Before the child s myopia refraction, is it good for the body to do rapid pupil dilation, thank you,

Beijing Mingshi Eye Hospital Zhou Yuehua Chief Physician Ophthalmology If the child is nearsighted, must he have dilated refraction?

It's okay, and it's best to see your examination is a dilated pupil test, because the difference in vision between the two eyes is relatively large, and there may be amblyopia, which has to be done as soon as possible**.

Dilated pupils do not affect to check whether it is congenital previously neglected.

Most of the vision loss in children at this age is pseudomyopia or mixed myopia (i.e., true and pseudomixed myopia), and the dilation of pupils is to rule out the pseudomyopia part and check for true myopia! If the visual acuity after pupil dilation reaches the national standard, glasses are not required; Otherwise, it should be treated with glasses! And at this time, parents are more anxious, easy to rush to the doctor, believe what instruments can cure myopia, in fact, most of these instruments are the same principle as doing eye exercises, are to relax the eyes to let the eyes recover, only effective for pseudomyopia!

Therefore, it is recommended that you go to a hospital or a professional optical store to find a trustworthy, professional doctor or optometrist for dilated eye refraction (intraocular pressure needs to be checked before dilation)!!

Summer vacation is the busiest time for the hospital's ophthalmology clinic. Professor Lan Yuqing, director of the Department of Ophthalmology at Sun Yat-sen Memorial Hospital of Sun Yat-sen University, reminded parents to take their children for vision examinations and establish visual archives every year from the age of 3.

Before checking your eyesight for the first time.

To "warm up" in this way

Lan Yuqing pointed out that most of the 3-year-old children in Liangpei were able to cooperate with the eye chart. As a "warm-up", parents can initially teach their children to identify the direction by placing the "e" word in different directions at home before going to the hospital for examination, and take the child to the hospital for examination after confirming that the child knows how to identify the direction, which will achieve twice the result with half the effort.

In addition, if you encounter the following situations, you need to check as soon as possible:1Premature; 2.Have a family history of strabismus, amblyopia, high refractive error, etc.; 3.Any abnormalities in the appearance or visual appearance of the eyes, etc.

Therefore, it is not necessary to have poor vision or visual abnormalities to go to the hospital for examination, but to check the child's eyesight every year and establish a visual health record, so as to find out whether the child has a tendency to myopia as soon as possible.

If there is a tendency to develop myopia, early intervention and early prevention can be carried out, and even the development of myopia can be stopped.

Under 12 years old.

Pupil dilation is required for the first refraction.

Mydriatic is the process of making the child's eyes completely relaxed through mydriatic drugs and making them lose their regulatory effect. Lan Yuqing introduced that because the younger the child, the stronger the adjustment of the eyes, if the pupils are not dilated during refraction, the adjustment of the ciliary muscle can make the lens convex, the refractive power is enhanced, and the pseudomyopia component cannot be removed, which will affect the accuracy of the examination results.

She stressed that cycloplegic refraction must be done for children under the age of 12, especially for the first time, or for children with farsightedness, strabismus amblyopia and greater astigmatism. Children who have been diagnosed with myopia and need glasses generally need dilated refraction.

Some parents are worried that "dilated pupils are not good for eye health", but in fact, as long as there is no abnormality in the development and structure of the eyes, dilated pupils are very safe. Pupil dilation only helps the eye muscles relax, and when the effect of the drug wears off, it will not cause long-term effects on the eyes, which is safe for most children.

Dilated refraction is a refraction performed when the ciliary muscle of the eye is completely paralyzed by the application of drugs, making it lose its regulatory effect. This is mainly because the juvenile eye has a strong accommodative power, if the pupil is not dilated during refraction, the adjustment of the ciliary muscle can make the lens convex, and the refractive power can be enhanced, and the accommodative myopia, that is, the so-called pseudomyopia, cannot be removed, which affects the accuracy of the results. Therefore, for adolescent myopia patients, dilated refraction is very necessary.

Dilated refraction is mainly used in the following situations: (1) Children under 12 years old. Because of its strong accommodative effect, if the refraction does not dilate the pupils, the error will be very large.

2) 12 4o years old myopia, farsightedness or astigmatism, in principle, the first refraction should be dilated, the second refraction, if the power does not change much, according to the original power of the small pupil refraction after addition or subtraction. (3) The fundus and refractive interstitial examination are normal, but the visual acuity is poor, and it is necessary to use dilated refraction to rule out whether there is refractive error. (4) More complex refractive errors, such as high myopia, high farsightedness or high astigmatism, near or farsightedness combined with astigmatism.

5) Adolescents with unstable vision, good vision for a while, poor for a while, suspected of pseudomyopia. Once this patient dilates the pupils, the accommodation disappears, and pseudomyopia is eliminated.

There are also some cases that are not suitable for dilated eye refraction: (1) Glaucoma patients are contraindicated for dilated refraction, otherwise it will induce an acute attack of glaucoma. (2) Patients suspected of having glaucoma should also be very cautious if the anterior chamber is shallow, the intraocular pressure is high or at the high limit of normal value.

3) Patients over 4o years of age, due to the weakening of accommodation, generally no longer need dilated refraction.

