title: [Comparison of congenital color vision deficiencies prevalence between Han and Uygur high-school students].
abstract: OBJECTIVE
  A population-based study was conducted to compare the prevalence of congenital color vision deficiencies (CVD) in high-school students of Uygur and Han nationalities in Xinjiang Uygur autonomous region.
  
  
  METHODS
  Students from 7 high schools were examined with pseudoisochromatic color plates and further with Farnsworth Munsell 100 test. The chi-square test was applied to compare categorical variables, and the independent-samples t test was used to compare the measure data.
  
  
  RESULTS
  In the study population of 3764 Uygur students, 88 students had CVD, including 69 males and 19 females. 48 of 2055 Han students were diagnosed with CVD, including 46 males and 2 females. No significant difference existed in the prevalence of CVD in boys between two nationalities. The prevalence of CVD in Uygur girls was higher than that in Han girls.
  
  
  CONCLUSIONS
  No significant difference was found in the prevalence of CVD in boys between two nationalities. The prevalence of CVD in Uygur girls was higher than that in Han girls.
