A device has been developed that offers many advantages not available with
traditional visual acuity testing methods. The Baylor Video Acuity Tester
(BVAT) produces randomized targets, size selectable at electronic speeds
for testing even in normal ambient room light. Comparisons of the BVAT with
the Project-O-Chart (American Optical Corp, Southbridge, Mass) on 60
subjects yield correlations of .93 and .95. A test-retest correlation of
the BVAT of .88 was found.
