dc.description.abstractBackground: Glaucoma is the second most common cause of blindness worldwide. A disproportionately high number of these patients live in low- and middle-income countries, placing a huge burden on the health care system. The purpose of this study was to describe how glaucoma patients presented to a dedicated glaucoma clinic at a large referral centre/tertiary hospital in central Johannesburg, South Africa. The objectives were to describe the spectrum of glaucomatous disease in these patients as well as the demographics, risk factors and severity of disease in this patient population. The secondary objective was to describe how glaucoma was being managed in the glaucoma clinic patient population. Methods: This study was a retrospective descriptive study which was a clinical audit of the Charlotte Maxeke Johannesburg Academic Hospital’s (CMJAH) glaucoma REDCap database. 787 patient records were included in the study which were patients seen and managed in a 5-year period. This study and the database had valid ethical clearance. Results: Of the 787 patients assessed the mean age at presentation was 59 years (n=739, SD=16), 50.3% were female and 49.7% male. The majority (74.9%) were black African, and the most common diagnosis was Primary Open Angle Glaucoma (POAG) (59%). Patients with secondary glaucoma (excluding exfoliation glaucoma) were significantly younger (49 years +/-18years) whereas patients with exfoliation glaucoma were older (68 years +/-10 years), P<0.001. Black African patients with POAG were significantly younger than other racial groups, p<0.001, with 7% being younger than 35 years. 23.3% of patients had a family history of glaucoma. The median intraocular pressure (IOP) was 15 mmHg (n=690) and median vertical cup to disc ratio (VCDR) was 0.9 (n=605). Using World Health Organisation (WHO) definitions, 32.2% patients had visual acuity (VA) ≤6/120 in the better seeing eye fulfilling criteria for blindness (n=686) and 64.6% of patients had VA≤6/18 in the better eye fulfilling criteria for visual impairment. 68% (n=722) patients were on medical therapy and most patients received on average three agents. There were 426 laser procedures performed, selective laser trabeculoplasty (SLT) accounting for the bulk (65.3%) and 210 glaucoma surgeries were performed. Conclusion: This study supports and reinforces the notion that black South African glaucoma patients are most likely to have POAG, present at a younger age and have more advanced disease with very high rates of visual impairment and blindness. The management of these patients is largely medical with more than one medication. Glaucoma surgery is an important management tool in advanced glaucoma and is being underutilised
