Abstract

Background/Aims To compare the efficacy of ranibizumab (0.5 mg) with aflibercept (2 mg) in the treatment of cystoid macular oedema due to branch retinal vein occlusion (BRVO) over 12 months.

Methods A multicentre, international, database observational study recruited 322 eyes initiating therapy in real-world practice over 5 years. The main outcome measure was mean change in EDTRS letter scores of visual acuity (VA). Secondary outcomes included anatomic outcomes, percentage of eyes with VA >6/12 (70 letters), number of injections and visits, time to first inactivity, switching or non-completion.

Results Generalised mixed effect models demonstrated that mean (95% CI) adjusted 12-month VA changes for ranibizumab and aflibercept were similar (+10.8 (8.2 to 13.4) vs +10.9 (8.3 to 13.5) letters, respectively, p=0.59). The mean adjusted change in central subfield thickness (CST) was greater for aflibercept than ranibizumab (−170 (−153 to –187) µm vs −147 (−130 to –164) µm, respectively, p=0.001). The overall median (Q1, Q3) of 7 (4, 8) injections and 9 (7, 11) visits was similar between treatment groups. First grading of inactivity occurred sooner with aflibercept (p=0.01). Switching was more common from ranibizumab (37 eyes, 23%) than from aflibercept (17 eyes, 11%; p=0.002).

Conclusion Visual outcomes at 12 months in this direct comparison of ranibizumab and aflibercept for BRVO in real-world practice were generally good and similar for the 2 drugs, despite a greater effect of aflibercept on CST and time to first grading of inactivity.
