Summary
Chronic open-angle glaucoma (POAG) is more prevalent in Black subjects (2.1%) than White subjects (0.75%) in Côte d'Ivoire. This eye condition increases with age, highlighting the need for early detection and prevention strategies.
Area of Science:
- Ophthalmology
- Public Health
- Epidemiology
Background:
- Chronic open-angle glaucoma (POAG) represents a significant global health concern.
- Understanding the prevalence of POAG in diverse populations is crucial for targeted public health interventions.
Purpose of the Study:
- To determine and analyze the prevalence of chronic open-angle glaucoma (POAG) in Côte d'Ivoire.
- To compare POAG rates between Black and White subjects within the study population.
Main Methods:
- A retrospective analysis of 33,000 patients (24,751 Black, 8,249 White) attending a private clinic.
- POAG diagnosis based on optic disc cupping (>0.5), abnormal visual fields, and intraocular pressure (>21 mmHg) or normal pressure glaucoma criteria.
Main Results:
- POAG prevalence was 2.1% in Black subjects and 0.75% in White subjects.
- Prevalence increased with age in both ethnic groups.
- Of 571 POAG cases, 81.4% were previously diagnosed, and 38.5% had normal intraocular pressure.
Conclusions:
- Primary open-angle glaucoma is a significant public health issue in Côte d'Ivoire.
- The findings underscore the critical need for enhanced detection and prevention programs for POAG in the region.
