Long-Term Visual Outcome in Wet Age-Related Macular Degeneration Patients Depending on the Number of Ranibizumab Injections

Purpose. To analyse the visual outcome in wet age-related macular degeneration (AMD) patients depending on the number of ranibizumab injections. Methods. 51 naïve wet AMD patients were retrospectively recorded. Visual acuity (VA), central retinal thickness (CRT) measured with spectral domain (SD) op...

description Purpose. To analyse the visual outcome in wet age-related macular degeneration (AMD) patients depending on the number of ranibizumab injections. Methods. 51 naïve wet AMD patients were retrospectively recorded. Visual acuity (VA), central retinal thickness (CRT) measured with spectral domain (SD) optical coherence tomography (OCT), and number of intravitreal injections were compared at 6, 12, 18, 24, 30, and 36 months of follow-up. Kaplan-Meier survival rates (SRs) based on VA outcomes were calculated depending on the number of ranibizumab injections performed. Results. VA improved compared with baseline at 6 and 12 months (P<0.005). No differences were found at 18, 24, 30, and 36 months (P>0.05). CRT measured with Cirrus OCT decreased (P<0.001) at all time points analysed. The mean number of injections received was 6.98±3.69. At 36 months, Kaplan-Meier SR was 76.5% (the proportion of patients without a decrease in vision of more than 0.3 logMAR units). VA remained stable (≤0.01 logMAR units) or improved in 62.7%. Within this group, SR was 92.9% in those who received 7 or more injections versus 51.4% receiving <7 treatments (P=0.008; log-rank test). Conclusion. Better VA outcomes were found in stable wet AMD patients after 3 years of follow-up if they received ≥7 ranibizumab injections.
