Book Description
When the eyeball is indented in total darkness, within less than 200 mil liseconds an oval or quarter-moon shaped spot of light is perceived in the part of the visual field corresponding to the indented region of the retina. In the seconds following, this phosphene extends across the whole visual field and alters in structure during further eyeball indentation. It is then seen as irregular large bright spots of light, finely structured moving light grains ('light nebula') and stationary bright stars. Regular geometrical patterns appear only when both eyes are indented simultaneously [1]. When the eyeball deformation is released, part of the retina again lights up for another one or two seconds and curved light lines are seen following the course of the larger retinal vessels (Fig. 1). In the following we will review the history of this phenomenon, which played an important role during the first 2200 years of vision theories and in the development of models to explain normal vision. 2. Pre-Socratic philosophers, Plato and Aristotle Alcmaeon of Croton (6-5th century B. C. ), who was a member of the Pythagoraean sect and one of the founders of Greek medicine, was the first to describe mechanical deformation of the eyeball leading to light sensa tions. According to Aristotle's pupil Theophrast of Eresos, Alcmaeon report ed that 'the eye obviously has fire within,for when the eye is struckfireflashes out' [2, p. 88].

Book Description
This comprehensive atlas is unique in combining information on the embryological development of the human with detailed presentation of the congenital malformations encountered in clinical practice. As a consequence it will not only assist practitioners and trainees in recognizing and evaluating malformations, but also enable them to understand how a malformation has developed and to explain the mystery of congenital malformations to relatives and patients. The book is organized according to anatomic region, with additional chapters on hernias, tumors, lymphogenesis and lymphatic malformations. According to WHO statistics, each year congenital anomalies result in approximately 3.2 million birth defect-related disabilities worldwide. All too often, however, training in embryology is now a neglected area, and medical graduates frequently lack confidence in their knowledge of the field. Clinical Embryology: An Atlas of Congenital Malformations will help to rectify this deficit and to ensure that malformations are comprehended and managed appropriately. It will be of value for postgraduate trainees in pediatric surgery, pediatrics, and neonatology, undergraduate medical students, and general practitioners/family physicians.

Book Description
This book aims to assist ophthalmologists in providing the best possible care for children with congenital cataracts. The entire patient pathway is covered, from preoperative assessment through application of the various surgical techniques to postoperative care and management of complications. Among the topics discussed are new developments in molecular genetics relevant to patient evaluation, intraocular lens power formulas, and the findings of the Infant Aphakia Treatment Study. The surgical section describes anterior capsulotomy, lensectomy, selection of intraocular lens (IOL) power, IOL implantation in the capsular bag, posterior capsulotomy techniques, the use of secondary IOLs and iris-fixated IOLs in children, and surgical management in developing countries. Visual outcomes after surgery are also fully addressed, with chapters on the occurrence of strabismus, nystagmus, and poor stereopsis.
