| Abstract |
Description of the Lanthony D-15 desaturated panel (D-15-d), a simple 15 cap colour arrangement test, designed to identify mild acquired dyschromatopsia (colour vision loss), which can be administered rapidly in the field. The panel was evaluated among 23 solvent-exposed workers of a paint manufacturing plant by comparing the results with it and those obtained with the Farnsworth-Munsell 100 Hue (FM-100), a highly sensitive measure of colour vision loss. The D-15-d revealed a significantly higher prevalence of dyschromatopsia among the 10 highly exposed workers (80%) as compared to the 13 moderately exposed workers (30.8%); FM-100 results revealed 1 false positive. All dyschromatopic workers presented blue-yellow loss; the FM-100 detected 8 complex patterns, while the D-15-d identified 5. D-15-d and FM-100 scores were highly correlated (corr. coeff. 0.87; p<0.001). Multiple regression analyses showed both scores to be significantly related to age and exposure level. The findings of this study indicate that the D-15-d is an adequate instrument for field study batteries. However, the FM-100 should be used for more detailed assessment. |
