- Congenital colour deficiency is classified into three types; monochromatism, dichromatism and anomalous trichromatism. The most frequent types are protan and deutan, These X-linked recessive disorders have an incidence of 4.5-10% in men and 0.2-0.4% in women. Dichromats may fail to discriminate colours needed to properly perform tasks in both school and work life. The anomalous trichromat has less restriction than the dichromat. Individuals with congenital colour deficiency may not be aware of anomalous color perception. Color vision plays an important role in aspects of life. Hence, it is imperative that the diagnosis of color deficiency be made early in life.
