organic amblyopia

A decrease in visual acuity caused by an identifiable anatomic or pathologic abnormality in the visual system, such as retinal disorders, optic nerve anomalies, or visual pathway lesions. It is generally irreversible, even after treating the underlying cause. Organic amblyopia differs from functional amblyopia, which results from conditions like strabismus, anisometropia, or visual deprivation during the critical period of visual development and may be reversible with appropriate treatment.