The method of dilated refraction is different for patients of different ages, and the method commonly used at present is as follows: 3 12 years old, apply 1 atropine eye ointment to the eyes, 3 times a day, 3 consecutive days, the fourth day of refraction, and try glasses after 3 weeks; 12 18 years old, 2 post-matropine eye drop, 1 time every 5 minutes, a total of 6 times, 1 hour after refraction, 10 days after spectacle try; After the age of 18, the eyes were spotted with compound tropineamide ophthalmic solution, once every 5 minutes, a total of 6 times, refraction after half an hour, and glasses were tried on the next day.

Dilation of the pupils in children is done to make the prescription more accurate at the time of refraction. The essence of dilated refraction is to relax the fatigue caused by excessive tension of the eye muscles for a long time, so as to obtain the true refractive state of the eye. Dilated refraction is performed when the ciliary muscle of the eye is completely paralyzed by drugs and loses its regulatory effect.

Under the age of 18, children who are getting glasses for the first time must have their eyes dilated and refraction. Because they are likely to have pseudomyopia, (i.e., tension in the eye muscles due to prolonged close learning, but can return to normal after a period of rest.) )

What is the purpose of dilated refraction, and how to choose atropine, Saifeijie, and fast dispersion.

Children's adjustment ability is generally strong, the eyes can not relax without dilating the pupils, the refraction power is inaccurate, after the dilated pupils let the ciliary muscle paralyzed, the eyes relax The power can complete the exposure, and the power will be accurate.

Children's eye adjustment ability is very strong, long-term close use of the eye will lead to muscle spasm around the eyes, the eyes can not be relaxed, resulting in pseudomyopia, the purpose of mydriasis is to paralyze the ciliary muscle, so that the eyes are completely relaxed, eliminate the adjustment factors of the eyes themselves, and expose the true power of the eyes.

Children's accommodative function is relatively strong, ciliary muscle accommodative spasm will have pseudomyopia, mydriasis is through the effect of drugs to make cycloplegic eliminate pseudomyopia to obtain the true power of the eye.

Because if the child is nearsighted, the pupils must be dilated to distinguish between true and false myopia. Dilated pupils are the only criterion for distinguishing between true and false, sexual myopia. It is to instill mydriatic medicine to dilate the pupils, let the ciliary muscles of the eyes relax and then measure the power without adjustment, the most accurate power.

In order to paralyze the ciliary muscle, the power of the dilated pupil is more accurate, and the results of the detection are more accurate, so you must go to a regular eye hospital to refraction the child's optometry and dilate the pupils.

Hello, children are young, strong ability to adjust, pupil dilation is to eliminate the false power caused by excessive tension in the eyes caused by adjustment problems, so as to reflect the child's most real power.

For children's myopia** hospitals, we must pay attention to it, and you mentioned that children's myopia ** hospitals will answer you as follows. It is recognized in the industry that the only way to have a definite effect on myopia is to wear glasses and do surgery, because your situation is higher, younger, and you have to go to school, it is recommended that you use surgery**, glasses are no longer suitable for you, don't be nervous, now excimer laser surgery is very safe, and there will be no accidents in general.

Hello, children are young, the adjustment of the eyes is strong, the purpose of dilating the pupil is to exclude the pseudo-power of eye muscle tension caused by adjustment, so as to know the true power of the child's eyes.

Because children's adjustment ability is very strong, it is easy to affect the refraction results due to their own conditions, so they cannot get accurate refraction results, so they need to use cycloplegic agents to relax the ciliary muscles during refraction, and then through the examination can obtain the true refractive power of the eye.

For example, before the dilated pupils, children's refraction power may be zero, and there may be 200 degrees of farsightedness or myopia after dilated pupils. Therefore, children before the age of 12 need to dilate their pupils for optometry, and the prescription results obtained are relatively accurate. Adults generally do not need dilated refraction.

Hello, children have strong eye accommodation. If there is an abnormality in the adjustment function, the test power will not be accurate. In order to get an accurate diopter, it is necessary to remove the influence of the accommodating factors and let the eyes relax sufficiently, so that the result is a true diopter.

Pupil dilation is generally used for: patients with pseudomyopia, strabismus amblyopia, patients with poor corrected vision, visual fatigue, etc. Hope it helps.

The purpose of mydriasis is to determine the true power of a child's eyes and to determine whether the child is true myopia or pseudomyopia.

This is because: pseudomyopia in childhood, after **, can be recovered; True myopia is timely**, which can reduce the degree of myopia and improve vision.

Expert advice: children with myopia should be taken orally in time, two packs a day, insist on taking it for a period of time, children's pseudomyopia can be recovered, and true myopia will reduce myopia and improve vision.

Suggestions: Yes, at this time, the child's eyes have been completely relaxed, and the excess adjustment has been removed, and the match is the most accurate at this time.

Because children's eyes have a strong ability to adjust, their own adjustment ability may make a simple refraction result error, and the purpose of pupil dilation is to paralyze the ciliary muscle and expose the most true refractive state to determine the result. Therefore, dilated pupils are recommended for adolescents and children who are tested for refractive errors.

Because the child's eyes are not yet mature, they will be affected by many factors during refraction, so dilating pupils before refraction is to make optometry more accurate and glasses more standard.

Hello, adolescence is the period when the human eye is the strongest modulatory, when writing homework, reading books, playing games, the lens in the eye should increase the curvature to increase the power of the eye, which is equivalent to you have to make a pair of glasses for yourself when you see close, so that you can see objects at close range. In order to get accurate results and eliminate pseudomyopia, adolescents under the age of 15 must dilate their pupils before their first optometry.
