What are the effects of dilated pupils on the eyes?

There are two categories of mydriatic pupils in ophthalmic applications, one is to use dilated pupils to help check the fundus when looking at the fundus, and the second is to judge that children are myopic and farsighted, if it is to help determine that when the refractive error occurs, the dilated pupils have no effect on children, and it is helpful to children, it can help determine whether it is myopia, farsightedness or astigmatism, and when helping older people to examine the fundus, if there are no other contraindications such as shallow anterior chamber, mydriatic pupils do not cause any damage to the eyes, It is also an important test to help confirm the diagnosis.

There is no obvious harm to the eyes.

When performing eye examinations, for example, to see lesions in the fundus, especially those around the retina, it is necessary to spread the pupils to see the surrounding lesions. Some adolescents and children, if they find myopia, also need to dilate their pupils, and they need to paralyze the ciliary muscle to remove the components of pseudomyopia.

The general mydriatic drugs only play a local role, and the impact on the whole body is relatively small. In addition, the action time is relatively short, only about 4 to 6 hours, after these hours, the pupil can completely return to normal.

Dilated pupils are not very harmful to the eyes, but they are not guaranteed. After eliminating the problem of glaucoma, there is little harm. After dispersing today, if there is a problem tomorrow, you can also disperse again without too many problems.

If it's slow, like atropine, there may be some ***. Because if you use it for three days, you will have the effects of atropine, such as sweating, flushing, and fever. After stopping the drug, it will get better and there won't be too many problems.

So in general, dilated pupils don't hurt the eyes much.

There are no ill effects. Rapid mydriatic agent 8 to 10 hours after the dilation of the pupil, the near vision is not clear, fear of strong light, generally the next day to return to normal.

The main purpose of pupil dilation is to relieve eye fatigue, regulate the function of the ciliary muscle, and relax the tense muscles, so as to achieve the effect of accurately measuring the refraction of the eye. The dilated pupil itself does not cause harm to the eyes, it is just a way to check. However, most patients may experience transient photophobia and blurred vision after dilation, but they can recover spontaneously.

Therefore, it is safe to perform a dilated eye examination.

The dilated pupil of dilated refraction is only a superficial phenomenon, and the essence of dilated pupil is to make the ciliary muscle completely relaxed, relaxed and adjusted, so as to obtain the true refractive state of the eye. Pupil dilation does not leave any discomfort and does not have a long-lasting effect on the eyes.

After the pupil is dilated, the child will have temporary photophobia, difficulty in seeing near and other symptoms, and the effect of the rapid mydriatic agent will disappear after 6 to 8 hours, and the pupil will return to the same as before. Slow-mydriatic agents, i.e., atropine, may take 2 to 4 weeks for their effects to wear off.

The purpose of dilating pupils is to paralyze some muscles of the eyes, so that it can go from a state of tension to a relaxed state, at this time the pupils will be dilated, and the doctor can do some follow-up examinations under the condition of dilated pupils, the most common examination is optometry and fundus examination.

Pupil dilation generally has no effect on the eyes, and pupil dilation can sometimes lead to some eye diseases, such as pigmentitis and other diseases.

Dilated pupils can dilate the pupils, and the eyes will have a sense of double vision blurring for a short time after the drop, and the discomfort will disappear after about a day.

Pupil dilation is to let the ciliary muscle contract, pupil dilation, can distinguish true and false myopia, can also facilitate surgery, after the dilation of pupils, the vision will be blurry, wait for the pupil to recover.

Eye dilation is not harmful to the eyeball itself, not only is there no harm, but it plays a role in relaxing the eyeball and preventing further myopia.

Correct dilation of the pupils according to the doctor's instructions is generally not too harmful to the child. After doing mydriasis, you need to pay attention to avoiding light, rest more, after dilating pupils, the near objects may be a little blurry, and the eyes should be reasonably arranged for study and work.

It is generally harmless, and sometimes it is even a means of dilating the pupils for eye diseases (such as pigmentitis).

Normally, dilated eye examination is not harmful to the eye, but in patients with angle-closure glaucoma, dilated examination may induce it.
