This manual provides an organized reference to aid in management of clinical problems and preparation for board exams. A standardized outline format is used in order to emphasize relevant information and allow rapid retrieval of key points. Each section starts with anatomy and physiology—the essential framework for understanding the basis for the related diseases—and then summarizes specific disease entities in outline format, with major features highlighted. For quick reference over 200 specific disease entities are listed, along with corresponding page numbers, on the inside front cover of the book. Figures have been selected to demonstrate classic findings and to highlight important relationships. The manual covers all material listed in the OKAP Subject Outline published by the AAO.
