    2. 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 ...

    4. 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).

    5. 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 ...

    6. Diagnosis of chronic stage of hypertensive retinopathy based on spectral domain optical coherence tomography

      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 ...

    7. 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 ...

    8. Microvascular retinal changes in pre-clinical diabetic retinopathy as detected by optical coherence tomographic angiography

      Microvascular retinal changes in pre-clinical diabetic retinopathy as detected by optical coherence tomographic angiography
      Purpose To investigate microvascular abnormalities in diabetic patients without conventional clinical signs of diabetic retinopathy (DR). Methods In this cross-sectional observational cohort study, the study group included randomly chosen participants of a community-based cohort with diabetes type 2 without DR, and the control group consisted of non-diabetic individuals from a population-based study. All participants underwent optical coherence tomographic angiography (OCTA). Results Upon OCTA, 118 (40.4%) eyes of the study ...

    9. Serial OCT Imaging of Multiple Woven-Appearing Lesions in a Single Patient Demonstrating Long-Term Clinical Stabilit

      Serial OCT Imaging of Multiple Woven-Appearing Lesions in a Single Patient Demonstrating Long-Term Clinical Stabilit
      We report the case of a 58-year-old man with a history of myocardial infarction presenting with chest pain. Serial coronary artery optical coherence tomography over a 3-year period showed multiple woven-appearing lesions without progression, indicating that this type of lesion is potentially stable. ( Level of Difficulty: Advanced. )

      Results of Optical Coherence Tomography Angiography and Visual Acuity Under Varying Contrast and Luminance Conditions
      Purpose: To assess early retinal microvascular and functional changes in diabetic patients without clinical evidence of diabetic retinopathy with optical coherence tomography angiography and central visual analyzer. Methods: This was an observational casecontrol study of diabetic patients without diabetic retinopathy and nondiabetic controls. Patients underwent optical coherence tomography angiography imaging and visual acuity testing using the central visual analyzer. The foveal avascular zone area and the capillary density in the ...

      Diagnostic accuracy of intracoronary optical coherence tomography-derived fractional flow reserve for assessment of coronary stenosis severity
      ims: A novel method for computation of fractional flow reserve (FFR) from optical coherence tomography (OCT) was developed recently. This study aimed to evaluate the diagnostic accuracy of a new OCT-based FFR (OFR) computational approach, using wire-based FFR as the reference standard. Methods and results: Patients who underwent both OCT and FFR prior to intervention were analysed. The lumen of the interrogated vessel and the ostia of the side branches ...

      Percutaneous coronary intervention for a Chinese familial hypercholesterolemia homozygous under the guidance of optical coherence tomography
      Homozygous familial hypercholesterolemia developed into severe cardiovascular consequences early. Untreated HoFH usually cannot survive over 30 years old. Acute coronary syndrome(ACS) caused by plaque rupture is one of the main causes of death in HoFH. As the highest resolution intravascular imaging technique, optical coherence tomography(OCT) can clearly show the thickness and structural characteristics of atherosclerotic plaque caps. In this study, a Chinese male HoFH received percutaneous coronary intervention ...

      Optical coherence tomography of spontaneous basilar artery dissection in a patient with acute ischemic stroke
      The diagnosis of intracranial arterial dissection (IAD) may be challenging and multimodal imaging techniques are often needed to confirm the diagnosis. Previous studies have based their criteria for diagnosis of IAD on conventional angiography, computed tomography or magnetic resonance imaging. We report a case with acute ischemic stroke due to spontaneous basilar artery dissection in which intravascular optical coherence tomography (OCT) was used to show features of IAD. A 59-year-old ...
