To compare the rates of intraoperative and postoperative complications of external argon laser choroidotomy and needle drainage techniques during scleral buckle procedures for primary retinal detachment.
A group of 175 patients undergoing scleral buckling for primary retinal detachment was randomly assigned to undergo either external argon laser choroidotomy or needle drainage. Complications associated with drainage of subretinal fluid were categorized as retinal break, retinal incarceration, or hemorrhage (dot, < or = 1 disc diameter [DD], or > 1 DD), and recorded during surgery and 24 hours after surgery.
In the group that underwent laser choroidotomy, 12 (13%) of 92 patients had complications, including 4 dot hemorrhages, 3 hemorrhages 1 DD or smaller, 3 hemorrhages larger than 1 DD, 1 retinal incarceration, and 1 suprachoroidal hemorrhage. In the group that underwent needle drainage, 13 (16%) of 81 patients had complications, including 3 dot hemorrhages, 4 hemorrhages 1 DD or smaller, 5 hemorrhages larger than 1 DD, and 1 suprachoroidal hemorrhage. No significant difference was noted between the two groups in the incidence of complications (P = 0.657).
External argon laser choroidotomy and needle choroidotomy are comparable, safe, and effective ways to drain subretinal fluid during scleral buckle surgery.
比较在巩膜扣带术治疗原发性视网膜脱离过程中，氩激光脉络膜切开术和针吸引流术的术中及术后并发症发生率。
将175例行巩膜扣带术治疗原发性视网膜脱离的患者随机分为两组，分别接受氩激光脉络膜切开术或针吸引流术。视网膜下液引流相关并发症分为视网膜裂孔、视网膜嵌顿或出血（点状，直径≤1个视盘直径[DD]或＞1个DD），并在手术期间及术后24小时记录。
接受激光脉络膜切开术的92例患者中，12例（13%）出现并发症，包括4例点状出血、3例直径≤1 DD的出血、3例直径＞1 DD的出血、1例视网膜嵌顿和1例脉络膜上腔出血。接受针吸引流术的81例患者中，13例（16%）出现并发症，包括3例点状出血、4例直径≤1 DD的出血、5例直径＞1 DD的出血和1例脉络膜上腔出血。两组并发症发生率无显著差异（P = 0.657）。
在巩膜扣带手术中，氩激光脉络膜切开术和针吸脉络膜切开术是引流视网膜下液的可比、安全且有效的方法。
