ABSTRACT

Objective: To determine the prevalence of dyschromatopsia in an open population in the city of Puebla and the municipality of Chalchicomula de Sesma. Material and methods: Observational, descriptive cross-sectional study, the presence of deuteranopia and protanopia was developed through the Ishihara test. Results: The sample was 358 people, finding 8 cases of alterations in color perception. Obtaining that 2.23% (8) of the participants presented alterations in color vision. Our results show that there is no statistically significant association between sex (p=0.228), hours of screen time per day (p=0.453) and the presence of Protanopia/Deuteranopia, however, the mean age of participants with dyschromatopsia was significantly higher than that of participants without dyschromatopsia (p=0.043). Conclusions: By identifying the presence of deficiencies in color perception, the need for greater attention to early diagnosis and the design of inclusive educational and work strategies to improve the quality of life of affected people is highlighted.
