Sahlgren's saturation test for detecting and grading acquired dyschromatopsia.
A new sorting test requires only two minutes for quantitative estimation of saturation thresholds for bluish pigment colors. The test is highly sensitive to and specific for differences between normal subjects and individuals with acquired color vision defects. When combined with Ishihara's pseudo-isochromatic plates, it discriminates between congenital and acquired dyschromatopsias and identifies subjects with combined defects.
