目的研究选择性激光小梁成形术(SLT)治疗原发性开角型青光眼的安全性和有效性。设计回顾性病例系列。研究对象47例62眼早期原发性开角性青光眼患者。方法所有患者应用Q开关、倍频532 nm、Nd:YAG激光器(Selecta Duet型)行SLT治疗,范围下方房角180度,50个点,单脉冲能量0．5～1．4mJ。激光手术前后抗青光眼药物保持不变。随访12个月。主要指标眼压与并发症。结果在62眼中有72．5%眼压控制。SLT术前平均眼压(24．3±3．7)mmHg,手术后12个月的平均眼压(19．1±3．9)mmHg,眼压的下降差异有统计学意义(P＜0．001)。所有病例在手术后1小时均出现轻度前房炎症反应,3天后消失。结论SLT治疗早期原发性开角型青光眼随访一年是安全有效的。(眼科,2007,16:37-39)
Objective To study the safety and efficacy of selective laser trabeculoplasty (SLT) in the treatment of primary open-angle glaucoma. Design retrospective case series. Forty-two patients (62 eyes) with primary open-angle glaucoma were studied. Methods All patients underwent SLT with frequency doubling 532 nm and frequency doubling 532 nm. The SLA was performed with a Nd: YAG laser (Selecta Duet type). The angle of the anterior chamber was 180 degrees at 50 points and the pulse energy was 0.5-1.4 mJ. Anti-glaucoma medications remained unchanged before and after laser surgery. Follow up for 12 months. The main indicators of intraocular pressure and complications. The result was 72.5% IOP control in 62 eyes. The mean intraocular pressure (IOP) before SLT was (24.3 ± 3.7) mmHg, the mean IOP at 12 months after operation was (19.1 ± 3.9) mmHg, and the intraocular pressure was significantly decreased .001). All cases of mild inflammation of the anterior chamber appeared 1 hour after surgery and disappeared after 3 days. Conclusion SLT is safe and effective in the treatment of early primary open-angle glaucoma for one year. (Ophthalmology, 2007,16: 37-39)
