As a degenerative disorder of the eye, keratoconus can cause substantial distortion of vision, with multiple images, streaking, and sensitivity to light all reported by patients. Keratoconus: Recent Advances in Diagnosis and Treatment updates ophthalmologists about the innovations that have occurred within the last decade, discussing the diagnostic imaging techniques that have been developed for keratoconus diagnosis, understanding of how examination techniques are related to the evolution of keratoconus, and how to indicate the different therapeutic tools that have been created for keratoconus over the last several years. Additionally, fundamentals for new diagnostic elements, based on the mathematical, physical and biomechanical data are analyzed in depth for a better understanding of the essential diagnostic steps for the clinician to guide patients towards the most adequate therapeutic tool in the case. Modern keratoplasty techniques, assisted by femtosecond lasers or other devices, are also covered and these techniques, along with the emerging conservative treatments, have added to more precise control of the evolution of the disease.

Confocal microscopy with laser scanning technology yields in-vivo images of ocular and ocular adnexal surfaces that are so brilliant that they rival histology in terms of quality.This unique atlas and textbook demonstrates normal in-vivo anatomy of the cornea, limbus and conjunctiva, quantifies various cellular structures using cell-density calculations and establishes correlations between novel optical sections of various diseases of the ocular surface and clinical findings. Furthermore, it supports the interpretation of novel high-magnification optical sections by comparing corneal and conjunctival imprint cytology with in-vivo images and describes early inflammatory changes in corneal grafts, as well as corneal conjunctivalisation in limbal stem cell deficiency, corneal dystrophies or infections, flap interface and margin characteristics after laser in-situ keratomileusis (LASIK). In addition, it instructs the reader about diagnostic and therapeutic follow-up strategies and provides a brief introduction to applications in other fields such as dentistry and ear, nose and throat surgery.

The desire to teach and the fulfillment attained from teaching have again prompted us to produce a work that we hope is both useful and enlightening to our readers. The field of oculoplastic surgery has grown and evolved to include all aspects of eyelid and facial plastic surgery. Our literature must now reflect the advancements and - rection of our field. Knowledge of anatomy, the basis of all surgery and the root of surgical principles and techniques, supports our ab- ity to deliver the highest quality care to our patients. We have therefore combined text and diagrams and supplemented them with DVD digital video technology to enable those who wish to perform this surgery the best possible instruction and preparation. We hope that our attempts to accomplish this will be rewarded by the use of this material by colleagues and the acknowledgment of our unique and logical progression in the field of eyelid and facial pl- tic surgery. The previous volume in this series covered reconstructive eyelid surgery. This volume presents many aspects of facial cosmetic surgery, including blepharoplasty, endoscopic forehead surgery, rhytidectomy, and other related procedures. Future volumes will pr- ent facets of lacrimal and orbital surgery. Frank A. Nesi, MD vii ACKNOWLEDGMENTS Bringing a book project to fruition is always a complicated process involving many people. It is through their dedication, profession- ism, and team effort that it all comes together.

Optical coherence tomography angiography (OCTA) is a non-invasive technique for imaging the microvasculature of the retina and the choroid. The advent of OCTA has allowed ophthalmologists to identify new pathologies, recognise new syndromes, and organise disorders with new classifications. This atlas provides clinicians with state-of-the-art principles of clinical OCTA imaging, helping them interpret and understand the features of the angiographic images. Following the success of the first edition (9789351528999) published in 2015, this second edition has been fully revised, with all chapters rewritten and new topics added to provide the very latest advances in the field. New knowledge about existing diseases and new disorders are described in depth, and operating principles, clinical applications, and future developments are explained thoroughly by the pioneers of the technology. The first part of the atlas covers the basic principles of OCT angiography, methods and technology, image interpretation, vascular anatomy of the retina, and clinical applications. Part two provides a general update on current research into OCT angiography in various retinal, choroid and anterior chamber disorders. The third and final part of the book describes future clinical applications and implications of next generation devices. This new edition is an invaluable guide for ophthalmologists and trainees for use in everyday practice.

This book is written for retinal specialists and clinicians with a special interest in retinal diseases. It presents a collection of images and brief annotations of the microstructures of both the normal and diseased eye captured on swept source optical coherence tomography. The swept-source OCT is a relatively new form of imaging and is able to capture structures and details which previous generations of OCT machines cannot. This type of imaging represents the forefront in ocular imaging. This second edition includes a new chapter on optic nerve conditions and more cases on eye conditions that were imaged with the SS-OCT. It also showcases the use of swept-source OCT for OCT angiography.

Over the weekend of 21-23 February 1997, a small group gathered in Tallahassee, Florida, at the invitation of Ted Williams, to discuss "photo stasis and related topics." The majority of participants were former students and colleagues of Ted's, but an occasional outsider such as myself was generously included. The papers presented there are collected in this volume. The theory of photo stasis was first outlined in a landmark paper by John Penn and Ted, published in 1986 in Experimental Eye Research. They provided compelling data showing that, in the albino rat eye, levels of rhodopsin, outer-segment length, rhodopsin regeneration rate, and even, perhaps, rhodopsin packing density all depend on the levels of cyclic illumination (12 hours light, 12 hours dark) in which the animal was reared. So, for example, there is fourfold less rhodopsin in a retinal extract derived from an animal reared at 400 lux than in an extract from the retina of an animal reared at 3 lux. Animals reared at intermediate levels of light show intermediate amounts of rhodopsin that are correlated with illumination level. What these data immediately suggested is that the photoreceptor cell can adjust its photon-catching ability in response to the levels of light in which an animal is reared, and they also provided a compelling rationale for outer-segment turnover, a phenomenon discovered 20 years earlier by Richard Young but whose function has remained obscure.
