The validity of the Frisby stereotest as a measure of precise stereoacuity.
This paper reports the outcomes of a study that compared the performance of 20 binocular adults on the Frisby stereotest and the TNO. (All subjects were prescreened with the Random-dot E stereotest administered at 1.5 m.) Significant intercorrelations were found (Pearson r = .73; two-tailed p less than .001), adding support to the clinical usefulness of the Frisby stereotest. Other characteristics of the two tests--including communication requirements and administration time--are compared.
