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 6 3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 :4 0只眼原发性开角型青光眼为 (6 7 91± 5 3) % ,4 2只闭角型青光眼为 (6 8 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 ,是一种较为科学的统计方法 ,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 analysis.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 conditions 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.
