The external geniculate body has been studied extensively in numerous investigations of the central visual system, but such research has been concerned largely with the anatomy of the fibers and the representation of the retina in the central nervous system. A consideration of the cellular pathology of this structure, particularly with regard to the effect produced by inflammatory, toxic or degenerative processes, was not found in a review of the literature. Since the external geniculate body is directly associated with the function of vision, the study of its cellular pathology reported here has revealed changes of both academic and clinical interest.

MATERIAL AND METHODS OF STUDY  The material from one hundred and forty-one cases of a wide variety of infectious, toxic and degenerative conditions was examined. In most of the cases the external geniculate body was sectioned from one side and stained by the Nissl, fat, myelin sheath, neurofibril and
