Will myopia be inherited after treatment?

Myopia and genetic relationship:

Genetic factors play an important role in the occurrence and progression of myopia. Some people have done a large number of family statistics, also known as family surveys, where both parents have myopia, the percentage of their children with myopia is significantly higher than that of other families. If one parent has myopia, the myopia rate of children is in the middle.

Children whose parents do not have myopia have the lowest incidence rate. In addition, the incidence of myopia in yellow people is the highest in the world, and the incidence of myopia in Southeast Asia, including China, is more than 40%, and the white race is medium, while the black and Eskimo people have very little myopia, which shows the genetic role of the species. Chinese experts have conducted twin surveys, twins suffer from myopia at the same time or do not suffer from myopia at the same time, that is, the consistency rate, the results show that the twin agreement rate (myopia) is higher than that of non-twins.

Among twins, the myopia concordance rate of identical twins is higher than that of fraternal twins, which also indicates that myopia is a hereditary disease. Experts have also calculated that genetic factors account for 65% of the causes of myopia through formulas.

On the other hand, myopia is not completely determined by heredity, parents have myopia and not all children have myopia, and those with myopia genetic factors do not manifest or are not explicit, and myopia does not develop at this time. There are some congenital myopia, and they tend to have a higher degree, but fortunately only a very small number of myopia eyes. This type of myopia has a family history and is genetically determined.

Strabismus**:

1. Imperfect development: the monovision function of both eyes is not perfectly developed, and the extraocular muscles cannot be well coordinated, and external unstable factors (fever, fright, etc.) can promote the occurrence of strabismus.

2. Congenital anomalies: abnormal position of extraocular muscles, which can also cause punctate hemorrhage in the brain during childbirth, paralyzing extraocular muscles.

3. Characteristics of eye development: children's eyeballs are small, the eye axis is short, and most of them are farsighted. In addition, due to the strong contractility of the ciliary muscle of the corneal lens in children, the adjustment force needs to be more inward, and excessive radiation beating can easily lead to invertosis.

Is there a genetic relationship between strabismus?

Is there a genetic relationship between strabismus? This is a concern for all strabismus patients or parents. The conclusion drawn from clinical observation and applied twin genetic studies is yes – strabismus is hereditary.

As early as 1952, it was reported abroad that 158 cases of strabismus had a positive family history). In recent years, domestic and foreign scholars have used the twin method to study the results of the heritability of common exotropia are more than 70%, and the heritability of common exotropia has been reported in China. A group of strabismus families reported that 8 people in 4 generations suffered from the same extraocular myopathy, called congenital extraocular generalized fibrosis syndrome, and there were patients in each generation, which was chromosomally dominant.

Children with this disease marry normal people, and their offspring do not suffer from this disease. The clinical manifestations are that the upper eyelids cannot be raised, and the eyes need to be looked up, and the eyeballs are fixed in a certain position and cannot be rotated in any direction. It can be seen that strabismus has a certain hereditary nature, but not all strabismus is inherited.

It is now agreed that common strabismus has a multifactorial inherited characteristic.

Since it's already **. Probably not.

Myopia is hereditary, but whether a parent's myopia will be inherited depends mainly on the severity of myopia. If the degree of myopia of the parents is not very high, it will not be inherited in two or three. However, if the parents have myopia of more than six, the chance of inheritance is still relatively large.

First of all, bad lifestyle habits and incorrect employment are a major factor in myopia. In our living habits, there are many people who will slowly become myopic in work and study, especially students, due to staring at homework books or test papers for a long time, not having a correct sitting posture when writing homework, eyes are too close to objects, and seeing things for a long time leads to the occurrence of myopia.

Secondly, because students stare at the blackboard in the distance for a long time, when the person's vision is blurred for a short time, the retina will slowly adjust the focus, which is easy to cause myopia in the long run.

The cause of myopia is not only caused by the process of studying, some people will also increase the probability of myopia due to staring at the computer for a long time at work, and mobile phones. Most of the occurrence of myopia is between the ages of 14 and 20, and most of them are cases where the degree does not increase after the age of 20.

