Standardization of color vision and depth vision testing for validation in the Reisvo protocol

Abstract

<em><strong>Objective</strong><em> To establish a standardization protocol for Randot 2^® and Color Vision Testing Made Easy^® (CVTME^®), in order to use them as benchmark tests within the protocol of the Ibero-American Network of Visual and Ocular Health (REISVO). <em><strong>Methodology</strong><em> Clinical trials with methodological support, expert judgment, standardization of tests, and organization of pretest and pilot test were selected. A descriptive observational design was used for diagnostic test. The pilot test was conducted in 19 school children between ages 5 and 15 the assessment was carried out at the Optometry Clinic of the Universidad de La Salle. <em><strong>Results</strong><em> In the CVTME^® test, intra- and inter-examiner correlation provided a good degree of agreement among the observations: repeatability, reproducibility, and responsiveness to the test were 100%. In the Randot 2^® test, intra- and inter-examiner correlation provided a degree of agreement between low and good responsiveness to the test was 100%. <em><strong>Conclusions</strong><em> Data on agreement were good the intermediate precision level in the Randot 2^® test represents relative accuracy, both individually and in group. The CVTME^® test is robust and is not sensitive to external factors while the Randot 2^® test is sensitive to external factors, affecting measurement.
