不同能量氩离子激光照射防止翼状胬肉术后复发的研究

Different-energy Argon Laser in Prevention of Postoperative Recurrence of Pterygium:a Clinical Research

目的探讨不同能量氩离子激光防止翼状胬肉术后复发的效果。方法将116例116只眼原发性翼状胬肉术后1周手术区结膜或角膜缘出现新生血管胚芽的患者分为3组:(1)低能量氩离子激光光凝组(A组)56例,功率0.1～0.15W;(2)常规能量氩离子激光光凝组(B组)30例,功率0.2～0.3W;(3)对照组(C组)30例,不行光凝。结果随访1年,A、B、C组胬肉术后复发率分别为7.1%、10.0%、33.3%。激光治疗后A组患者结膜充血、结膜灼伤、结膜充血的发生率均低于B组(P<0.05)。结论低能量氩离子激光照射封闭胬肉术后1周新生血管胚芽,为防止翼状胬肉术后复发的一种有效方法,激光治疗后胬肉早期新生血管胚芽、结膜灼伤、结膜出血等局部反应较少。

Objective To explore the effect of diffrent-energy argon laser on preventing the postoperative recurrence of pterygium. Methods A total of 116 cases（ 116 eyes） with new vessels appearing in surgery site of cornea and/or conjunctivae one week after undergoing pterygium excision were divided into 3 groups： group A（56 cases,56 eyes） received low-energy argon laser photaeoagulation, power： 0. 1-0. 15 W; group B （30 cases, 30 eyes） received normal-energy argon laser photocoagulation, power 0. 2-0. 3 W;group C （30 cases,30 eyes） didnt receive any argon laser photocoagulation. Results After one year follow-up, the rate of postoperative recurrence of. three groups was 7. 1%, 10.0% and 33. 3%, respectively. As compared with group C, the rate of postoperative recurrence of groups A and B was significantly decreased （ P 〈 0. 05 and 〈 0. 01, respectively）. As compared with group B, the rate of postoperative recurrence of group A was not significantly changed （P 〉 0. 05） ; but the complications of conjunctive burn and hemorrhage in group A were significantly decreased（ P 〈 0.05）. Conclusions Using argon laser to coagulate new vessels can reduce the postoperative recurrence rate the of ptcrygium. And low-energy argon laser can reduce the complications of photocoagulation, it＇s an effective and safe treatment in preventing the postoperative recurrence of pterygium.
