Abstract
Purpose
We examined the predictive factors for final visual acuity (VA) with macular edema of branch retinal vein occlusion (BRVO) treated by intravitreal injection of bevacizumab (IVB) and examined the differences between patients without recurrent macular edema due to BRVO after a single IVB and patients treated with multiple IVB because of recurrent macular edema.
Methods
In this retrospective study, 37 eyes of 37 patients with BRVO were treated with IVB and followed up for more than 24 weeks. Eighteen eyes showed no recurrence of macular edema after a single IVB (single IVB group). The remaining 19 eyes showed recurrent macular edema and underwent multiple IVB (multiple IVB group). VA and morphologic parameters of optical coherence tomography were examined.
Results
Mean VA, central retinal thickness, and mean retinal thickness in a circular region of 1-mm diameter at the fovea improved significantly with IVB treatment in both groups. Final VA was correlated with baseline VA and integrity grade of the photoreceptor inner and outer segment (IS/OS) line beneath the fovea.
Conclusion
Baseline VA and IS/OS line grade at 4 weeks may be predictive factors for final VA.
