J.P.C. de Weerd Evoked potentials are the electrical voltage fluctuations which can be recorded from parts of the nervous system in response to stimulation of sensory modalities. One may distinguish between evoked potentials from the peripheral and the central nervous system. For the latter type a further subdivision can be made into spinal, brainstem, and cortical evoked potentials, according to the (assumed) structures from which the responses derive. Another possible subdivision can be made with respect to the specific sensory ffiodality which is stimulated. Accordingly, one has auditory, somatosensory, visual, gustatory and olfactory evoked potentials. At the present time, the former three types of evoked potentials are the ones that are commonly measured in diagnostic procedures. Yhe corresponding sensory systems are relatively easy to stimulate, for example by means of an acoustic click, abrief electrical shock or a reversing light pattern. In contrast, stimulation of the olfactory and gustatory systems has proven to be technically and physiologically difficult and research in these areas is still in an early stage.

When in the early 60s echography was introduced into the field of ophthalmol ogy, very few ophthalmologists realized the enormous potential of this procedure, the fundamental impact it would have on our branch of medicine or the innovations it would spawn. From its hesitant beginnings, echography has led to revolution in the field of ophthalmology and to our way of examining, treating and monitoring patients affected by eye disorders. This technique has brought untold benefits to patients worldwide. A crucial element in fostering the advance of the application of ultrasound in ophthalmology has been and is the biannual conference of the Societas Internationalis pro Diagnostica Ultrasonica in Ophthalmologia (SIDUO), and incidentally, the Latin name reflects the wish of the founding members that SIDUO be truly international, and even though the instruments and apparatus used in the discipline are highly innovative, the underlying philosophy is one that traces back to Hippocrates, i.e., the healing of man and the improvement of man's quality of life. The first SIDUO conference was held in 1964 in Berlin.

To create a forum for scientists and clinicians interested in degenerative retinal diseases, we began in 1984 to organize a biennial symposium on Retinal Degeneration as a satellite meeting of the International Congress of Eye Research. The timing and varying location of these meetings provides an important assembly for investigators from throughout the world to convene for presentation of their new findings on the causes and potential therapies for degenerative retinal disorders. The VIII International Symposium on Retinal Degeneration was held from July 28-25, 1998, at the Hotel Vier Jahreszeiten in Schluchsee, a small town in the Black Forest of southwestern Germany. Most of the participants in this meeting contributed to this volume, and we are appreciative of the efforts of each author in making this publication possible. The research presented at the meeting, and described in this proceedings volume, reflects a strong emphasis on the molecular genetic approach to understa- ing these disorders. Several of the papers provide important new insights into the mechanism of photoreceptor degeneration and cell death. A number of the studies are targeted at retarding or reversing the degeneration process. Included for the first time are presentations from all the principal laboratories involved in the field of visual prostheses-implant (chip) technology-in which investigations are targeted at restoring vision in eyes that have lost photoreceptor cells. A variety of diagnostic, clinical, histopathological, and physiological assessments of retinal degeneration in patients are also included.
This book provides a visual overview of how to master ultrasonography and ultrasound biomicroscopy techniques. Updated ultrasonic information is included in a simple brief way, featuring didactic points, with a variety of documented scans and illustrated lines underneath for more clarification. Each pathology is accompanied with several scans of different findings to give more information of distinct detections. Ophthalmic Ultrasonography and Ultrasound Biomicroscopy: A Clinical Guide examines many clinical complexities with possible solutions when performing and interpreting ultrasound while also breaking down information for easier intake. The clinical cases are from a specialist eye hospital where many complicated cases are treated, giving a unique insight for the reader to understand treatment for a variety of cases. The book also emphasises the importance of everyday cases with further explanation whilst utilising a diversity of pictures and labels.
The Role of Membrane Receptor Lateral Movement in Signal Transduction.
