YAG激光周边虹膜切开术对难治性青光眼治疗后眼内压的影响

Effects of YAG Laser Peripheral Iridotomy on Intraocular Pressure after Refractory Glaucoma Treatment

目的:探究YAG激光周边虹膜切开术对难治性青光眼治疗后眼内压的影响。方法:回顾性分析2016年1月至2017年1月到我院治疗难治性青光眼79例患者治疗资料,研究组(n=40,45眼)行YAG激光周边虹膜切开术,对照组(n=39,43眼)行常规周边虹膜切除术。比较两组患者手术前后眼压,视力、周边前房深度以及前房角,术后并发症发生,手术成功率。结果:两组患者术后眼压均显著降低(P<0.05),且术后研究组明显低于对照组(P<0.05);研究组患者手术后视力变化明显低于对照组患者(P<0.05);术后两组患者周边前房深度和前房角与术前比较均明显改善(P<0.05),术后研究组显著高于对照组(P<0.05);研究组术后并发症发生率(7.5%)低于对照组(15.38%),无显著差异(P>0.05);研究组手术成功率(100%)高于对照组(64.1%),比较差异显著(P<0.05)。结论:YAG激光周边虹膜切开术治疗难治性青光眼降压效果显著,手术成功率高。

Objective:To explore the effects of YAG laser peripheral iridotomy on intraocular pressure after refractory glaucoma treatment.Methods:The treatment data of 79 patients with refractory glaucoma in our hospital from January 2016 to January 2017 were retrospectively analyzed.Study group(n=40,45 eyes)was given YAG laser peripheral iridotomy,and control group(n=39,43 eyes)was given routine peripheral iridotomy.The intraocular pressure,visual acuity,peripheral anterior chamber depth and anterior chamber angle before and after surgery,occurrence of postoperative complications and surgical success rate were compared between the two groups.Results:Postoperative intraocular pressure was significantly decreased in the two groups(P<0.05),and the index after operation in study group was significantly lower than that in control group(P<0.05).The changes of visual acuity in study group after surgery was significantly,lower than that in control group(P<0.05).The anterior chamber depth and anterior chamber angle in the two groups was significantly improved after surgery compared with that before surgery(P<0.05),and the index in study group after surgery was significantly higher than that in control group(P<0.05).The incidence rate of postoperative complications in study group was lower than that in control group(7.5%vs 15.38%)(P>0.05).The surgical success rate in study group was higher than that in control group(100%vs 64.1%)(P<0.05).Conclusions:YAG laser peripheral iridotomy has significant pressure-reduction effects in the treatment of refractory glaucoma,and it has high surgical success rate.
