In this population‐based screening study, dealing with 1941 persons above 64 years of age from three different municipalities, the overall open‐angle glaucoma prevalence was found to be 8.3%. The prevalence in the separate areas (7.0%, 8.6%, and 9.5%) were not statistically different. Roughly 30% of the population with pseudo‐exfoliation syndrome had glaucoma, and 4.2% had ocular hypertension, whereas the corresponding figures for those without pseudo‐exfoliation were 4% and 0.8%, respectively. The high glaucoma rates are partly due to the high pseudo‐exfoliation prevalence in the area. The prevalence of the capsular glaucoma increased towards a maximum between 75 and 79 years of age, whereafter the curve declined. This may indicate reduced survival time of glaucomatous patients.
