OCT is a non-invasive imaging technique that acquires high-resolution images of the ocular structures. It enables clinicians to detect glaucoma in the early stages and efficiently monitor the disease. Optical Coherence Tomography in Glaucoma features updated information on technical applications of OCT in glaucoma, reviews recently published literature and provides clinical cases based on Cirrus and Spectralis OCT platforms. In addition, newer techniques like event and trend analyses for progression, macular ganglion cell analysis, and OCT angiography are discussed. This book will serve as a reference for ophthalmologists and optometrists worldwide with a special interest in OCT imaging providing essential guidance on the application of OCT in glaucoma.




Anterior Segment Optical Coherence Tomography


Book Description

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(TM). 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.




Optical Coherence Tomography in Current Glaucoma Practice


Book Description

Glaucoma is a condition of the eye in which the optic nerve is damaged due to increased fluid pressure in the eye. Left untreated, the condition may lead to permanent blindness. Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-section pictures of the retina, the light-sensitive tissue lining the back of the eye (geteyesmart.org). OCT is commonly used in the evaluation of patients with glaucoma. This manual is a concise guide to the use of OCT for the diagnosis of glaucoma. Beginning with an introduction to OCT, the book then provides in depth discussion on its use in glaucoma. Each of the following chapters describes the use of OCT for analysing associated parts of the eye, including the optic nerve, retinal nerve and ganglion cell, as well as macular and anterior segment OCT. The advantages and common pitfalls in OCT imaging and its interpretation are discussed at length. Key points Concise guide to OCT for diagnosis and evaluation of glaucoma Explains use of OCT for analysis of associated parts of the eye In depth discussion of advantages and common pitfalls in OCT imaging Includes more than 115 images and illustrations




Medical Imaging Systems


Book Description

This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.




Atlas of Ocular Optical Coherence Tomography


Book Description

This book provides a collection of optical coherence tomographic (OCT) images of various diseases of posterior and anterior segments. It covers the details and issues of diagnostic tests based on OCT findings which are crucial for ophthalmologists to understand in their clinical practice. Throughout the chapters all aspects of this non-invasive, popular imaging technique, known for ingenuity and accuracy, is clearly illustrated. Atlas of Ocular Optical Coherence Tomography has been categorized into eleven sections, discussing and illustrating distinct OCT features, as well as showing other image modalities such as fluorescein angiography, fundus autofluorescence, perimetry and laboratory examination. This book also covers choroidal pathologies and vitreous abnormalities. The last section has been allocated to anterior segment disease, including cornea, angle, iris and conjunctival abnormalities. Above all, the numerous images, and detailed descriptions of diseases, make this book an essential guide for general ophthalmologists and ophthalmology residences.

Clinical Applications of Optical Coherence Tomography Angiography


Book Description

"The recent introduction of optical coherence tomography angiography (OCTA) has remarkably expanded our knowledge of different retinal, chorioretinal, and optic disc disorders. OCTA is nowadays often introduced as a routine exam in clinical practice, granting the opportunity to non-invasively investigate retinal and choroidal circulation. In this book, many major experts in posterior eye imaging share their experiences and their latest images and ideas about OCTA"--




Optical Coherence Tomography


Book Description

Optical coherence tomography (OCT) is the optical analog of ultrasound imaging and is emerging as a powerful imaging technique that enables non-invasive, in vivo, high resolution, cross-sectional imaging in biological tissue. This book introduces OCT technology and applications not only from an optical and technological viewpoint, but also from biomedical and clinical perspectives. The chapters are written by leading research groups, in a style comprehensible to a broad audience.




Integrated Intraoperative Ocular Coherence Tomography for Pediatric Ocular Surgery


Book Description

Integrated or microscope-integrated intraoperative ocular coherence tomography (i2OCT or mi-OCT, respectively) has revolutionized real-time augmentation of the surgical operating field. While corneal and retinal specialists have immediately found uses for this technology, others are beginning to use it to improve outcomes and flatten the learning curve. This book presents the use of i2OCT in pediatric ocular surgery. Case scenarios in pediatric retinal disease, corneal lamellar keratoplasty, and even pediatric cataract surgery are discussed. More novel applications highlighted include its use to identify the levator muscle in oculoplastic surgery, especially re-operations, and to assess the results of glaucoma drainage devices. Identifying extraocular muscles in re-operation for strabismus ensures minimal tissue disruption during surgery. Complex pediatric cataract surgeries can be performed far more simply and effectively using integrated ocular coherence tomography technology. This volume provides invaluable information to both early career and experienced pediatric ocular specialists, as well as any researchers who are likely to encounter i2OCT or mi-OCT technology in the future.
