Objective: The aim was to study the effect of intravitreal bevacizumab injection (IVB), which is applied in macular edema treatment secondary to branch retinal vein occlusion (BRVO), on visual acuity and macular thickness. Material and method: The files of patients who has macular edema caused by branch retinal vein occlusion and who were applied intravitreal bevacizumab injection were studied retrospectively. Visual acuity (logMAR) in follow-ups of the patients before and after the injection and the macular thickness values of the quadrant of the occlusion were recorded and the effect of intravitreal bevacizumab on these parameters were analyzed. Results: 24 eyes of 24 patients, 17 of which are male and 7 of which are female, were included in the study. The mean age of the patients were 59.1±7.7. The mean visual acuity prior to the injection was determined to be 0.7±0.5 logMAR, and the mean macular thickness value 489.7±129.6µm. The mean injection number applied was 1.5±0.7. The mean follow-up time after the injection was 3.5±2.7 months. The mean macular thickness was determined to be 393.1±5.7µm and mean visual acuity was 0.5±0.1 logMAR in the 1st month. In the last follow-ups of the patients, the mean visual acuity was 0.26±0.28 logMAR and the mean macular thickness value was 317.4±71.5 µm. The increase in visual acuity and the decrease between first and last control after the injection was found statistically significant (p<0.001).  Conclusion: The intravitreal bevacizumab injection used in macular edema secondary to BRVO increases visual acuity and decreases macular thickness.
