Abstract
One hundred nineteen school children with normal binocular vision were tested on the Titmus Stereotest, the Randot Stereotest, and the TNO test. Our results show that 93% of the subjects were able to complete the entire test on the Randot and the Titmus, and achieved 20″ and 40″ respectively. Only 2.5% of the subjects could complete the TNO to achieve 15″ and 16% attained 30″. The Randot and the TNO did not produce any false positives, while the Titmus and the Randot gave the most repeatable answers.
