Abstract: : Purpose: Although the Randot Stereotest is a commonly used stereoacuity test, little has been published concerning its use in young children. Furthermore, despite the reported sensitivity of stereoacuity to many vision anomalies, it is not performed routinely during children's vision examinations. Therefore, the purpose of this study was to 1) determine the completion rate of the Randot in young children, 2) calculate normative values, and 3) explore the value of the measuring stereoacuity by determining the ability of reduced stereoacuity to foretell fail status on a Modified Clinical Technique (MCT) vision screening. Methods: A masked investigation of Randot stereoacuity in 264 three- to seven-year-old school aged children was performed. A modified Modified Clinical Technique was used for vision screening. Results: A completion rate of 98.5% was found for the Randot. The median Randot stereoacuities of 100" in the three-year-olds, 70" in the four-year-olds, 50" in the five-year-olds, 40" in the six-year-olds, and 45" in the seven-year-olds in this group were better than those reported previously. Quantile testing revealed a significant difference between the current data and the previously published medians (three-year-olds: p=0.0014; four-year-olds: p=0.0008, and five-year-olds: p<0.0001). Logistic regression analysis revealed that reduced stereoacuity on the Randot was significantly predictive of failure status on the vision screening (>100": aOR=5.37; p<0.001). Conclusions: Previously reported stereoacuities for the Randot in preschoolers may be artificially high. Reduced stereoacuity was significantly predictive of failing the MCT vision screening. Stereoacuity can be assessed in the majority of young children and provides valuable clinical information.
