Do children with strabismus have to do a dilated refraction test?

Whether you need to dilate your pupils, when you go to the hospital for examination, the doctor will give a reasonable examination opinion.

Common manifestations of strabismus are:

First, it affects the appearance, and normal human eyes are staring at the same target when they see things. Strabismus patients have one eye staring at the target, and the other eye is off the target, which is very unnatural and will also affect the patient's heart. Therefore, the first obvious harm is the appearance, which affects the patient's psyche.

Second, stereoscopic vision is the ability to judge objects far, near or deep and shallow, just like closing one eye up and down the stairs will feel a deep foot, shallow foot is unstable, although the strabismus patient is looking at things with both eyes at the same time, but the target of seeing is different, going up and down the stairs will appear the same feeling as a normal person closing one eye, which is easy to cause physical injury.

Therefore, if the child's eyes are squinted, then it must be paid attention to.

And how the child's eye strabismus is specific, then it depends on the type of strabismus, and the type of strabismus is different, so the method is also different.

Depending on the type of strabismus, it can generally be divided into surgical and non-surgical methods.

1) The surgical method is to adjust the strength of the external eye muscle and the position of the attachment point by surgical means, so that the eye position tends to be normal.

Congenital esotropia (cross-eyed) and upper and lower strabismus usually require surgery**, and non-accommodative and oblique strabismus usually need to be corrected by surgery.

2) Non-surgical method: Not all strabismus requires surgery**, if it is accommodative esotropia, it can be corrected as long as appropriate farsighted glasses or bifocals are worn. If there is also a refractive abnormality of medium to high intensity, it is often necessary to wear glasses to correct it, and axial correction training can be used to help restore monovision and increase the fusion ability of both eyes.

If amblyopia is also present, amblyopia training is also indispensable**.

Strabismus caused by refractive error is recommended to take medication in time to correct the refractive error. It is recommended to take two sachets of Leyan Vision Nutrients every day, and if you insist on taking it for a period of time, the refractive error will gradually be corrected, and the strabismus will gradually improve or even recover.

It doesn't have to be dilated. However, if the pupil is not dilated, the refractionant is required to have a good ability to control and adjust. Those who emphasize pupil dilation should be uncertain about the accommodative power of the tested eye.

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.

If it is the first examination, it is necessary to dilate the pupils, and it is possible to determine whether it is true myopia or pseudomyopia.

Children need to dilate their pupils for the first time in refraction, so as to reduce the error and make the match more accurate.

Hello: The dilated pupil examination is the most accurate and does not harm the child's eyes.

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

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.

To put it simply, mydriasis is to distinguish between true and false myopia.

Pseudomyopia in children can be recovered in time; However, true myopia is irreversible and can only control or reduce the degree of myopia.

The purpose of dilating the pupil is to relieve eye fatigue and relax the muscles that regulate tension, so that the refractive power detected is more accurate. Mydriasis itself does not cause adverse effects on the patient. However, there may be temporary photophobia and blurred vision after pupil dilation (there is no effect on seeing far away, and you can still live normally), and the time to return to normal depends on different mydriatic drugs, tropinkamine generally returns to normal in 4---6 hours, and it takes 3 days for post-matropine, and it can recover on its own after about 2-3 weeks after atropine dilation, and there is no harm to the eyes.

However, it will last for about a month, so it is generally not recommended for children to have dilated pupils frequently.

** Ways to get myopic in children:

1. The maximum number of hours of use of the computer shall not exceed 2 hours each time, and when it must be used continuously, take a break for half an hour for every 2 hours of use.

2. When resting (including usual), first do eye exercises, close your eyes for 10 minutes, and then, gently rub your face and rub your eyes, and then look far away (whether day or night, the purpose is to relax your eyes).

3. To surf the Internet at night, there should be an incandescent lamp of 15 watts in front of the computer. Internet access during the day, and the light in front of the computer should not be too strong. (It is better not to use energy-saving lamps).

Fourth, when reading and writing, you should also pay attention to posture and light.

5. Maintain a certain amount of outdoor activities every day, see more green plants, and look into the distance;

6. Eat less sweets and more purple foods.

The above methods are helpful for the recovery of vision, and the most important thing for children under the age of 18 is to take medication in time for vision loss. It is recommended to take Joyeye Vision Nutrients, take it with warm water, and insist on taking it for a period of time, and your vision will gradually recover.

Hello, the effect of the mydriatic drug itself is not to dilate the pupils, but to relax the ciliary muscles, so that the true power of the child's eyes can be measured. Children's eye adjustment ability is much higher than that of adults. If the pupils are not dilated, the myopia will be too high when the power is measured.

Some children who are not myopic themselves will also be misdiagnosed as myopia. After the child dilates his pupils, he will have photophobia and other reactions, which are normal, and parents do not need to be worried. Parents need to tell their children to avoid bright light exposure after their pupils are dilated, and this situation can be recovered quickly.
