Sensitivity, Specificity and Efficiency of Teller Acuity Cards for Detecting Amblyopia

ABSTRACT

The Teller acuity card procedure, which is a form of the preferential looking test, is a way of assessing visual acuity in preverbal patients. It has been shown to be rapid and easy test to perform. Teller acuity cards were used to detect amblyopia in 100 patients(from 2 months to 9 years) and the result was compared to the clinical judgement of amblyopia. The sensitivity, specificity and efficiency of Teller acuity card procedure compared to the clinical judgement of amblyopia were 71.43%, 94.94% and 90.00%, respectively. The authors found that the acuity cards could be used to detect amblyopia. However, the clinical judgement of amblyopia of the ophthalmologist was more sensitive in diagnosing amblyopia than the Teller acuity cards in the presence of various ocular disorders.
