Methods
The Beijing Eye Study is a population-based cross-sectional study in Northern China. It was carried out in four communities in the urban district of Haidian in the North of Central Beijing and in three communities in the village area of Yufa of the Daxing District South of Beijing. The study has been described in detail recently.6, 7 At the time of the first survey in the year 2001, the seven communities had a total population of 5,324 individuals aged 40 years or older. In total, 4,439
Results
Out of the 3,251 subjects of the Beijing Eye Study 2006, OCT measurements of the ACD and chamber angle were available for 2,985 subjects (91.8%) (Table 1). Mean age was 60.2 ± 10.0 years (median, 60 years; range, 45 to 89 years), mean refractive error was –0.32 ± 2.17 diopters (D).
Including all participants of the Beijing Eye Study 2001 (n = 4,439) and comparing the subjects with OCT measurements (n = 2,985) with the subjects without OCT measurements (n = 1,454) showed that the group without
Discussion
The present population-based study on mainland Chinese living in the greater Beijing area suggest that a shallow ACD is associated with higher age, hyperopic refractive error, female gender, short body stature, small optic disk, presence of arterial hypertension, and thicker central cornea (Table 4). Correspondingly, the ACA became narrower with increasing age, hyperopic refractive error, female gender, shorter body height, small optic disk, nuclear cataract, and presence of chronic
