Experts explain the causes and treatment of myopia in detail

Abstract: some people say that genetic factors account for 60% or more, but the general probability of myopia inheritance is not particularly certain. The heritability of high myopia is recognized. If the degree of myopia in adults is more than 500, it must be hereditary., What causes juvenile myopia and amblyopia?, Cheng Kai: let’s first talk about the problem of myopia. The reasons for the invention of myopia are basically two categories, one is genetic factors, and the other is environmental factors. The causes of amblyopia are different now. There are not only our own situation, but also our environmental factors. For example, when infants and young children just started to give birth, if eye diseases caused the impact of his visual development, amblyopia will be caused. In infancy, some parents’ child rearing habits may also cause some eye diseases., Some people say that genetic factors will account for 60% or even higher, but the general probability of myopia inheritance is not particularly certain. The heritability of high myopia is recognized. If the degree of adult myopia is more than 500, it must be hereditary. If both parents are highly myopic, the child’s heritability is 100%. Of course, it may also be caused by another generation. If one of the parents is highly myopic and the other is normal, the child’s myopia heritability is 50%, but it may not happen., What is the precursor of myopia?, Cheng Kai: if it is congenital axial myopia, it must not have much to do with the influence of the day after tomorrow. For this kind of myopia whose heritability is not very obvious, it is mostly caused by acquired reasons. Its occurrence and development process is a process from scratch, from quantitative change to qualitative change. Let’s first look at the normal visual evolution process of human beings. In ancient times, we all made a living by hunting. We have to look at prey far away. The structure of the eyeball is prepared to see far away; However, in today’s society, most of the things we see every day are within five meters, mainly focusing on proximity., When looking at objects five meters away, the ciliary muscles relax, the crystals tend to be flat, and parallel light is transmitted to the retina. The ciliary muscles contract when they look close, and continuous contraction when they look close all the time, which is prone to spasm, and hypoxia. We call this time the functional compensation period. For example, if you often pull an elastic band, the number of times should have a limit. If it is loose, there will be no tightness. People’s ciliary muscle will do the same. When spasm and hypoxia, the lens can’t accept the domination of the ciliary muscle. At this time, the focus of the visual object will automatically tend to the back of the retina, the eyeball will become larger and the eye axis will become longer. In this way, true myopia is found. In the early stage, it is functional compensation. After a long time, functional compensation will not work. You should look at the distance as far as possible when functional compensation has just appeared in your eyes, so as to restore the regulation function of ciliary muscle. This is your way to alleviate eye fatigue., What harm does myopia do to teenagers?, Cheng Kai: first of all, it brings inconvenience to life. If you have bad eyes when you go to college, you will also be affected when you choose a school. But from a pathological point of view, if the eyes are high myopia, the axial length will become longer and the eyeball will become bigger. At this time, the retina of human being will be thinned, and some retinopathy will easily appear. It will cause the early muddy and the incidence rate of cataract. What causes

can cause juvenile myopia and amblyopia?

Cheng Kai: let’s first talk about the problem of myopia. The reasons for the invention of myopia basically fall into two categories: one is genetic factors and the other is environmental factors. The causes of amblyopia are different now. There are not only our own situation, but also our environmental factors. For example, when infants and young children just started to give birth, if eye diseases caused the impact of his visual development, amblyopia will be caused. In infancy, some parents’ child rearing habits may also cause some eye diseases.

some people say that genetic factors will account for 60% or even higher, but the general probability of myopia inheritance is not particularly certain. The heritability of high myopia is recognized. If the degree of adult myopia is more than 500, it must be hereditary. If both parents are highly myopic, the child’s heritability is 100%. Of course, it may also be caused by another generation. If one parent is highly myopic and the other is normal, the child’s myopic heritability is 50%, but it may not happen.

what is the precursor of myopia?

Cheng Kai: if it is congenital axial myopia, it must not have much to do with the influence of the day after tomorrow. For this kind of myopia whose heritability is not very obvious, it is mostly caused by acquired reasons. Its occurrence and development process is a process from scratch, from quantitative change to qualitative change. Let’s first look at the normal visual evolution process of human beings. In ancient times, we all made a living by hunting. We have to look at prey far away. The structure of the eyeball is prepared to see far away; But in today’s society, most of the things we see every day are within five meters, mainly focusing on the near.

when looking at objects five meters away, the ciliary muscles relax, the crystals tend to be flat, and parallel light is transmitted to the retina. The ciliary muscles contract when they look close, and continuous contraction when they look close all the time, which is prone to spasm, and hypoxia.

