Amblyopia.

Although the studies of amblyopia, especially the amblyopiogenic factors, symptomatology, terminology, and classification have been well clarified both in clinical aspects and in animal models, detailed pathophysiological mechanisms and psychophysical symptoms have still remained nuclear in many respects. As von Noorden (Helveston et al., Symposium on strabismus: Transactions of the New Orleans Academy of Ophthalmology, St. Louis: CV Mosby; 1978: 1-9) mentioned, the complexity of the amblyopia syndrome is symbolized as an iceberg and reduced visual acuity is the most tangible of many disturbances of visual function. This past year, several articles on amblyopia were published in many journals, and the authors review these articles which are grossly classified into three categories: 1) pathophysiology; 2) symptoms, examinations and diagnosis; and 3) treatment.
