BACKGROUND AND OBJECTIVE: Clinical trials in neovascular age-related macular degeneration (nAMD) demonstrate that high visual acuity (VA) can be maintained, and low VA can be improved with anti-vascular endothelial growth factor (VEGF) treatment. Few real-world data investigating the relationship between baseline VA and long-term outcomes exist. This study compares VA at diagnosis and after treatment using data from a large patient registry. PATIENTS AND METHODS: Retrospective study of IRIS Registry patients diagnosed with nAMD in one or both eyes between January 2013 and June 2017. Patients received at least two anti-VEGF injections in the study eye(s) less than 45 days apart during the study period. Primary outcomes were the percentage of eyes with 20/40 VA or better at diagnosis and association of VA at diagnosis with longer-term visual outcomes. RESULTS: The study included 162,902 eyes. Among all included eyes, 34.3% presented with 20/40 VA or better at diagnosis. Patients with 20/40 vision or better at baseline maintained a mean VA of 20/40 or better for 2 years after treatment initiation. CONCLUSIONS: Baseline VA at nAMD diagnosis predicts long-term VA outcomes. Early diagnosis before VA is adversely affected is a key factor in preserving vision in patients with nAMD.
