Objective: To examine the influence of experience with colors
on the results of color-vision-testing with the color-arrangement-test
Roth 28-hue (E) desaturated.
Methods: Forty-four patients with color-experience (VW-Werk Wolfsburg)
were included and devided in two groups: group 1: non-smokers without
ophthalmological and systemic diseases (n = 27, 42±9 years), group
2: smokers without ophthalmological and systemic diseases (n = 17; 43±8
years). The control group 3 (n = 30; 42±4 years) included non-smokers
without color-experience, ophthalmological or systemic diseases and the
control group 4 (n = 10; 42±8 years) smokers without color-experience,
ophthalmological or systemic diseases. Besides the ophthalmological examinations
(visual acuity, refraction, intraocular pressure, slit lamp and fundus
examination) the color-vision was tested by the color-arrangementtest
Roth 28-hue (E) desaturated monocularly under standard conditions: The
background used was black cardboard, illuminated by two Osram fluorescent
lamps (L36W/12LDL Daylight) providing 2000 lux at the test table.
Results: Ophthalmological examination in all subjects was without
pathological findings. The mean error score in the group 1 (median ±
mean absolute deviation: 48±47) was lower than in the control group
3 (median ± mean absolute deviation: 72±45; p=0,02). The
mean error score in group 2 (median ± mean absolute deviation:
60±60) was lower than in the control group 4 (median ± mean
absolute deviation: 156±65; p=0,0014). No statistical significant
difference was found between the measurement of the right or left eye.
Conclusion: Color-experience improve the results in the colorarrangement-
tests like the Roth 28-hue (E) desaturated.
