Cell Biology of the Eye discusses the eye tissues and its role in the investigations on active transport, growth factors, receptors, and differentiation. The book is comprised of articles which discuss corneal proteoglycans; transport of ions and metabolites across the corneal endothelium; the ontogeny and localization of the crystallins in eye lens development and regeneration; the biological-physical basis of lens transparency; the chromatic organization of the retina; and the dopamine neurons in the retina. This treatise will serve as a valuable reference text for graduate and professional students, teachers, researchers, clinicians, and to all in the vision field.

Actions of and interactions among AQPs, CFTR, and ENaC are also of central importance to airway surface liquid (ASL) function and dysfunction, and have been considered with regard to both the etiology and possible treatment of cystic fibrosis (CF) lung disease. Recent data indicated clinical benefit of nebulized hypertonic saline in CF. The proposed mechanism of increased ASL volume relies on purported inhibition of lung AQPs by the ENaC inhibitor amiloride. Sensitive fluorescence methods indicated that amiloride does not inhibit AQP-mediated airway water permeability, indicating the need to identify alternate mechanisms for clinical benefit of hypertonic saline.

This book addresses the issues relating to a wide variety of ocular diseases from which millions of people suffer. Long-term challenges include visual impairment and ocular blindness. Certain ocular diseases are quite rare, whereas others, such as cataracts, age-related macular degeneration (AMD), and glaucoma, are very common, especially in the aging population. A rapid expansion of new technologies in ocular drug delivery and new drug candidates, including biologics, to treat these challenging diseases in the retina and posterior segments of the eye have recently emerged. These approaches are necessary because the eye has many unique barriers to drug delivery. Thus, this timely reference Drug Delivery for the Retina and Posterior Segment Disease compiles and analyzes recent advances in the research and development of drug delivery systems for retina and posterior segment diseases of the eye, with an emphasis on the use of implantable devices, iontophoresis as well as micro- and nanoparticles.

During the past several decades, a significant international research effort has been directed towards understanding the composition and regulation of the preocular tear film. This effort has been motivated by the recognition that the tear film plays a critical role in maintaining corneal and conjunctival integrity, protecting against microbial challenge and preserving visual acuity. In addition, research has been stimulated by the knowledge that alteration or deficiency of the tear film, which occurs in numerous individuals throughout the world, may lead to desiccation of the ocular surface, ulceration and perforation of the cornea, an increased incidence of infectious disease, and potentionally pronounced visual disability and blindness.
