[Expert consensus on stages of public health strategies for myopia prevention and control in children and adolescents].

Myopia has emerged as a public health issue with the increasing prevalence of myopia in children and adolescents in China. In the clinical diagnosis and treatment of myopia, there are clinical stages and classifications, but they are not suitable for the prevention and control of myopia at the public health level. At the public health level, because there is no staging standard for myopia, there is a lack of staging prevention and control guidance for different refractive errors. Therefore, the Public Health Ophthalmology Branch of the Chinese Preventive Medicine Association organized domestic experts in relevant fields to conduct literature searches and discuss based on the research data on myopia at home and abroad, put forward the stages of public health strategies for myopia prevention and control and corresponding group prevention and control measures for each stage to reached this experts consensus. This consensus first proposes a method for assessing myopia risk, in order to predict the occurrence and development of myopia in children and adolescents; From the perspective of public health, myopia prevention and control is further divided into four stages: myopia prodromal stage, myopia development stage, high myopia stage, and pathological myopia stage. According to this consensus, myopia prevention and control technology is targeted and implemented in different stages to provide guidance for myopia prevention and control from the perspective of public health.我国儿童青少年近视患病率居高不下，已成为重大的公共卫生问题。在近视的临床诊治中，有临床层面的分期和分类，但不完全适合公共卫生层面近视的预防和控制。在公共卫生层面，尚无近视防控的策略分期，缺乏针对不同屈光度的分期防控指导。因此，中华预防医学会公共卫生眼科分会组织国内相关领域专家，经过文献检索，基于国内外的近视研究资料进行讨论，提出近视防控公共卫生策略分期，并针对每个分期提出相应群体化防控措施达成本共识。本共识提出近视风险评估的方法，从而对儿童青少年近视的发生发展进行预测；再从公共卫生层面分期为：近视前驱期、近视发展期、高度近视期、病理性近视期，并将近视防控技术针对性落实到不同分期，从而为从公共卫生层面开展近视防控提供指导。.
