Excuse me, what is the mydriatic medicine? What s the use?

Myopia after mydriasis is true myopia. Don't worry too much about low degrees. Don't use those products. Always pay attention to your eyes. Don't use electronics all the time. Make sure that the reading does not deepen. Take your time and pay attention to protection, and you should get some better.

Pupil dilation is a step taken before refraction to paralyze the ciliary muscle, after paralysis, the ciliary muscle will lose its regulatory effect, and the principle of mydriasis is as follows:

The ciliary muscle in the eye has a regulatory effect that makes the lens convex, and this adjustment can enhance the patient's refractive sense, which will directly lead to the inability to remove the components of pseudomyopia, which will make the refraction results inaccurate.

Especially for adolescent myopia patients, their eyes have a strong ability to adjust, so dilating pupils becomes a necessary step before refraction, which will make the myopia more accurate.

Pupil dilation is often used for fundus examination, optometry and glasses, and there is no harm to the eyes, but in the case of glaucoma, high intraocular pressure, and inflammatory eye disease, it is necessary to carefully choose whether to dilate the pupil. Especially in patients with glaucoma and high intraocular pressure, blind dilation of pupils can lead to glaucoma** or acute attacks, causing further increases in intraocular pressure.

Contraindications must be excluded under the guidance of a doctor before pupil dilation, which can not only achieve the purpose of pupil dilation, but also not provoke the appearance of other eye lesions, which can effectively increase the safety of pupil dilation.

To put it simply, it is to eliminate the refraction error caused by the adjustment.

Because the child's eye adjustment is strong, 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.

Hello, the function of pupil dilation is to relax the eyes, and the ciliary muscles of the swollen eyes have the adjustment effect of making the lens convex, which will enhance the refractive sensitivity and make the refraction results inaccurate.

With dilated pupils, the results of refraction will be relatively accurate when relaxed.

Hello. Dilated refraction is performed when the ciliary muscle of the eye is completely paralyzed by drugs and loses its regulatory effect. Dilated refraction is performed when drugs are applied to completely paralyze the ciliary muscles of the eye, making it lose its regulatory effect.

Pupil dilation is not harmful to the eyes, on the contrary, mydriatic pupils have a certain effect on the so-called pseudomyopia that reads, writes, and regulates spasms at close range for a long time.

The function of mydriasis is mainly to expand the pupil and remove the function of the ciliary muscle, because the contraction of the ciliary muscle will cause us to have the ability to adjust, so that the degree tested is not accurate, after the pupil is dilated, the adjustment force of the ciliary muscle is removed, and then the degree detected is the real degree The result is indeed myopia, we are true myopia, if the degree of myopia is reduced after the mydriasis, it means that the previous degree is the degree of pseudomyopia, and only the degree obtained after the mydriasis is the real degree.

Mydriatic refraction is performed when drugs are applied to completely paralyze the ciliary muscles of the eye, 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.

Our eyes are similar to the lens of a camera, with the ability to zoom. In children and adolescents, the ciliary muscle has a strong ability to adjust, and the adjustment effect can make the lens convex, and the refractive power can be enhanced (thus easy to form "pseudo" myopia with adjustment tension).

If you do not perform dilated refraction, it is difficult to accurately distinguish whether the myopia is accommodative myopia (pseudomyopia) or myopia, and the influence of over-accommodation on the refraction results cannot be eliminated, and the nature and degree of the true refractive state of the eye cannot be accurately determined, which will lead to too low or too high myopia during glasses. Therefore, for children and adolescents with refractive errors, dilated refraction is very necessary. Even at regular check-ups, the doctor will perform a second dilated refraction if necessary, depending on your child's refractive status.

Dilated pupils make your glasses incapable of adjusting. Dilated eye drops can alleviate visual fatigue, and the effect of ** pseudomyopia is better.

Patients with fundus lesions will not be unfamiliar with mydriatic drugs. Mydriatic drugs have a long duration of action, and some only work for one day.

People with myopia often use mydriatic eye drops, which are mostly dropped before going to bed, such as during the day, and the eyes will be blurred. In addition, these eye drops also have the effect of dilating the pupils, and if people with glaucoma use it, there is a risk of blindness, so people must use it with caution.

The mydriatic solution relaxes the pupillary sphincter muscle, allowing the doctor to visualize fundus lesions and perform related tests. In addition, mydriatic drugs can also relax the ciliary muscle, which is mainly used for dilated pupil examinations such as optometry. For rapid mydriatic drugs, the pupils can be dilated in 10-20 minutes to achieve maximum efficacy, and patients will have temporary blurred vision, but the pupils can return to normal in about 8 hours.

Generally, mydriatic drugs include atropine eye drops, atropine eye ointment and other drugs, it is recommended not to use drugs blindly to prevent adverse effects, and blurred vision can occur for a short time after pupil dilation, and you can go to the ophthalmology department of a regular hospital for examination to see what kind of disease it is.

Then carry out the drug**, if it is myopia, you can dilate the pupils, and then refraction, choose the right myopia glasses**, specific** can be carried out according to the doctor's instructions, pay attention to rest, and avoid visual fatigue.

Dilated eye drops are used in some special circumstances, and are rarely used by ordinary people, of course, do not use dilated eye drops without authorization, otherwise, it will have a great impact on the eyes.
