Changes in color vision with decreasing light level: separating the effects of normal aging from disease

Abstract: This is the unspecified version of the paper.This version of the publication may differ from the final published version. The purpose of this study was to obtain additional information about the health of the retina (HR) by measuring the rate of loss of chromatic sensitivity with decreasing light level. The HR index is introduced to separate the effects of normal aging from early stage disease. For normal subjects the HR index is largely independent of age (r 2 ∼ 0.1), but ∼11% of clinically normal, asymptomat… Show more

“…Modern graphics cards for control of computer-based color vision tests have become popular because of their ease of use, ability to test simultaneously different directions in color space, and incorporation of rigorous psychophysical procedures {e.g., Cambridge Color Test (CCT) [15,16] and Color Assessment and Diagnosis (CAD) test [17]}. All of these tests are designed based on congenital color vision deficiencies, but they also have proven valuable for detecting acquired deficiencies of color vision [1822]. …”

“…Absolute thresholds for detection of flashed stimuli, however useful, are often the final component of visual function to be affected in disease. Sensitivity for detection of fine spatial detail, motion and colour signals can be selectively damaged in many diseases of the eye and often precedes visual field loss (Barbur and Konstantakopoulou 2012, Bergin et al 2011, Hawkins et al 2003, Lee 1991, Westcott et al 1998, Bullimore et al 1993, Zihl et al 1983, Marré and Marré 1986, Verriest 1963, Krastel and Moreland 1991. Cerebrovascular accidents have also been shown to cause impaired contrast sensitivity (Fisk et al 2002) and colour vision loss (Rauscher et al 2011).…”
