Amblyopia is a developmental disorder that affects the spatial vision of one or both eyes in the absence of an obvious organic cause; it is associated with a history of abnormal visual experience during childhood. Subtypes have been defined based on the purported etiology, namely, strabismus (misaligned eyes) and/or anisometropia (unequal refractive error). Here we consider the usefulness of these subclassifications.

弱视的分类和多样性

弱视是一种发育障碍，在没有明显器质性原因的情况下影响一只或两只眼睛的空间视力；它与童年时期的异常视觉体验史有关。亚型已根据所谓的病因定义，即斜视（眼睛未对准）和/或屈光参差（不等屈光不正）。在这里，我们考虑这些子分类的有用性。
