How many degrees of myopia can parents pass on to their children?

Abstract: high myopia has certain heredity, which has been recognized by everyone. Over the years, genetic studies have proved that the vast majority of high myopia is autosomal recessive. People with this kind of myopia are often very young, and the degree of myopia is very deep. Many people’s parents are also highly myopic.

according to incomplete statistics, among the 400 million myopic patients in China, the proportion of patients with high myopia has reached 35%, and still shows a gradual upward trend. More than 300000 people have been blinded by high myopia in China, and China has become a serious disaster area of high myopia.

high myopia and its harm

myopia degree exceeds 600 degrees or the length of ocular axis exceeds 26 mm, which is called high myopia. In addition to high diopter, high myopia is also accompanied by pathological changes of fundus, which is an important cause of blindness. In some patients with high myopia, the myopia diopter and axial length will continue to increase in their life, which not only affects their vision, but also prone to complications such as glaucoma, cataract, macular neovascularization, retinal splitting, retinal detachment and so on. If you have high myopia since childhood and do not have timely, correct and effective treatment, it is likely to lead to amblyopia, strabismus and so on.

high myopia heredity

high myopia has a certain heredity, which has been recognized by everyone. Over the years, genetic studies have proved that the vast majority of high myopia is autosomal recessive. People with this kind of myopia are often very young, and the degree of myopia is very deep. Many people’s parents are also highly myopic. Although high myopia has a certain relationship with heredity, it is not absolute. There are two main reasons for high myopia.

on the one hand, the degree of myopia increases year by year and develops into high myopia because ordinary myopia does not choose appropriate glasses or does not pay attention to eye hygiene. This kind of myopia is generally below -10.00d, without heredity, also known as acquired high myopia. Another reason for

and

is that parents have high myopia or have high myopia gene, and their children have high myopia gene or high myopia after birth. This myopia is closely related to heredity. There are four cases of the potential for

high myopia to be transmitted to the next generation: the

and

1 couples are all high myopia, and their children usually have a incidence rate of over 98%.

2 if one of the parents is highly myopic and the other is normal, 10% – 15% of their children are ill;

3 if one party is high myopia and the other party is myopia gene carrier, the incidence of high myopia in their children is about 50%;

4 if both parties are myopia gene carriers, but their eyesight is normal, the incidence of high myopia in their children is 25%.

is there a particularly good treatment for high myopia?

if parents find that their children squint and get used to looking at things, they should be particularly vigilant and take their children to ophthalmology examination regularly. If the child has myopia, try to avoid deepening the degree to prevent pathological changes in the fundus. Since most of the pathological changes of high myopia are synchronized with the development of diopter, it is very important to control the development of diopter, In recent years, it is highly recommended to wear corneal shaping glasses (which is different from the commonly used soft glasses. It is a hard contact lens to wear when sleeping at night). The most reliable way for children with

and

is to wear frame glasses. Even preschool children must check their glasses to avoid delaying the best treatment opportunity. If they are found to have amblyopia, they should be patient in amblyopia treatment.

Patients with

high myopia should take more outdoor activities to reduce the progression of myopia; At the same time, vigorous sports such as diving, boxing, weightlifting and bungee jumping, as well as antagonistic sports such as basketball and football should be avoided. In addition, regular eye examination and optometry should be carried out in regular eye hospitals, preferably once every six months (at least once a year), so as to find and treat its complications as soon as possible and avoid blindness.
