Abstract: mydriasis does no harm to the eyes. Only a small number of people (mostly the elderly) have high intraocular pressure due to mydriasis due to abnormal eye anatomical characteristics, which leads to the onset of angle closure glaucoma. However, children rarely see it.
question 1: why mydriasis?
because the ciliary muscle of children’s eyes has strong regulation ability, without mydriasis, the ciliary muscle will not be paralyzed, and the true refractive power may be covered up. Through mydriasis, we can not only diagnose the types of ametropia, namely myopia, hyperopia and astigmatism, but also obtain accurate diopter.
question 2: is mydriasis safe?
mydriasis does no harm to the eyes. Only a small number of people (mostly the elderly) have high intraocular pressure due to mydriasis due to abnormal eye anatomical characteristics, which leads to the onset of angle closure glaucoma. However, children rarely see it.
question 3: fast or slow?
are called rapid mydriasis, which are mainly suitable for older children and adults. The method is to close your eyes and sit still. The doctor drops the rapid mydriasis solution every 20 minutes. After dropping it twice in a row, you can rest for 40 minutes to do the initial optometry. After mydriasis, it returns to normal 6 ~ 8 hours, and then go for a retest the next day.
are called slow mydriasis. They are suitable for young children, especially those with hyperopia, astigmatism, strabismus and amblyopia. Atropine eye ointment is generally used. Parents point medicine to their children at home. They use it twice a day for three consecutive days. They come to the hospital for the first optometry on the fourth day. Calculate from the date of the initial optometry, and come back to the hospital for optometry on the 21st day. Slow mydriasis can fully paralyze the muscles that control the contraction of the pupil, and the results of optometry will be more accurate. It takes two to three weeks to return to normal after mydriasis. There is no good or bad difference between the two ways of mydriasis. It depends on the child’s age and the actual situation of the eyes.
question 4: is it true myopia or false myopia?
true myopia is an organic change and cannot recover naturally. If the child’s poor eyesight lasts for half a semester or several months, it is likely to be true myopia. Pseudomyopia is functional, mostly in adolescents. Vision can decline in a few weeks or a month or two, and can recover to some extent after appropriate rest. Many parents have illusions that their children are just pseudomyopia. In fact, one thing you can do to judge whether a child is pseudomyopia or true myopia is regular mydriatic optometry. After mydriatic optometry, if there is no myopia, the diopter is false myopia, and if there is myopia, the diopter is true myopia.
