To evaluate the efficacy and safety of external argon laser choroidotomy for drainage of subretinal fluid (SRF) during scleral buckling procedures for the repair of rhegmatogenous retinal detachments.
Fifty eyes of 50 consecutive patients presenting to a hospital-based retinal outpatient clinic with rhegmatogenous detachments underwent choroidotomy with argon endolaser for SRF drainage. The laser parameters used were 0.5s duration and 0.8W power. The primary outcome measures were successful drainage of SRF and incidence of complications. The drainage was considered successful if it was sufficient to complete the planned scleral buckling procedure. The extent of subretinal haemorrhage was graded.
The mean age of patients was 55 years (range 16-80 years). Successful drainage of SRF was obtained in 47 eyes (94%). The complications observed at the drainage site included subretinal haemorrhage of less than 1 disc diameter in six eyes (12%) and retinal perforation in one eye (2%).
External argon laser choroidotomy appears to be an effective method of draining SRF in rhegmatogenous retinal detachments.
评估在巩膜扣带术治疗孔源性视网膜脱离过程中，使用氩激光脉络膜切开术引流视网膜下液（SRF）的有效性和安全性。
50例连续就诊于某医院视网膜门诊的孔源性视网膜脱离患者的50只眼，接受了氩激光脉络膜切开术以引流SRF。使用的激光参数为持续时间0.5秒、功率0.8瓦。主要观察指标为SRF的成功引流及并发症发生率。如果引流足以完成计划的巩膜扣带术，则认为引流成功。对视网膜下出血的程度进行分级。
患者的平均年龄为55岁（范围16 - 80岁）。47只眼（94%）实现了SRF的成功引流。在引流部位观察到的并发症包括6只眼（12%）出现小于1个视盘直径的视网膜下出血，1只眼（2%）出现视网膜穿孔。
氩激光脉络膜切开术似乎是引流孔源性视网膜脱离中SRF的一种有效方法。
