目的：观察白内障超声乳化术中高灌注压对急性闭角型青光眼(acute angle-closure glaucoma，AACG)患者术后视功能的影响。

方法：选择2017-03/2018-10于我院住院并行白内障超声乳化摘除人工晶状体植入联合房角分离的AACG合并白内障的患者35例37眼，比较术前、术后3、 6mo最佳矫正视力(BCVA)、眼压、平均视敏度(MS)、平均缺损(MD)和丢失方差平方根(sLV)值的变化。

结果：与术前相比，患者术后3、6mo BCVA、 MS明显改善，MD和sLV明显下降，眼压显著降低(P<0.001)，术后3、6mo组间比较无差异(P>0.05)。

结论： 白内障超声乳化术中高灌注压不会对AACG患者术后视功能造成损伤。

METHODS: Totally 35 patients(37 eyes)with AACG with cataract were included to do the surgery of phacoemulsification with goniosynechialysis. They have been followed up for 6mo. The preoperative and postoperative(3mo and 6mo)best corrected visual acuity(BCVA), intraocular pressure, mean sensitivity(MS), mean defect(MD), and square root loss variance(sLV)were measured and compared.

RESULTS: Compared with preoperative results, 3mo and 6mo BCVA were significantly improved and intraocular pressure was significantly reduced after operation, with statistically significant differences(P<0.001). There was no statistically significant difference between groups after operation(P>0.05). After surgery, 3mo and 6mo MS increased significantly, MD and sLV decreased significantly, and the difference was statistically significant(P<0.001). There was no statistically significant difference between the groups after surgery(P>0.05).

CONCLUSION: The high perfusion irrigation during phacoemulsification does not damage the visual function of patients with AACG.
