To investigate the efficacy and safety of selective laser trabeculoplasty (SLT) in the treatment of primary open angle glaucoma (POAG).
In a prospective non-randomized clinical study, 63 patients (85 eyes) with POAG and medically uncontrolled intraocular pressure (IOP) underwent SLT. A total of 50 +/- 5 adjacent but nonoverlapping spots were placed over inferior 180 degrees of the trabecular meshwork using a 532 nm, Q-switched, Nd: YAG laser at energy levels ranging from 0.6 - 1.8 mJ per pulse. After SLT, the eyes continued to receive the identical drug regimen. All patients were observed before and 1, 2 hours, 1, 7 and 14 days, and 1, 2, 3, 6, 9, 12, 18, and 24 months after the treatment.
The average pre-operative IOP was (25 +/- 4) mm Hg (1 mm Hg = 0.133 kPa). The mean IOP reduction from baseline were 8.1 mm Hg (32.0%) 1 day after the SLT, 5.6 mm Hg (22.1%) 7 days after the SLT, 4.7 mm Hg (18.6%) 14 days after the SLT, 5.5 mm Hg (21.7%) 1 month after the SLT, 5.1 mm Hg (20.2%) 2 months after the SLT, 5.9 mm Hg (23.3%) 3 months after the SLT, 5.2 mm Hg (20.6%) 6 months after the SLT, 4.0 mm Hg (15.8%) 9 months after the SLT, 4.2 mm Hg (16.6%) 12 months after the SLT, 3.8 mm Hg (15.0%) 18 months after the SLT, and 3.3 mm Hg (13.0%) 24 months after the SLT (P < 0.01 or 0.05). Adverse reactions were minimal, including conjunctival injection, mild anterior chamber reaction, and transient pressure spike.
SLT is a safe, and effective method of reducing IOP in POAG patients.
探讨选择性激光小梁成形术(SLT)治疗原发性开角型青光眼(POAG)的疗效和安全性。
在一项前瞻性非随机临床研究中,63例(85只眼)POAG且眼压经药物治疗控制不佳的患者接受了SLT。使用532nm调Q钕:钇铝石榴石激光,在小梁网下方180度范围内共放置50±5个相邻但不重叠的光斑,每个脉冲能量水平为0.6 - 1.8mJ。SLT术后,这些眼睛继续接受相同的药物治疗方案。所有患者在治疗前、治疗后1、2小时、1、7和14天以及1、2、3、6、9、12、18和24个月进行观察。
术前平均眼压为(25±4)mmHg(1mmHg = 0.133kPa)。SLT术后1天眼压较基线平均降低8.1mmHg(32.0%),术后7天降低5.6mmHg(22.1%),术后14天降低4.7mmHg(18.6%),术后1个月降低5.5mmHg(21.7%),术后2个月降低5.1mmHg(20.2%),术后3个月降低5.9mmHg(23.3%),术后6个月降低5.2mmHg(20.6%),术后9个月降低4.0mmHg(15.8%),术后12个月降低4.2mmHg(16.6%),术后18个月降低3.8mmHg(15.0%),术后24个月降低3.3mmHg(13.0%)(P < 0.01或0.05)。不良反应轻微,包括结膜充血、轻度前房反应和短暂的眼压峰值。
SLT是降低POAG患者眼压的一种安全有效的方法。
