Current Status of Hyperopic Reserve Among Children and Adolescents - 10 PLADs, China, 2020-2024.

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: China exhibits a high prevalence of myopia; however, comprehensive national data based on cycloplegic refraction to assess the current status of hyperopic reserve in children and adolescents remains unavailable.

WHAT IS ADDED BY THIS REPORT?: This study describes different percentiles of spherical equivalent (SE) after cycloplegic refraction for children and adolescents aged 5-18 years across 10 provincial-level administrative divisions (PLADs) and cities in China. SE values declined progressively with age in both males and females, with females demonstrating significantly lower median SE values than males beginning at age 10.

WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: Hyperopic reserve requires systematic monitoring, particularly among females approaching puberty and younger children. Early surveillance by relevant departments is strongly recommended to support comprehensive myopia prevention and control strategies.
