Abstract


Computerized Freiburg Visual Acuity Test (FrACT version 3.9.3) with 3 different Michelson contrasts (100%, 50% and 3%) was used to evaluate different visual acuity variations of eyes with early ARMD compared to healthy eyes. Results suggest that FrACT might be one of sensitive diagnostic criteria to differentiate healthy eyes from early ARMD as testing by the typical Snellen chart using the Landolt rings (C optotypes) alone is insufficient for the visual function testing and provides limited information about the central vision.
