氩激光小梁成形术治疗残余性青光眼

Argon laser trabeculoplasty for remnant glaucoma

目的评价氩激光小梁成形术治疗残余性青光眼患者的有效性。方法16例20眼残余性青光眼患者,用氩激光照射小梁网非色素性与色素性小梁交界处。光斑直径50μm,脉宽0.1s,功率0.6-1.0W,光凝点数50-60。术前15min、术后滴5g·L-1噻吗洛尔滴眼液控制一过性高眼压。结果术前、术后1个月、3个月、6个月平均眼压分别为（27.66±2.20）mmHg（1kPa=7.5mmHg）、（17.9±3.9）mm-Hg、（19.6±4.7）mmHg、（20.1±4.7）mmHg。术后一过性高眼压发生率20%.结论氩激光小梁成形术能有效地降低残余性青光眼患者的眼压。

Objective To evaluate the efficacy of argon laser trabecudoplasty （ALT） for the remnant glaucoma. Methods Twenty eyes of 16 patients were treated with argon laser. The laser was applied to the junction of anterior and posterior pigment trabecular meshwork from 50 spots to 60 spots. The setting was 50 μm spot size,0.1 second duration and 0.6 W to 1.0 W power. One drop of 5 g · L^-1 timolol was given 15 minutes before and right after ALT to control the intraocular pressure （IOP） spikes. The follow-up time was 6 months. Results The mean IOP at baseline, 1 month,3 months,6 months were （27.66 ± 2.2 ） mmHg （1 kPa =7.5 mmHg）,（ 17.9 ± 3.9）mmHg, （19.6 ± 4.7） mmHg and （ 20.1 ± 4.7 ） mmHg, respectively. The incidence rate of transient IOP spike was 20%. Conclusion The ALT appears to be a safe and effective method to lower IOP in patients with the remnant glaucoma.
