Juvenile myopia, why must mydriasis?

Abstract: teenagers have strong eye regulation. If the pupil is not expanded during optometry, the regulation of ciliary muscle can make the lens convex and enhance the refractive power. The components of regulatory myopia and so-called pseudomyopia cannot be removed, which will affect the accuracy of the results. Therefore, mydriatic optometry is very necessary for young people with myopia.

mydriatic optometry is performed when drugs are used to completely paralyze the ciliary muscle of the eye and make it lose its regulatory effect. Why optometry? What are the conditions that need mydriatic optometry? What are the conditions that are not suitable for mydriatic optometry? Does mydriasis affect children?

1 why mydriasis?

this is mainly because teenagers have strong eye regulation. If the pupil is not expanded during optometry, the regulation of ciliary muscle can make the lens convex and enhance the refractive power. The components of regulatory myopia and so-called pseudomyopia cannot be removed, which will affect the accuracy of results. Therefore, mydriatic optometry is very necessary for young people with myopia.

1. Cases requiring mydriatic optometry

1. Children under 12 years old. Because of its strong regulating effect, if the pupils are not dilated in optometry, the error will be very large.

2. For patients with myopia, hyperopia or astigmatism aged 12-40, in principle, mydriasis is required for the first optometry, and for the second optometry, if the degree changes little, it can be added or subtracted after small pupil optometry according to the original degree.

3. Fundus and refractive stroma examination are normal, but visual acuity is poor. Mydriatic optometry is needed to rule out the presence or absence of ametropia.

4. More complex refractive errors, such as high myopia, high hyperopia or high astigmatism, myopia or hyperopia combined with astigmatism.

5. Teenagers have unstable eyesight. Their eyesight is good for a while and poor for a while. They are suspected to be pseudomyopia.

1 does mydriasis affect children?

mydriasis has only a time impact on children. Generally speaking, slow mydriasis takes longer (about 21 days), but the effect is also better. It is the final degree determined by “retinoscopy” after “atropine” eye point. This method is more suitable for young children and children with hyperopia and amblyopia.

and

disperse quickly (about 1 day). This method is suitable for ordinary children. It will not affect children’s normal learning. Just take two days.

and

children will feel photophobia, blurred vision and other symptoms after mydriasis. These symptoms are normal and can be recovered after a period of rest.

is the first choice for children’s myopia.

is an effective means to control juvenile myopia. It is a process to promote the gradual deformation of corneal morphology to a more reasonable shape. It uses high oxygen permeability materials to design and manufacture a special hard contact lens whose geometry is opposite to the shape of the front surface of human cornea. By wearing it on the eye surface before going to bed, it produces slight compression, slowly changes the corneal shape, and flattens the central optical area of cornea, so as to achieve the effect of reducing myopia and astigmatism.

and

corneal shaping lenses have significant effects on the correction of various refractive errors and the control of myopia in children and adolescents. The biggest advantage is to wear them at night and take them during the day, correct myopia in sleep, control the rapid development of myopia, and the effect of controlling the development of myopia is five times that of frame glasses. The annual increase of myopia can be controlled at about 25 degrees, and some children’s myopia does not even increase.

and

corneal shaping lenses are suitable for which groups?

people aged 1, 7-40 who are unable to do myopia surgery or unwilling to do myopia surgery, do not have corneal, conjunctival diseases or other eye diseases, and do not have serious systemic diseases.

2. Myopia degree is within 600 degrees and astigmatism degree is within 150 degrees.

3. The degree of myopia in children and adolescents has increased rapidly.

4. They like to participate in sports and entertainment activities and are not used to wearing frame glasses.

5. Some special occupations, such as military and police personnel, divers and pilots, are not convenient to wear any glasses and are not allowed to perform myopia surgery.

6. Parents suffer from high myopia and their children have a genetic trend.

and

experts specially remind that the fitting process of corneal shaping lens is very rigorous and scientific. Only professional eye hospitals have professional medical equipment to ensure its safety and effectiveness. Here, we remind the parents of children that the fitting of corneal shaping lens must be carried out in a professional hospital.
