Macular 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...
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 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 کاملEthnic differences in macular pigment density and distribution.
PURPOSE Many epidemiologic studies suggest a number of risk factors that may be associated with progression of age-related maculopathy (ARM). In this study, the authors investigate ethnic differences in macular pigment density (MPD) and macular pigment (MP) distribution. METHODS Inclusion criteria were healthy subjects, aged 35 to 49 years, visual acuity >or=20/20, race ethnicity white non-Hi...
متن کاملMacular pigment and age related macular degeneration.
The present concepts of the pathogenesis of AMD include cumulative light damage by oxidative processes in the macular photoreceptors as environmental co-factor for the development of AMD. The direct causative connection of this hypothesis has still to be established but wide circumstantial evidence from epidemiological and basic scientific investigations are strongly supportive. Macular pigment...
