Advances in Understanding Mechanisms and

This volume brings together work from leading researchers in the fields of developmental disorders of binocular vision, strabismus, and both infantile and acquired forms of nystagmus. It contains four sections. The first section, Basic Concepts of Stable Vision and Gaze, deals with psychophysical aspects of infantile forms of nystagmus and the relative contributions of extraocular proprioception and efference (corollary discharge). It also contains an accessible review of current notions of spatial and temporal visual functions and spatial constancy in infantile nystagmus syndrome and latent nystagmus. The second section, New Models and Techniques for Studying Gaze Stability, reviews animal and development models for strabismus, amblyopia, and nystagmus. It also contains novel optical methods for managing the visual consequences of nystagmus and a study of the potential ill effects of video displays on children's response to near viewing. The third section, New Therapies for Congenital Nystagmus, presents basic genetic studies and clinical trials of drug and surgical treatment of those patients with infantile forms of nystagmus. The final section,General Aspects of Normal and Abnormal Gaze Control, pulls together a range of contributions dealing with normal gaze control, infantile nystagmus, and acquired disorders of eye movements, including new treatment measures. This book will be a valuable resource for all scientists and practitioners interested in developmental disorders of vision.
