“…In agreement with previously reports of glaucoma subtypes presenting in African clinics, [5][6][7][8][9][10][11][12][13][14][15][16][17] our study demonstrates that PACG represents a sizable proportion (Table 2). 3 & Fig.…”

“…Glaucoma is the leading cause of irreversible blindness worldwide. 1,2 Primary open angle glaucoma (POAG) is the most prevalent form, [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] followed by primary angle closure glaucoma (PACG), [5][6][7][8][9][10][11][12][13][14][15][16] which is commonly misdiagnosed. 19 If promptly diagnosed PACG, unlike POAG, is a preventable disease.…”

“…1,[21][22][23] Quigley and Broman (2006) estimate that PACG carries a three-fold increased risk for severe, bilateral visual impairment and is responsible for nearly half of all glaucoma-related blindness cases in the world. Despite literature from the past 20 years consistently showing PACG to be up to 18.5% of presenting glaucomas in ophthalmology departments in the African continent, [5][6][7][8][9][10][11][12][13][14][15][16]24 it has been a commonly held perception that PACG, especially acute angle closure glaucoma (AACG), is rare in African populations. 25,26 In the routine work at the Northern Community Eye Hospital (NCEH) in Tamale, Ghana, a high number of patients presenting with PACG was observed.…”

Précis: In the largest clinic-based study to date, our review of 588 patients presenting with glaucoma in Northern Ghana revealed 36% of these had primary angle closure glaucoma. Purpose: Glaucoma is the second leading cause of blindness worldwide. In Africa, glaucoma is an established public health problem, and primary angle-closure glaucoma (PACG) is not commonly discussed. Recognizing it is important because of its negative impact on visual morbidity, and also because its treatment is different from primary open angle glaucoma (POAG). In response to the observation of many PACG cases at the Northern Community Eye Hospital in Tamale, Ghana, we investigated the proportion of those attending with a first diagnosis of glaucoma who had PACG. Patients and Methods: Using the electronic records, we identified 976 patients who attended with a first diagnosis of glaucoma between January 2021 and October 2022. Of these, 588 met the inclusion criterion of a clear glaucoma subtype diagnosis. Results: Of these 316 (53.7%) had POAG, 210 (35.7%) PACG, and 62 (10.5%) secondary glaucoma. Thus, over a third of presenting glaucomas had PACG. Conclusion: This study highlights that PACG is present in about a third of patients presenting to our clinic in North Ghana . Our study demonstrates the importance of a clear diagnostic pathway including gonioscopy in the assessment of glaucoma patients and the consideration of wider training on angle closure glaucoma diagnosis and management.
