Abstract

The results of injuries in general are very various, and often most complex and obscure. It requires a broad acquaintance and great familiarity with the multiformity of contusions, punctures, lacera. tions, fractures, incisions, and concussions which may be inflicted upon the different parts and structures of the human body, in order to truly estimate their effects, and to direct and carry out the proper treatment. Permit me, therefore, to introduce for discus sion at this time a subject that is not new, but that will profitably bear reconsideration, especially in the light of certain researches that have recently been made in the anatomy, physiology, and path ology of the central nervous system, viz., that class of injuries that may affect vision.2 2. It will not be in keeping with the brevity at which I aim to introduce in this paper illustrative cases, although I would be glad to do so. Those injuries which may affect vision may do so directly or indirectly; immediately or after the expiration of a period of time; temporarily or permanently. Directly, an injury usually affects vision by implicating the eye ball or its muscles. It may, however, involve the optic nerve, and even the visual path within the cranium, viz., the optic tract and the optic fibers within the basal ganglia, internal capsule, and radiations of Gratiolet " in the white substance of the brain, and, also, the visual center in the cortex of the occipital lobe. Concus sions, contusions, and hemorrhages may produce the lesions, or they may arise less remotely by lacerations, cuts, and pressure directly inflicted by the missile, foreign substance, or displaced bone...
