title: Retinal transplants and optic nerve bridges: possible strategies for visual recovery as a result of trauma or disease.
abstract: From the review of the current literature it is quite evident that some exciting prospects are on the horizon which will help to better explain the development and functioning of the visual system. In addition, the new technology of CNS tissue grafting coupled to other newly emerging technologies (i.e., microsurgical, microinjection, and micromanipulative techniques coupled with our knowledge of immunosuppressive methods) will allow for a realistic approach in exploring possible strategies for visual recovery as a result of trauma or disease within the near future. One specific area of research that hopefully will emerge from this new body of knowledge comes from the realization that at the present time there is no effective therapy for practically all types of hereditary retinal degenerative disorders in man. It would seem most appropriate to take advantage of the new neuronal transplantation technology mentioned in this article and the availability of hereditary retinal degeneration models in the hope of developing new methods for a therapeutic approach to this problem. Such an approach could involve replacing the abnormal, absent, and/or lost host retinal cells with tissue from healthy donors by means of a grafting technique with the goal of arresting and/or reversing the disease process. Of course, this is but one example of the many challenges in this area of research which increasingly appear to be within our grasp.
