Abstract

<em><strong>Objective:</strong></em> To determine the prevalence of impaired color vision and visual motor dysfunctionin a group of children aged between five and fifteen years in the localities of Fontibon, PuenteAranda and Usaquén in Bogota. <em><strong><em><strong>Methodology:</strong></em></strong></em> We conducted a descriptive study in 243 patientswho were studying in schools representing each locality. Each child was subjected to the Ishiharaand Farnsworth tests of visual-motor integration (vmi). Statistical analysis was performed usingcontingency tables and ji2 (c2). <em><strong><em><strong>Results:</strong></em></strong></em> The prevalence of impairments in color vision was 6.7%(6/89 Ishihara test) and 14.6% (13/89 Farnsworth test) for the Spanish school in Puente Aranda, 2.4% (2/84 Ishihara test) and 4.8% (4/84 Farnsworth test) for the Pablo Neruda school in Fontibón,and 2.9% (2/70 Ishihara test) and 10% (7 / 70 Farnsworth test) for the La Salle School in Usaquén.The prevalence of visual-motor dysfunction was 55.1% (49/89) for the Spanish school in PuenteAranda, 28.6% (24/84) for the Pablo Neruda school in Fontibón, and 18.6% (13/70) for the LaSalle School in Usaquén. <em><strong>Conclusions:</strong></em> The prevalence of impaired color vision and visual motordysfunction was higher in the villages of Puente Aranda and Fontibon than in the town of Usaquén.
