The primary objective of LUTEGA is it to determine the long term effect (about 1 year) of the supplementation with a fixed combination of lutein/zeaxanthin and omega-3- fatty acids on the ...
The macular pigment (MP) in humans consists of the yellow, blue-absorbing carotenoids lutein and zeaxanthin. The highest concentrations of lutein and zeaxanthin are found in the fovea. Sin...
The purpose of this study is to determine cross-sectional relationships between macular pigment optical density (MPOD) and visual performance in glaucoma. Additionally, the investigators w...
The macular pigment (MP) in humans consists of the yellow, blue-absorbing carotenoids lutein and zeaxanthin, which are contained in vegetables and fruits. The highest concentrations of lut...
Earlier investigations have detected low levels of macular pigment (MP) in the center of the fovea and a halo of MP at a higher eccentricity in persons with type 2 idiopathic juxtafoveal t...
Study of lutein and zeaxanthin content in the diet with the assessment of the relationship between the level of alimentary intake of non-vitamin carotenoids and the density of the macular region of the retina at a young age.
Lutein and zeaxanthin are carotenoid pigments that affect the function of the visual analyzer. They selectively accumulate in the yellow spot of the retina, form macular pigment and determine the dens...
Vision depends on the delivery of vitamin A (retinol) to the retina. Retinol in blood is bound to retinol-binding protein (RBP). Retinal pigment epithelia (RPE) cells express the RBP receptor, STRA6 t...
Goji berry (Lycium barbarum L.) is one of the important economic crops due to its exceptional nutritional value and medicinal benefits. Although reduced sugar levels in goji berry exposed to long-term...
1. To evaluate the repeatability of macular pigment optical density (MPOD) measurements in non-mydriatic and mydriatic conditions with a single wavelength reflection photometry. 2. To compare the non-...
We compare visual acuity (VA) to contrast sensitivity (CS) testing in assessing "real-world" visual performance and recommend that both should be measured routinely in the clinic. A new model to impro...
A yellow pigment that accumulates in the MACULA LUTEA. It is composed of LUTEIN, meso-zeaxanthin, and ZEAXANTHIN.
The use of light interaction (scattering, absorption, and fluorescence) with biological tissue to obtain morphologically based information. It includes measuring inherent tissue optical properties such as scattering, absorption, and autofluorescence; or optical properties of exogenous targeted fluorescent molecular probes such as those used in optical MOLECULAR IMAGING, or nontargeted optical CONTRAST AGENTS.
A form of MACULAR DEGENERATION also known as dry macular degeneration marked by occurrence of a well-defined progressive lesion or atrophy in the central part of the RETINA called the MACULA LUTEA. It is distinguishable from WET MACULAR DEGENERATION in that the latter involves neovascular exudates.
Autosomal dominant hereditary maculopathy with childhood-onset accumulation of LIPOFUSION in RETINAL PIGMENT EPITHELIUM. Affected individuals develop progressive central acuity loss, and distorted vision (METAMORPHOPSIA). It is associated with mutations in bestrophin, a chloride channel.
A protein family characterized by a highly conserved N-terminus and four to six transmembrane helices; they function as bicarbonate permeable, calcium-activated chloride channels. Bestrophin-1 (BEST-1) and bestrophin-2 are highly expressed in human RETINAL PIGMENT EPITHELIUM cells and mutations in the BEST-1 gene are associated with VITELLIFORM MACULAR DYSTROPHY, TYPE 2.
