Written by a multi-disciplinary team from the Department of Ophthalmology at the National University Health System in Singapore, the 2nd Edition of Essentials of Ophthalmology: For Medical School and Beyond is a significantly improved version of the much appreciated first edition. The original purpose of this publication remains the same: to serve as a comprehensive reference book for medical undergraduates, residents, and family physicians, who are often the first line of eye care providers in the community.The book is designed to cover all the Entrusted Professional Activities (EPAs) mandated by the Undergraduate Ophthalmology curriculum in Singapore. The chapters have been thoroughly revised, with the addition of new clinical images and expanded coverage of ophthalmic conditions. This edition also introduces three new chapters: one on basic electrophysiology, which aims to clarify the complex electrical responses of the retina and visual pathway to light; another on biostatistics, intended to inspire students to engage in basic research; and a comprehensive chapter on the End of Posting Test (EOPT), featuring scenario-based questions and answers from every subspecialty in ophthalmology, which will be invaluable for students preparing for assessments.The original point format, including 'learning objectives' and 'take-home messages,' has been preserved to facilitate easy reading and quick learning. With nearly 250 high-resolution clinical images, this book now serves as an even more practical guide to studying ocular diseases, along with the basic methods of investigation and treatment where applicable.Written by experts from every sub-specialty for undergraduate medical students, the book is concise and well-illustrated with high resolution clinical pictures, and distinguished by its point format and inclusion of learning objectives and take-home messages.
