How to improve children’s dilated pupil vision?

As we all know, children's eyes have a strong ability to adjust, so when they have their eyes tested, they usually use drugs to paralyze the eyes, which is called mydriasis. The reason for doing this is to effectively protect children's eyes. In order to make the examination results more accurate, it is necessary for children with myopia to undergo mydriasis eye examination.

1. What does mydriasis mean?

What does mydriasis mean? Mydriasis is a step taken before optometry to paralyze the ciliary muscle. After paralysis, the ciliary muscle loses its regulatory function. The working principle of mydriasis is as follows:

1. The ciliary muscle in the eye has the regulatory function of making the lens convex. This regulatory function can enhance the patient's refractive sense, which will directly lead to the inability to remove the components of pseudomyopia, making the results of optometry inaccurate.

2. Especially for adolescent myopic patients, their eyes have stronger ability to adjust, so mydriasis becomes a necessary step before eye examination, which will make the myopia degree more accurate.

3. Nowadays, there are more and more teenagers with myopia, and many of them suffer from eye muscle fatigue caused by long-term use or poor posture, but the symptoms are often similar to myopia. Through mydriasis, this part of pseudomyopia factors can be removed to avoid damage to the eyes caused by inaccurate lens degree. After a period of rest, the symptoms of pseudomyopia can disappear.

4. In addition to myopia, hyperopia patients also need to dilate their pupils, because some hyperopia patients have strabismus and amblyopia problems. By dilating the pupil, the degree of hyperopia can be adjusted more accurately, and amblyopia and strabismus can be corrected to a certain extent.

2. Precautions after pupil dilation

What are the precautions after mydriasis? When the pupil is dilated, the ciliary body in the eye will be temporarily paralyzed. After the pupil is dilated, the symptoms of paralysis may continue. The following points should be noted after the pupil is dilated:

1. During the period of mydriasis, your close-range vision will gradually recover. During this stage, you should avoid any strong light exposure, especially the stimulation of sunlight. If you are going to do outdoor activities, it is best to wear a sun hat or sunglasses.

2. Before the mydriasis has fully recovered, avoid using your eyes, such as reading, watching TV, and using the computer.

3. During the mydriasis period, there will be varying degrees of blurred vision or blurred eyesight. If there is no obvious discomfort, it is still a normal phenomenon. If you feel something is wrong, you should go to the hospital immediately to avoid delaying the disease.

4. During mydriasis, some changes in facial complexion or physical discomfort may occur, such as red face, headache and fever, constipation and nausea, visual hallucinations and excitement, edema and nausea. These symptoms may be adverse reactions to atropine. You should stop taking the medicine immediately and ask a doctor.

5. Even if you stop taking the medication, it will take about three weeks for the pupil to recover. During this period, you need to pay attention to your eyes and avoid eye fatigue.

3. The harm of mydriasis

Are there real dangers of mydriasis? Many parents worry that mydriasis will affect their children's vision before dilating their pupils. First of all, there is no scientific basis for the claim that mydriasis is harmful. On the contrary, it is precisely because of mydriasis that the patient's degree can be measured more accurately.

First, dilated pupils can be fully restored, so there is no need to worry that dilated pupils will have an adverse effect on vision.

Second, mydriasis is not only a means of regulation: it can adjust the ciliary body, thereby eliminating the possibility of pseudomyopia; it is also a means of treatment. Mydriasis can effectively treat pseudomyopia and accommodative esotropia.

Third, the pupil cannot be dilated in the following situations.

1. Glaucoma patients cannot dilate their pupils, which can easily cause acute glaucoma attacks.

2. For patients suspected of having glaucoma, if they are found to have a shallow anterior chamber and high intraocular pressure, it is best not to dilate the pupil.

3. Teenagers generally need to dilate their pupils before eye examination. If the patient is over 40 years old, there is no need to dilate the pupils because the regulatory ability of the ciliary body has weakened.
