Interocular Shift of Visual Attention Enhances Stereopsis and Visual Acuities of Anisometropic Amblyopes beyond the Critical Period of Visual Development: A Novel Approach

Figure 2

An example of the 6-down-2-up staircase paradigm. It started at an opening size of 5 pixels, went up and down in 1 pixel step, and stopped when reaching the 5th reversals along the test procedure. The logarithms of the visual angles at these 5 reversals were averaged to give an estimate of visual acuity at this training. On a 19-inch 16 : 9 screen set at 1366 × 768 resolution, one pixel was equivalent to 160 sec of arc when viewed at 40 cm test distance.
