The Baylor Video Acuity Tester.

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.

A semi-automated instrument for determination of acuity threshold.

A device has been constructed that permits rapid, repeatable measures of visual acuity while minimizing many of the patient and examiner errors in subjective acuity testing. The Baylor acuity meter utilizes digital logic circuitry to implement a carefully controlled psychophysical "staircase" testing procedure in a small portable unit. Comparisons of the acuity meter with conventional measurement techniques on 51 subjects yield correlations of +.74 and +.81. A test-retest correlation of +.96 was found.
