    4. Introduction to swept source optical coherence tomography angiography

      Introduction to swept source optical coherence tomography angiography
      Swept source optical coherence tomography (OCT) technology and OCT-angiography (OCT-A) are two recent developments that have the potential to significantly change our understanding of retinal pathology and retinal vascular pathophysiology. In order to correctly use these technologies to their full diagnostic potential, a thorough understanding of the technology as well as its benefits and limitations is essential. The aim of this review article is to provide an introductory understanding of ...

    5. Intraoperative optical coherence tomography assisted analysis of pars Plana vitrectomy for retinal detachment in morning glory syndrome: a case report

      Intraoperative optical coherence tomography assisted analysis of pars Plana vitrectomy for retinal detachment in morning glory syndrome: a case report
      Background The pathogenesis of non-rhegmatogenous retinal detachment (non-RRD) associated with morning glory syndrome (MGS) is not established, as well as best surgical approach to treat RD. Our purpose was to analyse intraoperative optical coherence tomography data (iOCT) in all steps of pars plana vitrectomy (PPV) for non-RRD in MGS, in order to follow pathophysiological aspects of the disease and to understand the tissues behaviour during surgical workflow. Case presentation Intraoperative ...

    6. Clinical Experience With the First Commercially Available Intraoperative Optical Coherence Tomography System

      Clinical Experience With the First Commercially Available Intraoperative Optical Coherence Tomography System
      BACKGROUND AND OBJECTIVE: A retrospective, single-center case-series was initiated to evaluate initial clinical experience with the first commercially available intraoperative optical coherence tomography system (iOCT). PATIENTS AND METHODS: The Rescan 700 iOCT (Zeiss, Oberkochen, Germany), a spectral-domain OCT system integrated into a surgical microscope, was used in 40 consecutive cases. A standardized review was used to assess whether iOCT imaging resulted in additional information and/or altered decision-making. RESULTS: The ...

      Choroidal Thinning in Diabetes Type 1 Detected by 3-Dimensional 1060 nm Optical Coherence Tomography
      Purpose. To map choroidal (ChT) and retinal thickness (RT) in patients with diabetes type 1 with and without maculopathy and retinopathy in order to compare them with healthy subjects using high speed 3-dimensional (3D) 1060 nm optical coherence tomography (OCT). Methods. Thirty-three eyes from 33 diabetes type 1 subjects (23–57 years, 15 male) divided into groups of without pathology (NDR) and with pathology (DR; including microaneurysms, exudates, clinically significant ...

      3D OCT Video Rendering of Vitreo-macular traction
      This Video shows a real-time rendering of an optical coherence tomography (OCT) data set of a patient with vitreo-macular traction . The data was aquired on a CZM Cirrus HD-OCT 4000 and rendered with a custom plug-in written for MAXON CINEMA 4D. The rendering was done I realtime on a GPU (OpenGL) rendered at 1280 x720p. Although the data was acquired on a Cirrus, this rendering program is platform independent and ...

      A noninvasive, multimodal photoacoustic and optical coherence tomography (PAT/OCT) scanner for three-dimensional in vivo (3D) skin imaging is described. The system employs an integrated, all optical detection scheme for both modalities in backward mode utilizing a shared 2D optical scanner with a field-of-view of ~13 × 13 mm2. The photoacoustic waves were detected using a Fabry Perot polymer film ultrasound sensor placed on the surface of the skin. The sensor ...

  2. About Ludwig Boltzmann Institute

    Ludwig Boltzmann Institute

    Ludwig Boltzmann Institute.  Established in 1961, the Ludwig Boltzmann Society (LBG) is a private organization for research in Austria. Their institutions are involved in medical and humanities, social and cultural and scientific issues. It is named after the great Austrian physicist, mathematician and philosopher, Ludwig Boltzmann, whose broad scientific interest to the way today for the interdisciplinarity of the Ludwig Boltzmann Society. The public and private funded LBG is divided into clusters and institutions, and today employs over 250 people. Since a comprehensive organizational reform of 2002, Ludwig Boltzmann Institute (LBI) as a result of an international tender and assessment procedures. A special feature of the Ludwig Boltzmann Institute is the co-operation with institutional partners.   Rudolf Foundation Clinic is part of the Ludwig Boltzmann Institure.
