Abstract

PURPOSE
To investigate the characteristics of congenital and acquired color vision defects with Seohan computerized hue test and SNU (Seoul National University) computerized color test and to help to discriminate between congenital and acquired color vision defect METHODS: from June 2003 to January 2004, patient with congenital and acquired color vision defect and visual acuities more than 20/30 underwent Seohan computerized hue and SNU computerized color tests. Their results were compared with each other. Quadrant analysis and RQ calculation were done. RESULTS: On Seohan computerized hue and SNU computerized color tests, congenital color vision defects showed mainly red-green color vision defects (p<0.01, paired t-test) while acquired color vision defects showed blue-yellow color vision defect(p<0.01, paired t-test). RQ had 95% sensitivity and 98% specificity with a standard of 1.5 by Seohan computerized hue test, and 96% sensitivity and 98% specificity with standard of 1.0 by SNU computerized color test, for the discrimination of congenital and acquired color vision defects (ROC curve, confidence interval 95%). CONCLUSIONS: Seohan computerized hue and SNU computerized color tests were effective to classify types of color vision defects and discriminate between the congenital and acquired color vision defects.
