    2. SYNTAX Score, and Pre- and Post-Stent Optical Coherence Tomography Findings in the Left Anterior Descending Coronary Artery in Patients with Stable Angina Pectoris

      SYNTAX Score, and Pre- and Post-Stent Optical Coherence Tomography Findings in the Left Anterior Descending Coronary Artery in Patients with Stable Angina Pectoris
      SYNTAX score (SS) has been reported to be an independent predictor of future cardiac events including target lesion revascularization (TLR). The aim of this study was to assess the relationship between SS and plaque characteristics and post-stent vascular response using optical coherence tomography (OCT) in coronary artery tree and left anterior descending artery (LAD) in patients with stable angina. A total of 179 lesions among 165 patients, including 100 lesions ...

    3. Clinical Significance of Lipid-Rich Plaque Detected by Optical Coherence Tomography : A 4-Year Follow-Up Study

      Clinical Significance of Lipid-Rich Plaque Detected by Optical Coherence Tomography : A 4-Year Follow-Up Study
      Background Lipid-rich plaque (LRP) is thought to be a precursor to cardiac events. However, its clinical significance in coronary arteries has never been systematically investigated. Objectives This study investigated the prevalence and clinical significance of LRP in the nonculprit region of the target vessel in patients undergoing percutaneous coronary intervention (PCI). Methods The study included 1,474 patients from 20 sites across 6 countries undergoing PCI, who had optical coherence ...

    4. Tissue thickness calculation in ocular optical coherence tomography

      Tissue thickness calculation in ocular optical coherence tomography
      Thickness measurements derived from optical coherence tomography (OCT) images of the eye are a fundamental clinical and research metric, since they provide valuable information regarding the eyes anatomical and physiological characteristics, and can assist in the diagnosis and monitoring of numerous ocular conditions. Despite the importance of these measurements, limited attention has been given to the methods used to estimate thickness in OCT images of the eye. Most current studies ...

    7. Automatic segmentation of choroidal thickness in optical coherence tomography

      Automatic segmentation of choroidal thickness in optical coherence tomography
      The assessment of choroidal thickness from optical coherence tomography (OCT) images of the human choroid is an important clinical and research task, since it provides valuable information regarding the eyes normal anatomy and physiology, and changes associated with various eye diseases and the development of refractive error. Due to the time consuming and subjective nature of manual image analysis, there is a need for the development of reliable objective automated ...

    8. Diagnostic bronchoscopy--current and future perspectives

      Diagnostic bronchoscopy--current and future perspectives
      Lung cancer is the leading cause of cancer-related mortality worldwide. Standard bronchoscopy has limited ability to accurately localise and biopsy pulmonary lesions that cannot be directly visualised. The field of advanced diagnostic bronchoscopy is rapidly evolving due to advances in electronics and miniaturisation. Bronchoscopes with smaller outer working diameters, coupled with miniature radial and convex ultrasound probes, allow accurate central and peripheral pulmonary lesion localisation and biopsy while at the ...

    9. Non-invasive assessment of corneal crosslinking changes using polarization sensitive optical coherence tomography

      Non-invasive assessment of corneal crosslinking changes using polarization sensitive optical coherence tomography
      Collagen crosslinking (CXL) has shown promising results in the prevention of the progression of keratoconus and corneal ectasia. However, techniques for in vivo and in situ assessment of the treatment are limited. In this study, ex vivo porcine eyes were treated with a chemical CXL agent (glutaraldehyde), during which polarization sensitive optical coherence tomography (PS-OCT) recordings were acquired simultaneously to assess the sensitivity of the technique to assess changes in ...

    10. Using Optical Coherence Tomography to Assess Corneoscleral Morphology After Soft Contact Lens Wear

      Using Optical Coherence Tomography to Assess Corneoscleral Morphology After Soft Contact Lens Wear
      Purpose. To evaluate the use of optical coherence tomography (OCT) for assessing the effect of different soft contact lenses on corneoscleral morphology. Methods. Ten subjects had anterior segment OCT B-scans taken in the morning and again after 6 h of soft contact lens wear. For each subject, three different contact lenses were used in the right eye on non-consecutive days, including a hydrogel sphere, a silicone hydrogel sphere, and a ...

      Global flash multifocal electroretinogram: early detection of local functional changes and its correlations with optical coherence tomography and visual field tests in diabetic eyes
      Purpose To investigate the correlations of the global flash multifocal electroretinogram (MOFO mfERG) with common clinical visual assessmentsHumphrey perimetry and Stratus circumpapillary retinal nerve fiber layer (RNFL) thickness measurement in type II diabetic patients. Methods Forty-two diabetic patients participated in the study: Ten were free from diabetic retinopathy (DR), while the remainder suffered from mild to moderate nonproliferative diabetic retinopathy. Fourteen age-matched controls were recruited for comparison. MOFO mfERG measurements ...

    12. Biological measurement beyond the quantum limit

      Biological measurement beyond the quantum limit
      Quantum noise places a fundamental limit on the per photon sensitivity attainable in optical measurements. This limit is of particular importance in biological measurements, where the optical power must be constrained to avoid damage to the specimen. By using non-classically correlated light, we demonstrated that the quantum limit can be surpassed in biological measurements. Quantum enhanced microrheology was performed within yeast cells by tracking naturally occurring lipid granules with sensitivity ...

    13. Diurnal Variation of Retinal Thickness with Spectral Domain OCT

      Diurnal Variation of Retinal Thickness with Spectral Domain OCT
      Purpose. To investigate whether diurnal variation occurs in retinal thickness measures derived from spectral domain optical coherence tomography (SD-OCT). Methods. Twelve healthy adult subjects had retinal thickness measured with SD-OCT every 2 h over a 10 h period. At each measurement session, three average B-scan images were derived from a series of multiple B-scans (each from a 5 mm horizontal raster scan along the fovea, containing 1500 A-scans/B-scan) and ...
