[In Press] Development of new test to diagnose color vision disturbance

AIM: To develop a new test for the diagnosis of color vision deficiency.METHODS: Cross-sectional study with 203 subjects (121 females and 82 males) who performed detection tests of color vision disturbance using Ishihara''s original test images and the images created for the new test in print and electronic version. Images of the new test were created in computer with a tool to control the three colors, which formed the central number, and the seven colors, that compose the background of the image.RESULTS: Eight males demonstrated color vision deficiency (prevalence of 3.94% in the total sample and 9.75% in the male sample). There were no identified dyschromatopsia carriers in females. The comparative analysis between the images of the original Ishihara test with the new test (eletronic version and printed) demonstrated, in both cases, a high correlation (96%) between the results of the tests. Although the high correlation between the results, the cutoff point for defining the existence of color vision deficiency was higher than the original Ishihara test, to obtain 100% sensitivity and 100% specificity.CONCLUSION: The new developed test is able to identify subjects with dyschromatopsia similar to the original Ishihara test. The test will also provide an option to create images with geometric elements or simple figures for the test in children.
