Abstract

Amblyopia, an anomaly of human vision defined as substandard visual acuity even though any refractive error has been optically neutralized and there is no ocular disease, develops mainly in children who have significant interocular difference in refractive error (anisometropia) or a manifest oculomotor deviation (strabismus). So much attention has been given to acuity issues in amblyopia, such as the acuity cutoff for diagnosis, appropriate acuity optotypes, and how much of the acuity chart to exposed, that it is common to think that acuity is the main, only, or even the fundamental defect in amblyopia.
