Classification and prevention of myopia

Abstract: the formation of pseudomyopia is due to the insufficient adjustment range of patients. Long-term close eye use leads to long-term visual fatigue. Fatigue cannot be sustained, which is bound to make the eyes enter a compensatory state and produce functional compensation such as ciliary muscle spasm. Classification of

myopia

pseudomyopia

pseudomyopia etiology: it is caused by ciliary muscle spasm used for a long time and close distance.

when the eyes look close, they must use adjustment to see clearly. The closer they look, the more adjustment they need. Long time close eye use leads to tension of adjustment or spasm of adjustment function. The eyes cannot relax the adjustment when looking at hyperopia, and the vision decreases.

early pseudomyopia can be treated properly, which can improve vision and completely eliminate the degree of myopia. Classification of

myopia

mixed myopia

mixed myopia etiology: it develops from pseudomyopia.

mixed myopia is also called intermediate myopia or semi true myopia. Patients with mixed myopia usually show myopia. After using ciliary muscle paralysis drugs or fog vision, the myopia diopter decreases, but the myopia can not be completely eliminated. The occurrence of mixed myopia of

and

has both regulatory factors and organic factors. The degree reduced after regulatory relaxation is the result of functional compensation, and the remaining degree that cannot be eliminated is the result of organic compensation.

attention!

mixed myopia can reduce the degree of wearing glasses. Through treatment, it can restore the part of regulating spasm. If it is not ignored, it will turn into true myopia. Classification of

myopia

true myopia

true myopia etiology: it develops from mixed myopia. Characteristics of

and

true myopia: ① the degree of myopia is mostly medium and high myopia, the development time is long, and the patient’s glasses have produced different degrees of organic lesions. ② True myopia will not self adjust and recover. If children’s myopia is not controlled, it will continue to deteriorate.

ophthalmologists remind: myopia patients with more than -6.00d will lead to autosomal recessive inheritance, and high myopia will bring a series of complications and seriously affect visual function.

attention! The development of true myopia can be controlled. The increase of degree and the occurrence of complications can be controlled through training.

prevention and treatment principle of myopia

treatment of false and true

the formation of false myopia is due to the insufficient adjustment range of patients. Long-term close eye use leads to long-term visual fatigue. Fatigue can not be released, which is bound to make the eyes enter the compensatory state and produce functional compensation such as ciliary muscle spasm.

and

are mainly used to treat early pseudomyopia through adjustment function training, atropine and prism.

visual training for pseudomyopia — training of adjustment function (adjustment amplitude and adjustment sensitivity)

It is the most effective way to cure pseudomyopia by regulating functional training. The vision rehabilitation instrument adopts pure physical green therapy to train the adjustment function of patients with pseudomyopia, which can eliminate myopia in the bud, so as to effectively avoid the occurrence of true myopia.

myopia prevention and treatment principle

true prevention and treatment

pseudomyopia is only a functional compensatory state, while patients with mixed myopia and true myopia have had different degrees of organic compensation.

and

although the diopter of mixed myopia is generally low, there are also some components of true myopia. Therefore, like true myopia, mixed myopia cannot completely eliminate the degree of myopia through training. The increase of diopter of

and

is the result of organic compensation in children with myopia, that is to say, there have been changes in eye structure such as corneal curvature and axial length in children with true myopia. The axial growth of true myopia is just like the height of a child. It will only grow longer and not shorter.
