Dyschromatopsia

The above term describes the impossibility of normal perception of colors. Most forms of dyschromatopsia are congenital and more rarely acquired. In the case of much rarer color blindness, only white, black and gray color are perceived. From dyschromatopsia suffers about 6-8% of the normal male and 0.4% of the normal female population.

      Normal Color Perception                       Dyschromatopsia

More common is the difficulty of perception of the green color (50%), followed by the complete inability to see green (25%), the complete inability to see the red (15%) and the complete inability to see the red (15%). and finally, the difficulty of perception of red (10%).

Dyschromatopsia does not cause any other kind of symptoms and almost always occurs in otherwise healthy eyes.

The main cause of acquired deficiency in color vision is the taking of medicines.

Treatment of congenital dyschromatopsia does not exist. In case of acquired form, partial rehabilitation occurs if diagnosed in time and the drug that caused it is discontinued.

The diagnosis of dyschromatopsia is made among other things with the paintings test of Ishihara.
