These are important concepts to take into account when establishing a treatment. According to Von Noorden (2002), amblyopia is a vision loss caused by deprivation of vision and/or an abnormal interaction binocular, which can not be detected organic reasons to physical examination of the eye, and where to Where appropriate, is reversible by therapeutic means. Nigel (1998) spoke of amblyopia as the result of a variety of sensory and motor abnormalities, which has multiple causes and effects. The conditions that produce amblyopia pathologies are widely known and are in daily consultation: strabismus, anisometropía, refractive errors, cataracts and other forms of visual deprivation.
