Psychophysical mechanisms in humans with amblyopia.
This study shows that the loss of contrast sensitivity in the amblyopic eye does not result from abnormal spatial frequency selective channels. Knowledge of the sine-wave sensitivity of the amblyopic eye may allow accurate predictions of the detection threshold for more complex stimuli. More effective amblyopia treatment strategies may be designed when the amblyope's sensitivity to spatial contrast and relative phase are better understood.
