As described in the Macular Anatomy section, Macular Pigment protects the macula from free-radical damage caused by blue wavelength light. A risk factor for developing AMD is low Macular Pigment Optical Density (MPOD). There is now a device called the Densitometer that measures MPOD, the relative health of your macula. The macula is the sight-sensing center in the back of the eye

The three major components of the tissue are the carotenoid pigments Meso-zeaxanthin, Zeaxanthin and Lutein. On the surface, one’s macula may appear healthy. However, if the levels of the carotenoid pigments are low, this may predispose one to developing AMD. By measuring MPOD, we can now identify at risk patients. Low MPOD is a modifiable risk factor for the development of AMD. Risk reduction can begin now, even if you are in your twenties.

Supplementation with the proper amounts of Meso-zeaxanthin, Zeaxanthin and Lutein has been shown to increase MPOD. In fact, 94% of patients will show increased MPOD after six months of supplementation. Raising one’s macular pigment levels now may prevent the onset of the disease in the future.
