Summary: Yes. Children must have mydriasis when they go to the hospital for optometry and glasses for the first time. Because the ciliary muscle of children’s eyes has a strong regulatory ability, if the ciliary muscle is not paralyzed through mydriasis, the true diopter may be covered up.
summer vacation is coming, and the number of small patients in pediatric ophthalmology is increasing day by day. Many parents take their children to the hospital to check their eyesight, optometry and glasses. Because many primary and secondary school students wear glasses for a semester and it’s not appropriate… Children’s myopia is one of the most concerned problems of parents. Every time they see a doctor, they will consult all kinds of questions. Today, Xiaobian will summarize the most frequently asked questions, so that we can have a more systematic understanding of young people’s myopia.
1. Must children have mydriasis examination after myopia?
yes. Children must have mydriasis when they go to the hospital for optometry and glasses for the first time. Because the ciliary muscle of children’s eyes has a strong regulatory ability, if the ciliary muscle is not paralyzed through mydriasis, 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.
2. Will mydriasis harm children?
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.
3. How to distinguish true myopia from false myopia? Both true and false myopia of
showed decreased far vision and good near vision. Pseudomyopia is functional and mostly occurs in children. Vision can decline in a few weeks or 1 ~ 2 months, and can recover to some extent after appropriate rest. True myopia is an organic change and cannot recover naturally.
the only way to identify true and false myopia is to come to a professional eye hospital for mydriatic optometry. After mydriatic optometry, the diopter without myopia is false myopia, and the diopter with myopia is true myopia.
4. What is the difference between fast dispersion and slow dispersion? How should I choose?
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 5 minutes. After dropping it three times in a row and resting for 20 minutes, you can do the initial optometry. It will return to normal 6-8 hours after mydriasis, and then go for a retest the next day.
are called “slow mydriasis”, which are suitable for young children, especially those with hyperopia, astigmatism, strabismus and amblyopia. Atropine eye ointment is generally used. After the doctor prescribes the medicine, the parents point the medicine to the child at home three times a day for three consecutive days. On the fourth day, they come to the hospital for the initial optometry. It is calculated from the date of the initial optometry examination, and then 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.
5. Do you have to wear glasses after myopia?
yes, once diagnosed as true myopia and the degree of myopia is over 75 degrees, you must wear appropriate glasses for treatment. Generally, glasses include frame glasses and rigid hyperoxia corneal contact lenses. Without special circumstances, other methods are not suitable for this age group.
6. Is there any way to control the growth of children’s myopia?
at present, corneal shaping lens is also known as OK lens. It can actively, step by step, gradually and scientifically transform corneal curvature. It has its unique charm in delaying the development of juvenile myopia and effectively controlling early myopia patients. It is an effective non-surgical myopia correction method for adolescents under the age of 18.
7. Is there any way to restore vision after children’s myopia?
after myopia, with the growth and development of children, myopia diopter will only increase but not decrease. Teenagers are generally axial myopia. As the eye axis becomes longer, the degree of myopia gradually increases. Generally, for every 1 mm increase in the length of the eye axis, the degree of myopia will increase by 300 degrees. In adulthood, the degree of myopia can be stabilized within a certain range because the axial length of the eye is no longer increased. Any method can not make the lengthened eye axis shorter, so eye protection will not reduce the degree of myopia.
