How to distinguish pseudomyopia in three-year-old children

Abstract: what is the distinguishing method of pseudomyopia in three-year-old children? Myopia is divided into true myopia and false myopia. Pseudomyopia is a functional change. It has no organic changes. As long as we try to alleviate and regulate the spasm, pseudomyopia does not exist. Please refer to the following introduction for details., Children’s eyeballs are in the period of growth and development. If you don’t pay attention to eye hygiene, Make the anterior posterior diameter (i.e. eye axis) of the eyeball longer (more than 24 mm), so that after the parallel light enters the eyeball, the focus falls in front of the retina and can not form a clear image, which is myopia. Pseudomyopia refers to that the size and length of the eyeball have not changed, and the ciliary muscle is in a state of continuous contraction due to no attention to eye hygiene and excessive adjustment (i.e. regulating spasm), the lens continues to bulge and cannot recover, so the refractive power is greatly enhanced, so that after the parallel light enters the eye, the focus also falls in front of the retina, and the distant object can not be seen clearly. Therefore, pseudomyopia belongs to functional change. It has no organic change. As long as we try to alleviate and regulate spasm, pseudomyopia will not exist. Pseudomyopia is near Visual acuity is relative to true myopia. True myopia is that the refractive system of emmetropia is at rest, that is, after the adjustment is removed, the far point of the eye is located within a limited distance. In other words, myopia is caused by congenital or acquired factors, the anterior and posterior diameter of the eyeball becomes longer, and the parallel light forms a focus in front of the retina after entering the eye, resulting in blurred vision ‘. Pseudomyopia in three-year-old children can distinguish true and false myopia,

Children are in the period of growth and development. If you don’t pay attention to eye hygiene, Make the anterior posterior diameter (i.e. eye axis) of the eyeball longer (more than 24 mm), so that after the parallel light enters the eyeball, the focus falls in front of the retina and can not form a clear image, which is myopia.

Therefore, pseudomyopia is a functional change.

3-Year-old children with pseudomyopia distinguish true and false myopia

1 Cloud and fog method: first let the patient wear a convex lens with high degree, preferably 300 degree presbyopic glasses, so that the patient can’t see clearly, especially in the cloud for 20 ~ 30 minutes, in order to relieve the tension of ciliary muscle.

2. Mydriasis method: use ciliary muscle anesthetic, such as 1% atropine or 2% houmatopine solution, to anesthetize the ciliary muscle and remove the tension. Before the test with the above method, the far vision and optometry should be checked first. If the child’s vision has improved or returned to normal compared with that before the test, for example, the binocular vision is 0.5 before the test and 1.0 after the test, it can be diagnosed as pseudomyopia. Or optometry found that myopia significantly reduced or disappeared.

How did children get pseudomyopia? In addition to paying attention to and developing good eye hygiene habits, it is mainly to relax and adjust to achieve the purpose of treating false and preventing true.

The common methods of pseudomyopia in three-year-old children are Relax and adjust.

1. Mydriasis therapy: eyedrops with ciliary muscle paralysis, mainly atropine eye drops, once a day.

2、 Cloud and mist method: wear a convex lens of + 2.00 + 3.00 (i.e. presbyopic glasses of 200 degrees to 300 degrees) once a day. Each time, wear glasses to look at the distance for 15 ~ 30 minutes. 10 consecutive times are a course of treatment, and several courses of treatment can be repeated.

3. Overlooking method: after studying or writing for 1 hour, overlooking the natural scenery to relax the ciliary muscles. Overlooking method: after using your eyes for a period of time, try to look at the distance and look at the green trees better. Twice a day for 15 minutes.

4. Insist on doing eye exercises: do eye exercises 3 ~ 4 times a day, and do eye exercises once a day after using your eyes for a period of time, so as to make your eyes fully rest, relax and adjust, and eliminate eye fatigue.

Improve the learning environment: when reading and writing, pay attention to maintaining a distance of 30cm and correct posture. Pay attention to natural light and ensure adequate indoor lighting. Combine work and rest, get rid of bad learning habits, rest for 10 ~ 15 minutes every hour of reading, and don’t lie down or walk to read. Pay attention to strengthening physical exercise.

Because pseudomyopia aggravates with the extension of near sight time and the increase of accommodation, and reduces or disappears with the degree of far sight and relaxation, pseudomyopia has the characteristics of elimination when treated and recurrence when not treated. Taking a variety of methods may have a certain effect, but they can’t last long. Therefore, educating young children to form the habit of protecting their eyesight from childhood and avoiding excessive and continuous tension of ciliary muscle regulation is the key to prevent myopia.
