Summary

This study is following 5,000 adults aged 65 and older to learn how eye diseases develop and progress over time. Researchers will collect detailed health information, eye exams, and biological samples to build a comprehensive database. The goal is to create a personalized risk prediction tool that helps detect age-related eye problems earlier and improve precision medicine for older adults.
