    3. Spatial analysis of thickness changes in ten retinal layers of Alzheimer’s disease patients based on optical coherence tomography

      Spatial analysis of thickness changes in ten retinal layers of Alzheimer’s disease patients based on optical coherence tomography
      The retina is an attractive source of biomarkers since it shares many features with the brain. Thickness differences in 10 retinal layers between 19 patients with mild Alzheimers disease (AD) and a control group of 24 volunteers were investigated. Retinal layers were automatically segmented and their thickness at each scanned point was measured, corrected for tilt and spatially normalized. When the mean thickness of entire layers was compared between patients ...

    4. Clinical use of intracoronary imaging. Part 2: acute coronary syndromes, ambiguous coronary angiography findings, and guiding interventional decision-making: an expert consensus document of the European Association of Percutaneous Cardiovascular Intervent

      Clinical use of intracoronary imaging. Part 2: acute coronary syndromes, ambiguous coronary angiography findings, and guiding interventional decision-making: an expert consensus document of the European Association of Percutaneous Cardiovascular Intervent
      This consensus document is the second of two reports summarizing the views of an expert panel organized by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) on the clinical use of intracoronary imaging including intravascular ultrasound (IVUS), optical coherence tomography (OCT), and near infrared spectroscopy (NIRS)-IVUS. Beyond guidance of stent selection and optimization of deployment, invasive imaging facilitates angiographic interpretation and may guide treatment in acute coronary syndrome. Intravascular ...

The aim of the study was to evaluate tissue modifications in the RMS edges over time, assessed by different invasive imaging modalities. Methods The patients treated with the device were assessed by optical coherence tomography (OCT), grayscale intravascular ultrasound (IVUS), and virtual histology IVUS at baseline and 12 months ...

      Differences in retinal nerve fiber layer thickness measured by spectral domain optical coherence tomography between primary congenital glaucoma patients and healthy children
      Purpose To evaluate the retinal nerve fiber layer (RNFL) thickness using spectral domain optical coherence tomography (SD-OCT) in a population of children diagnosed with primary congenital glaucoma (PCG). Methods Cross-sectional study where 59 eyes from 59 children diagnosed with PCG and 87 eyes from 87 healthy children were evaluated by SD-OCT to measure the RNFL. The global average peripapillary RNFL thickness and sectional RNFL thickness were evaluated in both groups ...

    7. Spontaneous Coronary Artery Dissection: Pathophysiological Insights From Optical Coherence Tomography

      Spontaneous Coronary Artery Dissection: Pathophysiological Insights From Optical Coherence Tomography
      Objectives This study used optical coherence tomography to investigate the mechanism of false lumen (FL) formation in spontaneous coronary artery dissection (SCAD) by studying: 1) differences between fenestrated and nonfenestrated SCAD; 2) vasa vasorum density; and 3) light attenuation characteristics of the FL. Background SCAD is an increasingly recognized cause of acute coronary syndromes , characterized by FL formation and compression of the true lumen (TL). The mechanisms underlying FL formation ...

    8. Utility of optical coherence tomography angiography in detecting vascular retinal damage caused by arterial hypertension

      Utility of optical coherence tomography angiography in detecting vascular retinal damage caused by arterial hypertension
      Objective: To evaluate the potential utility of perfusion density measurements to discriminate patients with arterial hypertension by cardiovascular risk category. Methods: In this cross-sectional study, one eye per subject was evaluated (N=73). The study cohort was divided into three groups according to the clinical criteria established by the European Guidelines for Arterial Hypertension: 26 controls, 24 patients with low cardiovascular risk, and 23 patients with very high cardiovascular risk ...

    9. Qualitative and quantitative neointimal characterization by optical coherence tomography in patients presenting with in-stent restenosis

      Qualitative and quantitative neointimal characterization by optical coherence tomography in patients presenting with in-stent restenosis
      Aims To describe optical coherence tomography (OCT) findings in patients with in-stent restenosis (ISR) and determine predictors of neointimal patterns and neoatherosclerosis. Methods and results Patients undergoing OCT prior to PCI for ISR in three European centres were included. Analyses were performed in a core laboratory. Qualitative and quantitative [gray-scale signal intensity (GSI)] neointima analyses were performed on a per quadrant basis. A total of 107 patients were included. Predominantly ...

      Optical Coherence Tomography Thickness Measurements of the Extraocular Rectus Muscle Tendons in Graves' Ophthalmopathy
      PURPOSE: To examine extraocular rectus muscle tendons in patients with Graves' ophthalmopathy using optical coherence tomography (OCT). METHODS: This was a cross-sectional observational study conducted with 55 healthy controls, 45 patients with clinically inactive Graves' ophthalmopathy, and 12 patients with clinically active Graves' ophthalmopathy. Scanning was performed at the 3- and 9-o'clock positions. The medial rectus tendon thickness was measured at 7.2 and 9.2 mm from the ...

      Intercalary membrane as the inner wall overlying optic and chorio-retinal colobomas. Deep penetration Swept Source-OCT study
      Five eyes of four patients were studied to analyze the structure of the inner wall of optic and chorioretinal colobomas using swept-source optical coherence tomography (SS-OCT). The colobomatous cavities and their relationship with adjacent structures were examined. SS-OCT permitted the study of the colobomatous cavities in all cases. In four of those cases, a Y-shaped intercalary membrane (ICM) was identified, with an origin in the retinal nerve fiber layer (RNFL ...

    13. Optical coherence tomography or intravascular ultrasound to optimize coronary stent implantation

      Optical coherence tomography or intravascular ultrasound to optimize coronary stent implantation
      Optical coherence tomography (OCT) provides high-resolution tomographic images of the coronary arteries. 1 , 2 Spatial resolution of OCT (15m) is 10 times better than that of intravascular ultrasound (IVUS) (150m). 1 , 2 However, OCT needs complete blood clearance from the coronary lumen and, therefore, requires the use of contrast media. 1 , 2 OCT is unable to penetrate and see throughout red thrombus (that casts major dorsal shadowing) whereas IVUS is ...

    14. Optical Coherence Tomography Findings in Patients With Recanalized Coronary Thrombi Treated With Bioresorbable Vascular Scaffolds

      Optical Coherence Tomography Findings in Patients With Recanalized Coronary Thrombi Treated With Bioresorbable Vascular Scaffolds
      Introduction Recanalized coronary thrombi (RCT) are rarely recognized in real-world clinical practice. Incidence and functional significance of RCT remain unclear. High-resolution imaging modalities, such as optical coherence tomography (OCT), may provide novel insight to further characterize this unique phenomenon. 1 , 2 We present a case series of RCT treated with bioresorbable vascular scaffold (BVS). Case 1 A 75-year-old man with a previous history of an inferior myocardial infarction was admitted ...
