    2. Optical Coherence Tomography of Plaque Erosion and Thrombus in Severe Vertebral Artery Stenosis

      Optical Coherence Tomography of Plaque Erosion and Thrombus in Severe Vertebral Artery Stenosis
      A 69-year-old male presented with medically refractory vertebrobasilar insufficiency and paroxysmal subjective dizziness for six months. Severe stenosis of a dominant left V2 vertebral artery segment was identified on digital subtraction angiography (DSA) with an irregular intraluminal filling defect immediately above the stenosis. Optical coherence tomography (OCT) demonstrated a normal lumen at the distal end, with red thrombus detected distal to the stenosis. Atherosclerotic plaque containing fibro-lipid was also identified ...

    3. Neovascularization in Human Intracranial Atherosclerotic In-Stent Restenosis

      Neovascularization in Human Intracranial Atherosclerotic In-Stent Restenosis
      Optical coherence tomography (OCT) has seen widespread use in cardiovascular and interventional endovascular imaging. While scattered reports of intracranial usage have been reported for the assessment of atherosclerotic stenosis, nutrifying neovasculature supplying plaque and neointima have not been demonstrated until now. We report the first in-vivo illustration of this phenomenon, which is a high-resolution depiction of a critical pathway for in-stent restenosis.

    6. Correlation between intracranial vertebral artery stenosis diameter measured by digital subtraction angiography and cross-sectional area measured by optical coherence tomography

      Correlation between intracranial vertebral artery stenosis diameter measured by digital subtraction angiography and cross-sectional area measured by optical coherence tomography
      Background: Intracranial vertebral artery (V4 segment) stenosis quantification traditionally uses the narrowest stenosis diameter. However, the stenotic V4 lumen is commonly irregularly shaped. Optical coherence tomography (OCT) allows a more precise calculation of V4 geometry. We compared the narrowest diameter stenosis (DS), measured by digital subtraction angiography (DSA), with the area stenosis (AS), measured by OCT. We hypothesized that DS is the gold standard for measuring the degree of stenosis ...

Materials and methods Patients with unilateral CM were included in this cross-sectional observational clinical study. Applying OCTA systems operating at 840-nm wavelengths, eyes with CM were imaged. The primary main outcome measures were OCTA images, qualitative evaluation of macular and tumour vasculature, quantitative vascular density (VD), perfusion density ...

    8. Traumatic Macular Hole: Clinical Management and Optical Coherence Tomography Features

      Traumatic Macular Hole: Clinical Management and Optical Coherence Tomography Features
      The complex and uncertain prognosis of traumatic macular hole (TMH) makes it a difficult and challenging problem in clinical management. The features of spontaneously closed TMH and the time of vitrectomy remain unclear. This retrospective study aimed to demonstrate the optical coherence tomography (OCT) features of TMH, explore the relationship between OCT parameters and visual outcomes, and further evaluate the therapeutic effect of surgical management. Seventeen TMH patients were included ...

    9. Superficial Calcification With Rotund Shape Is Associated With Carotid Plaque Rupture: An Optical Coherence Tomography Study

      Superficial Calcification With Rotund Shape Is Associated With Carotid Plaque Rupture: An Optical Coherence Tomography Study
      Background: Plaque rupture is an important etiology for symptomatic carotid stenosis. The role of calcification in the plaque vulnerability has been controversial. We aimed to detect the geometric features of calcifications in carotid plaque and to examine its association with plaque rupture. Methods: Optical coherence tomography assessment of carotid plaque was performed in 88 patients. Calcification shape was evaluated through quantitative measurements of the long and short axis, area size ...

    10. Relationship between monocyte/lymphocyte ratio and non-culprit plaque vulnerability in patients with acute coronary syndrome: An optical coherence tomography study

      Relationship between monocyte/lymphocyte ratio and non-culprit plaque vulnerability in patients with acute coronary syndrome: An optical coherence tomography study
      The importance of monocyte/lymphocyte ratio (MLR) has been indicated in the initiation and progression of coronary artery disease. However, few previous researches demonstrated the relationship between MLR and plaque vulnerability . We aimed to investigate coronary non-culprit plaque vulnerability in patients with acute coronary syndrome (ACS) by optical coherence tomography (OCT). A total of 72 ACS patients who underwent coronary angiography and OCT test in Beijing Anzhen Hospital were included ...

    11. Optical coherence tomography-based deep learning algorithm for quantification of the location of the intraocular lens

      Optical coherence tomography-based deep learning algorithm for quantification of the location of the intraocular lens
      Background: Cataract surgery has been recently developed from sight rehabilitating surgery to accurate refractive surgery. The precise concentration of intraocular lens (IOL) is crucial for postoperative high visual quanlity. The three-dimentional (3D) images of ocular anterior segment captured by optial coherence tomography (OCT) make it possible to evaluate the IOL position in 3D space, which provide insights into factors relavant to the visual quanlity and better design of new functional ...

      Diagnosis of chronic stage of hypertensive retinopathy based on spectral domain optical coherence tomography
      Hypertensive retinopathy refers to the retinal vascular changes associated with systemic arterial hypertension. Hypertensive retinopathy can be divided into chronic and acute phases. A cross‐sectional study was performed to explore a method of measurement in the diameters of retinal vessels for diagnosis of chronic hypertensive retinopathy based on spectral domain optical coherence tomography (SD‐OCT). The central retinal artery diameter (CRAD), the central retinal vein diameter (CRVD), and the ...

    13. Visualization of the Human Intracranial Vasa Vasorum In Vivo Using Optical Coherence Tomography

      Visualization of the Human Intracranial Vasa Vasorum In Vivo Using Optical Coherence Tomography
      The vasa vasorum are a specialized microvasculature that mainly arise from the adventitia and traverse the intimomedial layer of large arteries and veins. These are felt to serve as crucial routes of the delivery for trophic and nutritive factors, as well as regulatory signals. 1 Importantly, they also play a role in pathology via proliferation in atherosclerotic and hypertrophic intimomedia, as well as plaque hemorrhage and dissection via rupture. 2 ...
