Purpose: To assess the efficacy of intravitreal bevacizumab (IVB) combined with grid photocoagulation in the management of recurrent macular edema secondary to retinal vein occlusion (RVO). Methods: This is a prospective, non-randomized, interventional study. Thirty five eyes with branch retinal vein occlusion (BRVO) and 15 eyes with central retinal vein occlusion (CRVO) were treated with grid photocoagulation combined with IVB for recurrent macular edema. The visual acuity, central macular thickness and intraocular pressure were outcome measures. The mean duration of follow-up was 18.1 ± 3.6 months. Results: One month after treatment, 45 of the 50 eyes showed complete resolution of the cystoid space. Compared with initial values, final central macular thickness was reduced significantly in both BRVO and CRVO groups (P < 0.001), but improvement in VA was significant only for eyes with BRVO (P = 0.012). The total number of IVB was 1.8 ± 0.3 for eyes with either BRVO or CRVO. Conclusion: IVB combined with grid photocoagulation is an effective treatment for reducing recurrent macular edema associated with RVO.
