Abstract

New technology has allowed us to realize the potential of imaging reflectometry in the fundus, as well as better understand the optical factors contributing to measurements. We are mapping photopigment density of human retinas to investigate photoreceptor/retinal epithelial function. We compare maps obtained from reflectometry with results from psychophysical techniques that measure photopigment optical density and visual function. These comparisons can be made across retinal eccentricity and retinal illuminance in the same observer.
