      Automated quantification of posterior vitreous inflammation: optical coherence tomography scan number requirements
      Quantifying intraocular inflammation is crucial in managing uveitis patients. We assessed the minimum B-scan density for reliable automated vitreous intensity (VI) assessment, using a novel approach based on optical coherence tomography (OCT). OCT volume scans centered on the macula were retrospectively collected in patients with uveitis. Nine B-scans per volume scan at fixed locations were automatically analyzed. The following B-scan selections were compared against the average score of 9 B-scans ...

      Air pollution is linked to an increased risk of irreversible sight loss, study finds
      Increases in air pollution are linked to an increased risk of irreversible sight loss, according to a new study. Researchers from University College London (UCL) found that even low exposure to air pollution across England, Scotland and Wales appears to impact the risk of age-related macular degeneration (AMD). AMD is the leading cause of irreversible blindness among people over 50 in high-income countries. AMD is linked to the loss of ...

      Association of ambient air pollution with age-related macular degeneration and retinal thickness in UK Biobank
      Aim To examine the associations of air pollution with both self-reported age-related macular degeneration (AMD), and in vivo measures of retinal sublayer thicknesses. Methods We included 115954 UK Biobank participants aged 4069 years old in this cross-sectional study. Ambient air pollution measures included particulate matter, nitrogen dioxide (NO 2 ) and nitrogen oxides (NO x ). Participants with self-reported ocular conditions, high refractive error ( 6 or +6 diopters) and poor spectral-domain optical ...

      IDENTIFICATION OF CARIOUS LESIONS IN ENAMEL USING OPTICAL COHERENCE TOMOGRAPHY
      The aim of this research was to asses wether OCT could be used for early detection of carious/ demineralised lesions in enamel. If application of Optical coherence tomography (OCT) could be used in early, chair-side detection of caries and therefore initiate the prompt treatment strategies required. 10 extracted teeth were selected with no visible carious lesion. All teeth were scanned using Xray Microtomography (XMT). Four teeth were found with areas ...

      Optical Coherence Tomography Substudy of A Prospective Multicenter Randomized Post-Market Trial to Assess the Safety and Effectiveness of the Firehawk™ Rapamycin Target Eluting Cobalt Chromium Coronary Stent System for the Treatment of Atherosclerotic Les
      Aims: Durable polymer drug-eluting stents (DP DES) may contribute to persistent inflammation, delayed endothelial healing and subsequent late DES thrombosis. The aim of this Optical Coherence Tomography (OCT) sub-study was to compare healing and neointimal coverage of a novel bioabsorbable polymer sirolimus-eluting stent (FIREHAWK) (BP DES) versus the DP DES (XIENCE) at 90 days in an all comers patient population. Methods and results: The TARGET All Comers study is a ...

      Heart-rate sensitive optical coherence angiography for measuring vascular changes due to posttraumatic brain injury in mice
      Traumatic brain injury (TBI) results in direct vascular disruption, triggering edema, and reduction in cerebral blood flow. Therefore, understanding the pathophysiology of brain microcirculation following TBI is important for the development of effective therapies. Optical coherence angiography (OCA) is a promising tool for evaluating TBI in rodent models. We develop an approach to OCA that uses the heart-rate frequency to discriminate between static tissue and vasculature. This method operates on ...

      Dynamic measurement of the optical properties of bovine enamel demineralization models using four-dimensional optical coherence tomography
      Dental enamel mineral loss is multifactorial and is consequently explored using a variety of in vitro models. Important factors include the presence of acidic pH and its specific ionic composition, which can both influence lesion characteristics. Optical coherence tomography (OCT) has been demonstrated as a promising tool for studying dental enamel demineralization. However, OCT-based characterization and comparison of demineralization model dynamics are challenging without a consistent experimental environment. Therefore, an ...

      Objectives: The aim of this study was to investigate the spatial location of vulnerable plaques at coronary artery bifurcations using frequency domain-optical coherence tomography. Background: In-vivo data on geometric location of vulnerable plaques in relation to coronary bifurcation are limited. Materials and methods: A total of 40 patients with left anterior descending artery bifurcation were studied. Plaque characteristics in five regions in relation to a side branch were compared: opposite ...

      Multi-system comparison of optical coherence tomography performance with point spread function phantoms
      Point spread function (PSF) phantoms based on unstructured distributions of sub-resolution particles in a transparent matrix have proven effective for evaluating resolution and its spatial variation in optical coherence tomography (OCT) systems. Measurements based on PSF phantoms have the potential to become a standard test method for consistent, objective and quantitative inter-comparison of OCT system performance. Towards this end, we have evaluated three PSF phantoms and investigated their ability to ...

      Visualization of magnetic microcapsules in liquid by optical coherent tomography and control of their arrangement via external magnetic field
      Optical coherence tomography (OCT) is a new, non-invasive, noncontact in vivo imaging technology. We demonstrated that the OCT can be used as a sufficient technique for nanocomposite microcapsule visualization in a liquid medium. As a model system we choose a water/glycerol mixture with viscosity in a variable range from 1.01 to 1.41103 mPa s, including viscosity of a blood plasma. We have found that tomography spatial resolution ...
