Intact Perceptual Interactions of Interocular Temporal Phase and Contrast Disparities in Amblyopia.

ABSTRACT:

Purpose

Interocular temporal and contrast differences have been applied separately to improve binocular integration and treat amblyopia. However, the extent to which binocular integration in amblyopia can be improved by combining interocular differences in timing and contrast has yet to be tested. We evaluated how these parameters interact in individuals with amblyopia and in normally sighted controls.

Methods

We developed an interocular flicker integration task in which a pair of dichoptic gratings flickered sinusoidally in counterphase (2 hertz [Hz], 90-degree spatial and temporal offset), producing the appearance of motion. We determined the interocular delay required for optimal integration by adding phase delays to the 90-degree phase offset (left or right eye leading,