Myopia does have the possibility of heredity, but the heredity of myopia is also affected by a variety of factors, and there is no clear medical evidence that myopia is caused by heredity. However, parents who have myopia will increase the probability of myopia in their next generation.

Generally, people with high myopia have a relatively high probability of inheriting it to their offspring, mainly due to the existence of recessive genetic diseases in the human chromosomes. If one of the parents has high myopia, it increases the probability of myopia in the next generation. About a small percentage of our population has carriers of the myopia gene.

However, this does not mean that the next generation will have myopia, and most people are caused by irregular lifestyle habits.

There is a certain genetic possibility of myopia! And the higher the power, the higher the chance of heredity, so we must pay attention to vision protection.

General suggestions: 1. Pay attention to the time you use your eyes.

Children's eye development is not perfect, the ability to work is low, every time you read or write for an hour, you should let the child go to outdoor activities, do games, look into the distance, or observe the flowers and trees, so that the tense eye muscles are relaxed, eliminate fatigue. In addition, it is necessary to make the child's life regular, have enough sleep, and let the eyes get enough rest.

2. Pay attention to the light of your eyes.

Do not allow your child to read or write in dark light or sunlight. If a 25-watt light bulb is used indoors at night, the distance between the book and the bulb should be within 1 meter. If you use a 60-watt bulb on a stool, the distance between the book and the bulb should be 1 2 meters.

Cloudy days, dusk, weak light in the moonlight, and strong light in the sun are not suitable for reading and writing. When watching TV, it is necessary to maintain a suitable distance, which should generally be 5 7 times the diagonal length of the phosphor screen. The time to watch TV should not exceed 2 hours at a time.

3. Pay attention to eye exercise.

Physical exercise can enhance blood circulation and metabolism, supply more nutrients to the eyes, and enhance the resistance of the eyes, which is an indirect exercise for the eyes. The direct exercise is eye exercises, which are based on the scientific methods of massage, massage, acupuncture and moxibustion acupuncture points in Chinese medicine, combined with the protection of eyesight. Parents should learn the basic knowledge of eye exercises, give specific guidance and often urge their children to do eye exercises, and persevere.

4. Pay attention to eye nutrition.

In order to protect children's eyes, children can eat more carrots, animal liver, lean meat, to supplement vitamin A, or regularly supplement the comprehensive nutrition of the eyes with Leyan vision nutrients, and at the same time, it is also necessary to appropriately consume millet, tofu, animal liver and other supplements of vitamin B2, so as to avoid night blindness, corneal malacia, red eyes, dry itching and other symptoms. Eating too much sugar will harm your child's eyesight, so your child's sugar intake should be controlled.

5. Pay attention to regular inspections.

Regular check-ups are due to the fact that children's eye structure, binocular visual function, and intelligence are still in the process of continuous development after birth, and the content of the examination is different at different ages. The usual age of ophthalmologic examination is generally 2-7 days after birth, 42 days after birth, 3 months, 6 months, and 1 year of age, and then once a year. In this way, the problem can be detected early and corrected early, instead of waiting until the vision has deteriorated and there is a vision problem before going for a check-up.

Not all myopia is inherited. High myopia, pathological myopia, and familial myopia are easy to inherit. Both parents are myopic, or one parent is highly myopic, and it is easy to inherit it.

Statistically probability, there is about 25% of the probability of inheritance. In general, mild myopia is not inherited. The heritability of moderate myopia is very low.

Myopia can be prevented and controlled, and myopia prevention and control should start from a young age and cooperate with the guidance of an ophthalmologist.

Myopia is hereditary, but the probability and probability of inheritance are uncertain. If both parents are mildly myopia, such as only more than 100 degrees of myopia, the probability of this myopia inheritance is relatively small; If both parents are highly myopia, it is exceeded.

Of course, myopia can also be inherited, especially some highly myopic eyes. But usually acquired myopia is not inherited.

