Comparison Between the Best Stereopsis Test and the Stereo Fly Test.
Purpose: The Bernell Evaluation of Stereopsis Test (BEST): Dinosaur Version is a new polarized-free stereopsis test designed to measure local stereopsis. This test has two distinctive features: (1) it uses lenticular technology to create color images in order to improve interest to the subjects, and...

This test has two distinctive features: (1) it uses lenticular technology to create color images in order to improve interest to the subjects, and (2) it is designed to overcome the shortcomings of apparent motion and monocular cues associated with other polarized stereo acuity tests. The purpose of this study is to compare the BEST with a standard polarized stereopsis test, the Stereo Fly test. Methods: Forty-five subjects (mean age 26 +/- 3.77 years) were tested with the BEST and Stereo Fly tests following a complete binocular vision examination. The stereopsis obtained in the BEST (test 1: clip-art animals) was compared with the Stereo Fly test (Wirt circles). Results: The results show a moderate correlation (Spearman's rho: r=0.612, p<0.0001) between the BEST (Test 1: clip-art animals) and the Stereo Fly test (Wirt circles). The stereopsis values measured by the two tests were not significantly different from each other (Wilcoxon signed rank test, Z=-0.733, p=0.75). The BEST was found to be in good agreement (k=0.60, 95% CI 0.28 to 0.91) with the Stereo Fly test in measuring stereopsis in adults with normal binocular vision. Conclusion: The results demonstrate that the BEST is comparable to the Stereo Fly test in measuring stereopsis in adults with normal binocular vision. Further studies in diverse patient populations, such as young children and developmentally disabled patients, are required in order to determine the value and application of the different sections of the BEST when compared with other clinical stereopsis tests. pubtype: Academic Journal doctype: pictorial research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
