watch out! Anisometropia that affects your child’s development

Abstract: hyperopia may lead to strabismus. In order to obtain a clear image, patients with hyperopia need the adjustment of the ocular refractive system whether they look far or near. Excessive adjustment and accompanying internal transfer induce endophthalmos.

anisometropia affects children’s visual development, and it is necessary to correct the incidence rate of abnormal vision such as

,

myopia, hyperopia and strabismus. When it is found that the child’s two eyes have a large difference in vision, it should be treated in time to avoid affecting the development of the child’s visual function.

the difference between myopia and hyperopia

myopia is very common in life, but hyperopia is easy to be ignored. So, what is the difference between myopia and hyperopia? Myopia can’t see distant objects clearly. Distant objects are imaged in front of the retina and need to wear concave lens for adjustment; The hyperopia eye cannot see the near object clearly. The near object is imaged behind the retina and needs to be adjusted by wearing a convex lens.

and

hyperopia may cause strabismus. It is necessary to find and treat

and

hyperopia in time, which may lead to strabismus. In order to obtain a clear image, patients with hyperopia need the adjustment of the ocular refractive system whether they look far or near. Excessive adjustment and accompanying internal transfer induce endophthalmos. Esotropia not only affects the child’s vision, but also destroys the binocular monocular function and affects the appearance, which may cause the child to have inferiority complex.

anisometropia and its harm

anisometropia is called the unequal diopter of the two eyes, including myopia, hyperopia and astigmatism. For example, myopia in the left eye is 200 degrees and myopia in the right eye is 400 degrees. Anisometropia is mainly caused by the imbalance of ocular axis development. Anisometropia can cause visual fatigue, unequal images, loss of stereo vision, amblyopia and strabismus.

mild anisometropia generally does not cause discomfort. When moderate or high anisometropia is reached, the size of binocular visual object images is different, resulting in fusion difficulties, resulting in adjustment contradictions between binocular eyes, resulting in vision loss, monocular amblyopia, monocular exotropia, etc. For the treatment of anisometropia, the common methods are wearing frame glasses, high oxygen permeable corneal shaping glasses or laser surgery. The advantage of

and

frame glasses is that they are easy to wear, but for patients with anisometropia, the correction effect is poor and there will be discomfort such as vertigo. The advantages of corneal plastic lens are good correction effect, wide field of vision and good visual quality, but special attention should be paid to the cleaning and disinfection of the lens.

mixed anisometropia, one eye myopia and one eye hyperopia

then, will there be one eye myopia and one eye hyperopia? Yes, this is mixed anisometropia. If the parallax is small, the right eye can be used for those who look close and the left eye can be used for those who look far. The “single vision” can be used. The brain can adjust automatically without discomfort. However, if the parallax is too large, dizziness and fatigue will occur. Generally, corneal shaping glasses can be worn for correction.

and

ophthalmologists remind: to maintain the correct pen holding posture, look at the near objects with both eyes at the same time, and don’t look askew, so as to avoid anisometropia in the eyes.

and

learn the piano too early. Children may be short-sighted. When the summer vacation comes, many parents will sign up for piano training classes for their children. But some people say that learning the piano too early will lead to children’s myopia. Is that true? Experts say that when children practice playing the piano every day, their fingers play the piano, but their eyes should look at the score for a long time. The notes on the score are small and dense. You need to constantly adjust the eye ciliary muscle to focus, which will lead to myopia.

preschool is the key period of eye development. Excessive eye use at this stage will have a great impact on children’s eyes. If you want children to learn piano, you should pay attention to the combination of work and rest, let children play outdoors more, and check their eyesight regularly.

junior high school is the peak period of myopia outbreak, and should focus on prevention. The survey of

shows that junior high school is the peak period of myopia outbreak, and 46.5% of people begin myopia from junior high school. From primary school to junior high school, academic pressure becomes heavier and eye use intensity is high, which are the reasons for children’s myopia. Therefore, if a child has just entered junior high school, parents should pay more attention to their visual changes and remind their children to pay attention to eye hygiene. Nearly 50% of parents of

and

lack awareness of myopia prevention and control. The data of

and

show that 45.4% of parents do not take the initiative to understand the relevant knowledge of myopia prevention and control after their children are myopia. Children do not have accurate expression ability and do not understand the harm of myopia. If parents do not take the initiative to understand relevant knowledge, it is unfavorable to the treatment of children’s myopia.

juvenile myopia deepens and will develop rapidly if not controlled. Once become a high myopia (above 600 degree), even if the operation is done after adult, the vision is improved, but the pathological basis of fundus disease is still in existence. The incidence rate of fundus disease is still far higher than that of the general population.

Parents should take their children to outdoor sports as much as possible, which can not only exercise, but also prevent myopia. Patients with anisometropia should also pay more attention to rest and alleviate visual fatigue.
