Intravitreal bevacizumab injection for management of macular edema in branch retinal vein occlusion

Purpose: The aim was to evaluate visual and anatomical outcome of intravitreal bevacizumab (IVB) in eyes with macular edema (ME) due to branch retinal vein occlusion (BRVO). Methods: Retrospective, consecutive case series. Study was done on 26 eyes of 26 patients. Outcome measures include: Best corrected visual acuity (BCVA), central macular thickness (CMT) by spectral domain optical coherence tomography, and complications. Results: BCVA improved by a mean of 3.2 lines from an initial mean BCVA: 0.1 (counting fingers: 1 m-0.3) to a mean BCVA 0.4 (0.05-0.8) over the follow-up period of 6.9 months (4-12 months). CMT was reduced from an initial mean of 613 (401-959 μ) to the mean of 400 μ (274-623 μ) at the end of the follow-up period. No complications were recorded. This was achieved through a mean number of injections: Four with a range (3-6 injections). Conclusion: IVB is an effective treatment for ME secondary to BRVO. There was a significant improvement of VA and significant reduction in macular thickness in many cases, but not in all cases.
