Abstract:

Macular Pigment (MP) is the collective name for three carotenoids, Lutein(L), Zeaxanthin(Z) and Meso-zeaxanthin, which are uniquely concentrated in the central retina. Due to the anatomic position of the MP, it has the ability to alter the spectral composition and energy of the incident light upon photoreceptors. In addition to its short wavelength filtering properties, MP also possess potent antioxidant qualities that have become the subject of interest for a wide range of retinal conditions. The term Macular Pigment Optical Density (MPOD) refers to a quantifiable value of an MP concentration in the central retina. Studies have indicated that supplementation of the constituents of MP is associated with increased levels of MPOD that have resulted in the improved visual function and decreased pathology in a number of retinal conditions, most notably age-related macular degeneration and diabetic maculopathy. Studies of neural processing have also found significant, positive correlations between cortical levels of L and Z and cognitive function including verbal fluency, memory and processing speed. MPOD has shown significant, positive associations with cortical L and Z supports the hypothesis that MPOD may act as a proxy measurement for cortical levels of L and Z. Underlying these associations is the need for repeatable, accurate measures of MPOD that can provide peak optical density and spatial distribution. This presentation will review the current understanding of the role of MP within the aging adult, clincal measurement techniques, strategies for improved visual function and cognition as well as a reduced risk of retinal disease.
