Leading academic and pharmaceutical researchers and clinicians from many disciplines synthesize and summarize current clinical and basic knowledge concerning abnormal growth of blood vessels in the eye, the cause of major neovascular eye diseases. The authors also identify and assess the most promising approaches with potential for commercial exploitation and discuss the challenges encountered in developing therapeutics for ocular neovascular diseases. Highlights include illuminating chapters on gene therapy and novel drug delivery systems and excellent summaries of the newest therapeutic approaches.

Molecular mechanisms in visual transduction is presently one of the most intensely studied areas in the field of signal transduction research in biological cells. Because the sense of vision plays a primary role in animal biology, and thus has been subject to long evolutionary development, the molecular and cellular mechanisms underlying vision have a high degree of sensitivity and versatility. The aims of visual transduction research are firstto determine which molecules participate, and then to understand how they act in concert to produce the exquisite electrical responses of the photoreceptor cells.Since the 1940s [1] we have known that rod vision begins with the capture of a quantum of energy, a photon, by a visual pigment molecule, rhodopsin. As the function of photon absorption is to convert the visual pigment molecule into a G-protein activating state, the structural details of the visual pigments must beexplained from the perspective of their role in activating their specific G-proteins. Thus, Chapters 1-3 of this Handbook extensively cover the physico-chemical molecular characteristics of the vertebrate rhodopsins. Following photoconversion and G-protein activation, the phototransduction cascade leads to modifications of the population of closed and open ion channels in the photoreceptor plasma membrane, and thereby to the electrical response. The nature of the channels of vertebrate photoreceptors is examined in Chapter 4, and Chapter 5 integrates the present body of knowledge of the activation steps in the cascade into a quantitative framework. Once the phototransduction cascade is activated, it must be subsequently silenced. The various molecular mechanisms participating in inactivation aretreated in Chapters 1-4 and especially Chapter 5. Molecular biology is now an indispensable tool in signal transduction studies. Numerous vertebrate (Chapter 6) and invertebrate (Chapter 7) visual pigments have been characterized and cloned. The genetics and evolutionary aspects of this great subfamily of G-protein activating receptors are intriguing as they present a natural probe for the intimate relationship between structure and function of the visual pigments. Understanding the spectral characteristics from the molecular composition can be expected to

This book provides a comprehensive view of research in lens developmental biology, emphasising technical and molecular breakthroughs. Elucidation of the mechanisms that govern lens development has enabled us to understand how the normal lens forms and how developmental processes are involved in the maintenance of its normal structure, function and growth throughout life. This knowledge is fundamental to our understanding of many lens disorders. The ocular lens has also become a model for understanding the developmental biology of more complex organ systems. In this 2004 book, leading experts in lens cell biology and development discuss lens evolution, induction, morphology, the regulation of the lens cell cycle and fiber cell differentiation, as well as lens regeneration. This book is an authoritative treatment of the subject that will serve as a reference for graduate students and research scientists in developmental biology and in the visual sciences, as well as for ophthalmologists.

Undoubtedly, Drosophila melanogaster, fruit fly, has proved to be one of the most popular invertebrate model organisms, and the work horse for modern day biologists. Drosophila, a highly versatile model with a genetic legacy of more than a century, provides powerful genetic, cellular, biochemical and molecular biology tools to address many questions extending from basic biology to human diseases. One of the most important questions in biology focuses on how does a multi-cellular organism develop from a single-celled embryo. The discovery of the genes responsible for pattern formation has helped refine this question, and led to other questions, such as the role of various genetics and cell biological pathways in regulating the crucial process of pattern formation and growth during organogenesis. Drosophila eye model has been extensively used to study molecular genetic mechanisms involved in patterning and growth. Since the genetic machinery involved in the Drosophila eye is similar to humans, it has been used to model human diseases and homology to eyes in other taxa. This book will discuss molecular genetic mechanisms of pattern formation, mutations in axial patterning, Genetic regulation of growth in Drosophila eye, and more. There have been no titles in the past ten years covering this topic, thus an update is urgently needed.​
