Area of Science:

Neuroscience
Ophthalmology
Vision Science

Background:

Individuals with amblyopia exhibit attention deficits, often showing biased attention towards their non-amblyopic eye.
This interocular attention bias is linked to visual suppression, a core characteristic of amblyopia.

Purpose of the Study:

To introduce and evaluate a novel dichoptic attention training method for adults with amblyopia.
To assess the method's efficacy in alleviating visual suppression and reducing interocular attention bias.

Main Methods:

Developed dichoptic attention tasks incorporating searching, counting, and cueing elements.
Presented targets exclusively to the amblyopic eye while distractors were shown to the fellow eye.
Utilized highly visible targets, bypassing contrast sensitivity limitations.

Main Results:

The dichoptic attention training successfully alleviated visual suppression in participants.
Significant improvements in visual functions were observed post-training.
A reduction in the interocular attention bias was a key outcome.

Conclusions:

Dichoptic attention training is a promising therapeutic approach for amblyopia.
This method effectively targets and retrains attention allocation in amblyopic individuals.
The training offers a novel strategy to improve visual function by addressing attention deficits.
