[Trial and evaluation of a new test to examine color vision (author's transl)].

With the new Rodenstock color test disk it is possible to distinguish with 99% accuracy between deuteranopia and protanopia. In addition, the diagnosis is quantitatively correct (anomaly or anopia) in 92% of deuteranopia and 98% of protanopia cases. A special scheme for evaluation is presented. Special emphasis was placed on describing exactly the function of this new method of examining inherited color vision deficiencies. Only persons who were already known to have defective color vision were tested. Therefore, no conclusions can be drawn regarding the efficiency of detection of color vision deficiencies.
