Thirteen patients who had functional amblyopia associated either causally or coincidentally with organic ocular abnormalities still responded to conventional amblyopia therapy. The presence of separation difficulty or improvement in visual acuity with a neutral density filter helps predict the presence of functional amblyopia in patients with organic abnormalities.
13例功能性弱视患者，其病因与器质性眼部异常有因果关系或同时存在，这些患者对传统弱视治疗仍有反应。存在分离困难或使用中性密度滤光片后视力改善有助于预测患有器质性异常的患者是否存在功能性弱视。
