I now know if it s true myopia or pseudomyopia. 5

It should be true, go with glasses, 300 degrees below do not need to be worn often, that is, wear when you are far away, the most important thing is to look at your usual protection, work at close range for a long time, be sure to let the eyes look far away for 10 minutes, pay attention to eye fatigue, it also needs to rest.

Pseudomyopia is caused by eye strain, which is caused by the spasm of the ciliary muscles due to overuse of the eyes, and vision can be restored after adequate rest.

True myopia is caused by an elongation of the eye axis or the refractive power of the eye's refractive system, which is related to genetic factors and poor eye habits.

The main method of judging pseudomyopia and true myopia is through hospital dilated refraction, and the principle of dilated refraction is mainly to numb the ciliary muscle with drugs to make the adjustment completely relaxed. Parents will worry that their child will have myopia, but it is not necessarily, because the ciliary muscle spasm is in a state of over-regulation when the eye is overused, which is manifested as a decrease in distance vision and normal near vision, which can be distinguished by optometry. If cycloplegic refraction may be found to be not necessarily myopic but farsighted, the younger the child is, the more prominent the above phenomenon becomes.

Therefore, to distinguish between true myopia and pseudomyopia, it is necessary to judge through dilated refraction, and auxiliary examinations can be carried out, such as corneal curvature and eye axis length, to help determine whether the axis length of the child's eye is consistent with the average value of normal age, and whether the curvature of the cornea is on average. Through the above aspects, it is possible to distinguish true or pseudomyopia.

Pseudomyopia is caused by frequent incorrect use of the eye, and the ciliary muscles continue to contract and spasm, and the lens is in a state of thickening. In this way, the parallel light from the outside enters the eye, and after the atrial refraction of the thickened lens, the focus falls in front of the retina, and it is naturally not clear to see things in the distance. During this period, there are no organic changes in the eyeball, and if you can take proper rest and **, pay attention to eye hygiene, and use the eyes reasonably, there is hope to restore normal vision.

However, if it is not corrected in time in the stage of pseudomyopia, it will develop into true myopia over time. **There are many methods of pseudomyopia, mainly relaxation and regulation, such as: the use of cycloplegic agents to dilate pupils, acupuncture, physiotherapy, improve the learning environment, pay attention to eye hygiene, and do eye exercises seriously.

The simplest thing is to do a dilated pupil, myopia is not terrible, what is terrible is to let it go and become highly myopia.

Most of the myopia is caused by improper use of the eyes so that the eyes are in a state of eye fatigue for a long time, such as watching the computer for a long time, be careful not to let the child use the eyes for a long time, watching TV and watching the computer or something is best not more than 30 minutes.

In addition, you can take a look at (Xiao Chengzi has clearly returned) that the fake can be recovered, don't delay!!

The vast majority of people with myopia are non-pathological, or the vast majority of myopia is not a disease, but a kind of vision dysfunction decline caused by poor eye use, and the fundamental cause of the change of near vision function is excessive near vision and lack of distance vision and exercise. It is recommended to look far away during the rest time to reduce visual fatigue. From a distance, you have to look at something five meters away, not up close.

Look at something a little blurry until you see it clearly. More than five minutes. It is recommended to use two cups of Pupil Kernel Tea a day to clear the liver and eyes, soothe meridians and activate the meridians, and accelerate the metabolism of the eye capillaries.

It is necessary to determine whether it is true or pseudomyopia through normal refraction examination, scientific eye use in the later stage of pseudomyopia, pay attention to eye hygiene, and the eye environment can be recovered, if it is true myopia, it needs to be corrected by glasses or surgery.

If you go to a regular hospital for dilated eye refraction, you can know whether it is pseudomyopia. Whether it is true myopia or pseudomyopia, it is necessary to pay attention to healthy eyes and protect your eyes.

