Light exposure and macular pigment optical densityAdam J Wenzel
Department of Psychology, University of New Hampshire, 10 Library Way, Durham, NH 03824-3567, USA
Invest Ophthalmol Vis Sci 44:306-9. 2003..However, significant between-day variance indicates that multiple MPOD measures may be necessary to evaluate lutein and zeaxanthin levels in the retina accurately...
Compensation for light loss resulting from filtering by macular pigment: relation to the S-cone pathwayJames M Stringham
Vision Science Laboratory, University of Georgia, Athens, Georgia, USA
Optom Vis Sci 83:887-94. 2006..0 log unit. CONCLUSIONS: These results suggest that the visual system increases gain of the S-cone pathway to offset light absorption by MP...
Spatial profile of macular pigment and its relationship to foveal architectureJohn M Nolan
Department of Ophthalmology, Medical College of Georgia, Augusta, GA, USA
Invest Ophthalmol Vis Sci 49:2134-42. 2008..This study is an initial investigation of the relationship between the spatial profile of macular pigment and foveal architecture...
Compensation for light loss due to filtering by macular pigment: relation to hue cancellationJames M Stringham
Vision Science Laboratory, University of Georgia, Athens, GA 30602 3013, USA
Ophthalmic Physiol Opt 27:232-7. 2007..Such compensation must be required in order to maintain colour constancy across the retina where MP levels are changing quickly and dramatically...
Macular pigment and visual performance under glare conditionsJames M Stringham
Vision Science Laboratory, University of Georgia, Athens, GA 30602 3013, USA
Optom Vis Sci 85:82-8. 2008..In this study, we assessed the causality of this relation by supplementing lutein and zeaxanthin for 6 months while measuring MP, glare disability, and photostress recovery...
The glare hypothesis of macular pigment functionJames M Stringham
Vision Science Laboratory, University of Georgia, Athens, Georgia 30602 3013, USA
Optom Vis Sci 84:859-64. 2007..Past studies have shown that macular pigment (MP) reduces discomfort due to glare. In this study, we evaluated whether MP was related to visual performance under glare conditions...
Dietary lutein and zeaxanthin: possible effects on visual functionJames M Stringham
Vision Science Laboratory, Department of Psychology, University of Georgia, Athens 30602 3013, USA
Nutr Rev 63:59-64. 2005..This paper reviews recent studies investigating the influence of macular pigments on human visual performance. Such studies have offered insight into why lutein and zeaxanthin are uniquely concentrated in ocular tissues...
Macular pigment optical density and photophobia light thresholdAdam J Wenzel
Psychology Department, University of New Hampshire, 10 Library Way, Durham, NH 03824, USA
Vision Res 46:4615-22. 2006..Light absorption by macular pigment appears to influence the amount of short-wavelength light necessary to elicit photophobia...
Macular pigment optical density at four retinal loci during 120 days of lutein supplementationAdam J Wenzel
Psychology Department, University of South Carolina, Aiken, SC 29801, USA
Ophthalmic Physiol Opt 27:329-35. 2007..Increased consumption of lutein and zeaxanthin has been shown to increase macular pigment optical density (MPOD) in some individuals. Most interventions either obtained infrequent measures of MPOD or measured MPOD at a single retinal locus...
Action spectrum for photophobiaJames M Stringham
Department of Psychology, University of New Hampshire, Durham, New Hampshire 03824, USA
J Opt Soc Am A Opt Image Sci Vis 20:1852-8. 2003..It is therefore suggested that photophobia serves a function of biological protection. Results also suggest that photophobia is significantly mitigated by macular pigment in the short wavelengths...
