Abstract
A number of visual acuity tests are available for both the literate and the preliterate child. This paper compares the results obtained with five different visual acuity tests; Illiterate E, Landolt C, Bailey-Hall Cereal test, Lighthouse Flash Cards and Stycar Five Letter test, for 43 children between the ages of three and five years. The linear Illiterate E test appears to be the test of choice; it will detect amblyopia, and the results are not significantly different from those obtained for the single optotype tests. No significant differences were found between the results for the different single optotype tests used in this study. The Landolt C test results are significantly different from those for the other tests and we do not recommend this test for young children.
