Purpose: To compare functional and anatomic outcome of intravitreal ranibizumab (IVR) and intravitreal aflibercept (IVA) treatments in neovascular age-related macular degeneration by using the treat and extend (TE) protocol. Methods: In this retrospective chart study, treatment naïve 74 eyes of 74 age-related macular degeneration patients treated with IVR and IVA (38 eyes in IVR and 36 eyes in IVA group) with TE protocol were included. Following three consecutive monthly intravitreal injections, TE protocol was applied to each group. Patients were followed up for at least 36 months. Mean change in best-corrected visual acuity (BCVA), central macula thickness (CMT) and injection numbers over 3 years were compared. Results: Among 36 months period, the mean number of injections was 17 ± 4 for both groups (p > 0.05). In terms of CMT, there was no statistically significant difference between groups at 36 months compared to baseline. A decrease of 72.55 ±39.37 μm in CMT was detected in IVR group, whereas the decrease was 70.58 ± 33.96 μm in IVA group (p > 0.05). There was a significant increase in BCVA at 36 months of measurements. In addition, BCVA demonstrated an increase of 4.1 ± 0.44 letters in IVR group and 4.36 ± 0.67 letters in IVA group after 36 months compared to the baseline (p > 0.05). Conclusions: Both IVR and IVA injections provided significant improvements and stability in BCVA and CMT, however there was no significant difference between IVR and IVA injections with TE protocol of 36 months.
