This text serves as both a reference for ophthalmologists and a required text for optometry students. It presents material by diagnostic category, and for each category covers the background information, symptoms, case analysis, and management options. Case studies are included at the end of each chapter to further emphasize application to clinical care. New features to this edition include the revision of several chapters and the addition of three new chapters whose topics cover computers, acquired brain injury and learning problems as they relate to vision disorders. References are updated and study questions are added to the end of each chapter.
