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(primary angle-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。

[Abstract]
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.
