METHODS: Totally 62 patients with retinal vein occlusion complicated with macular edema were diagnosed in the Ophthalmology Department of our hospital during 2017-03/09 were randomly divided into three groups. Group A was treated by retinal laser alone, and groups B and C were treated with intravitreal injection of conbercept and rezuzumab respectively before retinal laser a follow-up of 6mo was conducted to observe the clinical efficacy of three groups.

RESULTS: After treatment, the retinal thickness(CMT)in macular center of the three groups was significantly lower than that before treatment, and the CMT of groups B and C were lower than that of group A(P<0.05), but there was no difference between the two groups(P>0.05). At 6mo after treatment, the total effective rate of the three groups was 44%, 86% and 86%, respectively(P<0.05), and the total effective rate of groups B and C was higher than that of group A(P<0.0167).

CONCLUSION: Vitreous injection of conbercept or ranibizumab combined with retinal laser in treatment of retinal vein occlusion with macular edema can effectively reduce macular edema and improve vision. Conbercept or ranibizumab has similar effects.
