与电凝术相比，冷冻术对巩膜影响甚小，但可导致术后黄斑囊样水肿，视网膜色素上皮细胞游离，破坏血-视网膜屏障，刺激增殖性玻璃体视网膜病变的发生，而后者是视网膜脱离复位术失败的主要原因[1，2 ] 。

Methods Immediately after branch retinal vein occlusion model was made by argon laser in 40 eyes of 20 normal rabbits, the rabbits were divided into two groups. In the first group,there were 10 rabbits treated with the argon laser followed by the Nd∶YAG laser induced chorioretinal venous anastomosis.

灰色家兔20只（40只眼）用氩激光建立视网膜分支静脉阻塞模型，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。

Althought this surgery has been reported by a few doctors recently, the safety and effectiveness need to be evaluated in further studies. In our study, the approach of the chorioretinal venous anatomosis in the model eyes with branch retinal vein occlusion, are induced by different surgical anastomosis procedures, in order to invest the effectiveness and safety and make a pilot clinic treatment exploration. Methods and materials The study was divided two ports: animal experiment and clinical study.

这种治疗方法的可行性和疗效评价，在激光诱导脉络膜视网膜静脉吻合术治疗非缺血型CRVO病人中得到证实；而对缺血型CRVO，由于病情严重，晚期新生血管并发症产生的危险性高，或者已有产生，因此最近开展的用玻璃体切除联合手术吻合脉络膜视网膜静脉的外科治疗作为最新的探索性治疗方法，在国外已见少数病例报告，但是尚需要进一步的研究观察来评价其可行性、安全性和疗效。

In our study, the approach of the chorioretinal venous anatomosis in the model eyes with branch retinal vein occlusion, are induced by different surgical anastomosis procedures, in order to invest the effectiveness and safety and make a pilot clinic treatment exploration.

对照组：用眼内电凝方法建立兔眼的视网膜分枝静脉阻塞模型：单纯穿刺吻合组：在建模完成后，用200针直接穿刺切开距阻塞点以远2/3一IPD的淤滞状态静脉管壁和其下方的视网膜和Bruch's膜；吻合联合不吸收材料植入组：在同Ta组选定的吻合部位，用MVR刀切开视网膜和Bruch's膜和静脉管壁，在视网膜切口植入一小段7一0 prolene不吸收缝线。

There is presently no effective treatment available.in recent years,people highlight on reinfusing the affected vein,chorioretinal venous anastomosis allows obstructed venous blood to exit the retinal circulation via the choroid,thus bypassing the site of occlusion,so to recover retinal perfusion lessening complications.

近年来，越来越多的学者致力于恢复患眼视网膜静脉回流的研究，如通过脉络膜视网膜静脉吻合以尽快解除静脉阻塞，恢复视网膜灌注，从而提高视力，减少并发症的发生。

Vascular injury included pain reaction to the infusion, vascular wall injury, circumvascular tissue with stasis of blood, and vascular occlusion.
