“…5 This estimate is comparable to population studies in other African-descended populations such as St. Lucia, Barbados, Ethiopia and South Africa. [6][7][8][9] In a previous study of patients in the North Eastern region of Ghana, records of 891 eyes of 446 patients were reviewed revealing 98.4% of patients suffered from POAG with 8.3% classified as NTG patients.…”

“…5 To the best of our knowledge, no study in Ghana has yet compared the clinical features of POAG at a rural hospital and an urban hospital in the same manuscript. Our findings highlight the characteristics that have come to define POAG in many African populations: earlier onset, often before the age of 40 years, more severe clinical findings and a more aggressive clinical course with higher rates of blindness.…”

Abstract:Purpose: To compare the clinical features of glaucoma patients who present at a rural hospital in North Eastern Ghana and an urban hospital in the capital city of Accra. Methods: This is a multi-center retrospective case series involving records of newly diagnosed glaucoma patients with emphasis on primary open angle glaucoma (POAG). Information collected included basic demographic data, intraocular pressures and optic disc measurements. Results: A total of 949 patients (437 rural; 512 urban; 1868 eyes) were included. Rural vs. urban comparisons, respectively: mean age, 53.2 ± 16.3 vs. 54.5 ± 16.4 years; male: female ratio, 3:2 vs. 1:1; POAG, 78.1% vs. 50.6%; POAG suspect, 10.3% vs. 41.9%; IOP, 39.2 ± 7.1 vs. 31.8 ± 7.3 mmHg; bilateral blindness, 34.1% vs. 17.5%; uniocular blindness, 52.2% vs. 32.9%. Females at the rural hospital were twice as likely to present blind in at least one eye (OR 2.04, CI 1.36 -3.07, p<0.001). Conclusions:Patients with POAG at the rural hospital present with more advanced disease characteristics.

Purpose This study was to determine factors associated with individuals presenting late with advanced glaucomatous optic nerve damage. Methods A case-control study recruiting 123 patients with early features of primary open angle glaucoma (control) and 93 patients with advanced glaucoma (cases) was carried out for risk-factor analysis. Exposures of interest included those already established as major risk factors for glaucoma. These were initial intraocular pressure (IOP), age, and family history. In addition, occupation, ethnic origin, history of diagnosis of diabetes mellitus, hypertension, sickle cell disease, and previous eye examination were of interest. Results Univariate analysis showed that initial IOP431 mmHg, age of 4 60 years, absence of family history of glaucoma, occupational grouping, ethnicity, and male sex were associated with advanced glaucoma at presentation. Adjusted odds ratio or by multiple logistic regression model showed that initial IOP431 mmHg in a patient was more likely to present with advanced glaucoma (OR 2.66, 95% confidence interval (CI) 1.45, 4.91; P-value 0.0017) than lower pressures. Patients aged 60-69 years (OR 2.53, 95% CI 1.01, 6.31; P-value 0.0473) and 70-90 years (OR 5.16, 95% CI 1.97, 13.51; P-value 0.0008) were more likely to present with advanced glaucoma than younger ones Conclusions Subjects with initial IOP431 mmHg were nearly three times more likely to present with advanced glaucoma than those with IOPo32 mmHg. Subjects over the age of 60 years were more than two times likely to present with advanced glaucoma than younger subjects.

“…3 Seventy-eight respondents (28.6 per cent) had previously undergone vision screening for glaucoma (Table 4), with 38 (13.9 per cent) being screened by optometrists, 27 (9.8 per cent) by ophthalmologists and four (1.5 per cent) by ophthalmic nurses. One respondent was screened by a medical practitioner, while another respondent could not tell who screened him and one was screened by an optician.…”

“…1 Reports indicate that by the year 2020, the number of people with glaucoma will increase to 79.6 million, 1 with an estimated 5.9 million being bilaterally blind. 2 Ghana has been reported to have the second highest prevalence of glaucoma worldwide, 3 with an estimated 700,000 people affected by the disease, of whom over 60,000 are reportedly blind. 4 Primary open angle glaucoma (POAG) is the predominant type of glaucoma in Ghana, affecting 6.8 per cent of the population, with an average age of onset of 30 years.…”

Background In the absence of adequate services, patients have to rely on the few health professionals that they do come into contact with to advise them on their treatment options. The aim of this study was to determine the level of awareness and knowledge of glaucoma, and the association between these factors and self‐care practices among final year health science university students in Ghana. Method A cross‐sectional survey involving the use of a structured questionnaire was conducted among 273 final year students (67 per cent) studying at any one of eight health science programs in three selected public universities in Ghana. Results All 273 respondents were aware of glaucoma but only 37.7 per cent had knowledge of it. The majority (65.9 per cent) defined glaucoma as raised intraocular pressure, and confused glaucoma with ocular hypertension. Over half (56.8 per cent) had acquired their knowledge of glaucoma during the course of their training. The media also played a major role in glaucoma awareness; however, it played a limited role in impacting on the knowledge of glaucoma. Only 28.6 per cent of respondents had previously undergone glaucoma screening. Conclusion Although all respondents were aware of glaucoma, their level of knowledge of glaucoma was low. Self‐care practices were also generally poor among the respondents. This information may be useful for glaucoma health education in Ghana.
