Ophthalmology is not just a visual science of the eyes allowing us to visualize the world around us. The diagnosis and management of ophthalmic disorders is complex and is dependant on imaging of the eye and brain using sophisticated instrumentation. This atlas encompasses diagnostic radiology and clinical neuro-ophthalmology and hence is a highly effective teaching tool.

The purpose of this atlas is to provide ophthalmologists and other physicians concerned with eye disease with a carefully selected collection of quality illustrations that review the spectrum of diseases commonly seen in neuro-ophthalmic practice.

I am sure that the Atlas of Neuro-Ophthalmology that is based on experience with patients seen at Sankara Nethralaya will play a key role in acquainting the ophthalmologist with neuro-ophthalmic disorders. The photographs are augmented by succinct textual descriptions and useful references that allow deeper investigation into the subject. It is for these reasons that this book may be recommended to all students and practitioners of ophthalmology. I congratulate the authors for their hard work in producing this atlas.

Each section is color coded and the chapters in each section are in alphabetical order for easy cross-referencing and navigation through the book. For every topic, a small number of recent classic reviews have been added. Original images of patients seen in the neuro-ophthalmology department of Sankara Nethralaya constitute this atlas. Selected disorders are illustrated using several different images that present the early and late stages of the condition as well as variations of presentation. I hope that the readers, including neurologists, neurosurgeons and radiologists, apart from ophthalmologists, will benefit from this collection and this text will serve as a useful reference to provide better care for patients. Both students and practitioners are urged to take full advantage of the wealth of outstanding textbooks on neuro-ophthalmology, the Bible of course, being Walsh and Hoyt's Clinical Neuro-Ophthalmology.

Special thanks are due to Dr. Veena Noronha who guided us to choose the best neuroimaging pictures for this book. S.P. Govindarajan, Chidambaram and Santhanam of the medical photographic department carefully took most of these photographs and this book would not have been possible without them. V. Murali and his team of Sukumar, Shankar and Mohan of the multimedia department have scanned and archived the pictures in record time. Credit goes to all the patients who enriched our experience and learning by putting their faith in us and allowing us to record these pictures. We appreciate the secretarial assistance of Beena who helped us archive the images on a regular basis.

We are extremely grateful to all the consultants of Sankara Nethralaya and Dr Deepak Arjundas (Neurologist), Dr Suresh Bapu (Neurosurgeon) and Dr B Chidambaram (Pediatric Neurosurgeon) among other specialists who helped us in the comprehensive management of these cases.

We wish to express our gratitude to Professor Mrs. Nirmala Subramaniam, Dr. Malay Verma, Dr. Bhaskar Srinivasan, Dr. Murali Krishna and Dr. Smriti Chaudhary for their valuable contribution to the second edition of this Atlas.

Our friends and families have supported us and given us extremely useful ideas to improve the book.

This atlas represents Sankara Nethralaya's experience in the practice of clinical neuro-ophthalmology.

Finally, the efforts and cooperation of Jaypee Brothers Medical Publishers (P) Ltd. are gratefully acknowledged.
