Anterior chamber depth correlated with anthropomorphic measurements: the Beijing Eye Study

Abstract

Background To assess the relationship between peripheral anterior chamber depth and anthropomorphic measurements. Methods The Beijing Eye Study 2006 included 3251 (73.2%) subjects who returned for a followup examination after a baseline examination including 4335 subjects in 2001. The peripheral anterior chamber depth was estimated by slit lamp-assisted biomicroscopy using van Herick's method. Measurements of the body height and weight and assessment of the anterior chamber as inclusion criterion for this study were available for 3191 (98.2%) subjects.Results In a multivariate analysis, a shallow peripheral anterior chamber was significantly associated with higher age (Po0.001), female gender (Po0.001), and shorter height (Po0.001), whereas weight (P ¼ 0.97) and body mass index (P ¼ 0.82) were not significantly associated. Conclusions The peripheral anterior chamber depth was inversely correlated with height, ie, a shallow peripheral anterior chamber may be expected with a higher frequency in short subjects than in tall subjects. Height, in addition to higher age and female gender, may be taken as one of the parameters for screening of subjects being at risk for primary angleclosure glaucoma.

The Beijing Eye Study

“…Central corneal thickness did not vary significantly (p > 0.10) between the optic disc glaucoma ( n = 78 [2.5%] subjects; 551 ± 32μm) and the perimetric glaucoma ( n = 38 [1.1%] subjects; 550 ± 3132μm) groups and the normal group ( n = 3022; 556 ±3332μm) (Xu et al. 2008j).…”

“…As measured by slit‐lamp based optical coherence tomography (OCT) (Xu et al. 2008d), mean anterior chamber depth was 2.42 ± 0.34 mm and mean anterior chamber angle was 38.3 ±16.3 degrees.…”

“…The amount of subcapsular cataract was significantly associated with increased mortality (p = 0.029; OR = 2.14, 95% CI 1.08–4.25), particularly for the subjects aged ≥ 65 years and ≥ 70 years (p = 0.016 and p = 0.003, respectively) (Xu et al. 2008b).…”

“…Of the 16 eyes with glaucomatous optic neuropathy and an optic disc haemorrhage in the 2001 survey, 11 (69%) returned for re‐examination in 2006, and nine (56%) eyes produced examinable photographs (Xu et al. 2009).…”

“…All described associations refer to a multivariable statistical analysis, unless indicated otherwise. Details of the statistical analyses have been described recently (Xu et al. 2005 a–c, 2006 a–g, 2007 a–j, 2008 a–k, 2009).…”
