    1. Optical Coherence Tomography Angiography of the Eye

      Optical Coherence Tomography Angiography of the Eye

      Optical coherence tomography (OCT) angiography is an important new imaging modality that is already being used by ophthalmologists in retina centers worldwide. It uses motion as intrinsic contrast, thus obviating the need to inject any intravenous dye. It uses infrared light that is invisible to the patient, and only requires few seconds per scan. This makes it both easier to use and much better tolerated by patients than traditional dye-based fluorescein angiography (FA) and indocyanine green (ICG) angiography. Inside Optical Coherence Tomography Angiography of the Eye Drs. David Huang, Bruno Lumbroso, Yali Jia, and Nadia Waheed include detailed information on ...

    4. Optical Coherence Tomography and Wide-Field Fluorescein Angiography in Retinopathy of Prematurity (Book Chapter)

      Optical Coherence Tomography and Wide-Field Fluorescein Angiography in Retinopathy of Prematurity (Book Chapter)

      The advent and adaptation of many imaging modalities promise to revolutionize our understanding of retinopathy of prematurity (ROP) by improving the detection, diagnosis, and monitoring of response to treatment of this disease. Diagnosis and classification of ROP traditionally relies on an eye exam by an ophthalmologist expert in this area who characterizes extent and character of retinal vascularization via indirect ophthalmoscopy. Many tools now exist that allow for data acquisition by nurses, technicians, and other trained staff with the images analyzed in a more centralized location. We will focus on two rapidly evolving technologies, optical coherence tomography (OCT), and wide ...

    5. Optical Coherence Tomography Angiography in Macular Edema (Book Chapter)

      Optical Coherence Tomography Angiography in Macular Edema (Book Chapter)

      OCT angiography is a promising new method to visualize the retinal vasculature and choroidal vascular layers in the macular area and provides depth resolved functional information of the blood flow in the vessels. Given that the main moving elements in the eye fundus are contained in vessels, determining a vascular decorrelation signal enables visualization of 3-dimensional retinal and choroidal vascular network without the administration of intravenous dye and thus reducing the risk of potential adverse events.

    15. Optical Coherence Tomography: Role in Percutaneous Coronary Intervention (Book Chapter)

      Optical Coherence Tomography: Role in Percutaneous Coronary Intervention (Book Chapter)

      Optical coherence tomography (OCT) is an imaging modality that utilizes back-reflection of near-infrared light. Superior resolution intra-coronary imaging, including assessment of plaque morphology and characteristics as well as imaging stents and post-stent complications have made OCT a powerful research tool, and more recently a clinical tool for guidance of PCI. Visualization of coronary lesions with OCT and their characterization as lipid-rich, fibrous, or fibro-calcific plaque can influence percutaneous coronary intervention (PCI) procedural planning. OCT has contributed significantly to the understanding of culprit lesion pathophysiology in acute coronary syndromes (ACS). ACS culprit lesions have been categorized by OCT features as resulting ...

      Optical Coherence Tomography in Grafts (Book Chapter)

      Coronary artery bypass graft (CABG) is a commonly used surgery to treat patients with complex artery disease. Long-term outcome of specifically saphenous vein grafts (SVG) is considered unfavorable, while it is the most commonly used conduit. The SVG is prone to occlude and half of the patients will develop vein graft failure (VGF) within 10 years. VGF is the result of the accelerated atherosclerosis that differs from what is seen in native coronaries. Revascularization of SVGs is considered challenging, due to their challenging anatomy and embolic nature. Optical coherence tomography (OCT) imaging is an invasive imaging technique that can be ...
