Assessment of techniques for measuring contrast sensitivity in children.
Contrast sensitivity was measured in 10 children aged from 3 to 11 years using 4 psychophysical techniques in order to establish the best method of measurement for clinical use. Of the four methods, staircase, ascending continuous, modified Von Bekesy and two-alternate forced-choice, the staircase was selected as the most appropriate clinical technique and monocular contrast sensitivity functions of normal children were measured.
