Case #69: LifeMeter in Clinical Practice and the value of carotenoid testing in AMD – Page 21 of 28

LifeMeter in Clinical Practice FAF Case Examples:

FAF imaging is helpful to see the effect that supplementation has on the macula pigment visually:

• The highest density of macular pigments exists in the foveal area which blocks the normal autofluorescence of the RPE in the macula.
• Absorption of the 488 nm blue light by macular pigments, especially the carotenoids lutein and zeaxanthin, cause hypo-autofluorescence of the central macula.
• Macular pigments block 488 nm-AF more intensely than 580 nm-AF.²⁹
