Evaluation of the desaturated Roth 28 HUE colour test — preliminary results

Abstract

In order to quantify colour vision deficiencies, we have evaluated the desaturated Both 28 HUE colour test for error scores in 95 normal subjects (71 males, 24 females) with no ocular or general chronic disease who were tested monocularly under standard conditions. The background was a black cardboard; illumination consisted of two fluorescent lamps (Osram L18W/11, Germany). The subjects were divided into four age groups: 0-19, 20-39, 40-59 and 60-79 years. Quantitative analysis was performed using specially developed software. The mean error score in the colour test was 66+/-35 (minimum 0, maximum 174; median 60). There were no differences between the right or left eye (p = 0.6, Mann-Whitney test), or between males and females (p = 0.64, Mann-Whitney test). No correlation was found between age and error score (regression coefficient = -0.027; p = 0.94). Based on these data, error scores on the desaturated Both 28 HUE test appear to be stable over age.
