Descriptive statistics summarized the demographic, clinical characteristics and treatment of the participants and determined the association of variables with gender and age. Prevalence of the glaucoma by type, and their 95% confidence intervals (CI) were also calculated.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Result<\/jats:title>\n<jats:p>Of the 5482 case files that were reviewed, 995 (18.15%, 95% Cl 17.15\u201319.19%) had glaucoma particularly primary open angle glaucoma (11.55%, 95%CI 10.73\u201312.42%) and were mostly females (564, 56.7%) aged 69 \u00b1 12 years (range, 50\u2013103 years). In contrast to other glaucoma types, the prevalence of primary angle closure glaucoma (3.68, 95%CI 3.22\u20134.22) increased by 15% over 5 years. The mean intraocular pressure ranged from 15\u201350 mmHg but higher in females than males (27.8 \u00b1 6.1mmHg versus 26.6 \u00b1 6.0 mmHg, <jats:italic>P<\/jats:italic> &lt;0.05) who had comparable VA (0.58 \u00b1 0.4 Log MAR) and cup-disc ratios (<jats:italic>P<\/jats:italic> &gt;0.05). On presentation, the glaucoma hemi field test (GHFT) was outside the normal limits in 45.5% and 54.5% of males and females, respectively. The type of visual field defect was associated with glaucoma type (<jats:italic>P<\/jats:italic> = 0.047). Arcuate scotoma was most common (35.5%) across glaucoma types, paracentral scotoma more common in Secondary glaucoma while Seidel scotoma was highest in NTG (19.3%). Beta-blocker was the mainstay of management (42.2%) but more likely to be prescribed to males while more females received carbonic anhydrase inhibitors.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>The high prevalence of glaucoma in older people remains a public health problem in Nigeria. The fact that about half of the participants presented with visual field defect suggests there is a need for public health messages to emphasize on early glaucoma screening, detection and
