There is a consensus that age-related macular degeneration (AMD) is the result of (photo)-oxidative-induced retinal injury and its inflammatory sequelae, the latter being influenced by genetic background. The dietary carotenoids, lutein (L), zeaxanthin (Z), and meso-zeaxanthin (meso-Z), accumulate
To investigate the response of carotenoid supplementation in different phenotypes of early age-related macular degeneration (AMD) by measuring macular pigment optical density (MPOD) and retinal sensitivity.
Consecutive patients with only medium/large drusen and only reticular pseudodrusen (RPD) and
OBJECTIVE
To investigate the impact of three different macular carotenoid formulations on macular pigment optical density and visual performance in subjects with early age-related macular degeneration.
METHODS
Fifty-two subjects were supplemented and followed for 12 months, 17 of them were in
OBJECTIVE
To report the secondary outcomes in the Carotenoids with Coantioxidants in Age-Related Maculopathy trial.
METHODS
Randomized double-masked placebo-controlled clinical trial (registered as ISRCTN 94557601).
METHODS
Participants included 433 adults 55 years of age or older with early
Macular pigment (MP) is composed of lutein (L), zeaxanthin (Z) and meso-zeaxanthin (MZ). The present study reports on serum response to three different MP supplements in normal subjects (n 27) and in subjects with age-related macular degeneration (AMD) (n 27). Subjects were randomly assigned to:
The foveal region of the retina has a yellow pigmentation composed primarily of the carotenoids lutein and zeaxanthin. Past studies have shown that cigarette smoking depresses carotenoid concentrations in the blood. This is the first report on the effects of cigarette smoking on carotenoids in the
OBJECTIVE
Dietary carotenoids lutein and zeaxanthin may play a protective role against visual loss from age-related macular degeneration (AMD) through antioxidant and light screening mechanisms. We used a novel noninvasive objective method to quantify lutein and zeaxanthin in the human macula using
OBJECTIVE
To compare the impact of sustained supplementation using different macular carotenoid formulations on macular pigment (MP) and visual function in early age-related macular degeneration (AMD).
METHODS
Sixty-seven subjects with early AMD were randomly assigned to: Group 1 (20 mg per day
OBJECTIVE
It has been hypothesized that the macular carotenoids protect against age-related macular degeneration (AMD). In this study, the association between serum concentrations of carotenoids and the presence of AMD was evaluated in a case-control sample of elderly Chinese subjects.
METHODS
Two
Key epidemiologic studies show associations between high dietary intakes of certain carotenoid-containing fruits and vegetables and reduced risk of prostate cancer, breast cancer, head and neck cancers, cardiovascular disease, and age-related macular degeneration, although overall the evidence is
OBJECTIVE
To evaluate the relationships between the amount and type of dietary fat and intermediate age-related macular degeneration (AMD).
METHODS
Women aged 50 to 79 years with high and low lutein intake from 3 sites of the Women's Health Initiative Observational Study were recruited into the
OBJECTIVE
We tested variants in genes related to lutein and zeaxanthin status for association with age-related macular degeneration (AMD) in the Carotenoids in Age-Related Eye Disease Study (CAREDS).
METHODS
Of 2005 CAREDS participants, 1663 were graded for AMD from fundus photography and genotyped
Epidemiologic data indicate that individuals with low plasma concentrations of carotenoids and antioxidant vitamins and those who smoke cigarettes are at increased risk for age-related macular degeneration (AMD). Laboratory data show that carotenoids and antioxidant vitamins help to protect the
OBJECTIVE
A review of the role of the carotenoids, lutein and zeaxanthin, and their function in altering the pathogenesis of age-related macular degeneration (AMD).
METHODS
Medline and Embase search.
RESULTS
Recent evidence introduces the possibility that lutein and zeaxanthin, carotenoids found in
OBJECTIVE
Despite strong biological plausibility, evidence from epidemiologic studies and clinical trials on the relations between intakes of lutein and zeaxanthin and age-related macular degeneration (AMD) has been inconsistent. The roles of other carotenoids are less thoroughly
