Can parents’ myopia be passed on to their children?

Abstract: there are two kinds of common myopia, one is simple myopia, the other is high myopia. Simple myopia, also known as ordinary myopia, refers to low and moderate myopia below 600 degrees. It is very common and generally physiological. At present, there is no obvious evidence that ordinary myopia can be inherited.

nowadays, 80 and 90 parents have more myopia, feel distressed and worry that their myopia will be passed on to their children. Will parents’ myopia be passed on to their children?

can parents’ myopia be passed on to their children?

and

data show that about 10% of myopia children aged 3-6 belong to genetic factors. In a further investigation of 100 children with a family history of genetic myopia, it was found that 67% of children had myopia before the age of 10.

and

can be seen from the medical record statistics of previous diagnosis and treatment: for children with myopia and astigmatism aged 5-10, one or both of their parents have eye diseases such as myopia, amblyopia and astigmatism.

therefore, excluding the causes of the acquired environment, children aged 3-6 years old have high myopia, which is closely related to heredity. It is an autosomal recessive disease, which is determined by a pair of genes located on the autosome.

is simply, Everyone has this pair (two) genes, which come from their parents. If a person has both genes, the baby will be very likely to have high myopia, and the degree of myopia will be similar to that of his parents in the future.

There are two kinds of common myopia, one is simple myopia, the other is high myopia. Simple myopia, also known as ordinary myopia, refers to low and moderate myopia below 600 degrees. It is very common and generally physiological. At present, there is no obvious evidence that ordinary myopia can be inherited. High myopia refers to myopia with high diopter, obvious extension of ocular axis and atrophy and degeneration of fundus. It is divided into pathological and physiological. Pathological high myopia is hereditary.

if both couples are highly myopic, their children usually get sick. If one side is very high myopia, the other side has normal vision, and the incidence rate of children is 10%-15%. If one party has high myopia and the other is a myopia gene carrier with normal phenotype, the incidence of high myopia in their children is 50%. If both parties are myopia gene carriers, but their eyesight is normal, the incidence of high myopia in their children is 25%.
