In the end, dilated refraction will not be harmful to the eyes?

Potential hazards are always there, and whoever catches up is unlucky.

The eye sees near or far, and is achieved by focusing or relaxing through the participation of the ciliary muscle of the eye, but in the case of refractive examination, the accommodative function affects the accuracy of refraction. In order to ensure accurate refraction, hospitals or opticians usually use the method of dilated refraction, that is, atropine or tropincamine syrup is used to relax the ciliary muscle, and then refraction is performed to adjust the refractive power of the remaining part.

Adolescents under the age of 15, especially those who are younger, or some adults, especially those who are getting glasses for the first time, need to use dilated refraction to determine the condition of their eyes. Usually, refraction is performed after the infusion of tropincamine is more accurate. Torpicamide mydriade is quick and easy to perform, and refraction can be performed in about half an hour, and the pupil can return to normal after six hours.

For adolescents who are prescribed glasses for the second time, it is generally not necessary to dilate the pupil again, but if the power increases significantly, the pupil dilation test power is still required.

However, pupil dilation should be used with caution for some potential glaucoma patients, and some eye drops such as pupil constriction are also necessary, and commonly used drugs such as pilocarpine, in case of accidents, can be treated in time to solve the painful symptoms caused by glaucoma caused by mydriasis.

Amblyopia examination requires dilated refraction to get the vision of the large pupil, this medicine is generally not *** (dilated pupils should be used with caution for some potential glaucoma patients), that is, the eyes will be uncomfortable after dilation, afraid of light, and it will be fine in a day or two!

It is generally used for children, and it is nothing for teenagers to use it, or to use foggy vision, but there are allergies to mydriatic drugs.

Dilated pupils do not cause any harm to the eyes.

The key is to choose the correct method of dilating pupils, if it is a student, myopia, generally choose rapid dilation, the first day of dilation can be equipped with glasses on the second day, fear of light and uncomfortable symptoms are also very short.

If you have amblyopia, or you are very young, choose atropine for slow dispersion, which is more accurate.

There are also some eye hospitals that have Saifeijie, the effect is better than that of fast dilation, and the pupil recovery is also fast.

If the child is small and does not cooperate with the intraocular pressure measurement, he will use a slit lamp to look at the anterior chamber, this examination is definitely safe, and it is also necessary for students who are wearing glasses for the first time or whose prescription changes quickly.

Myopia in adolescents is mainly caused by prolonged, close proximity, and improper use of the eyes. Especially when reading and writing, I like to put my eyes very close, the adjustment of the eyeball will be strengthened, and over time, it will cause eye swelling and pain, vision loss, that is, the so-called regulatory spasm, if the pupil is not dilated during refraction, the adjustment of the ciliary muscle can make the lens convex, the refractive power increases, resulting in the deepening of myopia. The error of the refractory power will be very large.

Therefore, if adolescents suffer from myopia, dilated eye refraction is necessary when dispensing glasses. Excellent.

The point is: to avoid the juvenile ciliary muscle adjustment too strong, or to loosen the adjustment of spasmodic disorders, so that subjective refraction becomes objective refraction, the power of refraction is more accurate, and the pseudomyopia caused by the adjustment of spasticity is avoided, and at the same time, it also plays a leading role in pseudomyopia. For young children who cannot cooperate well with optometry, a reliable objective index can be grasped after dilating the pupils, so that the myopia degree obtained by refraction is more accurate.

Some children have normal fundus and refractive interstitial examination, but poor vision, and need to use optometry to rule out refractive error. For more complex refractive errors, such as high power of distant and myopic astigmatism, mixed astigmatism, high myopia, high astigmatism, etc., dilated refraction is more needed. Patients with poor vision correction or opacity of the refractive interstitium after small pupil refraction should undergo dilated refraction.

When adolescents have vision loss or unstable vision, and suspect whether there is pseudomyopia, they should dilate their pupils to refraction and rule them out.
