Purpose: The purpose of this study was to compare the anatomical and functional outcomes of ranibizumab versus aflibercept for the treatment of diabetic macular edema (DME) in a long-term follow-up. Methods: Participants in this prospective study were 112 treatment naïve patients with DME, who received treatment with either intravitreal ranibizumab (n = 54) or aflibercept (n = 58). The demographic data, the best-corrected visual acuity (BCVA) and spectral-domain optical coherence tomography (SD-OCT) characteristics were evaluated at baseline and at month 1, 2, 3, 6, 12, and 18 post treatment, while factors affecting visual outcome were determined using multivariate analysis. Results: At month 18, the mean BCVA of ranibizumab-treated eyes increased 7.9 letters compared to 6.9 letters for eyes receiving aflibercept, with greater number of injections in ranibizumab group (9.2 ± 2.3 vs. 7.6 ± 2.1 injections in the ranibizumab and aflibercept group respectively, p = 0.0002). The difference in letters between the two groups was not statistically significant, nor the difference in central subfield thickness at month 18. Factors associated with poorer BCVA were found to be increasing age, HbA1c ≥7.5%, increasing central retinal thickness and disrupted ellipsoid zone. Conclusions: Ranibizumab and aflibercept presented similar anatomical and functional outcomes in 18-month follow-up in patients with DME. It is important to determine factors, affecting VA, so as to provide individualized treatment. © 2020 Informa UK Limited, trading as Taylor & Francis Group.
