The relationship between short-wavelength-sensitive acuity and macular pigment optical density in the ageing eye.

Research output: Other contribution

Abstract

Introduction: This study investigates the relationship between foveal short-wavelength-sensitive (SWS) orientation identification acuity and measures of macular pigment optical density (MPOD) in the ageing eye.Methods: Orientation identification acuity was measured in the fovea and at 12 degrees eccentricity (nasal visual field) under S-cone isolating conditions in 62 participants (aged 20 – 71) free from ocular disease and with clear ocular media. MPOD was measured at 0.5 degrees eccentricity from the foveal centre using a heterochromatic flicker photometry based densitometer instrument from MacularMetrics. Results: Reduced SWS orientation identification acuity was associated with increasing age in the fovea (r= -0.57, p0.4 log units, 31 participants) (r= -0.17, p= 0.35).Conclusions: MPOD was not significantly related to age in this study. SWS orientation identification acuity declined faster in the fovea than the retinal periphery for the group as a whole. Individuals with lower baseline levels of MPOD (
