چکیده
Purpose: To develop stereoacuity test using a high-resolution 3D monitor and examined the effects of the monitor on the measured stereoacuity. Methods: We conducted stereoacuity test using a high-resolution 3D monitor. This 3D monitor can show parallax of 27 s (crossed) at the minimum at measurement distance 40 cm, and circularly polarized glasses were used for binocular separation. Titmus stereo test (TST) and TNO stereotest (TNO) were performed for comparison. Results: The high-resolution 3D monitor, TST, and TNO average stereoacuity values were 35.0 ± 18.4, 50.0 ± 10.4, and 91.3 ± 53.0s, respectively. The stereoacuity value of the 3D monitor was significantly lower than that of the TST and TNO tests (p < 0.02, p < 0.0002, respectively). The stereoacuity value of the TST test was significantly lower than that of the TNO test (p = 0.002). Conclusion: We consider stereoacuity test using 3D monitor which can show various images is effective.

New Stereoacuity Test Using a 3-Dimensional Display System in Children
The previously developed 3-dimensional (3D) display stereoacuity tests were validated only at distance. We developed a new stereoacuity test using a 3D display that works both at near and distance and evaluated its validity in children with and without strabismus. Sixty children (age range, 6 to 18 years) with variable ranges of stereoacuity were included. Side-by-side randot images of 4 differ...
