Abstract

In order to find a successor for the Hardy, Rand and Rittler (AOH-R-R) test the author made a comparison between the AOH-R-R and the Tokyo Medical College (TMC) tests in acquired dyschromatopsia. The diagnosis of the TMC type of a red-green defect is often in contradiction with the results of other color vision tests. In grading the severity of a red-green defect the TMC classification is shifted with regard to the AOH-R-R classification. A corrected grading in better agreement with the AOH-R-R classification is proposed. The TMC blue-yellow screening plates are more sensitive than the AOH-R-R blue-yellow screening plates. A TMC (supermild) blue-yellow defect in general corresponds to blue-yellow defects detected by FM 100 Hue and its derivatives. In the study of acquired dyschromatopsia, it is necessary to use a test battery. In our opinion the TMC can be used in such a test battery although it is not a real successor to the AOH-R-R. If ever the AOH-R-R is reprinted, the blue-yellow plates should be extended to a 'supermild' degree as are the TMC blue-yellow plates.
