[The Teller Acuity Card Test: possibilities and limits of clinical use]

The Teller Acuity Card test was used to examine 49 normal children, 77 with strabismus, 9 with anisometropia and 19 with various organic ocular diseases. The vision of some of these children was also tested with the Landolt C and fixation preference tests. A comparison of the three tests showed that strabismic amblyopia is not reliably detected with the Teller Acuity Cards. On the other hand, this test appears to be a good one for detecting loss of acuity due to ocular diseases.
