目的研究选择性激光小梁成形术(SLT)治疗原发开角型青光眼(POAG)的疗效及安全性。设计回顾性病例研究,研究对象为10例20眼双眼开角型青光眼患者。方法对年龄≥30岁POAG患者应用Q开关,倍频532nm,YAG激光器行SLT治疗。范围360房角,共100个激光脉冲,单脉冲能量:0.5-1.4mj,激光手术前后抗青光眼药物选择保持不变,随访6个月,激光治疗后1h、1d、2周、4周、3个月、6个月进行随访。主要指标为眼压及并发症。结果患者SLT术前基线眼压为(25.7±2)mmHg。术后1d、2周、4周、3个月、6个月眼压均下降,SLT治疗早期原发性开角型青光眼随访半年是安全、有效的。结论 SLT具有安全、有效、无损伤、操作简便等特点,可以作为治疗POAG的有效方法。
Objective To study the efficacy and safety of selective laser trabeculoplasty (SLT) in the treatment of primary open angle glaucoma (POAG). A retrospective case study was designed and studied in 10 patients with 20 eyes with open-angle glaucoma. Methods The Q-switch, double-frequency 532nm and YAG laser were used to treat patients with POAG ≥30 years old. Range 360 room angle, a total of 100 laser pulses, single pulse energy: 0.5-1.4mj, before and after laser surgery anti-glaucoma drug choice remains unchanged for 6 months after laser treatment 1h, 1d, 2 weeks, 4 weeks, 3 Months, 6 months follow-up. The main indicators for intraocular pressure and complications. Results The baseline IOP before SLT was (25.7 ± 2) mmHg. Intraocular pressure decreased at 1, 2, 4, 3 and 6 months postoperatively. It is safe and effective to treat primary open angle glaucoma in the early stage of SLT for six months. Conclusion SLT is safe, effective, non-destructive, easy to operate and so on, which can be used as an effective method to treat POAG.
