Experimental analysis of amblyopia and strabismus.

In the past few years physiological experiments have brought us a little closer to an understanding of some forms of developmental amblyopia-deficits of visual acuity of central, not retinal, origin, which are not correctable by optical means. While amblyopia has become a catch-all term that covers the symptoms of a multitude of disorders, there are certain stereotyped experimental procedures that invariably lead to gross disturbances in the visual system. In this paper we shall describe a few of these experiments and attempt to relate them to some of the clinical origins of amblyopia in man.
