Comparing stereoscopic performance of children using the Titmus, TNO, and Randot stereo tests.

Abstract

The stereo acuities of 112 children between 3 and 11 years of age were assessed using the Titmus, TNO, and Randot stereo acuity tests. Results indicated that stereo acuity test scores improved with age and that performance variability decreased with age. Normal adult findings were achieved by age 7. Generally the Randot Stereo test yielded the best stereo acuity performances. It was concluded that the Randot stereo test is a better clinical test for use with children than either the Titmus or TNO stereo tests.
