The Pediatric Low Vision Chart: A Critical Appraisal.

In search for new and better ways of measuring visual acuity in the pediatric population, several acuity tests have recently been developed. One such test ts the PEDIATRIC LOW VISION TEST CHART designed by Edwin L.Novak, O.D. for Designs for Vision, Inc. It is important that visual acuity measurements with new tests be comparable to those of accepted clinical acuity tests. Snellen is the most frequently used clinical visual acuity test. With the low vision population the most frequently used test is the DISTANCE TEST CHART FOR THE PARTIALLY SIGHTED arranged by William Feinbloom, O.D. for Designs for Vision, Inc. Although Snellen is the most frequently used visual acuity test and an
acceptable equivalent to Landolt rings, it is not the standard of visual acuity tests. However the purpose of this study was to look at the Pediatric Low Vision Chart in relation to two clinically relevant tests, namely Snellen and the Distance Chart for Partially Sighted.
