方法：选取2015-02/2016-02在我院治疗的原发性急性闭角型青光眼患者62例62眼，其中对照组34例34眼(术前眼压控制在正常范围，眼压≤21mmHg)，观察组28例28眼(术前眼压28～50mmHg； 高眼压持续3d以上)。两组均行复合式小梁切除术，观察两组患者手术前后视力、眼压等变化。

结果：观察组术后3mo视力较术前提高、不变和下降的比例分别为68%、21%和11%，与对照组比较差异无统计学意义(P>0.05)； 两组术后眼压均较术前明显减小，差异有统计学意义(P<0.05)； 观察组和对照组术后眼压分别为11.10±2.20、11.73±2.71mmHg，差异比较无统计学意义(P>0.05)； 观察组术前及术后前房深度均低于对照组，差异有统计学意义(P<0.05)； 两组术后前房深度均较术前有所增加，差异有统计学意义(P<0.05)； 两组术后眼轴长度均较术前有所减少，差异有统计学意义(P<0.05)； 观察组术后并发症发生率为14%，对照组并发症发生率为18%，差异比较无统计学意义(P>0.05)。

结论：高眼压下原发性急性闭角型青光眼行复合式小梁切除术是有效的，但仍需进一步研究。

METHODS: From February 2015 to February 2016, we selected 62 cases(62 eyes)of primary acute angle closure glaucoma in our hospital, the control group 34 patients 34 eyes(preoperative intraocular pressure control in the normal range, intraocular pressure ≤ 21mmHg), the observation group 28 patients 28 eyes(preoperative intraocular pressure not in the normal range, the intraocular pressure 28-50mmHg and lasted for more than 3d). The two groups were treated with compound trabeculectomy and observed for visual acuity, intraocular pressure and so on.

RESULTS: Compared with preoperative, at 3mo postoperatively visual acuity improved, unchanged and decreased rate in observation group were 68%, 21% and 11%, the difference were not statistically significant compared with the control group(P>0.05). The postoperative intraocular pressure of the two groups compared with preoperative significantly decreased(P<0.05). The postoperative intraocular pressure of observation group and control group were 11.10±2.20mmHg and 11.73±2.71mmHg, the difference was not statistically significant(P>0.05). The preoperative and postoperative anterior chamber depth of observation group was lower than that in the control group(P<0.05). The postoperative anterior chamber depth of the two groups compared with preoperative increased(P<0.05). The postoperative axial length of the two groups compared with preoperative decreased(P<0.05). The postoperative complication rate of observation group was 14%, and the control group was 18%, the difference was not statistically significant(P>0.05).

CONCLUSION: Compound trabeculectomy in patients with primary acute angle closure glaucoma under high intraocular pressure is effective, but there still needs further study.
