Keywords: open-angle glaucoma, ethnic group, prevalence
|Purpose: To compare the prevalence of open-angle glaucoma (OAG) between different ethnic groups (Mongo, Kongo and other ethnic group) in Congolese patients.
Methods: A cross-sectional study of all patients in a University referral practice (7560 patients) and a general practice of ophthalmology (4172 patients) seen between 1991 and 1995. All patients were categorized by ethnic group (Mongo, Kongo or other).
Results: The distribution of OAG by ethnic group was significantly different between the Mongo ethnic group (5%), and the Kongo (2%) and "other" ethnic groups (2%) (p < 0.00l). There were no significant differences (p > 0.05) between ethnic groups in the mean age (53 years), the predominance of men (sex ratio, 2: l), the mean intraocular pressure (31 mmHg) and the mean cup:disk ratio (0.8) at the time of diagnosis.
Conclusion: OAG seems to be more frequently in the Mongo ethnic group than in others. Further analysis based on poputation-based data may be useful.
