title: [The Ohkuma's test: an evaluation].
abstract: Ohkuma's pseudoisochromatic test was evaluated in 147 subjects including 130 cases with hereditary dyschromatopsias, and compared with the color vision tests of Ishihara, the HRR, the Farnsworth Panel D-15 and the City University Color Vision Test. Qualitatively, Ohkuma's test was more exact for the diagnosis of the axis of the dyschromatopsia (protan or deutan); quantitatively, Ohkuma's test was of good efficiency for screening, but the quantitative gradation was mediocre, indicating dichromatism in only 3/4 of the cases.