Patients aftlicted with thyroid eye disease or Graves' ophthamopathy (GO) may experience not only pain and visual loss, but also disfigurement. Full understanding of pathogenesis has been elusive, and treatment modalities are imperfect. As with other conditions, more effective intervention will follow only after a better understanding of pathogenesis is reached. The goal of this volume is to give an overview by leaders in the field of the present state of the art both in pathogenesis and clinical aspects of GO. Much attention has been directed towards determining which cells within the orbit are targets of the autoimmune process, and how these and other cells might participate in the local inflammatory process. It is now generally agreed that orbital fibroblasts, preadipocyte fibroblasts, and adipocytes are the targeted and activated cells in GO and that full-length TSH receptor (TSHr) is expressed in these cells. Further, there is growing consensus that this receptor is up-regulated in the orbit in GO, residing primarily in newly differentiated adipocytes. However, it is also evident, given a sufficiently sensitive assay, that TSHr is detectable in fibroblasts and adipocytes from the normal orbit and other anatomic sites, as well. It will be important to determine whether the observed increase in orbital TSHr expression itself initiates the orbital autoimmune process. Also to be decided is whether orbital lymphocytes from GO patients specifically recognize this receptor, and what factor or factors unique to Graves' dIsease might stimulate TSHr expression in orbital cells.
On behalf of the editorial board and the organizing committee of the 4th congress of the International Society of Ocular Toxicology (I SOT), held in AnnecyNeyrier du Lac, France, October 9 -13, 1994, we are pleased to present to the ocular toxicology community this indexed volume of our congress proceedings. The 4th congress was designed primarily to facilitate and update the knowledge in ocular electrophysiology and ocular pharmacokinetics, in both the clinical and preclinical aspects. The outcome of this 4th congress, established in this volume, is a useful contribution to the meth odology in both fields and will hopefully assist in the evaluation and interpretation of ocular findings recorded in animal studies on drugs and other chemicals, in order to protect human health. Undoubtedly, work on the mechanisms of ocular toxicology in the process of pharmaceutical development must continue and these proceedings, embodying the presented papers, will add to the data base. The editors, the congress organizing committee and the members of the International Society of Ocular Toxicology thank the speakers who gave their time, knowledge, and expertise to assist us in this project. The following manuscripts contain the main substance of each of the platform presentations and, in some cases, much more. Moreover, our thanks go to all the participants coming from a range of background- regulatory, academic and industrial -for their attention and excellent contributions during the discussion."
In 1984, we organized a two-day symposium on retinal degenerations as part of the biennial meeting of the VI International Society for Eye Research, held in Alicante, Spain. The success of this first meeting led to the second held, two years later in Sendai, Japan, organized as a satellite of the VII ISER. We were fortunate that these meetings began at a time of vigorous research activity in the area of retinal degenerations, thanks to the financial support of the Retinitis Pigmentosa Foundation and the strong encouragement of its scientific director, Dr. Alan Laties. Significant advances were made so that every two years scientists were eager to meet to share their findings. The programs included presentations by both basic and clinical researchers with ample time for informal discussions in a relaxed atmos phere. Many investigators met for the first time at these symposia and a number of fruitful collaborations were established. This book contains the proceedings of the VI International Symposium on Retinal Degenerations held November 6-10, 1994, in Jerusalem. As with the other meetings, some new areas were covered. One session was devoted to apoptosis, an important process involved in cell death in inherited retinal degenerations. Another session was on invertebrate photoreceptors, where numerous mutations have now been identified that lead to altered function or degeneration of the retina. All participants were invited to submit chapters and most complied. We thank them for their contributions."
From the perspective of the investigator, Graves' disease is a fascinating disorder with unique features and opportunities for study. The discovery in 1956 that Graves' disease was caused by a humoral factor, later shown to be an antibody to the TSH receptor, was a triumph for modern investigative medicine. Rapid progress is now being made in (i) understanding the molecular interaction between autoantibodies and the TSH receptor, (ii) identifying the genes that contribute to the predisposition to disease, (iii) developing an animal model of Graves' disease, and (iv) identifying the long-sought orbital antigen in ophthalmopathy. From the clinical standpoint, although Graves' disease is eminently treatable, there is no definitive cure. None of the therapeutic options are ideal. It is hoped that rapid progress in understanding the pathogenesis of the disease will lead to the ultimate goal of some form of immunotherapy that will make antithyroid drugs, radioiodine and thyroidectomy obsolete. The chapters in Graves' Disease: Pathogenesis and Treatment represent the viewpoints of many prominent clinicians and investigators working in the field. The editors are grateful for their contributions which cover an unusually comprehensive compendium of subjects relating to the disease.
