To evaluate the risk factors, clinical presentation and surgical outcomes of retinal detachment (RD) among Chinese, Malay and Indian residents in Singapore.
A retrospective descriptive study from January 1995 to December 1998. All RD operations performed at a tertiary ophthalmic center in Singapore were initially identified from a computerized audit database. Case records data of all Malay and Indian patients as well as a 10% randomized sample of Chinese patients were retrieved and analyzed. Tractional and exudative RD's were excluded.
Of the Singapore residents who had a RD operation over the 4-year period, 597 (89.6%) were Chinese, 47 (7.1%) were Malays and 22 (3.3%) were Indians. The age (mean: 46.1 +/- 15.5 years), gender distribution (70.5% males) and presenting visual acuities were similar in the 3 races. The most common site of the retinal break(s) was the superotemporal retina (44.9%), followed by the inferotemporal retina (15.3%). Chinese patients were more likely to have multiple or indeterminate breaks (p = 0.09) and macula-on RD (p = 0.04), compared to Malays and Indians. The distribution of known risk factors (myopia, lattice degeneration, prior cataract surgery and prior ocular trauma) was similar between the three races. The majority of patients required a scleral buckling operation either in isolation (71.3%), or in combination with vitrectomy (19.4%), and only 10 (7.8%) had vitrectomies without buckles. At 6 months postoperatively, anatomical success (defined as an attached retina on ocular examination) and functional success (defined as visual acuities of 6/60 or better) were achieved in 108 (94.7%) and 62 patients (54.4%), respectively, with no significant racial variation seen. The overall rate of redetachment after the initial operation was low (9.3%).
Variation in risk factors, clinical presentations and postoperative outcomes of retinal detachment appears to be minimal among Chinese, Malays and Indians in Singapore.
评估新加坡华人、马来人和印度居民视网膜脱离(RD)的危险因素、临床表现及手术结果。
一项1995年1月至1998年12月的回顾性描述性研究。最初从一个计算机化审计数据库中识别出在新加坡一家三级眼科中心进行的所有RD手术。检索并分析了所有马来和印度患者以及10%随机抽取的华人患者的病例记录数据。排除牵拉性和渗出性视网膜脱离。
在这4年期间接受RD手术的新加坡居民中,597例(89.6%)为华人,47例(7.1%)为马来人,22例(3.3%)为印度人。三个种族的年龄(平均:46.1±15.5岁)、性别分布(70.5%为男性)及就诊时视力相似。视网膜裂孔最常见的部位是颞上视网膜(44.9%),其次是颞下视网膜(15.3%)。与马来人和印度人相比,华人患者更易出现多个或不确定的裂孔(p = 0.09)及黄斑未脱离的视网膜脱离(p = 0.04)。三个种族已知危险因素(近视、格子样变性、既往白内障手术和既往眼外伤)的分布相似。大多数患者单独接受巩膜扣带手术(71.3%)或联合玻璃体切除术(19.4%),仅10例(7.8%)接受了无扣带的玻璃体切除术。术后6个月,分别有108例(94.7%)患者实现解剖学成功(定义为眼部检查视网膜复位)和62例(54.4%)患者实现功能成功(定义为视力达到6/60或更好),未见明显种族差异。初次手术后视网膜再脱离的总体发生率较低(9.3%)。
新加坡华人、马来人和印度人在视网膜脱离的危险因素、临床表现及术后结果方面的差异似乎极小。
