Jinping Xi, as General Secretary of the Central Committee of the Communist Party of China, President of the People’s Republic of China and Chairman of the Central Military Commission, issued important instructions on August 28th that myopia among students in our country presents a trend of high incidence and young age, which seriously affects the physical and mental health of children. This is a major issue concerning the future of the country and the nation that must be stressed and controlled. Through millions of medical optometric data Professor, Yizhi Liu’s team from Zhongshan Ophthalmic Center, Sun Yat-sen University discovered the law of myopia development in Chinese school-aged children.
The prediction model of myopia they created can predict the development of school-aged myopia so precisely that we can take effective intervention to control it. The original paper was published online on the homepage of international medical journal PloS Medicine as cover story on November 6th, 2018.
Limited by the sample size, previous studies on school-aged myopia cannot precisely reflect the law of its development, not to mention the effective prediction and early intervention. Once high myopia occurs, it leads to irreversible damage such as retinal degeneration and even detachment, which seriously affects children’s physical and mental health. If the law of development can be predicted early, the occurrence and development of myopia can be slowed down by increasing outdoor activities and other early intervention means, which is of great significance to reduce the risk of high myopia.
The research team directed by Prof. Yizhi Liu of Zhongshan Ophthalmic Center, associated with a number of hospitals in China, used million-scale medical optometry data through ten years to reveal the law of occurrence, progression and stability of myopia among school-aged children in the real world. On the basis, we can train an artificial intelligence prediction system with random forest to predict the development trend of myopia individually.
The accuracy rate can reach 90% within three years and exceed 80% within ten years. Most surprisingly, a future diagnosis of high myopia can be estimated effectively as early as 8 years in advance. All the results provide scientific evidence for precise intervention of myopia.
In order to transform the research from bench to bed, the research team developed an artificial intelligence cloud platform to provide efficient myopia prediction services. By visiting the intelligent platform and inputting the age and degree of two examinations (at least one year apart), the change of myopia degree and the risk of high myopia in 10 years can be predicted.
Zhongshan Ophthalmic Center of Sun Yat-sen University has been devoted to myopia researc in recent years and made breakthroughs continuously. The achievements aroused increasing social attention and has significant impact. Our previous research on the incidence of myopia among primary and secondary school students (JAMA Ophthalmology, 2018) was reported by foreign media and reprinted as The high incidence of myopia among Chinese students urgently needs intervention by Cankaoxiaoxi. General Secretary Jinping Xi gave instructions after reading this article, “The whole society should take action to take good care of children’s eyes together and let them have a bright future” (Xinhuanet, 2018.08.28). Besides, we have also proved for the first time that increasing outdoor activities can slow down the occurrence and development of myopia (JAMA, 2015), which has been included in the World Health Organization Blue Paper on Myopia Prevention and Control, the National Health Commission’s Eye Health Planning, the Ministry of Education's Youth Myopia Prevention and Control and other policy guidelines.
Our research achievements using big data provide standards for prevention and control of myopia in school-aged children: myopia develops fastest at school age, when we should minimize children’s close reading and increase their outdoor activities. we can never achieve effective prevention and control of school-aged myopia without efforts from the whole society.
