| description | To evaluate the prevalence of age-related maculopathy (ARM) in adult Chinese living in rural or urban regions of mainland China.
Population-based prevalence study.
The study included 4439 subjects (aged 40 or more years) out of 5324 subjects invited to participate (response rate 83.4%). It was held in rural and urban regions of Greater Beijing. The participants underwent a detailed ophthalmic examination including fundus photography. All fundus photographs were graded by the Wisconsin Age-Related Maculopathy Grading System.
Fundus photographs were available for 4376 (98.6%) subjects. Early ARM was present in 122 (1.4%) of 8655 (95% confidence interval [CI] 1.16% to 1.66%) eyes or 63 (1.4%) of 4376 (95% CI 1.09% to 1.79%) subjects, late ARM in 12 (0.14%) of 8655 (95% CI 0.06% to 0.22%) eyes or seven (0.2%) of 4376 (95% CI 0.04% to 0.28%) subjects, and exudative ARM as part of late ARM in seven (0.1%) of 8655 (95% CI 0.02% to 0.14%) eyes or six (0.1%) of 4376 (95% CI 0.03% to 0.25%) subjects. The prevalence of early ARM, late ARM, and exudative ARM, respectively, increased from 0.61%, 0.07%, and 0.07% in the 40-to-44-year age group, to 1.66%, 0.26%, and 0.26% in the 55-to-59-year group, and to 2.99%, 0.90%, and 0.60% in the group aged 75 years and older.
