Spatial Mapping Of Macular Pigment Optical Density And Its Relationship To Contrast Sensitivity And Glare Disability, Christopher Michael Putnam
Spatial Mapping Of Macular Pigment Optical Density And Its Relationship To Contrast Sensitivity And Glare Disability, Christopher Michael Putnam
Dissertations
This dissertation explored the relationship of the macular pigment optical density (MPOD) spatial profile with measures of contrast sensitivity (CS), glare disability (GD), relative glare disability (RGD) and intraocular light scatter. A novel device capable of measuring MPOD across the central 16 degrees of retina along 8 principle meridians using customized heterochromatic flicker photometry (cHFP) at eccentricities of 0, 2, 4, 6 and 8 degrees was built. MPOD was calculated as both discrete and integrated values at all measured retinal loci. CS was measured using vertical grating stimuli of 3, 6 and 9 cycles per degree (cpd) also presented at …
