Evaluation of the Accuracy of Bina Color Vision Test

Bina color vision test was devleoped by a local company in Iran. There was no information available about the quality and the accuracy of this test and no decision could be made about its clinical application. In order To determine its accuracy, this test was compared with Ishihara’s Pseudo Isochromatic Plates and H16 Panel test.
The participants were selected from the previous screenings in Tehran and Ghom provinces and were referred to an optometry practice. After performing a routine eye exam, the participants were tested under the same luminance condition using Bina panel test (developed in Iran), Ishihara’s PIPs (developed in Japan), and H16 panel test (developed in UK), in random order.Similar to H16 test, the procedure for Bina test was based on the manual. Bina test was repeated 30 minutes after completion of the final test.
A total of 94 participants with no color vision defects, and 76 with color vision defect (detected by Ishihara’s PIP), with no other pathology, participated in the study. With H16, 94 individuals showed no defects, 57 were diagnosed with color vision defect, and in 19 participants the type of defect could not be diagnosed. With Bina test, 94 individuals showed no defects, 61 were diagnosed with color vision defect, and in 15 individuals the type of defect could not be diagnosed. In diagnosing the type of defect, Bina test and H 16 showed 87.9% agreement (Kappa= 0.897). In diagnosing the type of defect, Bina test showed repeatability of 72% (Kappa=0.72).
The accuracy of diagnosis of color vision defect with Bina color vision panel test is adequate.
