The three most striking characteristics of the cornea are: a) Its structure or rather its perfectly regular architectonic, by virtue of which it is transparent. b) The absence of vessels, the cornea being nourished by the perilimbic vessels, the endothelial surface in communication with the aqueous humour and the epithelial surface in contact with the pre-corneal film. c) The very slow turnover of the cells, that is to say the keratocytes, with the result that the metabolism of the cornea is very weak. It is this third characteristic which justifies our present investigation. The keratocytes, which are apparently inactive, have in fact a latent activity. They can be activated by central corneal incisions and also by tissue cultures. Under either of those conditions, the keratocytes become very active, develop all the cytoplasmic organites and produce mucopoly saccharides as well as the precursors of the collagen (Fig. 1). In order to study the pathological keratocyte, we chose a storage disease, wherein the catabolism of the mucopolysaccharides is blocked, namely the macular dystrophy of the cornea. We undertook the same investigation both for normal and for pathologi cal corneas and studied the keratocyte 'in situ' and in tissue cultures using various microscopical and histochemical techniques. In macular dystrophy, we investigated also the deteriorations secondary to the changes in the keratocytes.

This outstanding volume in the Essentials in Ophthalmology series presents recent developments in the diagnosis and treatment of corneal disease. Its intention is not to replace the relevant textbooks, but to serve as a bridge between primary and tertiary literature. The superbly structured volume covers a dizzying array of topics including Herpes simplex keratitis; amniotic membrane transplantation for the treatment of corneal ulceration in infectious keratitis; and Chlamydial infection, all three of which are hugely relevant today. All the topics have direct clinical importance and will not only keep ophthalmologists up to date, but will inform them of how to treat their cornea patients with optimal diagnostic and therapeutic procedures.

This third volume, with three supporting editors, broadens its focus on genetic eye research from the Asian to the global scale. New efforts and a new awareness have sparked important discussions on genetic eye research, and new plans are being implemented to identify the genes responsible for numerous eye diseases. The book introduces the latest findings on genetics in eye diseases, gene therapy, and genome-wide association analysis, and the efforts of the Global Eye Genetic Consortium (GEGC). The book’s editors have been instrumental in developing strategies for discovering the new genes involved in many eye diseases. All chapters were written by leading researchers working on eye genetics from the fields of Human Genetics, Ophthalmology, Molecular Biology, Biochemistry, Sensory Sciences, and Clinical Research. Advances in Vision Research, Volume III is a major resource for all researchers, clinicians, clinical researchers, and allied eye health professionals with an interest in eye diseases around the globe.

Strabismus, also referred to as ‘a squint’, is where the eyes point in different directions. It is particularly common in young children, but can occur at any age. One of the eyes may turn in, out, up or down while the other eye looks ahead. This text is a comprehensive guide to paediatric ophthalmology and strabismus for paediatric eye specialists. Divided into two sections, the first part of the book covers paediatric eye examination and vision assessment, and the diagnosis and management of a multitude of ocular disorders including conjunctival inflammatory and allergic disorders, paediatric cataract and uveitis, retinopathy of prematurity, ocular and orbital neoplastic lesions, lid and adnexal anomalies, and many more. The second part of the book covers different types of strabismus and its management, explaining both non-surgical and surgical techniques, and their potential complications. The text also touches upon strabismus in adults. With contributions from world renowned experts in their field, this book is further enhanced by clinical images and figures.
