		Amblyopia Risk Factors
Home	Amblyopia is caused by disruptions in normal clarity, or ocular alignment (strabismus) or one or both eyes out of focus (refractive error). These are all called "amblyopia risk factors." Evidence and consensus have resulted in listed levels of the characteristic refractive (H53.02_), strabismic (H53.03_)and deprivational (H53.01_) risk factors that aid diagnosis and validation.
