Study of the Effects of Supplements on Eye Disease in Participants From the Age-Related Eye Disease Study
NCT01915238 · View on ClinicalTrials.gov ↗
Study Summary
Background: \- 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. Objectives: \- To learn more about the effect of oral supplements on AMD. Eligibility: \- People who completed the AREDS2 study. Design: * Participants will have up to 2 study visits over 6 18 months. * Each visit will last up to 5 hours. The visits will be combined with annual follow-up visits in the AREDS2 study if possible. * At each visit, participants will undergo an eye exam and photography. * The eye exam includes testing sight, measuring eye pressure, and checking eye movements. To examine the inside of the eye, the pupil will be dilated with eye drops. * Photographs of the inside of the eye may be taken during the eye exam and while the eyes are dilated. * A contact lens may be placed on the eye briefly to look at the retina at the back of the eye.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01915238
The ClinicalTrials.gov registry entry for NCT01915238 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 52 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Eye Institute (NEI), which has 214 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with AMD appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01915238 reports 2 study locations spanning 2 distinct geographic areas — top geographies include Maryland, North Carolina. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
