This book describes transdisciplinary management of multiply disabled children with vision problems and presents four theoretical models of visual assessment and three illustrative case studies in a sequence appropriate to the learning process. The first three models are intended to lead to assessment and management of the child and the last to assessment and management of the child's environment. The models are: (1) medical (anatomy, physiology, pathology of the optical and neural visual system); (2) educational (visual perception and learning); (3) developmental (reflexive and voluntary eye movements, relationship between visual and motor processes); and (4) functional (visual components of daily living, assessment of the environment). After an introductory section, Part One presents the theoretical rationale in a discussion of each of the four models as applied to the cases. Part Two describes developmental vision assessment including evolution of the Erhardt Developmental Vision Assessment instrument and models for assessment. Part Three first offers a model for management of visual-motor dysfunction and then applies the principles of assessment to management of each of the three cases. The final chapter offers a summary including a synthesis of models for visual-motor assessment and management. A glossary defines technical terms. References are included with each chapter. (DB)
