Macular pigment spatial distribution effects on glare disability.
PURPOSE This project explored the relationship of the macular pigment optical density (MPOD) spatial profile with measures of glare disability (GD) across the macula. METHODS A novel device was used to measure MPOD across the central 16° of retina along four radii using customized heterochromatic flicker photometry (cHFP)at eccentricities of 0°, 2°, 4°, 6° and 8°. MPOD was measured as discret...
متن کاملMacular pigment and visual performance in glare: benefits for photostress recovery, disability glare, and visual discomfort.
PURPOSE One theory of macular pigment's (MP) presence in the fovea is to improve visual performance in glare. This study sought to determine the effect of MP level on three aspects of visual performance in glare: photostress recovery, disability glare, and visual discomfort. METHODS Twenty-six subjects participated in the study. Spatial profiles of MP optical density were assessed with hetero...
متن کاملGlare disability, photostress recovery, and chromatic contrast: relation to macular pigment and serum lutein and zeaxanthin.
PURPOSE A large body of research has linked macular lutein and zeaxanthin to reduced risk of degenerative eye disease. The earliest published hypothesis for the role of the pigments was not based on chronic protection but immediate function. Recent data on macular pigment (MP) have shown that screening the foveal cones from short-wave light does, in fact, result in improvements in photostress r...
متن کاملThe macular pigment. II. Spatial distribution in primate retinas.
The spatial density distribution of macular pigment in primate retinas was described by two-wavelength microdensitometry of retinal sections. The macular pigment is most dense along the path of the receptor axons in the center of the fovea. Another band of high density is present in the inner plexiform layer in many retinas. The density in both fiber layers declines to low, relatively constant ...
متن کاملMacular pigment distribution in Stargardt macular disease.
PURPOSE To investigate macular pigment optical density (MPOD) and distribution in patients with Stargardt disease. METHODS Prospective observational case series. The study included 13 eyes of 13 consecutive patients. A modified confocal scanning laser ophthalmoscope (SLO, Heidelberg, Germany) was used for MPOD measurement. It calculated the MPOD at 0.5° of the center of the fovea, and MPOD in...
