Abstract

Purpose: 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.

Methods: 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.

Results: 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%).

Conclusion: External argon laser choroidotomy appears to be an effective method of draining SRF in rhegmatogenous retinal detachments.

体外氩激光脉络膜切开术引流视网膜下积液。

目的:评价体外氩激光脉络膜切开术在巩膜屈曲术中引流视网膜下液(SRF)的疗效和安全性。方法:对50例连续到医院视网膜门诊就诊的孔源性脱离患者进行脉络膜切开氩激光引流术。激光参数为持续时间0.5s，功率0.8W。主要观察指标为SRF引流成功及并发症发生率。如果引流足够完成计划的巩膜扣合手术，则认为引流成功。视网膜下出血程度分级。结果:患者平均年龄55岁(16 ~ 80岁)。47眼(94%)成功引流SRF。引流部位并发症包括6眼(12%)视网膜下出血小于1椎间盘直径，1眼(2%)视网膜穿孔。结论:体外氩激光脉络膜切开术是引流孔源性视网膜脱离的有效方法。
