Visual acuity screening in the preschool population: A comparison of two tests

1 May 1990


Acuity measurement in adults is generally done with the Snellen acuity chart, however, acuity assessment in preschoolers must often utilize alternative methods. This study compared the Light House Acuity Test to the Broken Wheel Acuity Test to determine whether or not the Broken Wheel Acuity Test is a viable test for assessment of visual acuity in the preschool population in a screening situation. Results indicate that the tests have good correlation of acuity values and both procedures yielded high testability rates. Four year old children showed slower testing time than five year old children, but there was no significant difference in final acuity reached. Final choice of visual acuity screening tests should be based on individual responses of the child and on the individual preference of the examiner.
