Abstract

The criteria for a good stereoacuity test in preschool children should be easy and provide accurate measurement of stereoacuity.To determine the success rate and efficacy of stereoacuity tests, and percentage of children between age of 2 and 3 years who correctly identified shapes and symbols of each stereoacuity test, we administered the Lang, Titmus circle, Titmus, animal, Randot circle, Randot shape and Randot preschool stereoacuity test in 96 patients whose ages ranged between 2 to 5 years. The overall success rates of the Lang, Titmus circle Titmus animal, Randot circle, Randot shape and Randot preschool stereoacuity tests were 84.4%, 72.9%, 75%, 75%, 75%and 84.4%, respectively.The overall success rates of the Lang and Randot preschool stereoacuity test tended to be higher among the methods.The sensitivity of the Lang and Randot preschool stereoacuity test was 100%and best among all methods.The percentage of 2-to 3-year-olds who correctly identified the shape of star, cat, car, elephant, rabbit, hand, truck, house, tree and round was higher than that of other shapes. The shapes of squirrel, monkey, heart, E, and cross was lower than that of other shapes.The Lang or Randot preschool stereoacuity test which uses shapes and symbols readily recognizable by children was found to be easy and accurate stereotests for preschool children, especially in uncooperative 2-to 3-year-olds.
