Age-related Macular Degeneration (AMD) in the Vitamin D and Omega-3 Trial (VITAL)
This ancillary study to the VITamin D and OmegA-3 TriaL (VITAL) will examine whether vitamin
D3 and omega-3 fatty acids can help prevent the onset or progression of age-related macular
degeneration (AMD). The study will also examine whether vitamin D3 and omega-3 fatty acids
interact with each other, or with specific genes associated with AMD or vitamin D3 or
omega-3 fatty acid metabolic activity, to affect the risk of developing AMD.
