Outcomes included visual acuity (VA), central retinal thickness (CRT) and safety.Results: The mean age was 79.5± 7.7 years. The majority of patients (67.7%) were female and all patients were Caucasian. Most patients previously received ranibizumab with only 17.5% of patients being treatment-naïve. The injection frequency declined over time irrespective of prior treatment status (p< 0.0001), with treatment-naïve eyes receiving a mean of 4.2± 2.9 yearly injections and prior-ranibizumab eyes 3.6± 2.7. Regression analysis confirmed first-year VA increases for treatment-naïve eyes (p=0.002) followed by a slight decrease of − 1.8 letters per year. For prior-ranibizumab eyes, the visual changes over 1 year were statistically non-significant (p=0.90) but declined slightly after year one (p< 0.0001). Anatomically, the CRT of treatment-naïve eyes decreased over time from baseline (p< 0.0001), ...
