The data table (n=83 variables) contains information obtained at follow-up visits during the AREDS clinical trial (every six months following randomization), annually in person during the natural history follow-up, and via phone between annual in-person visits. Variables include information about AREDS participants' ophthalmic medical history (e.g. cataract or other eye surgery, laser treatment for AMD, retinal repair, capsulotomy, presence/absence of lens, glaucoma, and visual acuity) and general medical information, including new diagnoses of cancer, heart disease, stroke, and peripheral vascular disease, disease history of angina and high blood pressure, current disease status of diabetes, arthritis, and gout, use of prescribed drugs for disease treatment or management (e.g. blood-thinning medications, digoxin, thyroid hormones, insulin), use of over-the-counter drugs (e.g. NSAIDs, antacids), and smoking behavior. For version 3 release of the study, visual acuity data of the right eye have been added for odd-numbered visits. Note: In version 3, the ID has been replaced by ID2 identifier for all subjects.
