Is mydriasis harmful to amblyopia, and is dilated pupils harmful to the eyes

There is no harm. In the case of normal intraocular pressure, pupil dilation is the use of drugs to completely relax the eyes, the real power of the eyes is completely exposed, when the glasses need to be changed, the choice of glasses power has a good reference role, and the optometrist then measures a reasonable power according to the child's eye position, which is necessary to improve the vision of the amblyopia eye.

Dilated pupils do not cause any harm to the eyes. Pupil dilation is usually needed when refractioning an adolescent's eyes. In order to avoid the interference of ciliary body adjustment and make the refraction more accurate, doctors generally recommend dilated refraction, that is, the use of cycloplegic drugs to numb the ciliary muscle in the eyeball first, so that the regulatory effect of the ciliary muscle is fully eliminated.

In order to fully reveal the diopter of the eyeball, so that the doctor can fully understand the true refractive state of the eye and give the appropriate prescription glasses.

Some parents may be concerned about blurred vision after dilated refraction. After the dilation of the pupils, the pupils are in a dilated state because the drug has not completely disappeared, and the ciliary muscle is still in a state of paralysis and the adjustment effect is suspended. Therefore, it is normal for children to see things with blurry vision or to feel glaring at slightly stronger light, and there is no need to worry too much.

As the effect of the drug slowly wears off, usually two to three weeks, this condition will naturally disappear.

Pupil dilation has no effect on the eyes. Generally speaking, mydriasis is only a temporary dilation of the pupil of the eye, and then it can accurately determine the disease of the eye. After the drug is metabolized, the normal pupil size can naturally be restored, and the corresponding ** should be done according to the reason for the examination.

When people examine their eyes, they need to put a certain specific thing in the eye, which can help people achieve the effect of dilating their pupils.

Pupil dilation can help people's ciliary muscles relax and allow the eyes to reach a refractive state, in this case, the measured vision of the eyes is closer to people's normal conditions, which can effectively help people wear glasses.

Because there are some children who are prone to pseudomyopia, it is more effective to use this method in order to allow people's vision to be truly monitored.

The use of dilated pupils in ordinary life can help relieve some of the pressure on the eyes, but the dilated pupils may also cause a certain amount of discomfort to their own physical health, so let's take a look at the related hazards of dilated pupils in ordinary life, let's take a look.

Dangers of mydriasisPupil dilation is a good way to promote the dissipation of eye discomfort, and there are many people with pseudomyopia who will choose to use the way of mydriasis, which can well promote the effect of their pseudomyopia relief, which is more effective than some acupuncture or ear acupuncture and other methods, which can make the human body's eye blindness return to normal in a short period of time, but it is also possible to cause their own eye vision to be less than 0.8 when they are naked after dilation. At this time, it is a kind of true myopia, and mydriatic pupils will cause changes in the anterior and posterior axes of their own eyeballs, resulting in myopia, so there are certain disadvantages about mydriatic pupils in ordinary life, so it is necessary to pay attention to them in ordinary life.

Although pupil dilation can help our eyes to get a certain buffer for some uncomfortable symptoms, but the same words will also lead to some damage to our own eyes, and the occurrence of true myopia, so we still need to pay attention to the use of mydriasis to improve the symptoms of eye discomfort in daily life, so as not to cause certain adverse effects on our physical health.

Is the danger of mydriasis really there? Many parents are worried that dilated pupils will affect their children's vision. First of all, there is no scientific basis for the harm of mydriasis, on the contrary, it is the mydriasis that makes the patient's prescription more accurate.

First, dilated pupils can be fully recovered, so there is no need to worry about the adverse effects of dilated pupils.

Second, mydriasis is not only a means of adjustment: it can adjust the ciliary body, thereby ruling out the possibility of pseudomyopia; At the same time, it is also a means of dilation, which can effectively lead to pseudomyopia and accommodative esotropia.

Thirdly, the pupils should not be dilated in the following cases.

1. Glaucoma patients cannot dilate their pupils, which is easy to cause acute glaucoma attacks.

2. Patients with suspected glaucoma, if they find that the anterior chamber is shallow and the intraocular pressure is high, it is best not to dilate the pupils.

3. Adolescents generally need to dilate their pupils before refraction, if they are patients over 40 years old, because their ciliary body's adjustment ability has been weakened, there is no need to dilate their pupils.

Suggestion: Mydriasis refers to the use of drugs to produce two physiological changes in the eye: cycloplegia and mydriasis. Due to the strong effect of eye accommodation, it is difficult to find out whether it is really myopia if the eye is not paralyzed and the pupils are dilated.

Because pupil dilation will bring temporary inconvenience to the examinee, and incorrect follow-up maintenance will also cause eye discomfort and infection, it is important to understand the precautions after pseudomyopia mydriasis in adolescents.

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. After dilating the pupils, the eyes can be in a resting state, and can also be used to prevent and treat myopia.

However, care should be taken to shield in bright light to reduce UV intake.

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.
