Data from individual amblyopic eyes compared with the range of sensitivities found in the controls' non-dominant eyes (grey region).

<p>‘Sensitivity’ (y-axis) refers to the ability to detect the blue stimulus against the yellow background. Sensitivity is measured in decibels (dB) and, consistent with standard, white-on-white perimetry, a higher sensitivity indicates better performance. Error bars represent ±1 standard deviation of the mean. All left eyes were mirrored horizontally to allow comparison with the right eyes across the groups. The pale area between the vertical dotted lines (eccentricities +10 to +20 deg) corresponds to the region of the visual fields affected by the physiological blind spot for each participant.
