OBJECTIVE: To determine frequencies of various types of glaucoma in an urban community of Congo. METHODS: The records of 176 patients with the diagnosis of glaucoma examined between 1991 and 1995 at a non-university center were reviewed. A complete ophthalmological examination was performed in each patient including best visual acuity, refraction, slit-lamp examination, ophthalmology and intraocular pressure measurements. Gonioscopy and visual field examination were performed when needed. RESULTS: The frequency distribution of the various subtypes of glaucoma was: open-angle glaucoma (72.2%), aphakic glaucoma (9%), uveitis glaucoma (6%), exfoliative glaucoma (3%), glaucoma secondary to ocular trauma (2.2%), cataract glaucoma (1.7%), normal tension glaucoma (1.7%), congenital glaucoma (1.7%), neovascular glaucoma (1.3%), pigmentary glaucoma (0.6%), corticosteroid-induced glaucoma (0.6%), and glaucoma associated with retinoblastoma (0.6%); CONCLUSION: Despite the limitations inherent of a retrospective review of records, our study provides an indication of the prevalence of various types of glaucoma in a urban community of Congo. This study confirmed also the rarity of primary angle-closure glaucoma in the black.
