[An epidemiological study of congenital dyschromatopsias in schoolchildren]

Taking into consideration that present-day communication is based on colours and shapes, the prevalence of anomalies in the chromatic sight in the red-green axis has been studied in the school boys of the city of Albacete.

The test of Ishihara has been used in an aleatory representative sample; and dyschromatopsic pupils, so classified in this test, have been further explored with the anomaloscopy Pickford-Nicolson, in order to know their anomaly kind and degree.

The prevalence obtained is similar to those reported by other studies carried out in the European white race.

Taking into account the transcendence of this phenomenon, we consider that this exploration must be included in the systematic examinations at school labour and general level.
