In order to actively respond to the requirements of the "14th Five-Year Plan" National Eye Health Plan and further improve the eye health of children and adolescents, on August 13, Aier Eye Hospital Group Yunnan Province held the "Guarding the Window of the Soul and Chasing Dreams" "Light" - Lecture Hall on Myopia Prevention and Control in Children and Adolescents and "White Paper on Myopia Prevention and Control in Chinese Children and Adolescents Big Data" Press Conference (Kunming Station).
At the scene, Xu Jiangtao, deputy director of the Strabismus and Pediatric Ophthalmology Professional Committee of the Ophthalmology Branch of the Chinese Medical Doctor Association, deputy president of Yunnan Province of Aier Eye Hospital Group and president of Kunming Aier Eye Hospital, combined the " White Paper " Myopia Prevention and Control Data, analyzed the current situation of myopia prevention and control in my country in recent years, and combined with the actual situation, popularized scientific eye protection, myopia prevention and control and other related knowledge to children, teenagers and parents, and advocated the whole society to protect children's clear eyes in a scientific way .
5% of 16-year-old children have lost their hyperopia reserve, and the myopia degree of children aged 6-10 has increased the fastest
Recently, the Aier Institute of Optometry and Aier Institute of Optometry of Central South University jointly released the "Myopia in Chinese Children and Adolescents" White Paper on Prevention and Control of Big Data" (hereinafter referred to as the "White Paper"). It is understood that based on the "Global Myopia Big Data Multi-center Research" project previously launched by AIER Ophthalmology, using cloud folders, the "White Paper" collected nearly 9.6 million students aged 6-9 in China, Vietnam, and the United Kingdom. There are valid data, and the eye-using behavior and visual environment of students in the three countries at school and at home are comparatively analyzed from the four dimensions of reading environment lighting, eye distance, proportion and frequency of continuous close eye use, and high-risk close work.
"According to statistics from the "White Paper", the overall myopia rate among children and adolescents in my country in 2021 is 52.7%, the overall myopia rate among British children and adolescents is 36.7%, and the overall myopia rate among Vietnamese children and adolescents is 46.1%. Among them, Chinese children have worse eye behavior at home , 45% of 6-year-old children have lost their hyperopic reserve, and the hyperopia of children aged 6-10 is growing rapidly..." At the event, Dean Xu Jiangtao gave a detailed interpretation of the contents of the "White Paper" based on clinical experience.
She pointed out that judging from the myopia situation in children and adolescents in recent years, the age group with high incidence of myopia has advanced from 8-12 years old to 6-10 years old. Myopia is mainly affected by genetics and environment. Under the same conditions, compared with children whose parents do not have myopia, if one parent has myopia, the child's risk of myopia is about 2.1 times higher; if both parents have myopia, the child's risk of myopia is about 4.9 times higher. Considering environmental factors, myopia may be induced in children by using their eyes for too long, looking at objects that are too small, reading in too bright or dark environments, and using incorrect eye postures. Coupled with parents' insufficient understanding of their children's myopia, the rate of myopia in children is increasing year by year.
"Continuous use of eyes at close distances is a high-risk factor for myopia." Xu Jiangtao interpreted and analyzed that the average eye distance of students from the three countries reached the standard line of more than 70 centimeters "at school" and "at home", but on weekends The average eye distance at home is slightly lower than at school. In terms of the proportion and frequency of continuous eye use, Chinese students use their eyes within 60 centimeters for at least half an hour continuously. Even on weekends, the average total time of close eye use per day exceeds 4 hours. Chinese students spend the longest time working at high-risk close distances (<30>
In addition, reading environment lighting is also an important external environmental factor that affects the development of myopia. The "White Paper" shows that during school hours, the lighting environment of lower-grade students in China is the best, reaching 1687lux, but when Chinese students do homework at home at night, the lighting environment is the best. The lighting environment is the worst (light entering the eyes is 58lux), and the UK is the best.
"With the implementation of school classroom lighting projects by local governments, the lighting environment of schools has been further improved. However, Chinese families' understanding of lighting is far from enough." Xu Jiangtao said that although my country's myopia prevention and control work has achieved certain results, there is still need to Improve the correct understanding of the whole society.
Multi-dimensional, personalized prevention and control of myopia in children and adolescents
"Can myopia be predicted?" "Can myopia be cured?" "What should I do if my child is myopic but doesn't want to wear glasses?"...Parents at the scene They asked Dean Xu Jiangtao questions one after another.
"Once myopia occurs, it is irreversible." Xu Jiangtao said that myopia is an irreversible development process. Once it occurs, the degree cannot be reduced or eliminated. We can only use scientific methods to slow down the growth of the axial length of the eye as much as possible to slow down the increase in myopia and reduce the risk of children becoming highly myopic in the future.
As one of the internationally recognized safe and effective methods to control the progression of myopia, in recent years, orthokeratology lenses have helped many myopic children and teenagers successfully control the progression of myopia.
Xiamen Nanpeng Optical Co., Ltd. specially awarded Kunming Aier Eye Hospital the title of "Orthokeratology Lens Fitting Demonstration Base".
According to reports, orthokeratology lenses use rigid highly breathable contact lenses to gently shape the cornea, flattening the center of the cornea in patients with myopia. They only need to be worn for 8-10 hours at night, and there is no need to wear glasses during the day. , you can obtain clear naked-eye vision; after you stop wearing it, the shape of the cornea will gradually return to its original (before wearing it) state.
However, Xu Jiangtao also reminded that the fitting of orthokeratology lenses needs to strictly control the indications. Not all myopia people are suitable for wearing them, and the fittings need to be standardized. "Orthokeratology lenses are the same as heart valves and heart stents , both belong to the national Class III medical devices . According to the regulations of the health department, orthokeratology lenses must be fitted in medical institutions with a "Medical Institution Practice License" level 2 or above. "
It is understood that this event will be followed up. It will also continue to cooperate with the "Eye" color in 10 hospitals in 8 cities and districts of Aier Eye Hospital Group in Yunnan Province to help more children and teenagers protect their eyes and pursue their dreams.
