Abstract

Purpose: To characterize the rate of scotopic sensitivity decline with age using cathode-ray-tube (CRT)-based dark adaptometry and compare the results with the macular pigment optical density (MPOD). Methods: Thresholds were measured following a minimum of 30% bleach, using a white 1° stimulus (flickering at 1 Hz), presented 11° below fixation on a CRT monitor. MPOD was measured using MPS 9000 based on heterochromatic flicker photometry. 33 subjects were divided into two groups: older (≥45, n = 16) and younger (
