方法：闭角型青光眼患者41例47眼随机分为试验组(聚乳酸防粘连膜植入联合小梁切除术)和对照组(单纯小梁切除术)。术后随访6mo，观察两组患者术后视力、眼压、滤过泡、前房等情况，并进行比较分析。

结果：术后6mo试验组视力不同程度提高，眼压明显降低，和对照组比较，差异有统计学意义(P<0.05)； 试验组88.0%的患者形成功能性滤过泡，显著高于对照组(59.1%)，差异有统计学意义(P<0.05)。

结论：聚乳酸防粘连膜植入联合小梁切除术治疗原发性闭角型青光眼简单、安全、有效。

METHODS: Totally, 41 patients(47 eyes)with primary angle-closed glaucoma were randomly divided into 2 groups. PLA implantation combined with trabeculectony was performed for the experimental group while trabeculectony for the control group. Cases were followed up for 6 months postoperatively, with observation and comparative analysis on visual acuity(VA), intraocular pressure(IOP), filtering bleb and anterior chamber depth.

RESULTS: In the experimental group,6 months after the surgery, VA was improved to different degrees and IOP reduced greatly. According to comparison between the two groups, the differences were of statistic significance(P<0.05). The rate of functional filtering bleb in the experimental group(88.0%)was much higher than that of the control group(59.1%, P<0.05).

CONCLUSION: PLA implantation combined with trabeculectomy for the treatment of primary angle-closed glaucoma is simple, safe and effective.
