Brief Summary

Background: Age-related macular degeneration (AMD) and cataracts are two eye diseases. They were studied in the Age-Related Eye Disease Study (AREDS2) and the AREDS2 Follow-On study. These studies followed the natural course of the diseases. They also provided data on the long-term effects of certain oral supplements on AMD. Objective: To study the long-term effects of oral supplements on several things. These include incidences of lung cancer, development of late AMD, cataract surgery, cognitive function, and cardiovascular events. Eligibility: Former AREDS2 and AREDS2 Follow-On participants Design: Participants will have 1 visit. It will include: An eye exam that tests how well participants can see, measures eye pressure, and checks eye movements. The pupil will be dilated with eye drops. Pictures will be taken of the retina and the inside of the eye. Participants will grip a device in their hand to measure their grip strength. A blood sample will be taken. This will be stored for future genetic research. Cells may be created from the sample. A small sample of skin will be taken. Sponsoring Institution: National Eye Institute
