Abstract: Amblyopia is a developmental abnormality that results from physiological alterations in the visual cortex and impairs form vision. Based on multimedia, visual perceptual learning was widely applied in amblyopia treatment. Perceptual learning provided an important new method for treating amblyopia both in children and adults, and it reflects alterations of neural responses in the visual pathway. The therapeutic efficacy of perceptual learning was related to age, amblyopic types and degrees, training time and programs closely.
