摘要

Myopia has become one of the major reasons for visual impairment in highly urbanized societies of East Asia.In view of the importance of myopia, we conducted our study to examine the prevalence of myopic retinopathy in a large-scale public health care project. The Beijing Eye Public Health Care Project was a population-based study to screen all inhabitants aged 55 years to 85 years and living in the rural regions of the Beijing Municipality. The Ethics Committee of the Tongren Hospital approved the study, and all participants gave informed consent. The Beijing Eye Health Care Project has been in-depth described previously with a detailed description of cataract and other main causes for visual impairment, whereas myopic retinopathy was not specifically addressed.
