Abstract

Purpose: To assess the real-world 5-year treatment outcomes of ranibizumab therapy in Japanese patients with neovascular age-related macular degeneration (AMD). Methods: This was a retrospective, observational, and open-label effectiveness study that included 295 eyes. The participants were patients with treatment-naïve neovascular AMD who received intravitreal ranibizumab (IVR) monthly injection at least three times as the loading phase, followed by further injections as needed (pro re nata (PRN)) and follow-up assessments for 5 years. Outcomes were determined at least 5 years after the first ranibizumab injection. Results: Mean logMAR best-corrected visual acuity (BCVA) at baseline was 0.52. The mean BCVA significantly improved after three loading injections; however, it declined gradually. The BCVA at 1 year was significantly better than the baseline BCVA, whereas the 3-year, 4-year, and 5-year BCVA values were significantly lower than the baseline values. The average central foveal thickness improved significantly from 366 ± 125 μm to 268 ± 134 μm (p < 0.0001). Macular atrophy was significantly more likely to occur in cases with classic choroidal neovascularization (CNV) than in cases with other AMD (p = 0.01). Conclusions: IVR is well tolerated in eyes with AMD. However, a PRN regimen for AMD may have limited real-world effectiveness for long-term maintenance of improved visual acuity. Macular atrophy may occur more frequently in classic CNV. To maintain good vision, IVR treatment should be started earlier and performed continuously.
