To compare the outcome of transscleral cyclophotocoagulation (TSCPC) using a diode laser with that of TSCPC using an Nd:YAG laser in neovascular glaucoma.
The surgical outcome of diode laser TSCPC was retrospectively compared with that of free-running mode Nd:YAG laser (FR-YAG) TSCPC and continuous-wave mode Nd:YAG laser (CW-YAG) TSCPC. Twenty-one eyes of 21 patients in the diode laser group, 9 eyes of 9 patients in the FR-YAG group, and 9 eyes of 9 patients in the CW-YAG group were treated.
The Kaplan-Meier life-table analysis revealed that the probability (mean +/- standard error) of successful intraocular pressure control with diode laser TSCPC at 3 years postoperatively was 47.2 +/- 12.6% per operation and 55.9 +/- 16.3% per eye. Compared with the CW-YAG TSCPC, the diode laser TSCPC had a significantly higher probability of success throughout the follow-up period. Diode laser TSCPC was associated with improvements or preservation of visual acuity in 16 of 21 eyes (76%), and was the best of the three laser sources. Postoperative complications were minor following diode laser TSCPC.
Diode laser TSCPC appears to be as effective as FR-YAG TSCPC and better than CW-YAG TSCPC for treating neovascular glaucoma.
比较二极管激光经巩膜睫状体光凝术（TSCPC）与钕:钇铝石榴石激光经巩膜睫状体光凝术治疗新生血管性青光眼的效果。
回顾性比较二极管激光TSCPC与自由运行模式钕:钇铝石榴石激光（FR-YAG）TSCPC及连续波模式钕:钇铝石榴石激光（CW-YAG）TSCPC的手术效果。二极管激光组21例患者的21只眼、FR-YAG组9例患者的9只眼及CW-YAG组9例患者的9只眼接受了治疗。
Kaplan-Meier生存表分析显示，二极管激光TSCPC术后3年眼压控制成功的概率（均值±标准误）为每次手术47.2±12.6%，每只眼55.9±16.3%。与CW-YAG TSCPC相比，二极管激光TSCPC在整个随访期内成功概率显著更高。二极管激光TSCPC使21只眼中的16只（76%）视力得到改善或保持，是三种激光源中效果最好的。二极管激光TSCPC术后并发症轻微。
二极管激光TSCPC在治疗新生血管性青光眼方面似乎与FR-YAG TSCPC效果相当，且优于CW-YAG TSCPC。
