Abstract: in addition to “distinguishing true from false”, myopia can also be roughly divided into “pathological myopia” and “simple myopia”. Simplicity is common, with high incidence, easy correction and less complications. Compared with simple myopia, pathological myopia has a low incidence, but it is difficult to correct and has many complications., We all know the importance of eyes to a person. Without eyes, people will lose their light. Myopia is a common ophthalmic disease in our daily life. Many people feel that they already know enough about myopia, and myopia doesn’t seem so terrible compared with glaucoma, cataract and other diseases. But is this really the case? Next, let’s walk into myopia and see what myopia is all about., True myopia or false myopia. The main characteristics of myopia are long axial side and prominent cornea, which leads to blurred imaging of distant objects. The eyeballs of minors are relatively young. If they pay little attention, they may be short-sighted. But it is precisely because the child’s eye development at this stage is not mature, so timely correction is possible to restore vision. This condition is called “pseudomyopia”., Generally speaking, when matching glasses for myopia children, doctors will first distinguish whether it is pseudomyopia or true myopia. If it is pseudomyopia, they can make corresponding treatment in time without wearing glasses at all. However, if you wear glasses directly without determining whether it is true or false myopia, the following hazards will occur: 1 If the child is pseudomyopia, he / she will directly wear glasses without being checked out, and may gradually develop into true myopia., 2. There are many eye diseases that can cause vision loss, so we must find out the causes of vision loss, so as to effectively protect our eyes., 3. Children who have not undergone strict medical optometry may have amblyopia or aggravated astigmatism after glasses.,
we all know the importance of eyes to a person. Without eyes, people will lose their light. Myopia is a common ophthalmic disease in our daily life. Many people feel that they already know enough about myopia, and myopia doesn’t seem so terrible compared with glaucoma, cataract and other diseases. But is this really the case? Next, let’s go into myopia and see what myopia is all about.
true myopia or pseudomyopia
myopia is mainly characterized by long axial side and prominent cornea, resulting in blurred imaging of distant objects. The eyeballs of minors are relatively young. If they pay little attention, they may be short-sighted. But it is precisely because the child’s eye development at this stage is not mature, so timely correction is possible to restore vision. This situation is called “pseudomyopia”.
generally speaking, when matching glasses for children with myopia, doctors will first distinguish whether it is pseudomyopia or true myopia. If it is pseudomyopia, they can make corresponding treatment in time without wearing glasses at all. However, if you wear glasses directly without judging whether it is true or false myopia, the following hazards will occur:
1 If the child is pseudomyopia and doesn’t check it out, he can get glasses directly, which may gradually develop into true myopia.
2. There are many eye diseases that can cause vision loss, so we must find out the causes of vision loss, so as to effectively protect the eyes.
3. Children do not undergo strict medical optometry. After matching glasses, they may have amblyopia or aggravate astigmatism.
simple myopia or pathological myopia
myopia can be divided into “pathological myopia” and “simple myopia”. Simplicity is common, with high incidence, easy correction and less complications. Compared with simple myopia, pathological myopia has a low incidence, but it is difficult to correct and has many complications.
pathological myopia, also known as degenerative myopia, is an eye disease characterized by progressive deepening of diopter, continuous growth of eye axis, and visual dysfunction caused by progressive damage to eye content and retinal choroid tissue. The incidence in China is about 1% ~ 2%. It occurs early. Children can occur between the ages of 5 and 10, and progress rapidly. It will continue to develop after the age of 25. The degree of myopia can reach more than -15.00d, often accompanied by fundus changes, and vision is not easy to correct. According to incomplete statistics, about 10 ~ 20 million people in China are deeply troubled by pathological myopia, and their quality of life is seriously affected.
simple myopia and pathological myopia belong to the category of myopia, but their pathogenesis and harm are far from each other. The blindness rate of pathological myopia is much higher than that of simple myopia. Therefore, overcoming pathological myopia has always been an important topic in the field of Ophthalmology and optometry.
