The role of contrast sensitivity charts and contrast letter charts in clinical practice

Abstract

Practitioners frequently make clinical decisions based on changes in visual acuity. However, acuity is recognised 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 review 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. This should permit a better understanding of some patients' visual problems, better clinical decision making and a better understanding of studies which report visual performance measurements. Information on currently available equipment and a list of suppliers in Australia is included.

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
