Abstract
Purpose
To assess the efficacy and safety of intraocular injections of bevacizumab in patients with macular edema (ME) following branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO).
Methods
Retrospective, non-comparative case series. Patients ≥18 years of age with ME secondary to BRVO or CRVO who received a minimum of one intravitreal injection of bevacizumab with a follow-up >3 months were included. Primary endpoints were mean change in best corrected visual acuity (BCVA) from baseline to 12 and 24 months, and mean change in central macular thickness (CMT) after 3 injections. Secondary endpoints were mean change in BCVA and CMT from baseline to end of follow-up, number of injections, and ocular adverse events.
Results
Eighty-seven eyes with BRVO and 65 eyes with CRVO were included. Mean follow-up time was 24.4 and 26.1 months in the BRVO and CRVO groups, respectively. The mean change in BCVA was 0.25 LogMAR in the BRVO group and −0.118 LogMAR in the CRVO group.
Conclusion
Visual acuity outcomes in the CRVO group were poorer, especially in patients with low baseline BCVA.
