The topics in this volume explore the etiology, cellular mechanisms, epidemiology, genetics, models and potential therapeutic measures for the blinding diseases of retinitis pigmentosa and age-related macular degeneration. Special focus is highlighted in the areas of Mechanisms of Photoreceptor Degeneration and Cell Death (extremely important because very little is known how or why photoreceptors die in these diseases, despite an abundance of genetic information), Age-Related Macular Degeneration (with several novel approaches to its analysis), Usher Syndrome (the most severe form of retinitis pigmentosa, which includes an early or congenital loss of hearing along with blindness), and Gene Therapy. In addition, the section on Basic Science Related to Retinal Degeneration is particularly strong with several laboratories reporting on new discoveries in the area of outer segment phagocytosis, a key component of photoreceptor-retinal pigment epithelial cell interactions in normal and degenerating retinas.

Zur Anwendung bei zu Akne neigender Haut

For centuries, humans have tried to explain the complex process of vision and find effective treatments for eye diseases. Perhaps the oldest surviving record of ancient ophthalmic practices is the Babylonian code of Hammurabi that over 4000 years ago, mentioned fees for eye surgery-and penalties for unsuccessful operations that led to loss of the eye. Babylonian medicine was controlled by priests who directed the work of skilled surgeons. The earliest records of Egyptian medicine date from almost the same time. The Ebers Papyrus, dating back to more than 3500 years ago is a superbly preserved document in which a section outlines a relatively advanced system of diagnosis and treatment of various ocular pathologies. The text reveals that ancient Greek and Egyptian physicians prescribed liver juice for night blindness. This was obtained from roasted and crushed ox liver. We now know that their prescription contained a remarkable amount of vitamin A. It was only within the last century, however, that we have recognized the importance of vitamin A to the function of photoreceptors and visual acuity and that its deficiency can result in night blindness. Egyptian ophthalmological practices were held in high esteem in the ancient world and so were their medical institutes, called peri-ankh, which existed since the first dynasty. Herodotus, the fifth century BC Greek historian, comments on the specialization of the physicians: Each physician treats just one disease.

During the last few years, an explosion of infonnation has come from human genetics and molecular and cell biological studies as to the genetic basis for a number of fonns of inherited retinal degenerations. These disorders have plagued mankind for millennia because they take from otherwise healthy individuals the precious gift of sight. The fundamental advances in recent years have identified a number of genes involved in the groups of diseases which hopefully will lead to discoveries that may, in the not too distant future, allow the prevention and possible cure of some of these blinding eye disorders. To foster a forum for discussions of studies on degenerative retinal disorders, we convened a symposium on retinal degenerations in 1984, at the VIth International Congress of Eye Research Meeting, held in Alicante, Spain. Because of the success of this meeting and the subsequent publication, we have since organized a series of biennial satellite meetings on retinal degenerations for the ISER congresses held in Nagoya, Japan (1986), San Francisco (1988) and Helsinki (1990). Each of these satellite symposium on retinal degenerations was accompanied by a published proceedings volume. This volume is the fifth in this series and contains the proceedings of the Sardinia Symposium on Retinal Degeneration held September 15-20, 1992, as a satellite meeting of the 10th International Congress of Eye Research.

Contains the proceedings of the XVI International Symposium on Retinal Degeneration (RD2014), to be held July 13-18, 2014 at the Asilomar Conference Center in Pacific Grove, California. A majority of those who will speak and present posters at the meeting will contribute to this volume. The Symposium addresses the blinding diseases of inherited retinal degenerations, which have no effective treatments and age-related macular degeneration, which has no cures, despite the fact that it is an epidemic among the elderly, with 1 in 3-4 affected by the age of 75. The RD2014 Symposium will focus on the exciting new developments aimed at understanding these diseases and providing therapies for them. The volume will present representative state-of-the-art research in almost all areas of retinal degenerations, ranging from cytopathologic, physiologic, diagnostic and clinical aspects; animal models; mechanisms of cell death; molecular genetics; and developing potential therapeutic measures such as gene therapy and neuroprotective agents for potential pharmaceutical therapy; and several sight restoration approaches, including optogenetics. While advances in these areas of retinal degenerations will be included, several new topics either were in their infancy or did not exist at the time of the last RD Symposium, RD2012. These include many new developments in sight restoration using optogenetics, retinal or RPE cell transplantation, stem cell approaches and visual prosthetic devices. In addition, major advances will be presented in other basic mechanisms in age-related macular degeneration, several new aspects of gene and antioxidant therapy and revolutionary new imaging and functional testing that will have a huge impact on the diagnosis and following the course of retinal degenerations, as well as to provide new quantitative endpoints for clinical trials. The retina is an approachable part of the central nervous system (CNS), and there is a major interest in neuroprotective and gene therapy for CNS diseases and neurodegenerations, in general. It should be noted that with successful and exciting initial clinical trials in neuroprotective and gene therapy, including the restoration of sight in blind children, the retinal degeneration therapies are leading the way towards new therapeutic measures for neurodegenerations of the CNS. Many of the successes recently reported in these areas of retinal degeneration sprang from collaborations established at previous RD Symposia, and many of those will be reported at the RD2014 meeting and included.

The blinding diseases of inherited retinal degenerations have no treatments, and age-related macular degeneration has no cures, despite the fact that it is an epidemic among the elderly, with 1 in 3-4 affected by the age of 70. The RD Symposium will focus on the exciting new developments aimed at understanding these diseases and providing therapies for them. Since most major scientists in the field of retinal degenerations attend the biennial RD Symposia, they are known by most as the best and most important meetings in the field. The volume will present representative state-of-the-art research in almost all areas of retinal degenerations, ranging from cytopathologic, physiologic, diagnostic and clinical aspects; animal models; mechanisms of cell death; candidate genes, cloning, mapping and other aspects of molecular genetics; and developing potential therapeutic measures such as gene therapy and neuroprotective agents for potential pharmaceutical therapy. While advances in these areas of retinal degenerations will be described, there will be many new topics that either were in their infancy or did not exist at the time of the last RD Symposium, RD2014. These include the role of inflammation and immunity, as well as other basic mechanisms, in age-related macular degeneration, several new aspects of gene therapy, and revolutionary new imaging and functional testing that will have a huge impact on the diagnosis and following the course of retinal degenerations, as well as to provide new quantitative endpoints for clinical trials. The retina is an approachable part of the central nervous system (CNS), and there is a major interest in neuroprotective and gene therapy for CNS diseases and neurodegenerations, in general. It should be noted that with successful and exciting initial clinical trials in neuroprotective and gene therapy, including the restoration of sight in blind children, the retinal degeneration therapies are leading the way towards new therapeutic measures for neurodegenerations of the CNS. Many of the successes recently reported in these areas of retinal degeneration sprang from collaborations established at previous RD Symposia, and many of those will be reported at the RD2018 meeting and included in the proposed volume. We anticipate the excitement of those working in the field and those afflicted with retinal degenerations will be reflected in the volume.
