2019 screening 34,400 schoolchildren with a 36-month follow-up from 2019 to 2021. |
Other: screening
This study included 34,400 students, as part of the Tianjin Eye Study who performed a 3-year follow-up from 2019 to 2021. All participants underwent yearly noncycloplegic refraction and ocular examinations. Time-related changes in sphere, cylinder, and spherical equivalent (SE) measurements in both sexes were analyzed.
