摘要: 目的:探讨利用Nd∶YAG激光提高视网膜-脉络膜静脉吻合术的成功率。方法:灰色家兔20只(40只眼)用氩激光建立视网膜分支静脉阻塞(BRVO)模型,模型成功家兔随机分为实验组10只(20只眼),用氩激光随后用Nd∶YAG激光;对照组10只(20只眼),单独用氩激光诱发形成视网膜和脉络膜静脉间的吻合。结果:通过眼底荧光血管造影(FFA)检查和彩色眼底照像,实验组6只眼成功建立视网膜脉络膜吻合,检眼镜下激 光击射部位静脉中断呈漏斗状陷入脉络膜;FFA显示远端及近端静脉内血流汇入吻合处,吻合形成时间为4~6周,对照组未形成吻合。观察2~6个月由激光击射引起的视网膜或玻璃体出血均在8周内吸收,未见其他严重并发症。结论:用Nd∶YAG激光可提高诱导视网膜脉络膜静脉吻合的成功率。

Abstract: Objective To improve the efficacy of the Nd∶YAG laser-induced chorioretinal venous anastomosis in the rabbits′eyes. Methods Immediately after branch retinal vein occlusion(BRVO) model was made by argon laser in 40 eyes of 20 normal rabbits, the rabbits were divided into two groups. In the first group (experimental group),there were 10 rabbits treated with the argon laser followed by the Nd∶YAG laser induced chorioretinal venous anastomosis. In the second group(control group),the rabbits were treated only with the argon laser induced chorioretinal venous anastomosis. Results An anastomosis in experimental group was formed in 6 rabbits within 4-6 weeks after treatment while no anastomosis was formed in control group. During 2-6 months the hemorrhage of retina or vitrous with laser photocoagulation were absorbed within 8 weeks and no other severe complications were found. Conclusion Applying Nd∶YAG laser can improve the efficacy of chorioretinal venous anastomosis in the rabbits′eyes.
