Ozawa Y, et al. – The goal of this study was to evaluate the use of the MPSII® device in an Asian population with or without age–related macular degeneration (AMD), to help optimize and establish macular pigment optical density (MPOD) values in a real–world, daily practice. Absolute, in contrast to estimated, the value was measurable in a limited number of aged participants; however, it was correlated with estimated value both in young and aged Asian populations with or without AMD. These outcomes may inform future clinical studies exploring the measurement of MPOD in understanding the role of macular pigments in the pathogenesis of AMD.