True myopia does not disappear during dilated refraction. Pseudomyopia is the loss of myopia after pupil dilation. Simple pseudomyopia is rare, and it is more likely to be accompanied by partial pseudomyopia in the early stage of myopia, that is, there is myopia in the natural vision, and the refraction power of dilated pupils is reduced, but myopia still exists.

Pseudomyopia is functional, caused by accommodative spasm, with a normal axial axis. It is more common in children and adolescents who are younger, have a shorter onset time, and have low diopters. Pseudomyopia should not wear myopia glasses, which can be restored to normal with rest and appropriateness**.

True myopia is organic, determined by the elongation of the eye axis, corneal curvature, etc., and has no obvious relationship with accommodation. It is more common in adolescents who are older, have a longer onset time, and have a higher refraction. True myopia should be treated with myopic glasses to correct distance vision.

I'm not a doctor, but I have graduated with a master's degree and have no myopia, and thanks to a bit of pseudomyopia in junior high school, my father kept me wearing +150 reading glasses to correct it. 1-2 hours a day, when you look at the writing, you will be a little dizzy, and it will be much better to get used to it.

For accurate examination, it is necessary to go to the hospital for a dilated pupil examination, so that there can be an accurate answer.

Definition of pseudomyopia: due to the spasm of the ciliary muscle caused by excessive eye viewing, there is still some adjustment that cannot be relaxed when looking at the distance, and mild hyperopia and emmetropia are manifested as myopia, and the degree of myopia is deepened.

These phenomena are collectively known as pseudomyopia.

Distinguish between true myopia and pseudomyopia.

Both true and pseudomyopia manifest as decreased distance vision and good near vision. Pseudomyopia is functional, more common in adolescents, and vision can be reduced within a few weeks or 1 or 2 months, and can be restored to some extent with appropriate rest. True nearsightedness is an organic change that cannot be recovered spontaneously.

There are three methods of differential diagnosis:

1) Ciliary muscle paralysis method: It is to relax and adjust the ciliary muscle with cycloplegic drugs, relax the ciliary muscle, make the eye in a static refractive state, and then check the visual acuity and refraction to determine. with 1% atropine eye drops, 1 2 times a day for 3 to 4 days; or 2% postmatropine or tropineamide every 5 to 15 minutes for a total of 6 times.

If the visual acuity remains unchanged after dilation, it is true myopia, and the visual acuity increases to pseudomyopia. Refraction with myopia is true, and no myopia is false. This is recognized as the most reliable method for differential diagnosis.

2) Cloud and fog method: let the patient wear + spherical lens with both eyes at the same time, see distant objects for 3 minutes, and then remove the right lens, and immediately check the naked eye vision. The left eye is then examined in the same way. This method is not very exact.

3) Dynamic imaging method: do not need to dilate pupils, first check the distance and near naked eye vision of both eyes. Poor distance visual acuity, normal near visual acuity, and no other eye diseases that affect visual acuity are differentiated. The doctor and the patient sit facing each other in the darkroom.

The patient wears an audition frame, and the left and right eyes are placed + spherical lenses. The patient's eyes are fixed on the optoscopic scope with both eyes at the same time (the No. 5 character or the word with few strokes such as large, small, upper and lower strokes is pasted on the side of the mirror, and illuminated with slit light next to the ophthalmoscope); 33cm distance isotope dynamic imaging.

Results: Those with reverse movements in all radial directions of the affected eye are true myopia. Each radial direction is forward or immobile, or one radial is forward and the other radial is orthopedic or farsighted.

Because of its manifestation of myopia, it is pseudomyopia; One radial direction is inverse, and the other radial direction is forward or immobile is mixed astigmatism.

I learned that these are two different eye diseases, both caused by not paying attention to the use of the eyes, unhygienic eye habits, and often wearing glasses.

If you understand the reasons and the differences, you will have different reactions, you will have different manifestations, and your eyes will change differently.

