, almost all children with high myopia have a pair of “irresponsible” parents behind them. Some parents even think that children’s myopia is pseudomyopia, or give their children a pair of glasses at will. Once children’s myopia rises to five or six Baidu, they often regret it.

what are the early signs of myopia in children? All parents should look at

and

. The high incidence age of myopia in children is 8-14 years old, and there will be some signs of myopia in the early stage. If parents carefully observe their children’s performance in learning and daily life during this period, it may be an early sign of myopia.

I. often squint when looking at objects: myopic patients often squint when looking at things, because the eyelids can block part of the pupils when squinting, which can reduce the scattering of light, so as to temporarily improve and improve their eyesight. Therefore, when your child often squints at objects, it should be considered that he may have early myopia.

II. Frequent blinking: frequent blinking can alleviate myopia and enhance vision to a certain extent. Therefore, when your child has the symptoms of frequent blinking, you should consider whether he has early myopia.

III. often rub eyes: when some children can’t see objects clearly because of myopia, they often rub their eyes with their hands in order to better see objects. Therefore, when you find that your child often rubs his eyes, you should take him to the hospital to check his eyesight in time.

IV. often look at objects with their heads tilted: some children with early myopia often look at objects with their heads tilted. This is because looking at objects askew can reduce the impact of scattered light on their vision. Therefore, when you find that your child often looks at objects with his head tilted, be sure to take him to the hospital to check his eyesight, and correct his wrong posture when looking at objects, so as not to make him form the habit of looking at objects with his head tilted.

V. When looking at things, keep your eyes close to things: when your child looks at objects, he always keeps close to objects. When reading and writing, he often complains that the light in the room is too dark, take into account that your child may suffer from myopia.

6. Often read wrong people or can’t see clearly: when your child often doesn’t say hello to acquaintances, often trips or bruises by things when moving in the dark, or often can’t see the handwriting written on the blackboard, you should also consider whether your child has myopia.

when parents don’t care and myopia develops into high myopia, high myopia can be inherited. Parents are highly myopic, and the proportion of children’s myopia is 30%, while parents are highly myopic, and the proportion of children’s myopia has soared to 81%. Coupled with China’s education system, the proportion of children’s myopia is infinitely close to 100%. Now do not control, after the child becomes highly myopic, all kinds of genetic children and grandchildren are infinite.

generally myopia will not develop in adulthood, and those who continue to develop after the age of 25 are called progressive myopia.

and

are diopters from now on. They are called high myopia because they all exceed 600 degrees.

and

are also called pathological myopia or degenerative myopia because these myopia have ocular pathological changes.

almost all high myopia have axial growth and significant thinning of sclera at the posterior pole of the eye. The main pathological changes are atrophy and thinning of retina and choroid, which are aggravated year by year.

and

have many serious complications, most of which can cause blindness. They are the sixth blinding disease in China.

almost all high myopia have axial growth and significant thinning of sclera at the posterior pole of the eye. The main pathological change is atrophy and thinning of retina and choroid, which is aggravated year by year. Therefore, it produces many serious complications, most of which can cause blindness. It is the sixth blinding disease in China.

the main complications are:

retinal detachment

are the most common complications of myopia.

due to the elongation of ocular axis and intraocular dystrophy in myopia, cystic degeneration and lattice degeneration often occur around the retina. The retina in the degeneration area is very thin and prone to perforation. Some have been perforated and formed in sexual holes. In addition, vitreous liquefaction and increased activity lead to detachment of the traction retina. In retinal detachment, 70% are myopia.

cataract

myopia has abnormal intraocular nutrition metabolism, which changes the capsular permeability of the lens, gradually produces turbidity due to lens nutritional disorder and metabolic disorder, and gradually reduces vision, resulting in concurrent cataract. This kind of cataract develops slowly, mainly core opacity and posterior capsule opacity.

macular hemorrhage and macular degeneration

myopia has poor ocular blood supply and retinal ischemia. The retina produces a kind of neovascular growth factor. These factors make subretinal neovascularization grow. These neovascularization tube walls are very thin and easy to rupture and bleed. After bleeding, macular hemorrhage is formed. After the bleeding is absorbed, the new blood vessels can rupture and bleed again. After multiple bleeding, short marks are formed locally, causing macular degeneration, which permanently damages vision.

vitreous liquefaction denaturation

vitreous is colorless and transparent jelly. When the eyeball of myopia increases, the vitreous body will not increase again, so the vitreous body can not fill all the space in the eye, resulting in liquefaction
