What is the genetic probability of myopia?

Both parties are pregenital, myopia is bound to be inherited.

If you have a problem, you may want to ask your ophthalmologist again. This is difficult to explain, to see the premise of the day after tomorrow, if you send your child to Tunzi, maybe the child is not myopia, of course, joking pull, say the theme, the child is not myopic to see 4-15 years old, this spring and autumn period of the child autumn water is easy to be in danger, first of all, as usual, to supervise the child, the computer plus the precautionary protection sticker, TV let the child watch less, to have good habits in further study, but, your child will be short-sighted, TV, computer radiation is now more, there will be more in the future, What we can do is to make the child's eyes myopic and not have a decrease in eye power! As far as I know, myopia is usually not inherited to the next generation, but one article reported that if both parents are myopia, the probability of inheriting it to the next generation is 25%.

The omentum macular area is the area with the clearest visual threshold, the macula is named because it contains a large amount of lutein, lutein is a strong antioxidant that can accommodate or enhance the antioxidant capacity of the omentum, and can also receive ultraviolet light and blue band color light that is more dangerous for autumn water, when you are not lutein enough, it can not effectively prevent the shielding effect of light on the macular area, and the macular area in order to avoid the damage of light to its self-shield, adjust the cornea to make its refractive transformation, So that the light does not fall on the macular area and falls on other parts of the omentum, so that the eyesight is not clear, and myopia occurs.

It is well established that myopia has a certain genetic predisposition, especially for high myopia. Studies suggest that two-parent families with high myopia have a higher incidence of myopia in the next generation. However, the genetic predisposition to myopia in general is not obvious.

The development of a person's internal organs and various organs is unbalanced, which is mainly determined by genetics, and if both of them have bad eyes, the possibility of inheritance to the next generation is very high.

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!

You can go to a regular hospital and do a genetic test, don't make a blind judgment.

If two people have a lot of feelings, then it's not worth ruining the relationship because of this problem.

Myopia, which can usually be passed on to the next generation, is mostly high myopia, that is, myopia of more than 600 degrees. If both parents have high myopia, the chance of passing on myopia to their children is about 90% or more.

If one of the parents is a patient with high myopia, the chance of passing it on to the child is about 50% or more, and high myopia is an autosomal recessive genetic disease. In addition, whether a person is myopic or not, in addition to the genetics from parents, is more affected by environmental factors.

Therefore, if parents have children with high myopia, they should pay attention to developing good eye habits from an early age, pay attention to resting their eyes, combine work and rest, usually do more outdoor sports, and have regular check-ups to avoid high myopia. Hereditary myopia is congenital myopia, if the child is born with myopia, usually the degree of this myopia will be relatively large, and the vast majority of patients will exceed 600 degrees, reaching the degree of high myopia. In addition to having a certain impact on the patient's daily life, high myopia will also increase the probability of fundus lesions, such as macular hole or posterior retinal detachment and other diseases, it is recommended that if the patient has high myopia, he should avoid strenuous exercise and have regular fundus examinations 1 or 2 times a year to prevent serious fundus diseases.

The probability of myopia inheritance mainly depends on the condition of the parents' myopia, not all myopia will be inherited, only parents who carry the high myopia gene will inherit. The inheritance of high myopia is basically an autosomal recessive inheritance, if both parents are highly myopic, their children are highly myopic; One of the parents is highly myopic, and the child suffers from high myopia; Neither parent has high myopia, and their children suffer from high myopia.

Myopia can be corrected by optics**, wearing eyeglasses to correct astigmatism, contact lenses, or by surgery**, such as excimer laser keratomectomy and intraocular lens implantation. The condition of different people varies greatly, and whether surgery is needed or not must be fully communicated with the attending doctor to understand the possible risks of surgery and make a decision after consideration.

To prevent myopia, we should use our eyes scientifically, reduce the time we spend looking at electronic products, and do more eye exercises. Participate in appropriate physical exercise to enhance physical fitness, and eat a nutritious and balanced diet.

If both parents have high myopia, the probability of myopia inherited to the child is about 90%, if one of the parents is highly myopia, the probability of inheritance to the child is about 50% or more, and high myopia is a chromosomal recessive genetic disease.

Many people believe that myopia is hereditary, so is myopia really hereditary? Let's find out. There are also many causes of myopia, and we need to understand the causes before targeting.

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.

The chance of myopia being inherited depends on the parents. If both parents are highly myopic, the next generation is more likely to develop myopia; If one parent is highly myopic and the other parent is a carrier of the gene, the probability of inheritance is also high; If both parents are carriers of the disease-causing gene, they themselves will develop myopia, even though they are not nearsighted. Their disease-causing genes are lost.

If a child has two myopia genes, the chances of developing myopia are higher.

The genetic chance of myopia is very small, both parents are highly myopic, and the risk of myopia in children is relatively high. Data survey: Parents are 5-6 times more likely to develop myopia than children whose parents are not myopia. Parents' myopia does not mean that the child is necessarily myopia, and conversely, if the parents are not myopia, it does not mean that the child is not myopia.

If myopia is caused by acquired factors, the chance of inheritance is very small. I know an old man who was born with myopia of 1200 degrees, and several of his children are not inherited, but his granddaughter was born with myopia of 800 degrees, and then ** recovered to more than 300.

Is there a good chance of myopia? This is generally highly myopia, and their genetic probability is still relatively large, so it is still necessary to protect their eyesight.

