Objective To observe the effect of pre - photocoagulation iris by krypton laser in glaucoma laser treatment. Methods All 78 cases( 92 eyes )were grouped into A and B. Group A was treated by krypton laser peripheral iridoplasty( LPIP ), iris pre - photocoagulation and YAG laser peripheral iridectomy ( LPI ). Group B was only treated by LPIP and YAG LPI. After laser Treatment, IOP, visual acuity and iris haemorrhage were observed. Results The difference of IOP and iris haemorrhage between group A and group B was statistically significant( P ＜ 0.05 ). Conclusion The method of pre - thermocoagulation iris by krypton laser can reduce the complication of glaucoma laser treatment effectively.%目的 观察虹膜切口氪激光预光凝对青光眼激光治疗的影响.方法 将我院门诊需行激光治疗的青光眼患者78例(92只眼)随机分成A、B组.A组行虹膜氪激光周边成形+切口周围预光凝+YAG激光切开术.B组行虹膜氪激光周边成形+YAG激光切开术,治疗后观察两组的视力、眼压、虹膜出血等指标.结果 比较两组在治疗后眼压和虹膜出血等并发症情况的差异有统计学意义(P < 0.05).结论 氪激光虹膜切口预光凝可以有效地降低青光眼激光治疗后的并发症.
