Light exposure and macular pigment optical density.
PURPOSE Biochemical research has demonstrated that lutein and zeaxanthin, the two macular carotenoids, are bleachable pigments. Further, evidence suggests that exposure to UV light can degrade plasma carotenoid levels in vivo. The present study investigated the effects of exposure to normal levels of light on the levels of lutein and zeaxanthin in the retina. METHODS The optical density of ma...
متن کاملMacular pigment optical density and photophobia light threshold
Light absorption by macular pigment may attenuate visual discomfort, or photophobia, for targets composed of short-wavelength light. Macular pigment optical density (MPOD) and photophobia light thresholds were measured psychophysically in 10 subjects. The energy necessary to induce photophobia for a short-wavelength target relative to a long-wavelength target was linearly related to MPOD, as we...
متن کاملEffects of lutein supplementation on macular pigment optical density and visual acuity in patients with age-related macular degeneration.
PURPOSE There is evidence from several large-scale clinical trials that reduced intake of lutein, a major component of the macular pigment, is a risk factor for the development of AMD. In the present study (LISA; Lutein Intervention Study Austria) it was hypothesized that lutein supplementation increases macular pigment optical density (MPOD). In addition, an investigation was conducted into wh...
متن کاملLower Macular Pigment Optical Density in Foveal-Involved Glaucoma.
PURPOSE To evaluate the relationship between macular pigment optical density (MPOD) and structural parameters of the macula and optic nerve head in glaucomatous eyes. DESIGN A cross-sectional analysis of the baseline data collected during the Macular Pigment and Glaucoma Trial (ISRCTN registry number: 56985060). PARTICIPANTS Eighty-eight subjects (48 male, 40 female) with a diagnosis of ope...
متن کاملMacular pigment optical density in a Central European population.
BACKGROUND AND OBJECTIVE The purpose of this study is to measure the macular pigment optical density and study its spatial profile as well as identify its determinant factors in a Central European population. PATIENTS AND METHODS The macular pigment optical density (MPOD) and its distribution were assessed in 228 eyes of 129 subjects using fundus reflectometry with the Visucam 500 (Carl Zeiss...
