本文收集了来自10家医院的各类青光眼行小梁切除术427只眼的临床资料。这些病例的随访时间为3个月至5年。简单统计表明，将眼压控制在21 mmHg以下的总体成功率为75%。在随访1年以上的344只眼中，IOP分布显示10家机构中47%的IOP在14 - 19 mmHg之间。这些病例的随访时间为3个月至5年。简单统计表明，将眼压控制在21 mmHg以下的总体成功率为75%。在随访1年以上的344只眼中，IOP分布显示10家机构中47%的IOP在14 - 19 mmHg之间。这些病例的随访时间为3个月至5年。简单统计表明，将眼压控制在21 mmHg以下的总体成功率为75%。在随访1年多的344只眼睛中，IOP分布显示47%的眼睛的IOP在14 - 19 mmHg之间，只有2.3%的眼睛的IOP低于10 mmHg。失败的概率，即平均IOP高于20mmhg超过3个月，采用生命表法计算，该方法考虑了随访期间的多样性。利用威布尔分布函数对累积失效概率进行分析，表明IOP控制失效的时间过程属于早期失效类型；大多数失败发生在一年内。随访5年后，原发性开角型青光眼和原发性闭角型青光眼的最终失败概率分别为0.42和0.48，而先天性青光眼的最终失败概率为0.65。结果表明，老年组第一次小梁切除术后手术失败的概率低于年轻组。同一眼的第二次小梁切除术比第一次手术失败率更高。
The records of a total of 427 eyes with various types of glaucoma treated by trabeculectomy were compiled from 10 institutions. The follow-up periods of these cases were from 3 months to 5 years. Simple statistics gave an overall success rate of 75% in controlling the intraocular pressure (IOP) below 21 mmHg. In 344 eyes followed more than 1 year, the IOP distribution showed that the IOP was between 14 and 19 mmHg in 47% of th 10 institutions. The follow-up periods of these cases were from 3 months to 5 years. Simple statistics gave an overall success rate of 75% in controlling the intraocular pressure (IOP) below 21 mmHg.

The follow-up periods of these cases were from 3 months to 5 years. Simple statistics gave an overall success rate of 75% in controlling the intraocular pressure (IOP) below 21 mmHg. In 344 eyes followed more than 1 year, the IOP distribution showed that the IOP was between 14 and 19 mmHg in 47% of the eyes, and in only 2.3% was the IOP lower than 10 mmHg. The probability of failure, i.e. the mean IOP being higher than 20 mmHg for more than 3 months, was calculated by a life-table method, which takes diversity in the follow-up period into account. An analysis of the cumulative failure probability by Weibull distribution function showed that the time course of failure in the IOP control is of an early failure type; the majority of failure occurred within one year. The final failure probability after the follow-up period of 5 years was 0.42 in primary open-angle glaucoma and 0.48 in primary angle-closure glaucoma, but it was 0.65 in congenital glaucoma. It was shown that the failure probability after the first trabeculectomy is lower in the older age group than in the younger age group. The second trabeculectomy on the same eye showed a higher failure probability than the first intervention.
