Many large text books are available, which are very complete and up-to-date, but may be quite difficult to use on a day-to-day basis when you are in front of a patient with uveitis and need help to decide what to do. Practical Uveitis: Understanding the Grape is a book designed to tackle this problem and to allow clinicians to make sense of the clinical signs and organise their thinking regarding type of uveitis, severity, investigations that may be helpful and those that may be unnecessary, or even generate confusion, and how best to manage the different presentations. The book starts with the necessary basic concepts and cleverly explores the classification of uveitis as an important element for the following steps. The correct recognition of the site of primary involvement, which can only be defined following thorough examination of the ante- rior and posterior segment, is essential for the elaboration of a differential diagnosis list and for the decisions about what other information will be necessary to achieve the final diagnosis and establish your treatment strategy. Subsequent chapters deal with the different anatomic sites affected with uveitis and cover all the key aspects of the clinical presentations, critical use of tests and many of the pitfalls related to incorrect interpretation of findings and scattered approach to testing. The rationale for the questioning of patients about other general health problems and request of investiga- tions is well explained and will immensely help those with less experience in this field. They also, very clearly, go over the rationale for the introduction of therapy, especially when and how to start and how to monitor and taper. They present a very broad discussion on posterior uveitis, which represents the most worrying form when it comes to visual loss and importantly, they address the issue of the sight-threatening uveitis, expanding on the most common and aggres- sive conditions. There is a very good discussion on vascular involvement, a subject which many times confuses even experienced uveitis specialists. A dedicated chapter to episcleritis and scleritis summarises these important inflammatory conditions, which can, in many cases, be associated with a severe systemic disease that may result in significant health issues if not quickly recognised and managed. The final chapters deal with the use of immunosuppressive therapy and new developments in the management of uveitis. There is a good overview of the various alternatives, the indica- tion for their use and the dangers associated with their use, apart from the always worrying issue of use of drugs in pregnancy. The new alternatives include a good description of the use of biologics, which are becoming increasingly more used. This book is loaded with pearls and the tables and illustrations will undoubtedly be a great asset to all those who want to be able to confront a patient with uveitis with more confidence vii Foreword and will help them structure their thinking and make adequate use of investigations and make a well-balanced assessment of the available information to reach the right decision regarding diagnosis and management. I congratulate the authors on this achievement. This a balanced and clear text on a difficult topic.
