选择性激光小梁成形术对高眼压症的临床疗效观察

Effect of selective laser trabeculoplasty on ocular hypertension

目的:评价选择性激光小梁成形术(selective laser trabeculoplasty,SLT)治疗高眼压症(ocular hypertention,OH)的治疗效果。方法:诊断为OH患者28例(28眼,男15例,女13例),平均年龄31.4±11.0岁;术前眼压29.11±4.94mmHg。所有患者上方房角180°范围内进行治疗,能量0.85～1.56mJ,点数80～120点。测量术后1,2,3,4h眼压,术后1d;1wk;1,3,6mo;1a随访,监测术后眼压、视力、视野、杯盘比变化。结果:患者术前平均眼压29.33±4.17mmHg,术后1d为18.73±5.70mmHg、于术后1d停用药物治疗,其后随访的眼压结果:1wk为22.39±4.36mmHg,1mo为20.92±3.74mmHg,3mo为23.05±3.06mmHg,6mo为23.54±3.12mmHg,1a为24.68±2.57mmHg。术前患者杯盘比为0.50±0.19,术后1a为0.51±0.17;术前视力0.82±0.30,术后1a视力0.84±0.43;视野术后无变化。结论:SLT可以有效的降低高眼压症患者的眼内压。

AIM： To evaluate the clinical effect of treating ocular hypertention （OH） through selective laser trabeculoplasty （SET）. METHODS： Among 28 eyes diagnosed as OH were treated with a frequency-doubled, Q-switched Nd： YAG laser （532nm）. A total of approximately 80-120 nonoverlapping spots were placed over 180 of the TM at the energy levels range from 0. 85-1. 56m J/ pulses. Every patient was asked for follow-up at 1 hour, 2 hours, 3 hours, 4 hours; 1 day; 1 week; 1 month, 3 months, 6 months, 1 year after treatment. Intraocular pressure （IOP）, visual acuity, C/D and visual field were examined every time. RESULTS： The pretreatment lOP was 29.33 ± 4.17mmHg. After the end of 1 month of follow-up the lOP was 20.92 ± 3.74mmHg, after the end of 3 months of follow-up the lOP was 23. 05 ± 3. 06mmHg, after the end of 6 months of follow-up the lOP was 23.54 ± 3.12mmHg, after the end of 1 year of follow-up the lOP was 24. 68 ± 2. 57mmHg, without significant differences in visual acuity, visual field, and C/D. CONCLUSION, SLT is a kind of effective treatment method of OH.
