County-centered eye health service model for rural children in China

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective, multicenter registry will enroll children aged 3–18 who are residents or school enrollees in five participating counties and will track annual coverage and implementation intensity of a county-level integrated eye health service. The model coordinates care across county, township, village, and school tiers and uses school-based screening as a core intervention to detect refractive error, amblyopia, and strabismus. Primary outcomes include rates of refractive error correction (spectacle coverage) and referral rates after screening, and the study will analyze annual trends and disparities in access to eye care services under real-world conditions. Long-term systematic observation aims to clarify sustained effects on pediatric eye disease management, visual function, and equity of service delivery.
