Abstract: if the degree of myopia exceeds 600 degrees or the length of ocular axis exceeds 26 mm, it is called high myopia. In addition to high diopter, high myopia is accompanied by pathological changes of fundus, which is an important cause of blindness., According to statistics, among the 400 million myopic patients in China, the proportion of patients with high myopia has reached 35%, and it is still rising gradually. More than 300000 people have been blinded by high myopia in China, and China has become a serious disaster area for high myopia., High myopia and its harm. If the degree of myopia exceeds 600 degrees or the length of eye axis exceeds 26 mm, it 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 without timely, correct and effective treatment, it is likely to lead to amblyopia, strabismus, etc., High myopia is inherited. High myopia has a certain heritability, 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, because ordinary myopia does not choose appropriate glasses, or does not pay attention to eye hygiene, the degree of myopia increases year by year and develops into high myopia. This kind of myopia is generally below -10.00d, without heredity, also known as acquired high myopia., Another reason is that because both parents have high myopia or have high myopia gene, their children have high myopia gene or high myopia after birth. This myopia is closely related to heredity., According to 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. The probability of
high myopia to the next generation is as follows:
,
1, and both the husband and wife are all high myopia, whose children usually have an 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 children’s high myopia is 25%.
is there a particularly good treatment for high myopia?
if parents find that their children squint, get close to things, squint, etc., they should be especially vigilant and take their children to the eye 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 (different from the commonly used soft glasses, which are hard contact lenses worn at night) and multifocal progressive glasses.
If your child has developed high myopia, you can take femtosecond laser, excimer laser therapy, wear glasses or contact lenses. If it is monocular high myopia or the degree difference between the two eyes is greater than 200 degrees, it is more suitable to choose contact lenses. ICL implantation (intraocular lens implantation with lens) carried out in recent years has obvious therapeutic effect on those who cannot perform excimer laser surgery for very high myopia (higher than 1000 degrees). However, the above methods are only applicable to adults over the age of 18. The most reliable method for children is to wear frame glasses. Even preschool children must be fitted with glasses to avoid delaying the best time for treatment. If you find amblyopia, you should be patient to do amblyopia treatment.
high myopia patients 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 conducted in a regular eye hospital, preferably once every half a year (at least once a year), so as to find and treat its complications as soon as possible,
