Key takeaways:
- The AREDS2 supplement slowed the expansion of geographic atrophy toward the fovea by approximately 55% over 3 years in patients with dry AMD.
- There was little benefit in those with GA in their central vision.
The original Age-Related Eye Diseases Study (AREDS), published in 2001, found that a supplement formulated with antioxidants — including vitamins C, E, and beta-carotene — as well as zinc and copper could slow the progression of intermediate to late-stage AMD. More than a decade later, the AREDS2 trial published in 2013 determined that substituting the antioxidants lutein and zeaxanthin for beta-carotene could not only improve efficacy but also prevent some risks. Neither study examined further benefits once patients progressed to late-stage disease.
New data show the AREDS2 supplement formulation slows the expansion of geographic atrophy toward the central foveal region, potentially preserving central vision in patients with late AMD
