Evaluation of a New Test for the Diagnosis of Congenital Dyschromatopsia in Children: the Color Vision Evaluation Test

Purpose To evaluate the validity, reproducibility, and feasibility of “Color Vision Evaluation Test” (CVET) for diagnosis congenital dyschromatopsia. Design Prospective, monocentric, sensitivity, specificity analysis study comparing CVET with Farnsworth 15 Hue standard test (15 STF). Methods A total 155 children from Paediatric University Hospital Nice were screened (both eyes) using Ishihara's pseudoisochromatic cards, which allowed dividing them into a dyschromatic group control group. All underwent twice STF at least 7 days between both series tests. Results Patients' mean age was 7.56 ± 3.51 years in 8.92 2.9 At first evaluation, sensitivity 95.7% 96.4%, respectively, 75% 58.9%, (P < .001). The reproducibility 100%, whereas that 88.4% = .01). explanation duration 18.8 seconds 17.7 .3). In group, always significantly longer than subjectively preferred to undergo rather 84.6% cases Conclusions is rapid, reliable, reproducible It accessible young children.
