Zusammenfassung: | Objective Primary open angle glaucoma (POAG) is the most common type of
glaucoma in Africa. We carried out a study to determine the clinical
presentation pattern of patients with primary open angle glaucoma
(POAG) at a tertiary hospital in Malawi. Design A cross-sectional study
Setting Lions Sight First Eye Hospital-a major referral and
teaching state eye hospital in Blantyre, Malawi Subjects Study
participants were newly diagnosed POAG patients at specialist eye
clinic during study period. Results A total of 60 POAG patients were
recruited into the study. The mean age was 58.7 years (SD= 16.6, range
18 - 86). There were more male (44, 73.3%) than female (16, 27.7%)
patients. The majority of patients (73%) presented one year after onset
of visual symptoms. Twenty-six patients (43%) had unilateral blindness
(visual acuity < 3/60; WHO classification), while nine patients
(15%) presented with bilateral blindness. A vertical cup-to-disc ratio
(CDR) of 0.8 or worse was seen in 92 eyes (79%). The mean intraocular
pressure (IOP) reading was 35.5 mmHg (SD 13.30). Of the thirty-three
eyes that successfully underwent visual field analysis, very advanced
defects were recorded in 12 eyes (36%). Conclusion This study
demonstrates delayed presentation and male predominance among POAG
patients at a tertiary eye hospital in Malawi. Glaucoma intervention
programmes should aim at identifying patients with treatable glaucoma
with particular attention to women. |
