PREFACE
Veterinary ophthalmology has no deficiency of textbooks or atlases, and the available titles are all very good. However, Small Animal Ophthalmology Secrets is different from the other textbooks in the field. The format of The Secrets Series® relies on the authors to pose a question that is commonly asked on exams or in the clinic and then follows up with an answer that is founded on years of the authors' experience. The goal of this text is not to be all-inclusive; the standard texts serve that purpose. The format and the content of this text provide key information in a way that will save readers time and energy concerning topics that they need to know.
It is my hope that The Secret Series® will expand to include other veterinary ophthalmology titles, such as large animal species and exotic species, because ophthalmology still turns me on. It has been enjoyable working with my colleagues to complete this text, and their contributions are much appreciated. In addition, we are all indebted to our animal patients, clients, students, interns, residents, and, last but certainly not least, veterinary technicians.