You should look as far as possible when functional compensation has just appeared in your eyes to restore the regulation function of ciliary muscle. This is your way to alleviate eye fatigue.

what harm does myopia do to teenagers?

Cheng Kai: first of all, it brings inconvenience to life. If you have bad eyes when you go to college, you will also be affected when you choose school. However, from a pathological point of view, if it is high myopia, the ocular axis may become longer and the eyeball will become larger. At this time, people’s visual acuity will increaseThe incidence rate of cataract is higher than that of the retina.

if myopia is not treated in time, it will lead to many complications and blindness?

Cheng Kai: if children with high myopia do strenuous exercise, such as playing basketball or boxing, they are easily affected by external forces, resulting in retinal detachment.

why do general doctors recommend that you use laser treatment after the age of 18?

Cheng Kai: laser surgery is actually corneal ablation. After myopia, if we cut the cornea, we can remove 0.1, almost 300 degrees. If the eyeball reaches a mature stage, we can do it, but if we do surgery in the growth stage, there may be some unforeseen problems, So I don’t have this operation until I’m 18. Does

and

suggest that we use laser to treat myopia?

Cheng Kai: personally, I don’t want you to adopt this method, because this method will bring many complications, and it has a great relationship with the level of doctors and the accuracy of instruments, and it can’t fundamentally solve the problem of myopia.

the pathogenesis of myopia is a process of ciliary muscle mediation. At the same time, it also shows the problem of light sensitivity of your retina. Can your optic nerve cells reflect quickly and sensitively? Myopia in many people is mixed, and there are many reasons, not only the performance of ciliary muscle, but also the problem of retina. If it is the problem of ciliary muscle, we need to find some ways to solve it.

what are the most common treatment methods for myopia?

Cheng Kai: in the field of modern medical treatment, it can be said that the treatment of myopia basically considers the treatment from his cornea and tries to make the cornea thinner. There used to be an OK lens, that is, a special recessive lens. These treatments were aimed at the cornea.

it is not laser therapy, but artificial compression. If you don’t press, your eyesight will go back. These two methods are long-term treatment methods that are not specially recommended by the medical community, which may be different from our traditional Chinese medicine theory. Our traditional Chinese medicine stresses treating diseases and seeking the root cause. Now many treatment methods may only treat symptoms, but the process of producing degrees needs a normal guidance and change of concept. The treatment method is the second. The key is the parents’ understanding of medical knowledge and the construction of normal physiological environment and optical environment for their children.

what good method does traditional Chinese medicine have to treat myopia?

and

Cheng Kai: Traditional Chinese medicine believes that there are many meridians in the human body. These meridians are actually the carrier of human function and information. Many meridians go into the eyes. Massage is only a stimulating method. We can treat them through eye acupoints around the eyes and some acupoints at the far end. There is a saying that “the meridians pass by, and the indications reach”. Therefore, we need to carry out physical treatment on these acupoints to improve some blood supply around the eyes.

physical therapy, such as massage therapy, puncture therapy and so on. The skin needle has a needle tip, but does not penetrate the skin, which can reduce the pain.

and

as the treatment of myopia, this is not the single method work of doctors. Any disease is mainly composed of personal reasons, especially in the process of myopia treatment. It emphasizes that doctors, children and their parents interact. Doctors solve medical problems, parents create children’s optical environment, and children should actively cooperate. In this way, after the tripartite interaction, myopia can be completely controlled or even treated, but to completely cure it depends on the degree of myopia.

and

what kind of children are prone to myopia?

Cheng Kai: children with unbalanced nutrition may form myopia, such as picky eaters, partial eaters, and children who don’t like vitamins. Unbalanced nutrition can also easily lead to obesity. Obese children have a higher incidence of myopia. Premature infants and newborn hypoxic infants may be more prone to this disease than other children. The day after tomorrow, children who lack exercise are also prone to myopia. Their physique is weak compared with other children, and they will also have myopia.

what are the usual eye care methods?

and

Cheng Kai: the easiest way is to ensure that you have a certain time to look into the distance, and you can relax and exercise the muscles around your eyes by turning your eyes. However, parents must supervise and urge your children to know and follow your methods.

how to treat pseudomyopia?

Cheng Kai: if it is pseudomyopia, it is also very easy to treat. You can recover through self-care or rest your eyes by mydriasis. Then it may be normal after a period of time. Through the method of self rest and relaxation, combined with certain treatment, it can be recovered.