Myopia is not necessarily hereditary, if there is a certain genetic tendency to high myopia, that is, myopia higher than 600 degrees, there is a certain genetic chance, and other myopia below 600 degrees, the genetic probability is very small.

The genetic memory of myopia is still relatively small, unless both parents are highly myopic, so that the probability of inheritance is high.

Myopia is hereditary, especially high myopia. General high myopia refers to myopia above 600 degrees. There are two kinds of myopia, one is ordinary myopia, myopia is corrected with glasses, and it will stay at the original degree of myopia and will not deepen.

The other is high myopia, which increases in depth with age and is difficult to correct. It is very unfortunate that, according to statistics, the yellow race is the most likely to be myopic, the white race is moderate, and the black race is almost not very myopic. It can be seen that myopia is genetically inherited.

Generally, both parents in the family are myopic, and the child's inheritance is 100%; If one party is, it is 50%; Neither is the case, then 25%.

The scientific community has not yet reached a conclusion on the hereditary probability of myopia (physiological myopia), but it is definitely hereditary. And there are many children who have no genetics but only have myopia genes.

There are two major reasons for the onset of myopia: 1. Genetic factors. 2. The result of long-term overuse of eyes.

Myopia is a genetic disease with polygenic factors, and if both parents are highly myopic, the rate of myopia in children will be greater than 90%. So after knowing the reasons: 1. Pay attention to eye hygiene, such as looking less at these mobile phones, computers and other electronic products, and don't read books for too long, such as reading for 40-50 minutes and resting for a while, looking into the distance, you can relieve eye fatigue.

2. The light for myopia to see things should be appropriate, and the height of tables and chairs should be appropriate, and don't look at mobile phones or books when lying down or walking. 3. Regularly give the child a vision examination, once his vision is found to be abnormal, do dilated refraction to see if there is myopia, farsightedness, astigmatism. If there is, put on the eyes in time and have regular check-ups.

Myopia one. Are the odds high? Odds, right? Seldom. Cinnabar. Won't write. The guests were all short-sighted. Look at your phone.

Pathological myopia refers to myopia greater than or equal to 600 degrees, accompanied by axial lengthening, fundus degeneration and visual dysfunction, which seriously affects visual function. The general view is that high myopia has a high probability of heritability, and environmental factors and eye habits play a role, but genetic inheritance accounts for a larger proportion. Some may be carriers of myopia genes, which are autosomal recessive, and the genes are not explicit, so myopia does not occur.

There are also many parents who are not myopic and are not gene carriers, but their children are myopic and have a very high degree, but fortunately, this part only accounts for a very small number of myopia. There are also many people who have not been myopic when they were children, only in a certain period of time (such as college entrance examination, entrepreneurship, etc.), due to excessive pressure and excessive use of their eyes, which is basically caused by the environment. Therefore, about 65% of myopia is determined by congenital genetics, and 35% is determined by acquired environment.

However, carriers of myopia genes are more likely to suffer from myopia than ordinary people.

It's not big, and now there's technology**.

At present, it has been found from many studies that myopia is indeed related to genetics, but the onset of myopia is greatly affected by environmental factors. That is, myopia is determined both by the genetic traits of the parents and by environmental factors.

Many people think that myopia is hereditary, so is myopia really hereditary? Let's find out. There are also many causes of myopia, and everyone must know the causes before systematic treatment.

First of all, poor lifestyle habits and incorrect employment are all key factors that contribute to myopia. In everyone's living habits, there are many people who will gradually become myopic in their work and study, especially students, because of long-term staring at exercise books or exam papers, there is no correct sitting posture in the process of doing homework, and their eyes are too close to objects, and they look at things for a long time, which leads to myopia.

Secondly, because students stare at the classroom blackboard outside the window for a long time, when people's vision is blurred for a short time, the macula under the eyes will gradually adjust the focus, which is very easy to cause myopia in the long run.

The cause of myopia is not only caused by the understanding link, some people will also increase the probability of myopia because of long-term staring at the computer and mobile phone at work. Most of the occurrence of myopia is between the ages of 14 and 20, and the vast majority of them are not easy to improve the degree of myopia after the age of 20.

Myopia does have a hereditary probability, but the heredity of myopia is also interfered with by various factors, and there is no direct evidence in medicine at this stage that myopia is caused by heredity. However, in fact, parents with myopia will increase the risk of myopia in the next generation.

In general, people with relatively high myopia have a relatively high chance of passing it on to their offspring, mainly because there are underlying genetic diseases in the sex chromosomes of the body. If one of the parents has a relatively high degree of myopia, it will increase the chance of myopia in the next generation. About a small percentage of people in our population will have carriers of the myopia gene.

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

People with myopia must understand how to distinguish between occult myopia and pathological myopia, so that they can be accurately treated and corrected. Occult myopia can be improved through later training, as long as you don't have to be overly tired of work and study and training, as much as possible to prevent some incorrect sitting posture, moderately look into the distance, often do exercises around the eyes, reduce the fatigue around the eyes, and it will be gradually improved.

Pathological myopia is more serious, and such myopia groups generally have to go to the hospital for outpatient surgery, and some people must also wear corrective glasses, orthokeratology lenses, and vision correction to repair the conventional eye vision.

Myopia is a widespread eye disease that has long since become a common condition. In order to better prevent myopia, we should pay attention to eye hygiene in daily life, cultivate good eye fatigue habits, maintain a correct sitting posture, pay attention to reasonable arrangement of time, and appropriate eye fatigue.
