Amblyopia is a condition in which there is insufficient effective stimulation of visual cells during visual development due to various reasons such as strabismus, refractive error, congenital cataracts, etc., resulting in lower corrected visual acuity than normal children of the same age, and no retinal or optic nerve abnormalities are seen on general ophthalmic examination, called amblyopia. In children with low visual acuity (below age-standard visual acuity), it is important to be aware of the possibility of amblyopia, especially low vision in one eye, which is often easily overlooked. It is usually detected by examination by a pediatric ophthalmologist. Amblyopia is a direct result of low corrected visual acuity and, if not treated promptly, can cause permanent visual impairment. Also, imbalances in binocular development can lead to loss of binocular fusion and failure to establish stereo vision and depth perception. This has a serious impact on the healthy physical and mental growth of children and adds a burden to families and society.
