Analysis of Refraction Status of 1 000 Children

Objective To investigate the refractive state of preschool and school-age children. Methods In the First Affiliated Hospital of Kunming Medical University fromJanuary 2009 to December 2012,1000 cases of 3 ~12 years old children(2000 eyes) admitted in the Ophthalmic Outpatient Clinic were enrolled in this study, and they were given retinal screening shadow optometry under cycloplegia, the refractive state was statistically analyzed.Results There were 658 eyes(65.8%) of myopia,296 eyes(29.6%) of hyperopia,and 46 eyes(4.6%) of mixed astigmatism. There were 29 eyes(2.9%) of pre-school myopia,and 629 eyes of post-school myopia(62.9%);128(12.8%) eyes of pre-school hyperopia and 168(16.8%) eyes of post-school hyperopia; 25(2.5%) eyes of pre-school mixed astigmatism and 21(2.1%) eyes of post-school mixed astigmatism. Conclusion Hyperopia is the major refractive error in children aged 3 ~ 6 years old, while myopia is the major refractive error in children aged 6 ~ 12 years old. With the growing age, the incidence and degree of myopia is increasing,amblyopia is more frequent than hyperopia.
