Fluorescence Lifetime Imaging Ophthalmoscopy and the Influence of Oral Lutein/zeaxanthin Supplementation on Macular Pigment (FLOS) – A pilot study

Oral lutein (L) and zeaxanthin (Z) supplementation enhances macular pigment optical density (MPOD) and plays a protective role in the development of age-related macular degeneration (AMD). Fluorescence lifetime imaging ophthalmoscopy (FLIO) is a novel in vivo retinal imaging method that has been shown to correlate to classical MPOD measurements and might contribute to a metabolic mapping of the retina in the future. Our aim was to show that oral supplementation of L and Z affects the FLIO signal in a positive way, in patients with AMD.
