This volume on Visual Psychophysics documents the current status of research aimed toward understanding the intricacies of the visual mechanism and its laws of operation in intact human perceivers. As can be seen from the list of contributors, the problems of vision engage the interest and experimental ingenuity of investi gators from a variety of disciplines. Thus we find authors affiliated with depart ments of biology, medical and physiological physics, ophthalmology, physics, physiology and anatomy, psychology, laboratories of neurophysiology, medical clinics, schools of optometry, visual and othcr types of research institutes. A continuing interplay between psychophysical studies and physiological work is everywhere evident. As more information about the physiological basis of vision accumulates, and new studies and analyses of receptor photochemistry and the neurophysiology of retina and brain appear, psychophysical studies of the intact organism become more sharply focused, sometimes more complex, and often more specialized. Technological advances have increased the variety and precision of the stimulus controls, and advances in measurement techniques have reopened old problems and stimulated the investigation of new ones. In some cases, new concepts are being drawn in to help further our under standing of the laws by which the visual mechanism operates; in other cases, ideas enunciated long ago have been reevaluated, developed more fully, and reified in terms of converging evidence from both psychophysical experiments and unit recordings from visual cells.

Now updated and expanded to cover the latest technologies, this full-color text on clinical refraction uses an easy-to-read format to give optometry students and practitioners all the important information they need. Also covers a wide range of other aspects of the eye exam, including anterior and posterior segment evaluations, contact lens, ocular pharmacology, and visual field analysis. Four new chapters cover wavefront-guided refraction, optical correction with refractive surgeries, prosthetic devices, and patients with ocular pathology. - Offer precise, step-by-step how-to's for performing all of the most effective refractive techniques. - Presents individualized refractive approaches for the full range of patients, including special patient populations. - Contriubtors are internationally recognized, leading authorities in the field. - New full-color design with full-color images throughout. - Completely updated and expanded to include current technologies. - A new chapter on Optical Correction with Refractive Surgeries, including keratoplasty, traditional refractive surgeries (e.g. LASIK and PRK), crystalline lens extraction with and without pseudophakia, the new presbyopic surgery, etc. - A new chapter on Wavefront Guided Refraction provides information on the advantages and limitations the Hartmann-Shack Method for objective refraction plus aberrometry and the refraction and the use of in the correction of the eye with spectacles, contact lenses, and refractive surgery. - A new chapter on Patients with Ocular Pathology reflects the most current knowledge of patients with ocular pathologies. - Provides information on Optical Correction with Prosthetic Devices, including corneal onlays, stromal implants, phakic intraocular lenses, etc. - Includes new chapters and/or discussions on such topics as: Aberrations of the Eye, Refractive Consequences of Eye Pathology, Diagnosis and Treatment of Dry Eye, Diagnosis of Pathology of the Anterior Segment, Diagnosis of Glaucoma, and Diagnosis of Pathology of the Posterior Segment. - Visual Acuity chapter expanded to include the effect of refractive error on visual acuity and statistics on how much of a change in visual acuity is significant. - Objective Refraction, Corneal Topography, and Visual Field Analysis chapters include the addition of new electro-optical and computer techniques and equipment. - Chapters on Multifocal Spectacle Lenses and Contact Lenses now cover newer progressive addition lenses and contact lenses that are now on the market. - Electrodiagnosis chapter revised to take a more clinical approach.

Congenital glaucoma is a complex problem, which has been a frequent cause of blindness in the past. Over the past decades, the prognosis of congenital glaucoma has completely changed. Surgical results are very good and enable these children to integrate entirely as adults in society. Based on the authors’ accumulated experience of more than 50 years and 860 cases operated for congenital glaucoma, this well-structured and lavishly illustrated textbook-atlas covers all aspects of congenital and infantile glaucoma, such as the original method for examining new-borns under general anaesthesia in the slit-lamp, the signs and symptoms of the disease and the differential diagnosis, the role and importance of the echometry value for early diagnosis, the gonioscopy results and the three types of congenital glaucomas (pure, refractory and late) and the type of surgery to be performed in each case with the evaluation of follow-up long-term results. Written by renowned international experts of the field, this book will become the golden standard in the field of Pediatric and Congenital Glaucomas.
