title: [Occurrence of anisometropia among students ranging from 6 to 18 years of age].
abstract: OBJECTIVE
  To determine the prevalence of anisometropia among students ranging from 6 to 18 years of age.
  
  
  METHODS
  5023 students from elementary schools, junior high schools and high schools, aged 6-18 years were examined. Measurements of visual acuity as well as retinoscopy after cycloplegia have been carried out. The data were analyzed using chi-square test and the coefficients of rang Spearman's correlation were calculated.
  
  
  RESULTS
  It was found that 6% of the students suffer from anisometropia. No influence of the students' age on the prevalence of anisometropia was observed. It was found that anisometropia occurs more frequently among boys than among girls.
