Amblyopia is the most common form of impairment of visual function affecting one eye, with a prevalence of about 1-5% of the total world population. In this context, non invasive procedures based on visual perceptual learning, i.e., the improvement in visual performance on a variety of simple visual tasks following practice, emerge as particularly promising to rescue discrimination abilities in adult amblyopic subjects. This review will survey recent work regarding the impact of visual perceptual learning on amblyopia, with a special focus on a new experimental model of perceptual learning in the amblyopic rat.
This causes the sound eye to become unfocused and forces the use of the lazy eye. Occlusive Therapy Occlusive therapy involves using a patch over the non-amblyopic eye (the sound eye), forcing the use of the lazy eye. Bangerter foils are another option. The foils, which are made of thin vinyl, are placed over the eye glass lens, covering the non-amblyopic eye. Just like with the patch, this forces the weaker eye to become stronger because you will not be able to see well with the foiled lens.
