Abstract Introduction: The aim of this study was to evaluate the ability of eight color vision tests to screen for and accurately measure hereditary color-deficiency in order to improve color vision assessment methods for aircraft pilots.
Methods: This prospective study included 29 color-deficient subjects and 23 healthy subjects. All performed the following tests: Ishihara plates, Farnsworth D15, Lanthony desaturated 15 Hue, Munsell 100 Hue, Beyne and Fletcher-Evans CAM lanterns, Nagel anomaloscope, and the Color Assessment and Diagnosis (CAD) test. The sensitivity and specificity of color-deficiency diagnosis were evaluated for each test, as well as the test's relevance for assessing aircraft pilots.
Results: The Ishihara plate test demonstrated a sensitivity of 0.97 and a specificity of 1.00 for color-deficiency screening. The CAD test and anomaloscope showed both a sensitivity and specificity of 1.00. The Beyne lantern, Fletcher lantern, Farnsworth D15, and the Lanthony 15 Hue tests all showed a specificity of 1.00 and sensitivities of, respectively, 0.69, 0.97, 0.58, and 0.79. During aircraft pilot selection tests, the CAD test classified 10% of color-deficient subjects as safe to fly, the anomaloscope 17%, and the Beyne and Fletcher lantern tests, respectively, 31% and 3%.
Discussion: The discrepancy in results confirms that current color vision test protocols need to be reassessed. The CAD test could be an interesting alternative to the series of tests used to assess flight crew, but it seems more selective than current tests.Marechal M, Delbarre M, Tesson J, Lacambre C, Lefebvre H, Froussart-Maille F.
