Abstract

Purpose: To describe the prevalence and causes of low vision and blindness in a rural population in Northern China. Design: Population-based, cross-sectional study. Participants: A study of 6830 Han Chinese aged 30 years and older was conducted between October 2006 and October 2007 in rural Yongnian County in Handan, Northern China. Methods: Clustered samples of adults aged 30 years or more residing in 13 residential villages were selected randomly and were invited to participate the Handan Eye Study. Participants underwent a comprehensive eye examination, including standardized visual acuity (VA) tests using logarithm of the minimum angle resolution charts. Prevalence was age- and gender-standardized to the 2000 China Census. Main Outcome Measures: Low vision was defined as VA
