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.

ABSTRACT

BACKGROUND: To investigate IOP control following twelve months of continuous medical therapy in Ghana. METHODS: This retrospective case series included 163 glaucoma patients diagnosed at a referral eye center between 1996 and 2006. Information collected included age, gender, IOP at presentation, six months and one year post treatment and types of anti-glaucoma medications prescribed. Optimal IOP control was defined according to results from the Advanced Glaucoma Intervention Study (AGIS), which demonstrated arrest of visual field progression in patients with IOP < 18 mmHg at all visitations: Level 1 (post-treatment IOP ≤ 21 mmHg); Level 2 (≤ 18 mmHg) and level 3 (≤ 16 mmHg). The principal outcome measure was the achievement of IOP <18 mmHg at six months and twelve month visitations. RESULTS: One hundred sixty three patients were analyzed. These included 68 males (41.7%) and 95 females (58.3%). The mean age was 57±16 (median 59 years; range 7 - 95 years). There was no significant difference in age (p=0.35) or mean IOP (p=0.08) between genders. The mean pre-treated IOP of 31.9±8.9 mmHg significantly decreased to 21.3±6.6 mmHg at 6 months (p=0.001), with 57.4% of eyes at Level 1 IOP control, 25.3% at Level 2 and 15.4% at Level 3 and decreased further at 12 months to 20.7±6.9 mmHg (p=0.48) with 69.7% of eyes at Level 1, 34.4% at Level 2, and 12.4% at Level 3. CONCLUSIONS: Current medical regimen is insufficient to reduce IOP to target levels as defined in the Advanced Glaucoma Intervention Study.

Optimal IOP control was defined according to results from the Advanced Glaucoma Intervention Study (AGIS); which demonstrated arrest of visual field progression in patients with IOP 18 mmHg at all visitations: Level 1 (post-treatment IOP . 21 mmHg); Level 2 (. 18 mmHg) and level 3 (. 16 mmHg).

ABSTRACT

Pterygium is a common ocular surface pathology in tropical environments. In the early stages, it may be managed medically with topical anti-inflammatory agents and ocular lubricants. However as the disease progresses, surgical excision becomes necessary and several anaesthetic methods may be used to assist this. We share our experience of a 30-year old woman who underwent uneventful pterygium excision using peribulbar lignocain injection with adrenaline. She developed sudden blindness due to central retinal artery occlusion with macular infarction. While peribulbar anaesthesia is generally safe, a remote risk of retinal vascular accident exists and its routine use should be done with caution. Where possible topical anaesthesia with or without intra-lesional injection be employed.
