title: Anterior chamber depth and its associations with ocular and general parameters in adults.
abstract: BACKGROUND
  To investigate the normative data of anterior chamber depth and its associations in adults in rural Central India.
  
  
  METHODS
  Population-based study.
  
  
  METHODS
  The Central India Eye and Medical Study included 4711 subjects aged 30+ years (response rate 80.1%).
  
  
  METHODS
  The subjects underwent an ophthalmological examination including measurement of the anterior chamber depth by sonography.
  
  
  METHODS
  Anterior chamber depth.
  
  
  RESULTS
  Mean anterior chamber depth was 3.22 ± 0.34 mm. In multivariate analysis, a shallow chamber depth was significantly associated with higher age (P < 0.001), female gender (P < 0.001), shorter body stature (P = 0.003), hyperopic refractive error (P < 0.001), higher lens thickness (P < 0.001) and shorter axial length (P < 0.001).
  
  
  CONCLUSIONS
  In the rural Central Indian population, a shallow anterior chamber was associated with higher age, female gender, short body stature, hyperopia, thick lens and shorter axial length. Compared with population-based data from East Asia (China), the anterior chamber was markedly deeper in India. The data may be helpful to explain anatomic relationships of the anterior segment of the eye, to elucidate risk factors of angle-closure glaucoma and to explain ethnic differences in the prevalence of angle-closure glaucoma.
