Abstract

Purpose: To characterize the rate of rod-mediated sensitivity decline with age using a PC-driven cathode ray tube (CRT) monitor. To provide data regarding the repeatability of the technique. Methods: Dark adaptation was monitored for 30 min following a minimum 30 % pigment bleach, using a white 1 stimulus (modulated at 1 Hz), presented 11 below fixation on a CRT monitor. Thirty-three subjects with no ocular pathology and normal fundus photographs were divided into two groups: older (≥45, n = 16) and younger (
