[Representation of normal and pathologic macular color vision].

INTRODUCTION

The computerized chromatic test allows a graphic visualization of the colors perceived by normal and pathologic retina.

MATERIAL AND METHOD

This test was returned by an album (six series of plates with ten levels of saturation), a lamp and a program for graphic representation.

RESULTS

The graphic image was returned by the computer. For a normal eye, the aspect of the chart was a set of ten concentric saturation levels: the most saturated circle were located on the outside. For an acquired or congenital dyschromatopsia, the limits of the neutral zone are located in the center and are constituted by the most saturated level of blind charts of the album.

DISCUSSION AND CONCLUSION

The informatized chromatic test is a very easy one to appreciate color vision defects.
