Figure 3.

Positional error in degrees of visual angle across eccentricity for normally sighted (N = 20; black traces) and amblyopic (N = 40; red traces) observers. (A) Standard deviation of rms error, radial error, and tangential error at 56 points per eccentricity per observer, averaged for each group. (B) Standard deviation of rms error, radial error, and tangential error divided by eccentricity at the given location. Calculation of the three types of error in text. Error bars show standard error of the mean, smaller than symbol where not shown.
