Summary

This study will analyze health records from 2009 to 2024 to find out how many people in Germany have three serious eye conditions: wet age-related macular degeneration, diabetic macular edema, and retinal vein occlusion. Researchers will look at data from two large German health databases to track new cases and overall numbers, and see how factors like age and other health problems affect these diseases. The goal is to better understand these conditions and how they are treated, without giving any new treatments to participants.
