Ranibizumab versus aflibercept for macular edema due to central retinal vein occlusion: 18-month results in real-life data.

Abstract

The objective of this study was to compare the anatomical and functional outcomes of ranibizumab versus aflibercept for the treatment of macular edema due to central retinal vein occlusion (CRVO) in routine clinical practice. Participants in this observational study included 62 treatment-naïve patients with CRVO who received intravitreal injections of either ranibizumab or aflibercept. The demographic data, best-corrected visual acuity (BCVA) and spectral-domain optical coherence tomography (SD-OCT) characteristics were evaluated at baseline and at months 1, 2, 3, 6, 12 and 18 post-treatment. At month 18, the mean BCVA of ranibizumab-treated eyes increased 7.9 letters, compared to 7.4 letters for eyes receiving aflibercept, with a similar number of injections. There was no statistically significant difference between the two groups in letters or in central subfield thickness at month 18. At the end of the follow-up, 50% of patients in the ranibizumab group and 42.9% in the aflibercept group showed complete resolution of macular edema. Ranibizumab and aflibercept demonstrated similar anatomical and functional outcomes over 18-month follow-up in patients with macular edema due to CRVO, with a similar number of injections.
