title: [Prevalence of primary chronic open-angle glaucoma in Ivory Coast].
abstract: BACKGROUND
  The aim of this study was to determine and analyze the rate of chronic open-angle glaucoma in Côte d'Ivoire.
  
  
  METHODS
  The prevalence of chronic glaucoma (POAG) was retrospectively evaluated in a population of 33,000 patients attending a private clinic including 24,751 black subjects and 8,249 white subjects. Patients with a cup/disc superior to 0.5 and an abnormal Goldmann's kinetic perimetry, associated with (POAG with "elevated" pressure or not (POAG with normal pressure) with an intraocular hypertension (intra ocular pressure superior to 21 mmHg) were distinguished.
  
  
  RESULTS
  Prevalence was from 2.1% for the black subjects and 0.75% for the white subjects. Mean age was 46.4 +/- 12.5 years for blacks subjects versus 52.8 +/- 12.2 years for white subjects. This prevalence increased with age in both populations. Out of 571 cases of POAG, 465 (81.4%) were previously known and 450 of them were treated; 38.5% of the POAG cases had normal pressure.
  
  
  CONCLUSIONS
  Primary open-angle glaucoma is a major health care problem emphasizing the need for detection and prevention in Côte d'Ivoire.
