Study compares visual acuity tests in preschool children, revealing reliability and efficiency differences.
In a study comparing the Screening Test for Young Children and Retardates (STYCAR) and the New York Lighthouse Flash Card Test, 50 preschool children (median age of 4.4 yr) were evaluated twice with each instrument. Results indicate that the Lighthouse test had higher reliability, better visual acuity scores, lower untestability rates, and shorter testing times than the STYCAR.
