Abstract:
The evaluation of stereoacuity provides relatively accurate assessment of binocular function. However, it is difficult to perform and also the reliability rate is low in the 2-to 5-year-old age range. We investigated the over-all success rate, the success rate according to age, and efficacy with the Randot preschool stereoacuity and Lang test in the 2-to 5-year-old children of 96 patients. The overall success rate of the two stereotests were 84. 4%, 47. 4%in the 2-year-old children and more than 87%in children over 3-year-old. When children with normal binocular vision were examined with the Randot preschool stereoacuity test, mean stereoacuity was 333 arc sec in the 2-year-age group, 135 arc sec in the 3-year-age group, 48 arc sec in the 4-year-age group, and 50 arc sec in the 5-year-age group. Sensitivity and specificity of Randot preschool stereoacuity test were 100%, 94. 2%, respectively. Sensitivity and specificity of Lang test were 100%, and 92. 4% respectively. As a result, Randot preschool stereoacuity and Lang stereotests might be considered easy available and valuable test for evaluating binocular function in the 3-to 5-year-old preschool children. Moreover, the Randot preschool stereoacuity provided a relatively accurate measurement of stereoacuity in the 3-to 5-year-old age range.
