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 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...
متن کاملMacular pigment optical density in a Brazilian sample
Background To evaluate macular pigment optical density (MPOD) and to identify its determinants in a sample of Brazilian individuals. Methods This was a cross-sectional study. One hundred three healthy individuals had both eyes photographed using a Visucam 500 digital fundus camera (Carl Zeiss Meditec, Jena, Germany) in combination with the MPOD module. Four variables were obtained: maximum MP...
متن کاملMacular pigment optical density in a South Indian population.
PURPOSE. To estimate the normal value of macular pigment optical density (MPOD) in an adult south Indian sample. METHODS. Three hundred eyes of 161 healthy volunteers (30 men and 30 women in each of the age groups of 20-29, 30-39, 40-49, 50-59, and ≥60 years) underwent MPOD measurement with a macular densitometer. Thirty-two eyes were also checked for intersession variability. RESULTS. The mean...
