可拆褥式缝线小梁切除术的远期疗效观察——寿命表法分析

Long term observation on the clinical effects of trabeculectomy with removable sutures-Life - span table analysis

目的:应用寿命表法评价可拆褥式缝线小梁切除术后远期疗效。方法:对63例(82只眼)青光眼患者在表面麻醉下行;巩膜瓣可拆褥式缝线小梁切除术,术后3-14天拆除巩膜瓣缝线.用寿命表法分析术后远期疗效。结果:得出各年成功率及成功率曲线,术后5年成功率分别是:40只眼原发性开角型青光眼为(67.91±5.3)%,42只闭角型青光眼为(68.34±6.1)%,眼压失控主要发生在手术1年以内。结论:寿命表法客观准确地反映了整个随诊期不同时点的真实情况,对长期追踪的病例进行研究,是一种较为科学的纯计方法,值得推广。

Objective:To evaluate the long term clinical effects of trabeculectomy with removable stitches suture by using life - span table analysis, and also to confirm whether the operation could effectively reduce the complication and improve the optical functions. Methods: 63 patients with glaucoma (82 eyes) underwent trabeculectomy with removable stitches suture after topical anaesthesia. The stitches were removed 3-14 days postoperatively. The long term clinical effects were assessed with life - span table anlalysis. Results: The success rate and the success rate curve were obtained. The 5 years operative success rates were (67.91 + 5.3) % in primary open angle glaucoma (40 eyes) , and in close angle glaucoma (42 eyes), (68.34 ± 6.1)%. Loss of control of intraocular pressure mainly occurred within one year postoperatively . Conclusion: Life - span table analysis method can objectively and accurately present the real optical con - ditious at different time point during follow - up period. The long - term follow - up of the cases was a comparatively scientific statistical method and the experience was worthy of publicity.
