Reliability and Validity of the Melbourne Edge Test and High/Low Contrast Visual Acuity Chart

Abstract

Of all the tests administered, the MET original photographic version and the Pelli-Robson Chart had the highest test-retest reliability for the low vision group. For the soft contact lens group, the H/LCVA original version (low contrast letters, 18% Weber) and the Pelli-Robson Chart had the highest reliability.
