In this observational study researchers want to learn more about changes in visual acuity (clarity of vision) with proactive flexible treatments over time in patients suffering from wet age-related macular degeneration (wAMD) after decision to treat with Aflibercept (Eylea) was made. Wet AMD is an eye disease that progressively destroys the macula, the central portion of the retina, impairing central vision.
