简要总结
This is an analysis of tests of near vision.
Visual perception testing using a novel program on an interactive three dimensional electronic device:
Autostereoscopic dynamic near games for monocular visual acuity, stereopsis and color are compared with other conventional or similar tests.
详细描述
Subjects with normal vision, exceptional vision, or visual deficits have near vision tested on the PDI Check game and compared to other clinical tests.
Interclass Correlation and Bland Altman analysis utilized for continuous data. Sensitivity and Specificity calculated for defined clinical entities. Subjects are not assigned to either one screening test or another; instead different tests are compared.
