PURPOSE To describe image artifacts of optical coherence tomography (OCT) angiography and their underlying causative mechanisms. To establish a common vocabulary for the artifacts observed. METHODS The methods by which OCT angiography images are acquired, generated, and displayed are reviewed as are the mechanisms by which each or all of these methods can produce extraneous image information....

AIMS ILUMIEN I is the largest prospective, non-randomized, observational study of percutaneous coronary intervention (PCI) procedural practice in patients undergoing intra-procedural pre- and post-PCI fractional flow reserve (FFR) and optical coherence tomography (OCT). We report on the impact of OCT on physician decision-making and the association with post-PCI FFR values and early clinical ev...

BACKGROUND The aim of our study was to analyze spectral optical coherence tomography (SD-OCT) findings in a patient with clinical signs of sialidosis. CASE REPORT Fluorescein angiography and spectral optical coherence tomography was performed in a 37-year-old woman using a SD-OCT device with axial resolution of 6 µm. Enzyme assay followed. The patient was diagnosed with type I sialidosis by e...

This review was written for the special issue of IOVS to describe the history of optical coherence tomography (OCT) and its evolution from a nonscientific, historic perspective. Optical coherence tomography has become a standard of care in ophthalmology, providing real-time information on structure and function - diagnosing disease, evaluating progression, and assessing response to therapy, as ...

OBJECTIVES The aim of this study was to evaluate the feasibility and the ability of intravascular optical coherence tomography (OCT) to visualize the components of coronary plaques in living patients. BACKGROUND Disruption of a vulnerable coronary plaque with subsequent thrombosis is currently recognized as the primary mechanism for acute myocardial infarction. Although such plaques are consi...

purpose: comparing the optical coherence tomography (oct) pachymetry patterns in keratoconus suspect and normal people methods: thirty-two keratoconus suspects and 36 healthy eyes were selected within the age range of 20-30 yrs. their pachymetry pattern was obtained through oct visante in the minimum thickness spot, upper and lower corneal difference (i-s), lower temporal, and upper nasal thick...

purpose : to determine the optical coherence tomography (oct) findings in eyes with idiopathic perifoveal retinal telangiectasis (ipt) methods : this study is a retrospective review of patient charts, oct, fundus photography, related to 16 eyes (11 patients). results : the most consistent finding of idiopathic perifoveal telangiectasia seen in 93.7% of eyes (15 eyes) on oct was the presence of ...

Spectral domain optical coherence tomography (SD-OCT) is a noninvasive technique to visualize cross-sectional images of vitreoretinal structures. Image averaging during eye tracking increases the signalto-noise ratio and improves image quality. The point of maximum sensitivity on SD-OCT (known as the “zero-delay line”) is in the vitreous; with increasing depth, the signal is reduced and details...
