Evaluation of a County-Based Eye Health Service Model in Rural Chinese Children
Recruiting now
Conditions studied: Myopia, Strabismus, Eye Health
In brief
This project proposes to conduct a prospective, multicenter registry study in rural China to evaluate, under real-world conditions, the implementation effectiveness of an integrated child eye health service model centered at the county level and coordinated across county, township, village, and school tiers. The target population will include all children and adolescents within participating counties, and the primary exposure will be the annual coverage and implementation intensity of this service model. The study will focus on its impact on clinical outcomes such as refractive error correction rates and referral rates following eye disease screening, while also examining annual trends in disparities in access to different eye care services. Through long-term and systematic observation, the project aims to clarify the sustained effects of this eye health service model on improving the management of pediatric eye diseases, enhancing visual function, and promoting health equity, thereby providing evidence-based support for optimizing the rural child eye care system in China.
