摘　　要：目的观察分析慢性原发性闭角型青光眼(chronic primary angle-closure glaucoma,CPACG)患者超声乳化白内障摘出术后眼前节参数变化。方法选择我院2008年1月至2011年6月行超声乳化白内障摘出术的CPACG患者45例(45眼),术前1 d、术后3个月采用Pencatam眼前节分析仪测量患者中央前房深度、周边前房深度、前房容积、500μm房角开放距离、500μm小梁网虹膜间隙面积,利用OCT检查各象限前房角,观察记录术前1 d及术后1 d、7 d、30 d患者裸眼视力,同时测量术前1d及术后7 d患者眼压。结果术前中央前房深度、周边前房深度、前房容积、500μm房角开放距离、500μm小梁网虹膜间隙面积分别为(1.82±0.18)mm、(0.78±0.15)mm、(89.28±25.62)mm3、(0.25±0.14)mm、(0.15±0.06)mm2,术后分别为(3.42±0.26)mm、(1.84±0.21)mm、(138.44±18.78)mm3、(0.64±0.28)mm、(0.28±0.13)mm2,差异均有统计学意义(均为P<0.05)。术后各象限前房角均增宽,差异均有统计学意义(均为P<0.05)。与术前相比,术后1 d、7 d、30 d患者裸眼视力均明显改善,差异均有统计学意义(均为P<0.05)。术后7 d与术前患者眼压比较,差异有显著统计学意义(P<0.01)。结论超声乳化白内障摘出术可有效改善CPACG患者眼前节结构,有效控制眼压,改善患者视力。Objective To observe the anterior segment changes after phacoemulsitication for chronic primary angle-closure glaucoma （CPACG）. Methods Forty-five patients（45 eyes） with CPACG in our hospital from January 2008 to June 2011 were chosen and received phacoemulsification. The central anterior chamber depth, peripheral anterior chamber depth, anterior chamber volume, angle opening distance at distance of 500 μm from scleral spur and trabecular iris space area at distance of 500 μm from scleral spur were detected by Pencatam at preoperative 1 day and postoperative 3 months, the anterior chamber angle was observed by OCT, the uncorrected visual acuity at preoperative 1 day and postoperative 1 day, 7 days and 30 days were examined, and the intraocular pressure at preoperative 1 day and postoperative 7 days was also examined. Results The preoperative central anterior chamber depth, peripheral anterior chamber depth, anterior chamber volume, angle opening distance at distance of 500 μm from scleral spur and trabecular iris space area at distance of 500μm from scleral spur were（ 1.82 ±0.18 ） mm, （ 0.78 ± 0. 15 ） mm, （ 89.28 ±25.52 ）mm3, （ 0.25 ± 0.14）mm, （0.15 ±0.05） mm2,the postoperative were（3.42 ±0.25）mm, （1.84 ± 0.21）mm, （138.44 ± 18.78）mm3, （0.54 ± 0.28 ） inm, （0.28 ± 0.13 ）mm2, there were statistical differences （ all P 〈 0.05 ）. The postoperative anterior chamber angles at each quadrant were widened（ all P 〈0.05）. The uncorrected visual acuity at postoperative 1 day,7 days and 30 days all improved,there were statistical differences compared with preoperation（ all P 〈 0.05 ）. There was significant difference in intraocuiar pressure between preoperation and postoperative 7 days （P 〈 0.01 ）. Conclusion Phacoemulsification can improve the anterior segment structure of CPACG, effectively control the intraocular pressure and increase the visual acuity.
