A comparison between the Randot animals and the Randot forms in a screening setting

1 May 1990

Abstract

A comparison of the the Randot animals (non random dot stereotest, NRDS) and the Randot forms (random dot stereotest, RDS) was accomplished using 255 first grade children at a Pacific University elementary school screening. The purpose was to determine which of the two stereotests was clinically more sensitive for detecting vision problems in grade school children as indicated by failing any portion of the screening. The findings indicate that children with significant refractive errors (hyperopia, astigmatism and/or anisometropia) or any type of binocular anomaly do worse on the RDS than on the NRDS. Based on these results, a random dot stereotest would be a valuable test to include in a grade school screening programs, since it provides a substantial amount of information with relatively little effort and time.
