METHODS: Survey research. Random cluster sampling was used in selecting individuals aged ≥50 years in 30 clusters in Funing county. Proportions were compared by using the χ2 test and the means compared by using the t-test. Logistic regression was used to detect possible factors of ARMD such as age and gender.
RESULTS: A total of 6 145 persons aged 50 years were enumerated and 5 947(96.78%)participants were received visual acuity test and eye examination. The prevalence of ARMD was 7.53%, with a total of 448 individuals(633 eyes). The prevalence of blindness and visual impairment for presenting visual acuity were 4.13% and 11.96%, respectively. The prevalence of blindness and visual impairment for presenting visual acuity were 4.45% and 7.79%, respectively. Older were significant risk factors of ARMD(OR=1.01, P=0.04).
