目的：探索超声乳化人工晶状体植入联合房角分离术治疗年龄相关性白内障合并原发性闭角型青光眼(primary angle-closure glaucoma，PACG)患者的疗效。

方法：选取2014-01/2016-01于我院收治的年龄相关性白内障合并原发性闭角型青光眼患者80例80眼，患者平均眼压33.22±3.17mmHg，平均前房深度2.07±0.15mm； 房角镜检查动态下房角关闭≤1/2周。随机平均分为A、B两组进行研究，两组均行超声乳化联合人工晶状体植入术，其中A组联合房角分离术。术后随访2mo对眼压以及前房深度、房角情况进行观察。

结果：两组患者术后眼压及前房深度变化：A组平均眼压15.11±3.67mmHg，前房深度3.11±0.08mm； B组平均眼压17.24±1.67mmHg，前房深度2.76±0.15mm，两组之间比较差异有统计学意义(P<0.05)。两组患者术后房角完全开放比较：A组术后房角全部开放的为28例(70%)，B组术后房角全部开放的为18例(45%)，两组比较差异有统计学意义(P<0.05)。

结论：超声乳化人工晶状体植入联合房角分离术治疗年龄相关性白内障合并原发性闭角型青光眼患者安全可靠，操作简单，不会增加手术风险。

METHODS: Totally 80 patients with age-related cataract merging with PACG were in our hospital from January 2014 to January 2016. The preoperative average intraocular pressure(IOP)was 33.22±3.17mmHg; the average depth of anterior chamber was 2.07±0.15mm; the dynamic situation of primary angle closure ≤1/2 cycle by gonioscope. They were randomly divided into Group A and B for doing a study. All the two groups were treated with phacoemulsification and intraocular lens implantation. And the Group A was with goniosynechialysis. The following up period was 2mo, and we observed the IOP, chamber depth and the anterior chamber angle.

RESULTS: The change of chamber depth and intraocular pressure about the two groups: the average intraocular pressure of the Group A was 15.11±3.67mmHg,the chamber depth was 3.11±0.08mm; those of the Group B were 17.24±1.67mmHg, 2.76±0.15mm respectively; the differences had statistical significance(P<0.05). Postoperatively, there were 28 eyes(70%)in Group A with fully open anterior chamber angle, and 18 eyes(45%)in Group B(P<0.05).

CONCLUSION: The phacoemulsification and intraocular lens implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-dosure glaucoma is safe and reliable. It's simple to operate, and do not increase the risk of surgery.
