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 stud… Show more
“…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).…”

ABSTRACT.Purpose: This review presents and summarizes the findings of the Beijing Eye Study. Methods: The Beijing Eye Study is a population-based study which included 4439 of 5324 subjects (aged ‡ 40 years) who were initially examined in 2001. The study was repeated in 2006, when 3251 (73.2% of 4439, or 61.1% of 5324) of the original subjects participated. Participants underwent a series of examinations including: refractometry; pneumotonometry; biomicroscopy assisted by slit-lamp; optical coherence tomography of the anterior segment; photography of the cornea, lens, optic disc, macula and fundus; blood sampling for laboratory tests; blood pressure measurements, and determinations of anthropomorphic parameters. They were also asked to complete a questionnaire which included questions on socioeconomic parameters, and awareness and treatment of ocular and general diseases. Results: We present normative data for refractive error, anterior segment measurements, intraocular pressure and optic disc structures and their associations, frequency and causes of visual impairment, blindness and visual field defects, prevalences of trachoma, pterygia, open-angle glaucoma and angle-closure glaucoma, cortical, nuclear and posterior subcapsular cataract, age-related macular degeneration, retinal vein occlusions, diabetes mellitus and diabetic retinopathy, myelinated nerve fibres, and retinitis pigmentosa, and associated and risk factors. Discussion: These data may be helpful for dealing with public health issues in China and for assessing associated and risk factors of ocular and general diseases in general.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
