- The Age-Related Eye Disease 2 Study (AREDS2) looked at two eye diseases. These were age-related macular degeneration (AMD) and cataracts. Participants in that study took supplement pills and some participants had additional pictures taken of their eyes. That study is now over. Researchers want to do a follow-up study after participants finish taking the pills, to see if they cause long-term effects on AMD. This study will be combined with follow-up visits of the AREDS2 study if possible.
