You must have these questions after you find your child’s myopia

Abstract: first of all, we should clarify the role of mydriasis. Because the ciliary muscle of children’s eyes has a strong regulatory ability, not mydriasis will paralyze the ciliary muscle, and the true diopter may be covered up. So, Mydriasis can not only diagnose the types of ametropia (i.e. myopia, hyperopia and astigmatism), but also obtain accurate diopter.

After a summer vacation, many children have the problems of eye fatigue and vision loss. So when a child is nearsighted, the first reaction of parents is to take the child to the hospital, and ophthalmologists generally need mydriasis optometry first. So why mydriasis? Is mydriasis unsafe? How to judge true and false myopia? Does myopia need glasses? Can eye protection reduce myopia?

question 1: why mydriasis?

first of all, we should clarify the role of mydriasis. Because the ciliary muscle of children’s eyes has a strong regulatory ability, not mydriasis will paralyze the ciliary muscle, and the true diopter may be covered up. Therefore, mydriasis can not only diagnose the types of ametropia (i.e. 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 anatomical characteristics of the eyes, The onset of angle closure glaucoma is induced, but it is very rare in children.

question 3: just disperse quickly? Slow dispersion is not good?

and

are called “rapid mydriasis”, which are mainly suitable for older children and adults.

and

are called “slow mydriasis”, which are suitable for young children, especially those with hyperopia, astigmatism, strabismus and amblyopia.

and

are not good or bad. It depends on the child’s age and actual eye conditions!

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.

and

pseudomyopia is functional and mostly occurs in adolescents. Vision can decline in a few weeks or 1 ~ 2 months, and can recover to some extent after appropriate rest.

many parents have illusions that their children are just pseudomyopia. In fact, to judge whether a child is pseudomyopia or true myopia, you can know by doing one thing! That is – normal mydriatic optometry
