激光周边虹膜成形术治疗急性发作的PACG

Double frequency 532 laser peripheral iridoplasty in treatment of acute attack of primary angle-closure glaucoma

目的:探讨倍频532激光周边虹膜成形术在患者不适合用抗青光眼药物的情况下,治疗急性发作期原发性闭角型青光眼(primaryangle-closure glaucoma,PACG)的安全性及有效性。方法:患者13例13眼应用4g/L盐酸奥布卡因滴眼液表面麻醉后立即行倍频532nm激光周边虹膜成形术。术前及术后15,30,60min测量眼压。结果:患者眼压:虹膜成形术前平均60.6±8.8mmHg(1kPa=7.5mmHg),术后15min下降至平均37.4±7.3mmHg,术后30min平均26.2±6.6mmHg,术后60min平均17.1±5.3mmHg。所有患眼角膜水肿全部消退,无严重并发症出现。结论:倍频532激光周边虹膜成形术治疗急性发作期PACG安全、有效,可作为治疗首选。

AIM： To explore the safety and effectiveness of double frequency 532 laser peripheral iridoplasty （LPI） in treatment of acute attack of primary angle-closure glaucoma（PACG） which isn＇t suitable for drugs.METHODS： Thirteen consecutive patients with acute PACG were recruited into the study. Each patient received oxybuprocaine（4g/L）, and double frequency 532 LPI immediately. The intraocular pressures （IOP） of 15 minutes, 30 minutes and 60 minutes after double frequency 532 LPI were documented.RESULTS： The mean IOP of this group of patients was reduced from 60.6 ±8.8mmHg （1kPa=7.5mmHg）, before double frequency 532 LPI to 37.4 ±7.3mmHg in 15 minutes, 26.2±6.6mmHg in 30 minutes, and 17.1±5.3mmHg in 60 minutes after LPI. The cornea edema patients cleared up, no serious complications.CONCLUSION： Double frequency 532 LPI in the treatment of PACG is safe, effective, and can be used for treatment of first choice.
