Lipofuscin results from digestion of photoreceptor outer segments by the retinal pigment epithelium (RPE) and is the principal compound that causes RPE fluorescence during autofluorescence imaging. Absorption of the 488-nanometer blue light by macular pigments, especially by the carotenoids lutein
OBJECTIVE
To compare serum Lutein and Zeaxanthin (L/Z) concentrations between patients with nonproliferative diabetic retinopathy (NDR) and normal subjects, and to explore the effect of L/Z supplementation on serum L/Z level and visual function in NDR patients
METHODS
SUBJECTS WERE DIVIDED INTO
BACKGROUND
meso-Zeaxanthin (MZ) is a xanthophyll carotenoid with profound antioxidant activity.
OBJECTIVE
Oxidative stress plays a decisive role in numerous degenerative diseases including cancer. The present study evaluates anti-inflammatory effect of MZ.
METHODS
Balb/c mice were treated with
OBJECTIVE
Macular pigment (MP) is the collective name for three isomeric carotenoids: lutein, zeaxanthin, and meso-zeaxanthin. Macular pigment density is greatest in the central retina, peaking at the fovea and falling to negligible levels at 7 degrees of eccentricity from the fovea. Several studies
OBJECTIVE
To summarize major innovations in retinal disease management during fiscal year 2014.
METHODS
Literature review.
METHODS
A subset of papers published in the peer-reviewed literature were selected.
RESULTS
Major innovations in retina include: (1) advances in the treatment of diabetic
OBJECTIVE
Macular pigment, composed of lutein, zeaxanthin, and meso-zeaxanthin, is postulated to protect against age-related macular degeneration, likely because of filtering blue light and its antioxidant properties. Macular pigment optical density (MPOD) is reported to be associated with macular
OBJECTIVE
To determine whether macular pigment optical density (MPOD) is related to serum lutein or serum zeaxanthin in patients with retinitis pigmentosa.
METHODS
The authors measured MPOD with heterochromatic flicker photometry, serum lutein and serum zeaxanthin by high performance liquid
