激光周边虹膜成形术治疗残余性青光眼

目的评价倍频Nd:YAG激光行激光周边虹膜成形术治疗残余性青光眼的有效性。方法 20例22眼残余性青光眼,使用倍频Nd:YAG激光行激光周边虹膜成形术,观察术后眼压、视力、杯盘比、前房深度、房角角度等指标变化情况。结果术后1个月、3个月、6个月眼压分别为(18.48±1.60)mmHg(1kPa=7.5mmHg)、(18.72±1.40)mmHg、(19.21±1.49)mmHg,与术前相比,差异均有统计学意义(均为P<0.05);术后6个月时杯盘比为0.59±0.22,与术前相比,差异无统计学意义(P>0.05);术后6个月时前房深度为(1.72±0.22)mm,与术前相比,差异无统计学意义(P>0.05);术后6个月时房角角度为(21.41±2.74)°,与术前相比,差异有统计学意义(P<0.05)。结论倍频Nd:YAG激光行激光周边虹膜成形术能有效降低残余性青光眼患者的眼压,手术简单易行,值得临床推广。

Clinical effect of laser peripheral iridoplasty for remnant glaucoma

Objective To evaluate the efficacy of laser peripheral iridoplasty(LPIP)by double-frequency Nd:YAG laser for the remnant glaucoma.Methods Twenty-two eyes of 20 patients were treated with LPIP by double-frequency Nd:YAG laser,and postoperative intraocular pressure,visual acuity,C/D value,anterior chamber depth and angle of anterior chamber were observed.Results The intraocular pressure at postoperative 1 month,3 months and 6 months were (18.48±1.60)mmHg(1 kPa=7.5 mmHg),(18.72±1.40)mmHg and (19.21±1.49)mmHg;Compared with pre-operation,there were statistical differences(all P<0.05).C/D value at postoperative 6 months was 0.59±0.22,there was no statistical difference compared with pre-operation(P>0.05).The anterior chamber depth at postoperative 6 months was (1.72±0.22)mm,there was no statistical difference compared with pre-operation(P>0.05).The angle of anterior chamber at postoperative 6 months was (21.41±2.74)°,there was statistical difference compared with pre-operation(P<0.05).Conclusion LPIP by double-frequency Nd:YAG laser is a safe and effective method for the remnant glaucoma,it’s to be worthy of spreading.
