To determine the epidemiology and recurrence rate of pterygium after excision using bare sclera technique.
Prospective non-comparative study.
Ophthalmology unit, Korle-Bu Teaching Hospital, Accra, Ghana.
The study involved 60 consecutive patients with primary apterygial from July 1998 to December 2000 who had bare sclera excision after informed consent. They were post-operatively followed up for 30-months.
Thirty-five patients (58%) were females. The patients' ages ranged from 17-75 years, mean (±12.6). Overall recurrence was 22(37%). The main complications encountered include were granuloma 20 %(n=12), restriction in medial rectus muscle motility 2(3%), persistent vascularisation at excision site 2(3%) and adherence leucoma with uveitis 1(2%). No significant association was found between recurrence and pterygium morphology, calcification, allergy and occupation (indoor or outdoor).
The recurrence rate after pterygium excision using bare sclera technique in Ghanaians is high (37%).
确定采用单纯巩膜技术切除翼状胬肉后的流行病学特征及复发率。
前瞻性非对照研究。
加纳阿克拉科勒-布教学医院眼科。
该研究纳入了1998年7月至2000年12月期间连续60例原发性翼状胬肉患者，这些患者在签署知情同意书后接受了单纯巩膜切除术。术后对他们进行了30个月的随访。
35例（58%）为女性。患者年龄在17 - 75岁之间，平均（±12.6）岁。总体复发率为22例（37%）。主要并发症包括肉芽肿20%（n = 12）、内直肌运动受限2例（3%）、切除部位持续血管化2例（3%）以及伴有葡萄膜炎的粘连性白斑1例（2%）。复发与翼状胬肉形态、钙化、过敏及职业（室内或室外）之间未发现显著关联。
在加纳人当中，采用单纯巩膜技术切除翼状胬肉后的复发率较高（37%）。
