Purpose
This study evaluated the long-term outcomes of eyes with neovascular age-related macular degeneration (nAMD) treated with aflibercept according to a treat-and-extend (T&E) regimen for up to 5 years.
Methods This retrospective study included 112 eyes of 111 patients with nAMD who received aflibercept according to the T&E regimen. The patients received 3 monthly injections of aflibercept followed by a T&E regimen for at least 12 months. Data, including best-corrected visual acuity (BCVA), treatment interval, presence of exudation, central retinal thickness, and central choroidal thickness were analyzed.
Results
Of the 112 consecutive eyes, 66 completed the 5-year follow-up. After 5 years of treatment, BCVA (logMAR) was significantly better than baseline (0.29 ± 0.31 at baseline and 0.18 ± 0.23 at 5 years, P < 0.01). A mean of 7.0 ± 1.5 injections in the first year and 4.9 ± 2.2 injections per year thereafter were required. In eyes with subretinal hyperreflective material (SHRM) at baseline, BCVA at baseline and 5 years were significantly worse than in eyes without SHRM at baseline and 5 years. However, the eyes with SHRM required fewer injections and exhibited greater BCVA improvement.
Conclusion
This retrospective study demonstrated the effectiveness of the T&E regimen with aflibercept in managing nAMD over a 5-year period, maintaining significant improvements in BCVA.
