  • Title: Comparison of the Farnsworth-Munsell 100-Hue, the Farnsworth D-15, and the L'Anthony D-15 desaturated color tests.

    Journal: Arch Ophthalmol; 1993 May; 111(5):639-41. PubMed ID: 8489445.
    Abstract:
    OBJECTIVE: The Farnsworth-Munsell 100-Hue, the Farnsworth D-15, and the L'Anthony D-15 desaturated color tests were administered to patients with glaucoma to determine whether the D-15 or D-15 desaturated color tests could be used to predict performance on the 100-Hue test in clinical populations. METHODS: The three color tests were administered to 35 patients with glaucoma. The results were analyzed using the method of Vingrys and King-Smith that calculates an angle (type of color loss) score, S-index (measure of the randomness of cap arrangement), and a C-index (a measure of the severity of color loss) based on the cap arrangement. RESULTS: The 100-Hue error score was significantly related to the D-15 and D-15 desaturated C-indexes. Furthermore, the 100-Hue S-index could be predicted from the D-15 or D-15 desaturated S-indexes. The 100-Hue angle could not be predicted from the D-15 or D-15 desaturated color tests. CONCLUSIONS: The D-15 desaturated color test (which requires significantly less time to administer) may be used to assess the severity of color vision deficit in some patient populations.
