Contrast sensitivity assessment of functional amblyopia in humans.
Contrast threshold measurements have extended our perspective of human amblyopia by focusing our attention on the perception of objects larger than the resolution limit. This approach has shown that there are two categories of spatial loss in amblyopia, that anisometropic and strabismic amblyopia have a different neural basis, and that suprathreshold anomalies can occur independent of threshold defects.
