Anyang Childhood Eye Study (ACES )
The ACES is a school-based cohort study designed to longitudinally observe the occurrence and development of myopia as well as other ocular diseases in school-aged children. Anyang, a small prefectural-level city in China with a population of 5.42 million and an area of 7,413 square kilometres, was chosen as the study area due to its relatively stable demographic structure, similar socioeconomic status to the national average, and location in central China, which is the cradle of Chinese culture. The study sample consisted of 2,893 grade 1 and 2,267 grade 7 students. The mean age of the grade 7 students examined was 12.7 years (range 10.0–15.9 years), and boys accounted for 50.0%. For the grade 1 students examined, the mean age was 7.1 (range 5.7–9.3 years), and boys accounted for 57.8%.
