[The border lines between the 3 forms of trichromaticity in anomaloscopic examinations (author's transl)].
After presentation of the up to date knowledge on transition form between normal and protanomalous trichromates as well as the gap between normal and deuteranomalous trichromates and author reports on 20,000 investigations of his own on colour vision. Registration of all special cases since 1957 are presented. With reference to the large material it is found that, when all important factors of this investigation are condidred, there is a relatively sharp border between normal and the deuteranomalous at an Ag of 1.75, whereas in the transitional zone of Ag 0.4-0.85 there is marked overlapping between protanomalous and normal trichromates especially in the region of Ag 0.6-0.8. Whereas a differentiation between normal and the deuteranomalous is easily made through the Ag further methods, especially observation of the position of the yellow serew of the anomaloscope. Are always required to differentiate between normal and protanomalous trichromates.
