The carotenoids lutein and zeaxanthin are believed to protect the human macula by absorbing blue light and quenching free radicals. Intestinal malabsorption syndromes such as celiac and Crohn’s disease are known to cause deficiencies of lipid-solub

As in humans and monkeys, lutein [(3R,3'R,6'R)-beta,epsilon-carotene-3,3'-diol] and zeaxanthin [a mixture of (3R,3'R)-beta,beta-carotene-3,3'diol and (3R,3'S-meso)-beta,beta-carotene-3,3'-diol] are found in substantial amounts in the retina of the Ja

Recent epidemiological studies have suggested that the consumption of tomatoes and tomato-based food products reduce the risk of prostate cancer in humans. This protective effect has been attributed to carotenoids, which are one of the major classes

With the use of a modified microvascular corrosion casting technique in healthy eye-bank eyes from a 77-year-old woman 9 hours post mortem, a large communication between the central retinal and posterior ciliary arterial systems was demonstrated. The

We describe resonance Raman imaging (RRI) of macular pigment (MP) distributions in the living human eye. MP consists of the antioxidant carotenoid compounds lutein and zeaxanthin, is typically present in high concentrations in the healthy human macul

PURPOSE. The xanthophyll carotenoids lutein and zeaxanthin, along with their major metabolites, meso-zeaxanthin, and 3oxolutein, are highly concentrated in the human macula. In addition to these two metabolites, there are still others that have not y

There is growing evidence that high levels of the macular xanthophyll carotenoids lutein and zeaxanthin may be protective against visual loss from age-related macular degeneration. To study this protective effect further, it is important to measure m

Background It has been hypothesized that the macular carotenoid pigments lutein and zeaxanthin may protect against macular and retinal degenerations and dystrophies. Objective To test this hypothesis by objectively measuring lutein and zeaxanthin lev
