This book contains the proceedings of the IX International Symposium on Retinal Degeneration held October 9-14, 2000, in Durango, Colorado. A majority of those who spoke and presented posters at the meeting contributed to this volume. The chapters reflect a major emphasis on molecular genetics of retinal degenerations, particularly in the areas of candidate genes and in cloning and mapping. Significant new animal models are described, as are several studies on macular degeneration. Studies on animal models, both vertebrate and invertebrate, continue to provide important new findings on the mechanisms of photoreceptor degeneration and cell death, as well as the means to retard, prevent, or reverse the degeneration by potential new therapeutic methods, including transplantation, gene therapy, and survival factors. Diagnostic, clinical, cytopathologic, and physiologic aspects of retinal degenerations in human patients are also presented, as are several papers on structural, physiologic, and ageing studies in normal tissues that are important correlates for the study of retinal degenerations.Anderson, Robert E. is the author of 'New Insights into Retinal Degenerative Diseases' with ISBN 9780306466793 and ISBN 0306466791.
