Abstract

Purpose : To assess the prevalence of refractive error and describe the distribution of axial length and its association with refraction in adult Chinese.

Methods : Random clustering sampling was used to identify adults aged 50 years in Pujiang District, Shanghai. Refraction was determined by objective refraction based on monocular measurement. Axial length was measured by IOLMaster.

Results : Among 1197 participants in the study, data from 1107 phakic right eyes were available for analysis. The prevalence of myopia (SE<-0.5 D), hyperopia (SE>+0.5 D), and astigmatism (cylinder> 0.75 D) was 12.6%, 47.5%, and 67.9%, respectively. The spherical equivalent tended to become hyperopic with age. No difference was observed in the spherical equivalent between women and men. Axial length did not change with age but was consistently shorter in women.

Conclusions : The prevalence of myopia and axial length in this urban Chinese cohort are similar to those observed in previous Chinese. Further studies are needed to clarify the role of environmental factors in the myopia rates.
