AIMS
This study was designed to compare suture needle drainage (SND) with argon laser drainage (ALD) of subretinal fluid.
METHODS
A prospective, randomised, controlled, clinical trial was carried out on 93 patients undergoing external drainage of subretinal fluid during scleral buckling surgery for rhegmatogenous retinal detachment. The incidence of successful drainage, incidence of subretinal haemorrhage, incidence of retinal incarceration, and incidence of retinal perforation were determined.
RESULTS
The success rate was 97.9% in the ALD group and 84.8% in the SND group (difference-13.1%, 95% CI-26.4% to 2.0%). The incidence of clinically significant subretinal haemorrhage was 4.3% in the ALD group compared with 28.3% in the SND group (difference 24.0%, 95% CI 7.6% to 40.4%). The incidence of incarceration was comparable in each group. There were no cases of retinal perforation.
CONCLUSIONS
The use of ALD was associated with a higher rate of successful SRF drainage, and a lower incidence of clinically significant subretinal haemorrhage than SND. ALD is preferred when an endolaser is available.
目的
本研究旨在比较视网膜下液的缝线针引流（SND）与氩激光引流（ALD）。
方法
对93例因孔源性视网膜脱离行巩膜扣带手术时进行视网膜下液外引流的患者进行了一项前瞻性、随机、对照临床试验。确定了成功引流的发生率、视网膜下出血的发生率、视网膜嵌顿的发生率和视网膜穿孔的发生率。
结果
ALD组成功率为97.9%，SND组为84.8%（差异-13.1%，95%CI-26.4%至2.0%）。ALD组临床上显著的视网膜下出血发生率为4.3%，而SND组为28.3%（差异24.0%，95%CI 7.6%至40.4%）。每组的嵌顿发生率相当。无视网膜穿孔病例。
结论
与SND相比，使用ALD可提高视网膜下液成功引流率，并降低临床上显著的视网膜下出血发生率。当有眼内激光设备时，首选ALD。
