Epidemiological Study on Congenital Dischromatopsis in School Children

Abstract

Backgrkound: Taking into consideration that present-day communication is based on colours and shapes, the prevalence of anomalies in the chromatic sight in the redgreen axis has been studied in the school boys of the City of Albacete. Methods: The test of Ishihara has been used in an aleatory representative sample; and dischromatopsical pupils, so classified in this test, have been further explored with the anomaloscopy Pickford-Nicolson, in order to know their anomaly kind and degree. Results: The prevalence obtained is similar to those reported by other studies carried out in the European white race. Conclusions: Taking into account the transcedence of this phenomenon, we consider that this exploration must be included in the systematic examinations at school labour and general level.
