Welcome to The Age-Related Eye Disease Study 2 (AREDS2) was a multi-center, randomized trial designed to assess the effects of oral. The Age-Related Eye Disease Study 2 (AREDS2) Research Group* . AREDS2 was designed to test whether adding lutein + zeaxanthin, DHA. Lutein + Zeaxanthin and Omega-3 Fatty Acids for Age-Related Macular Degeneration: The Age-Related Eye Disease Study 2 (AREDS2).

Administrative, srudy, or material support: A zinc dose of 80 mg was used in the original AREDS formulation because it was the dose used in an earlier trial suggesting efficacy.
Currently, cataract surgery is one of the most common surgeries conducted in the US. Although the primary outcome was determined on color fundus photography, when available, fluorescein angiography and OCT images are sent to the Reading Center to confirm the presence of neovascular AMD.
Carotenoid stury and bioconversion. All analyses were conducted using SAS version 9. The number of lung cancers was small, and the analyses of competing risk showed essentially no change in our mortality results.
A simplified aredz2 scale for age-related macular degeneration: Follow-up study visits were scheduled annually; follow-up also included telephone contact 3 months after randomization and subsequent telephone contacts at 6 months between study visits. Participants, investigators, study coordinators, and all other study personnel are masked to treatment assignment in both the primary and secondary randomizations.
Advanced age-related macular degeneration in non-study eye, large drusen in study eye b. Dietary carotenoids, vitamins A, C, and E, raeds2 advanced age-related macular degeneration. National Academies Press; The Age-Related Eye Disease Study AREDS demonstrated beneficial effects of oral supplementation with antioxidant vitamins and minerals on the development of advanced age-related macular degeneration AMD in persons with at least intermediate AMD bilateral large drusen with or without pigment changes.
All enrolled participants will be followed until November allowing arwds2 a median of 5 xreds2 of follow-up or until the Data and Safety Monitoring Committee DSMC has recommended earlier trial termination. Participants with less than large drusen in both eyes or in study eye. Funds were generously contributed to these contracts by the following NIH institutes: This reflects the change in clinical practice over time. To compute the necessary sample size, adjustments were made for projected deaths and losses to follow-up.
Oral areds22 in macular degeneration. Persons with systemic diseases, including oxalate kidney stones, Wilson disease, hemochromatosis, lung cancer, or other diseases associated with poor 5-year survival, were excluded.
The Cox proportional hazards modeling using the Wei, Lin and Weissfeld method for obtaining robust variance estimates allowing for dependence among multiple event times will be used to assess the treatment effect. However, these results will be clinically important for most persons who are at risk for developing AMD.
Causes and prevalence of visual impairment among adults in the United States. Advanced age-related macular degeneration in non-study eye, less than large drusen in study eye. We also have not tested for equivalency between low-dose zinc and high-dose zinc and between no beta carotene and beta carotene. Graefes Arch Clin Exp Ophthalmol.
Lipids, Learning, and the Brain: It is also important to talk to your ophthalmologist regarding taking appropriate supplements. Lutein and zeaxanthin and the risk of cataract: For participants with bilateral large drusen, both eyes are eligible as study eyes because both have the potential to develop advanced AMD.

AREDS2 Results Released
Compared with placebo, the HRs for development of moderate or worse vision loss were 0. Comparison of aeeds2 zinc vs high-dose zinc showed no evidence of a statistically significant effect, and there is insufficient evidence to provide a clinical recommendation. Methods All participants were randomly assigned to: The exploratory analyses of the secondary randomization were restricted to participants randomized to the 4 variations of the AREDS supplements.
Additional analyses stratified by tertiles, quartiles, and deciles eFigure 1 showed similar results, with the lowest stratum demonstrating a protective effect compared with the remaining strata.

Blood levels of vitamin C, carotenoids and retinol are inversely associated with cataract in a North Indian Population. Measurement of carotenoids, retinoids, and tocopherols in human lenses.
The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final citable form.
A previous report detailed the power calculation. Results 4, participants were enrolled at 82 clinical centers located in the U. Comparison with placebo in the primary qreds2 demonstrated no statistically significant reduction studt progression to advanced AMD hazard ratio [HR], 0.
This formulation was given as a mixture of antioxidant vitamins and minerals.
