Colour vision and spectral sensitivity in children with visual handicaps.
In children with a visual handicap, colour vision testing may provide additional cues to diagnosis. Some information is given by pseudo-isochromatic plates. More informative are the arrangement tests, especially the Panel D-15. These tests can be used also in cases with severely reduced visual acuity. In suspected achromatopsia, the scotopic spectral sensitivity can be revealed by the D-15 test, the anomaloscope, or measuring the spectral sensitivity.
