Özet
Purpose: To report the effect of simultaneous dexamethasone and bevacizumab combination treatment in patients with macular edema secondary to branch retinal vein occlusion (BRVO). Methods: Treatment-naive patients who had a macular edema secondary to BRVO with a duration of less than 1 month were treated either with intravitreal bevacizumab (Group-1) or intravitreal bevacizumab simultaneously combined with dexamethasone intravitreal implant (Group-2). In both groups, patients received monthly bevacizumab injection during the first 3 months. Between months 3 and 12, all patients were allowed to receive pro-re-nata bevacizumab. In Group-2, the first dexamethasone implant injection was simultaneously received with first bevacizumab injections. The patients were evaluated for re-treatment after 6 months and 11 months for second and third dexamethasone simultaneously with intravitreal bevacizumab. Results: In Group-1, 35 eyes of 35 patients and in Group-2, 32 eyes of 32 patients were treated. The mean gains in BCVA were +10.7 letters in the Group-1 and +21.3 letters in the Group-2 (P = 0.021) at month 12. The mean reduction in Central Macular Thickness (CMT) from the baseline were -173.74 μm in the Group-1 and -257.97 μm in the Group-2 (P = 0.0018). In Group-1, the mean intravitreal bevacizumab injection number was 7.18 ± 1.05. In Group-2, the mean intravitreal bevacizumab and dexamethasone injection number was 5.15 ± 1.24. There was a significant difference in mean injection numbers between 2 groups (P = 0.044). Conclusion: In the early period of macular edema adding dexamethasone to bevacizumab therapy does improve visual acuity and CMT, and reduce the injection frequency more than bevacizumab alone.
