The iris is a circular, pigmented tissue that separates the anterior chamber of the eye from the posterior chamber. It has a crucial role on controlling the amount of the light entering the eye through its central opening “the pupil". The Iris has multiple important functions that support and provide image clarity on the retina. However, it is a largely neglected part of the eye, compared to the cornea lens, retina, and optic nerve, and has not been focused on in a comprehensive way until now. The Iris: Understanding the Essentials, combines different aspects of scientific information from a variety of fields, such as anatomy, histopathology, molecular biology, electron microscopy and other diagnostic modalities. Each chapter will include pearls and summary points, and this multi-disciplinary approach helps the clinician diagnose and treat the large variety of diseases that affect the iris, with the main emphasize on pigmentary pathological changes that can affect the color of the eye. Written as a reference review book for universities, practicing ophthalmologists, Ophthalmology residents, pharmaceutical companies and diagnostic equipment manufacturing companies this book summarizes the information in an easy-to-use manner to help the reader better understand the iris, iris structure, physiology and function.

The diversity of bearded irises rivals that of any other perennial grown in temperate climates. For some gardeners, they bring back warm memories of a grandparent's garden; for others, they're a cutting-edge plant with a seemingly endless capacity for producing new forms and patterns. As the manager of Rainbow Iris Farm and co-editor of the Bulletin of the American Iris Society, Kelly Norris is the authority on gardening with bearded irises. His introductory chapters offer tips for successful growth, garden design, plant selection, and "creating" new irises. A Guide to Bearded Irises also provides portraits of the most outstanding plants in each of the six recognized categories, from the dainty miniature dwarf bearded irises to the stately tall bearded irises. A resource section lists specialty nurseries, organizations devoted to bearded irises, and public gardens with notable iris collections.
