A technique that uses the El-Mofty/Schepens diathermy tip (MIRA, Inc.) to effect drainage of subretinal fluid during scleral buckling surgery is described. The efficacy of this drainage technique and its complication rate in a series of consecutive patients is discussed.
The study included all of the scleral buckling procedures performed at the Retina Service for retinal detachments in which this technique was used. The El-Mofty/Schepens diathermy tip was first used to cauterize the choroid at the drainage site at low power, thus rendering it avascular, and then at higher power, to cause vaporization of the choroid, and allow spontaneous drainage of subretinal fluid. The success rate and all intraoperative and postoperative complications were recorded.
This technique achieved successful spontaneous drainage in 53 (82.8%) of 64 consecutive cases. Complications that are occasionally associated with the drainage of subretinal fluid, including iatrogenic retinal holes, choroidal hemorrhage, and retinal incarceration in the sclerotomy site, were not seen in any of the cases.
This method provides a simple and safe technique for the drainage of subretinal fluid that obviates the need to directly perforate the choroid.
描述一种在巩膜扣带手术中使用埃尔 - 莫夫蒂/谢彭斯透热电极（MIRA公司）进行视网膜下液引流的技术。讨论该引流技术在一系列连续患者中的疗效及其并发症发生率。
该研究纳入了视网膜科针对视网膜脱离进行的所有巩膜扣带手术中使用此技术的病例。首先使用埃尔 - 莫夫蒂/谢彭斯透热电极以低功率烧灼引流部位的脉络膜，使其无血管，然后以较高功率使脉络膜汽化，从而使视网膜下液自发引流。记录成功率以及所有术中及术后并发症。
该技术在连续64例病例中的53例（82.8%）实现了成功的自发引流。在任何病例中均未出现偶尔与视网膜下液引流相关的并发症，包括医源性视网膜裂孔、脉络膜出血和巩膜切开部位的视网膜嵌顿。
该方法为视网膜下液引流提供了一种简单且安全的技术，无需直接穿透脉络膜。
