Results from studies involving cells, animal models and clinical trials have demonstrated that lutein and zeaxanthin potentially protect against chronic diseases, including age-related macular degeneration, cataracts, coronary heart disease and stroke. Plasma concentrations of lutein and zeaxanthin
Neurodegeneration of the optic nerve and associated ganglion cell death in glaucoma leads to several well-characterized losses in visual function, most notably progressive peripheral visual field loss. Several recent studies have characterized significant visual function deficits in glaucoma
Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly.[1] The disease is categorized into early, intermediate, or advanced stages based on the severity of symptoms. The advanced stage, including GA and CNV, involves central region of the retina, which leads to a
Objective: The overall objective of this extended follow-up study is to provide data regarding the incidence of late age-related macular degeneration (AMD), cataract surgery and lung cancer in the approximately 1,200 AREDS2 study participants enrolled in the Follow-on study. The specific objectives
While being benefited from the results of previous studies, the sample size of the research was type 1 error performance α=0.05 and type 2 error performance β=0.20. The power of the test was taken as 1-β=0.80 and the power analysis was statistically made with NCCS PAS 11 program. 200 individuals
The macula of the human retina (the structure responsible for high acuity vision essential for reading, driving and recognizing faces) is colored an intense yellow due to the deposition of two carotenoid compounds, lutein and zeaxanthin. These xanthophyll carotenoids are derived exclusively from the
Methods: Patients with AREDS category 2 and 3 AMD were prospectively enrolled in this study, and were randomized to receive daily oral supplementation with lutein (12mg) + zeaxanthin (2mg) + astaxanthin (8mg) + omega-3 fatty acids (docosahexaenoic acid [DHA] 540mg + eicosapentaenoic acid [EPA]
Study parameters will include best corrected visual acuity, number of combination treatments, reduction of central foveal thickness by OCT measurement and development of exudative macular degeneration in the fellow eye. Follow up will include all patients with a minimum of two years. Retrospective
It is believed that the macular pigment protects the retina against photooxidative damage which can lead to agerelated macular degeneration (AMD). It is also hypothesized to enhance visual performance in normal human eyes. Much of the research into lutein supplementation has been centered around AMD
The age macular degeneration represents the first cause of blindness in industrialized countries if it is not treated. In France, the AMD affects 600 000 persons and this figure should continue to increase, notably because of the increase of the life expectancy. The macula is responsible of the fine
The Age Related Eye Disease Study 2 (AREDS2) was a multicenter Phase III randomized clinical trial designed to assess the effects of oral supplementation of high doses of macular xanthophylls (lutein and zeaxanthin) and/or omega-3 LCPUFAs as a treatment for age-related macular degeneration (AMD),
