CONTRAST SENSITIVITY TESTS IN CLINICAL PRACTICE

 

Iran University of Medical Sciences

Abstract: Practitioners and optometrists frequently make clinical decisions based on changes in visual acuity. However, acuity is recognized to be only one aspect of visual performance. In recent years, a number of clinical chart‐based tests which measure different aspects of vision based on contrast sensitivity have become available. These tests allow a more subtle investigation of visual problems. In this presentation of currently available contrast sensitivity charts and contrast letter charts, we examine their clinical application and some of the problems which may be encountered in the use of these tests in practice.
