Abstract

An international multicenter study was designed and carried out to evaluate the color vision screener (CVS) test for normal trichromats and congenital color deficients. Over 400 participants from nine international Colour Assessment and Diagnosis (CAD) testing centers completed the CVS and the CAD test on calibrated visual displays. The CVS had a sensitivity and specificity [95% confidence intervals] of 1.00 [0.98–1.00] and 0.99 [0.97–1.00] with a positive and negative predictive index of 0.94 and 1.00 for an assumed prevalence of 8%. The CVS is quick, efficient, and easy to use, and its sensitivity is equivalent to the optimal published Ishihara protocol.
