This Springer imprint is published by the registered company Springer Nature Switzerland AG The registered company address is: Gewerbestrasse 11, 6330 Cham, Switzerland Preface This book presents the most up-to-date oculoplastic knowledge base in a question and answer format. Multiple choice questions are the most com- monly used assessment and teaching technique, and this question format will continue to assume a greater significance in the era of online exams and virtual consultations. This book is designed to target ophthalmologists at varying professional levels; from residents and fellows to consultants. Whether they are prepar- ing for an exam, sitting for a final degree, pursuing subspecialty training in oculoplasty, or requiring a detailed knowledge base of the subspecialty as they encounter clinical cases, this book provides a comprehensive guide from the very basic principles to the most advanced. The book will also be of special interest for consultant ophthalmologists and university professors organizing and preparing exams. The book follows the same structure of the accompanying textbook “Oculoplastic Surgery—A Practical Guide to Common Disorders.” Section by section, it includes over 1000 classic multiple choice questions as well as 150 high-quality clinical photos and illustrations with a variety of case presentations, clinical scenarios, radiological scans, and pathological speci- mens. The questions are meant to supplement the information provided in the textbook, which is available for further clarification and in-depth study of the various subjects. This supplementary approach and extensive illustra- tive support makes this book series unique in the world of oculoplasty (at present, no high-quality referenced question books are available at interna- tional level). We hope this book becomes a staple on every ophthalmologist’s desk as they pursue the specialty and encounter oculoplasty cases in their practice. Cairo, Egypt Essam A.
