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
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
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),
AREDS2 is a multi-center, 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 long-chain polyunsaturated fatty acids (LCPUFAs) as a treatment for age-related macular degeneration
Early age-related macular degeneration (AMD) is an early hallmark of irreversible vision impairment accompanying with senescence of macular. Given the fact in treatment, prevention strategy is thought to be an efficient and robust approach to diminish early AMD patients in low-income countries,
One of the earliest manifestations of macular telangiectasia type 2 ("MacTel") is an acquired reduction and/or redistribution of the macular pigment carotenoids at the foveal center. Currently, the biochemical mechanisms and clinical significance underlying these changes are not known, but it seems
Rationale: In our pilot study (MEC 07-1-127) we saw an increase in both plasma as macular levels of lutein and zeaxanthin. Current believe is that this increase might help against the further deterioration of the retina seen in age-related macular degeneration (AMD) by scavenging for free radicals
The Age-Related Eye Disease Study (AREDS) Follow-Up protocol allows us to continue with the follow-up of participants who were enrolled in the clinical trial of antioxidant vitamins and zinc. The AREDS study was designed in the beginning to determine the clinical course and prognosis of age-related
The current proposed study is a necessary pilot study to prepare for a large-scale phase III randomized clinical trial planned to investigate whether oral supplementation with macular xanthophylls (lutein and zeaxanthin) and omega-3 long-chain polyunsaturated fatty acids (LCPUFAs) will decrease the