Today, ophthalmic pathology deals more and more with pathogenesis using highly sophisticated techniques. In recent decades, it has ex panded to such an extent that it now fills several volumes of a modern comprehensive atlas or textbook. Black and white prints of the macroscopic appearance of dissected eyes are standard in modern textbooks. Color photographs, although providing more visual infor mation and a better insight into the sometimes complex disease pro cesses of the eye, are however costly. Nevertheless, many ophthalmo logic colleagues expressed their desire to have me prepare such an atlas. It is not intended to replace one of the textbooks in this field but rather to supplement existing texts and to stimulate clinical and diagnostic thinking. Hence it should be used in conjunction with textbooks on anatomy and ocular pathology. The reader will find references on the different subjects in the excellent modern textbooks listed below. Diagnosis and treatment in ophthalmology is to a great extent based on morphologic examination. Clinical ophthalmologists have available such excellent tools as the slit-lamp, the gonioscope, and the ophthalmoscope to study and document ocular disease in vivo under high magnification. Both external eye structures and transpar ent ocular structures can be observed better in vivo than in the pathol ogy laboratory. Therefore the pathology of these is only presented in conditions in which direct visualization is normally difficult."
Glaucoma Update VI comprises the latest progress in scientific glaucomatology. Forty-one articles of highly reputed experts in the field cover the genetics and other risk factors of the disease and provide new insights into the pathophysiology of blood flow, visual function and optic neuropathy in glaucoma. Special emphasis is placed on innovative treatment options, both medical and surgical.
It will be difficult to find an ophthalmic surgeon who will gladly do his work entirely without viscoelastics. Within just a few years this group of substances has enlarged the field of ophthalmic surgery enormously. Many procedures have be come safer and simpler and other techniques could only be developed because of the availability of visco elastics. Especially cataract surgery and implantation of intraocular lenses have benefitted. Implantation of an intraocular lens can be per formed much more reliably into the capsular bag without endangering the posterior capsule. Implantation of foldable lenses would be almost impossible without visco elastics. However, other surgical maneuvers also necessitate visco elastics, especially when the anterior chamber must be maintained, the corneal endothelium must be protected and delicate tissues must be manipulated. A cor neal transplant can be sutured safely into the recipient corneal ring using visco elastics. Even in glaucoma surgery, visco elastics gain importance as they are being used in trabeculectomy or in deep sclerectomy with additional viscocana lostomy. But which substance is best for which purpose? Just as much as a basic phar macological knowledge is necessary for a rational use of drugs, in-depth know ledge of physicochemical properties and objective investigations are prerequi sites for a logical selection of visco elastics from an ever increasing number of available substances.

This is at once a review and a summary of the tremendous advances that have been made in recent years on the effect of attention on visual perception. This broad-ranging volume will appeal to vision scientists as well as to those involved in using visual processes in computer animations, display design or the sensory systems of machines. Physiologists and neuroscientists interested in any aspect of sensory or motor processes will also find it very useful.
Intracranial injury, caused by a transorbital penetrating object, is a neglected topic in neurosurgery. With few exceptions, only occasional publications, often containing merely case histories, are present in the literature. Through a perusal of the world literature - for the first time - the author has collected and combined all available and relevant information, trying to give a thorough description of this rare, but extremely dangerous injury. This book is a major and definitive contribution to neurosurgery, but is also of importance to ophthalmology, neurology, traumatology, neuro-radiology and pediatrics.
This is the first comprehensive text on the history of color theories since Halbertsma's book of 1947. Color is discussed in close connection with the evolution of ideas of light and vision. The book has chapters on the ancient Greek ideas of vision and color; on the contributions of Arabic science; on the Scientific Revolution from Kepler to Newton; on the early history of the three-color hypothesis; on the trichromatic theory and defective color vision; and on Goethe's, Schopenhauer's and Hering's theories. New understanding of the structure and functions of the retina and the brain finally results in the modern science of color vision. A History of Color has been written for ophthalmologists, optometrists and others who are interested in visual science and its history. The book requires no specialized knowledge. |
