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 rabbils eyes.
