Is myopia dilated in children with myopia?_industry news_
Mydriasis is mainly to exclude pseudomyopia, but mydriasis is forbidden for those with glaucoma or increased intraocular pressure. There are also specific situations in which mydriasis is used, and the mydriatics used are also different due to age. The following is mainly to understand the myopia of children with myopia. Because children’s eyes have a relatively strong adjustment ability, mydriatic optometry is mainly to understand whether children’s myopia is true myopia or pseudomyopia. Mydriasis is the use of drugs to paralyze the ciliary muscle, so that it has no adjustment effect, and is undergoing optometry. So you can know the most true refractive state in a static state. If the pupils are not dilated, the ciliary muscles cannot be paralyzed. Under the adjustment of the ciliary muscles, the lens can become convex and the refractive power can be increased. The components of accommodative myopia, the so-called pseudomyopia, cannot be removed, which affects the accuracy of the results. . Therefore, it is necessary for adolescents with myopia to dilate pupils and optometry. Another point is that if you don’t use drugs to paralyze the ciliary muscles, the adjustment effect will cover some of the true degree of power. The younger the age, the stronger the adjustment effect, and thus the higher the true degree of masking. It has a great influence on children's glasses. The negative effects of pupil dilation mainly include the phenomenon of photophobia and myopia blur. Generally speaking, rapid mydriatics need 6 to 8 hours to disappear, and slower mydriasis may take 2 to 3 weeks to disappear. The pupils will return to their previous condition. Very few people will have symptoms such as flushing, dry mouth, dizziness, and palpitation after their pupils are dilated. If it is increased intraocular pressure and glaucoma, it is not possible to dilate the pupil. If the pupil is dilated, the doses used are also different according to the age of the child. A more common practice is to apply 1% atropine ointment to the eyes for 3 to 12 years old, 3 times a day, for 3 consecutive days, refraction on the fourth day, try glasses after 3 weeks; 12 to 18 years old, 2% homatropine Eye drops, once every 5 minutes, 6 times in total, refraction after 1 hour, and try glasses after 10 days; after the age of 18, use compound tropine amide eye drops, once every 5 minutes, 6 times in total, half an hour later Optometry, try glasses the next day. Mydriatic mydriasis is mainly used for children and adolescents with strong accommodative ability and people who have undergone optometry. This category is in patients with myopia, hyperopia, or astigmatism between the ages of 12 and 40. It also includes normal fundus and refractive interstitial examinations, but poor vision The crowd and more complicated refractive errors.
