Improvement of retinal function in early age-related macular degeneration after lutein and zeaxanthin supplementation: a randomized, double-masked, placebo-controlled trial

Ma L et al. – Early functional abnormalities of the central retina in the early age–related macular degeneration patients could be improved by lutein and zeaxanthin supplementation. These improvements may be potentially attributed to the elevations in macular pigment optical density.