Pseudomyopia is functional myopia in which the axial length is normal, whereas true myopia is an organic lesion in which the axial length is usually longer. Pseudomyopia is the contraction of the annular ciliary muscle, the suspensory ligament of the crystal, the convexity of the lens due to its elasticity, and the increase in curvature enhances the refractive power and produces accommodative spasm; Pseudomyopia, such as blind glasses without accurate refraction or not, long-term ciliary muscle spasm, can also elongate the eye axis and develop into true myopia. Here's how to identify it:

1) Mydriatic method: pseudomyopia - after the use of atropine, the refractive power of myopia disappears, and it appears as emmetropia or hyperopia; True myopia - the degree by which the refractive power of myopia has not decreased or decreased after the use of atropine; 2) Cloud and fog method: let the patient wear a convex lens with a higher power and look at the eye chart 5 meters away, which can relax the ciliary muscle in a spasmodic state and eliminate the adjustment effect.

At first, the patient will feel blurred vision, after a few minutes, it will feel a little clearer, and then gradually reduce the power of the convex lens, if the visual acuity returns to normal or has a significant improvement compared with the pre-test visual acuity when decreasing to a flat lens without power, it proves that it is pseudomyopia.

The main difference between "pseudomyopia" and "true myopia" is whether there is an increase in the eye axis and whether vision can be restored. The main difference between true myopia and pseudomyopia is the change of the eye axis, myopia refers to the focus of the eye in a state of adjustment at rest, that is, the place behind the refractive system formed by the parallel light passing through the eye is before the retina, and the image formed on the retina is a blurry virtual image, and the vision is reduced. The cause of myopia is not yet clear, the diameter of the anterior and posterior eyeballs is long, the eyeballs are slightly protruding, pseudomyopia generally has no axial changes, it is caused by ciliary muscle spasm, and after dilated pupils**, vision can be restored.

Pseudomyopia is common in children. When there is an object in the near distance, due to the adjustment intensity and duration of the use is too long, the ciliary muscle continues to contract, resulting in tension adjustment or adjustment convulsions, so that after reading and writing from a distance, it can not be quickly adjusted and relaxed, dizziness causes visual fatigue, eyeballs, vision loss, etc., at this time, due to the enhancement of the refractive power of the eye, the eye is in a myopic state, which is called pseudomyopia.

Pseudomyopia refers to the fact that the ciliary muscle is in a state of tension during close operation, and excessive tension leads to spasm of the ciliary muscle, which continues to maintain the regulating effect of tension even when looking at distant objects, which is more common in young students, and after the use of atropine accessory muscle, pseudomyopia will temporarily disappear. True myopia refers to the fact that in the case of loose eyeballs, the refractive ability of the refractive system is relatively strong, and the parallel light is focused in front of the retina and diverges on the retina to form a blurred circle. Objects close to the eye are divergent and cannot be focused on the retina, and the near is clear and the far is blurry when examined, which is true myopia.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

With the increasing application of electronic products, some junior primary school students wear glasses on the rise. Parents have heard of true myopia and pseudomyopia, and when the child is less than 12 years old and comes to optometry for the first time, the doctor will recommend chronic atropine dilated eye refraction, which can distinguish between true and false. If it is found that the child's myopia is gone, and the prescription is between 0-50 degrees, it is an emmetic eye, which means that the child's myopia is pseudomyopia, which can be relieved by dilating eye drops, and glasses are not required.

If the prescription still exists after dilated refraction, and exceeds 50 degrees, it is true myopia, which cannot be relieved by itself and needs to be solved by optometry.

Below the following is considered true myopia. It belongs to pseudomyopia between and pseudomyopia, which is prone to squinting, blinking, rubbing, and blurring of squint eyes.

The easiest way is to dilate the pupil refraction, if the child's vision becomes better after the dilated pupil, it is pseudomyopia.

If you still can't see clearly after dilating your pupils, you need to wear a pair of glasses with a prescription to see clearly, which is true myopia.

If there is no prescription, it means that it is false myopia, and if there is a prescription, it means that it is true myopia, and dilated refraction can also be performed.