Is myopia hereditary? Myopia is not hereditary, myopia is just a vision disease caused by eye fatigue, this disease is not hereditary, as long as the fetus develops normally, his vision is normal. It's not hereditary.

Myopia is not inherited, myopia is acquired, generally the writing distance is too close, looking at the mobile phone and looking at the computer too much will cause myopia.

There is a possibility of hereditary high myopia, which is myopia with a degree of more than 1,000 degrees.

If it is congenital myopia, it is contagious, but if it is acquired myopia, it is not contagious, and they are genetically inherited.

If both husband and wife are highly myopia, of course, there will be genetics in this case, so we should also take good care of our eyesight.

This depends on the degree of myopia, and generally speaking, if you have high myopia, the chance of inheritance will increase.

Let's start with the types of myopia. Myopia can be divided into two types, namely high myopia and common myopia. Common myopia, also known as simple myopia, can occur from childhood to after the age of 20, that is, it rarely progresses, and the degree of myopia is generally below 600 degrees.

High myopia, also known as progressive myopia, is another eye disease completely different from simple myopia, with the increase of age, the anterior and posterior axis of the eye continues to lengthen, the back of the eye expands, accompanied by degenerative changes in the veinal retina of the fundus, and the vision is difficult to correct to normal after wearing glasses, and the vision gradually decreases, so that serious disorders occur.

According to the results of the investigation of eye diseases, the incidence of myopia in family members with a family history of myopia is higher than that of those without a family history of myopia, indicating that the incidence of myopia is related to heredity. However, the occurrence of myopia is affected by acquired environmental factors, so at present, scholars believe that myopia belongs to polygenic inheritance, that is, patients have multiple pathogenic genes, but they are affected by environmental factors, which is a phenomenon that is easy to see in the occurrence of simple myopia. Environmental factors include poor lighting, poor reading and work habits, such as long hours of reading and close work, and a constant state of tension and contraction of the regulatory muscles of the eye, which in turn weakens the ability to accommodate, resulting in myopia.

But under the same conditions, not all people develop myopia, and some people with myopia do not do close work or rarely read books and newspapers. It can be seen that myopia is the result of a combination of genetics and environment.

For high myopia, it is thought to be caused by autosomal recessive inheritance. That is, both parents are highly myopic (note: this refers to high myopia!).

If one parent is highly myopic and the other is a gene carrier (no myopia), the expected incidence of high myopia in a child is 50; If neither partner has high myopia but is only a gene carrier, the incidence of high myopia in the child is 25.

Myopia, whether it is hereditary or not, will have a very serious impact on people's lives in the future, and now myopia is getting younger and younger, preventing myopia from an early age, myopia detection and treatment, has become the primary task of many families. Children under the age of 18, because they are in the period of vision development, the adjustment of the eyes is strong, and the child has myopia or signs, parents only need to give the child Leyan vision nutrients in time, twice a day, one pack each time, take it with warm water, and insist on taking it for a period of time. Those who are not myopic can prevent myopia, and children with myopia can reduce the degree of myopia and prevent myopia from being inherited to the next generation.

Nowadays, the inheritance of myopia covers almost all inheritance patterns, but most of the simple myopia is polygenic inheritance. That is to say, the environment plays a very important role in it, so simple myopia is also called "school myopia", which is mainly caused by environmental stress. Genetically related myopia is often high myopia, and there are some myopia with obvious complications and other complications, which are called genetically related myopia.

So far, population genetics studies have found that as long as one of the parents is myopic, the probability of a child developing myopia is twice higher than that of both parents who are not myopic. If both parents are nearsighted, it is higher than in a family where both parents are not myopia, up to a number of times. Surveys have been conducted in this group, such as in primary schools, and the prevalence of myopia in children at the age of 7 is 7.0% if both parents are not nearsighted.

However, as long as one party has myopia, it is as high as 26.0%.

For children, if one parent has a high degree of myopia, the child is more likely to develop myopia. Let's see if your child is prone to myopia!
