Abstract: myopia has a certain genetic tendency, which has been recognized, especially for high myopia. It is a common cause of myopia. But for general myopia, this tendency is not very obvious. Those with genetic factors had earlier onset age, mostly above 6.00D., In real life, some people suffer from myopia at a very young age, and many of them suffer from high myopia, which shows that the causes of myopia are likely to be related to the patients themselves and need special attention. What are the common causes of myopia? Let’s talk about the common causes of myopia., Generally, the common causes of myopia are: (1) genetic quality: myopia has a certain genetic tendency, which has been recognized, especially for high myopia, which is a common cause of myopia. But for general myopia, this tendency is not very obvious. Those with genetic factors had earlier onset age, mostly above 6.00D. But there are also high myopia without family history. High myopia belongs to autosomal recessive inheritance, and general myopia belongs to multifactorial genetic disease., (2) developmental factors: infants are hyperopia because their eyeballs are small, but with the increase of age, the ocular axis also gradually lengthens, and their development is normal until puberty. If overgrowth, myopia will be formed. This kind of myopia is called simple myopia, which mostly starts in school age. Generally lower than 6.00D. Development stops around the age of 20. If it progresses quickly in childhood, it will progress faster at the age of 15 ~ 20, and then slow down. This kind of myopia is often higher than 6.00D, and can reach 20d ~ 25d or 30d. This kind of myopia is called high myopia or progressive myopia or pathological myopia. Such myopia can occur and degenerate in old age, so vision can gradually decline, and vision can not be corrected with glasses. Very few have myopia at birth, but very few are congenital. This is also a common cause of myopia., The above is about the common causes of myopia. I hope it will be helpful to you. These causes of myopia are relatively common. Once you suffer from myopia, you must go to the hospital in time for active treatment to avoid the continuous deterioration of your condition.,
in real life, some people suffer from myopia at a very young age, and many of them suffer from high myopia, which shows that the causes of myopia are likely to be related to the patients themselves and need special attention. What are the common causes of myopia? Let’s talk about the common causes of myopia.
and
are common causes of myopia:
and
(1) genetic quality: myopia has a certain genetic tendency, which has been recognized, especially for high myopia, which is a common cause of myopia. But for general myopia, this tendency is not very obvious. Those with genetic factors had earlier onset age, mostly above 6.00D. But there are also high myopia without family history. High myopia belongs to autosomal recessive inheritance, and general myopia belongs to multifactorial genetic disease.
and
(2) developmental factors: infants have hyperopia because of their small eyeballs, but with the increase of age, the ocular axis also gradually lengthens and develops normally until puberty. If overgrowth, myopia will be formed. This kind of myopia is called simple myopia, which mostly starts in school age. Generally lower than 6.00D. Development stops around the age of 20. If it progresses quickly in childhood, it will progress faster at the age of 15 ~ 20, and then slow down. This kind of myopia is often higher than 6.00D, and can reach 20d ~ 25d or 30d. This kind of myopia is called high myopia or progressive myopia or pathological myopia. Such myopia can occur and degenerate in old age, so vision can gradually decline, and vision can not be corrected with glasses. Very few have myopia at birth, but very few are congenital. This is also a common cause of myopia.
the above is the explanation of the common causes of myopia. I hope it will be helpful to you. These causes of myopia are relatively common. Once suffering from myopia, we must go to the hospital in time for active treatment to avoid the continuous deterioration of the condition.
