PURPOSE
To compare the efficacy of transscleral cyclophotocoagulation using a neodymium: YAG (Nd:YAG) or semiconductor diode laser in controlling intraocular pressure in patients with refractory glaucoma.
METHODS
In a prospective study, 95 eyes of 91 patients with refractory glaucoma randomly received Nd:YAG or diode cyclophotocoagulation. Patients were followed for a mean of 10.4 months (10.42 +/- 3.16, mean +/- SD). We compared available data preoperatively and at 1 week, 1 month, 6 months, and 12 months postoperatively. Data analyzed were corrected visual acuity, intraocular pressure, and the type of glaucoma.
RESULTS
There was a statistically significant decrease in intraocular pressure after both Nd:YAG and diode cyclophotocoagulation at each time period. However, there were no significant differences in postoperative intraocular pressure or visual acuity change between Nd:YAG and diode procedures.
CONCLUSIONS
Compared with the Nd:YAG laser for transscleral cyclophotocoagulation, the diode laser has technological advantages including portability, durability, and smaller size, while providing equivalent postoperative intraocular pressure and visual acuity change.
目的
比较钕：钇铝石榴石（Nd：YAG）激光或半导体二极管激光经巩膜睫状体光凝术控制难治性青光眼患者眼压的疗效。
方法
在一项前瞻性研究中，91例难治性青光眼患者的95只眼随机接受Nd：YAG或二极管睫状体光凝术。患者平均随访10.4个月（10.42±3.16，平均值±标准差）。我们比较了术前以及术后1周、1个月、6个月和12个月的可用数据。分析的数据包括矫正视力、眼压和青光眼类型。
结果
Nd：YAG和二极管睫状体光凝术后各时间段眼压均有统计学意义的下降。然而，Nd：YAG和二极管手术术后眼压或视力变化无显著差异。
结论
与Nd：YAG激光经巩膜睫状体光凝术相比，二极管激光具有便携、耐用和体积小等技术优势，同时术后眼压和视力变化相当。
