Abstract:
Purpose To evaluate the therapeutic effect of laser-induced chorioretinal venous anastomosis for retinal vein occlusion (RVO)． Methods The investigation included 28 consecutive patients (28 eyes) with RVO．The non-ischemic group 18 cases (18 eyes) were treated with the krypton red laser to induce chorioretinal venous anastomosis， the ischemic group underwent the same therapy and the grid or scatter-type photocoagulation at the same time． All of the eyes were followed up for more than 5 months， and with an average period of 6．6 months． Results Seven cases (7 eyes， 38．9%) of the non-ischemic group created successful chorioretinal venous anastomosis， with mean improvement of 4．43±0．78 standard deviation （±s） lines of best-corrected visual acuity compared to 0．19±0．67 （±s） lines for 11 eyes with unsuccessful anastomosis (P<0．001)． None of the seven eyes developed to ischemic state． Four of the 11 eyes with unsuccessful anastomosis converted to ischemic type (36．4%)． Two cases of the ischemic group created successful anastomosis with improvement in visual acuity． The other cases had no change in visual acuity． Conclusion Laser-induced chorioretinal venous anastomosis is a new therapeutic method for RVO， especially for nonischemic type and successful anastomosis can decrease the conversion rate of the vein occlusion to an ischemic state．
