ABSTRACT

DEFINITION/OVERVIEW Amblyopia is derived from Greek and means ‘dullness of vision’. Amblyopia is a unilateral or, less commonly, bilateral reduction of bestcorrected visual acuity that cannot be attributed solely to the effect of a structural abnormality of the eye or the posterior visual pathways. It is caused by abnormal visual experience early in life. Ophthalmologic examination of the eye typically reveals no organic abnormality. In most cases it is reversible by therapeutic measures.1
