There are many causes of pediatric strabismic amblyopia. In addition to congenital amblyopia, there are four types of amblyopia: strabismic, refractive error, refractive error, and form deprivation. This is due to congenital or insufficient light stimulation entering the eye during the critical period of visual development, which deprives the macula of the eye of the opportunity to form clear images and/or competition between clear and blurred images caused by unequal visual input from both eyes. 1, strabismic amblyopia: children with strabismus, often due to visual disorders (such as two eyes see one thing as two things) and discomfort, in order to eliminate this discomfort, the visual center of the brain actively inhibit the visual impulses transmitted by the strabismus, over time, the formation of pediatric strabismic amblyopia. 2, refractive parallax amblyopia: the refractive parallax of the two eyes of children, the retina formed by the object image size and clarity differences, not easy or can not be integrated into one, the brain’s visual center can only inhibit the refractive error of the larger eye image, and over time, resulting in pediatric strabismic amblyopia. 3, form deprivation amblyopia: when the infant visual function has not yet developed to the perfect or mature stage occurred when the eye disease affecting vision (such as congenital cataract, ptosis, corneal white spots, etc.), obscuring the pupil, so that the light can not fully enter the eye, so that the retina lost the role of receiving normal light stimulation, resulting in functional impairment and pediatric strabismic amblyopia.
