CARACTERIZACIÓN DE PROBLEMAS REFRACTIVOS EN LA POBLACIÓN DE 6 A 12 AÑOS DE LA ESCUELA PRIMARIA URBANA FEDERAL “2 DE MAYO DE 1812” EN LA COLONIA CENTRO DEL MUNICIPIO DE CUAUTLA, MORELOS

Abstract

Descriptive case study conducted in a basic school located in Cuautla, Morelos. In this investigation the prevalence of refractive errors is transversally analyzed in a population of 337 individuals, whose ages vary between 6 and 12 years old. In order to realize this study, distant and near visual acuity tests using an optotype projector and retinoscopies taken by a Welch Allyn© retinoscope were applied. The collected data is analyzed under different statistic techniques in order to characterize and compare the prevalence of such refractive errors under the criteria of age and gender. The study showed a 27.2% prevalence of refractive errors among the attended patients. The most prevalent refractive error found was myopia (12.9%). Most of refractive errors were located under +/-1.00 D. Finally, characterizing refractive errors by age and gender showed no significant differences between groups.
