Summary
Glaucoma is a significant cause of vision loss, with primary open-angle glaucoma being the most prevalent type. This study analyzed glaucoma
Area of Science:
- Ophthalmology
- Public Health
Background:
- Glaucoma is a leading cause of irreversible blindness globally.
- Understanding the epidemiology of glaucoma is crucial for public health interventions.
Purpose of the Study:
- To assess the prevalence and types of glaucoma among new patients in Benin City, Nigeria.
- To determine the contribution of glaucoma to ocular morbidity in the studied population.
Main Methods:
- Retrospective review of medical records of new patients at University of Benin Teaching Hospital over two years.
- Analysis of patients diagnosed with glaucoma, categorizing them by type and assessing visual impairment.
Main Results:
- Glaucoma was diagnosed in 8.7% of 1,698 new patients.
- Primary open-angle glaucoma (POAG) was the most common type (76.9%), followed by secondary glaucoma (16.3%).
- Blindness due to POAG was noted in 16.8% (visual acuity) and 41.6% (visual field criteria).
Conclusions:
- Glaucoma is a substantial contributor to ocular morbidity in the studied Nigerian population.
- Primary open-angle glaucoma is the predominant form, while primary angle-closure glaucoma is less common.
- Findings highlight the need for glaucoma awareness and management strategies in the region.
