OCT is a relatively new imaging technique that is becoming increasingly popular among ophthalmologists in both private and academic settings. Imaging has been a slow moving area in ophthalmology for some time, but now OCT is providing another, more detailed source of demonstrable change in the eye, in diagnostic, therapeutic or post-surgical setting. OCT and ultrasound both measure advancing disease states and post surgical healing. The difference is that OCT shows more subtle changes, particularly post-surgically.

Rapid or even dramatic progress has been made in the field of AMD over recent years, leading to a constant revision of basic concepts. A wide range of fundus imaging modalities are now available, and this book explains the respective value of each technique. The information provided by OCT is presented logically by comparison with plain films, autofluorescence, fluorescein angiography, or indocyanine green angiography. Meticulous biomicroscopic examination of macular changes and the essential value of fluorescein angiography for the detection of anatomical alterations of the macula and for precise evaluation of lesions and their course by indocyanine green angiography have naturally led the author Gabriel Coscas to analyze the new data provided by OCT.

High-speed anterior segment optical coherence tomography (OCT) offers a non-contact method for high resolution cross-sectional and three-dimensional imaging of the cornea and the anterior segment of the eye. As the first text completely devoted to this topic, Anterior Segment Optical Coherence Tomography comprehensively explains both the scientific principles and the clinical applications of this exciting and advancing technology. Anterior Segment Optical Coherence Tomography enhances surgical planning and postoperative care for a variety of anterior segment applications by expertly explaining how abnormalities in the anterior chamber angle, cornea, iris, and lens can be identified and evaluated using the Visante OCT™. Inside Anterior Segment Optical Coherence Tomography, Dr. Roger Steinert and Dr. David Huang, along with 22 of the field’s leading professionals, provide a wealth of useful clinical and physiological material about this new diagnostic imaging technique. Valuable images are included to assist in the pre- and postoperative assessment of various anterior segment disorders. Additionally, this unique resource contains detailed information on biometric measurements to enhance diagnostic capability. On the leading edge of anterior segment imaging: • Mapping of corneal thickness and keratoconus evaluation • Measurement of LASIK flap and stromal bed thickness • Visualization and measurement of anterior chamber angle and diagnosis of narrow angle glaucoma • Measuring the dimensions of the anterior chamber and assessing the fit of intraocular lens implants • Visualizing and measuring the results of corneal implants and lamellar procedures • Imaging through corneal opacity to see internal eye structures With the increase in popularity of anterior chamber imaging, and anterior segment OCT proving to be the best tool for high resolution biometry, Anterior Segment Optical Coherence Tomography is a must-have for anterior segment, refractive, cornea, and glaucoma surgeons.

The emergence of Optical Coherence Tomography (OCT) in recent years has revolutionized the way we see the retina. Providing, in real time, high-resolution cross-sectional images of the macula that are very similar to obtaining in vivo histopathological specimens, OCT represents a major advance in the diagnostics of retinal disease. The excitement of working with this new tool has been dampened by the non-availability of any standard textbook on the subject and meant that every new finding on the OCT saw us rushing to the library almost on a daily basis to locate any published reports on the subject. Until now. Containing nearly 900 scans of both normal and diseased appearances, most in full color, Atlas of Optical Coherence Tomography of Macular Diseases covers how to use Stratus OCT for diagnosing various macular disorders, identifying correct therapeutic approaches and monitoring the responses to therapies and interventions. The authors provide brief case summaries, fundus photographs, fluorescein angiography, and the OCT images and the follow up images. They discuss OCT applications for diagnosis, management, and follow-up in diabetic macular edema, macular hole, taut posterior hyaloid membrane, vitreofoveal traction, idiopathic central serous chorioretinoplasty, submacular pathology, and more.

The Spectral Domain Optical Coherence Tomography (OCT) gave us so much new facts about retinal disease that we wonder how we ever practiced as Vitreoretinal Consultants all these years. Topcon 2000 machine along with its upgraded software landed on our doorstep. With its improved and enhanced speed of 27,000 A scans/sec, improved software algorithms and additional facilities for anterior segment imaging. In this second edition highlight all these features and added newer chapters in keeping with the newer features. Images from the previous edition have been updated with the latest pictures with the series 2000. Optical Coherence Tomography, and began raving about its wonderful potential and its many uses, comes an enhanced and more precise technology called Spectral Domain OCT. It enhances the wide potential of 2D-OCT and is more precise with less interpolation in the interpretation of results. The TOPCON 3D-OCT-1000 is inbuilt with a nonmydriatic fundus camera and therefore has the unique ability of capturing the color picture and the OCT in one sitting and rather quickly making it comfortable for both patient and doctor. Outline a step-by-step approach to image capturing, analysis and interpretation with a large collection of selected cases. This book will generate the excitement in the reader enough to want to delve into this new 3D domain as much as it did in all of us when we were first exposed to it.

Because of its many advantages optical coherence tomography (OCT) has revolutionized the way in which retinal diseases are screened and managed and how treatments are monitored. In this volume the latest developments and findings are presented by experts in their respective fields. After a short introduction covering the available equipment and the basic techniques, the imaging features of various pathological findings in retinal diseases are presented. The topics cover the outer layers including new modalities for choroid imaging, out-layer diseases such as the various types of macular degeneration, retinal diseases such as diabetic retinopathy and vascular occlusion, and retina and vitreous interface pathologies. The final chapters are dedicated to the practicality of using OCT for the pre- and postsurgical evaluation of the posterior segment and for the differential diagnosis of vitreoretinal diseases as well as in the management of patients with retinal and neuro-ophthalmological diseases. Making the essentials of the recently held ESASO course on OCT available in one volume, this publication is a must-read for experienced as well as trainee ophthalmologists who need to use OCT in their daily practice.
