The causes of amblyopia can be divided into four main categories: monocular strabismus, refractive error, high refractive error, and form deprivation. If a patient has monocular amblyopia, it may be caused by monocular strabismus, refractive aberration, and form deprivation. Once a patient is diagnosed with congenital monocular amblyopia, careful examination of the condition and early treatment will make it possible for the amblyopia to return to normal, which is also a characteristic of amblyopia. If a patient is diagnosed with congenital monocular amblyopia, treatment can be started immediately after diagnosis and can be completely cured.
