PURPOSE: To estimate the prevalence and risk factors associated with the primary angle-closure disease spectrum in participants of the Colombian Glaucoma Study. METHODS: A cross-sectional study in subjects older than 50 years with a diagnosis of diabetes mellitus or/and systemic hypertension was conducted in Colombia to estimate glaucoma prevalence. This study included 1749 patients and classified them using gonioscopy into either open-angle or primary angle-closure disease spectrum groups. The patients in the primary angle-closure disease spectrum group were then subdivided into the following categories: primary angle-closure suspect, primary angle-closure, and primary angle-closure glaucoma. A logistic regression model was carried out to identify factors related to the primary angle-closure disease spectrum, including age, sex, height, and refraction. RESULTS: The prevalence of primary angle-closure disease spectrum was 19.3% (338) (95% CI: 17.5-21.2). The prevalence of primary angle-closure suspect, primary angle-closure, and primary angle-closure glaucoma was 8.0% (140) (95% CI: 6.8-9.4), 10.1% (176) (95% CI: 8.7-11.6), and 1.2% (22) (95% CI: 0.8-1.9), respectively. In the multivariate analysis, advanced age (+80 years), female sex, and high hyperopia ( = 0.000, 0.021, and 0.001, respectively) were identified as independent factors related to the primary angle-closure disease spectrum. CONCLUSION: A high prevalence of primary angle-closure disease spectrum was found in Colombian patients with a diagnosis of diabetes mellitus or/and systemic hypertension, especially primary angle-closure and primary angle-closure glaucoma. Age, female sex, and high hyperopia were identified as risk factors for the primary angle-closure disease spectrum.
