      Live imaging and functional changes of the inner ear in an animal model of Meniere’s disease
      The symptoms of Menieres disease (MD) are generally considered to be related to endolymphatic hydrops (EH). There are many recent reports supporting the possibility that vasopressin (VP) is closely linked to the formation of EH in Menieres disease. Based on this, we developed a clinically relevant animal model of Menieres disease in which a VP type 2 receptor agonist was administered after electrocauterization of the endolymphatic sac. We report live ...

      Comparison of post‐stent optical coherence tomography findings: Layered versus non‐layered culprit lesions
      Objectives This study aimed to investigate the vascular response of lesions with a layered phenotype. Background Recent studies have shown that layered plaques at culprit lesions detected by optical coherence tomography (OCT) have greater plaque burden and more inflammatory features than non‐layered plaques. Methods This is a retrospective observational study. A total of 193 target lesions from 193 patients [100 patients with acute coronary syndromes (ACS) and 93 with ...

      OCT-Based Management of Nilotinib-Associated CAD in a Patient With Chronic Myeloid Leukemia
      Chronic myeloid leukemia (CML) is a myeloproliferative disorder of pluripotent hematopoietic stem cells caused by Bcr-Abl tyrosine kinase, the product of the Philadelphia chromosome. Bcr-Abl tyrosine kinase inhibitors (TKIs) have dramatically improved the prognosis of patients with CML (1). Although w 20% of patients with CML develop intolerance or resistance to the first Bcr-Abl TKI, imatinib mesylate, several second-generation TKIs, including nilotinib, dasatinib, and bosutinib, have overcome this issue (2 ...

      OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY STUDY OF CHOROIDAL NEOVASCULARIZATION ASSOCIATED WITH EARLY-ONSET DRUSEN
      Purpose: To report three middle-aged cases with choroidal neovascularization (CNV) associated with early-onset drusen documented with optical coherence tomography angiography (OCTA). Methods: Three patients with bilateral early-onset drusen were referred to our hospital. Fundus examination, fluorescein angiography, indocyanine green angiography , OCTA, and other multimodal imaging were performed. Results: Case 1 involved a 47-year-old woman who presented with sudden unilateral anorthopia. She had no previous systemic pathologies. Funduscopic examination and fluorescein ...

      Extraction of membrane structure in eyeball from MR volumes
      This paper presents an accurate extraction method of spherical shaped membrane structures in the eyeball from MR volumes. In ophthalmic surgery, operation field is limited to a small region. Patient specific surgical simulation is useful to reduce complications. Understanding of tissue structure in the eyeball of a patient is required to achieve patient specific surgical simulations. Previous extraction methods of tissue structure in the eyeball use optical coherence tomography (OCT ...

      Visualizing dynamics of angiogenic sprouting from a three-dimensional microvasculature model using stage-top optical coherence tomography
      Three-dimensional (3D)in vitromicrovasculature in a polydimethylsiloxane-based microdevice was developed as a physiologically relevant model of angiogenesis. The angiogenic process is monitored using stage-top optical coherence tomography (OCT). OCT allows non-invasive monitoring of the 3D structures of the prepared host microvasculature and sprouted neovasculature without fluorescence staining. OCT monitoring takes only a few minutes to scan through the several-millimetre scale range, which provides the advantage of rapid observation of living ...

      Optimization of a dispersion-tuned wavelength-swept fiber laser for optical coherence tomography
      We optimized parameters of a dispersion-tuned wavelength-swept fiber laser by numerically analyzing dynamic characteristics. The optimized laser is experimentally demonstrated and applied to the swept-source optical coherence tomography (SS-OCT) system. The dispersion-tuned wavelength-swept laser (DT-WSL) is a unique tunable fiber laser, whose lasing wavelength can be tuned rapidly without any mechanical tunable filters. Although the wavelength of a DT-WSL can be swept rapidly and widely, the broadening of the instantaneous ...

      Eye motion corrected OCT imaging with Lissajous scan pattern
      Ophthalmic optical coherence tomography (OCT) is a powerful tool which provides high resolution three dimensional (3D) volumetric image of human retina. However, the measurement data of OCT suffer motion artifact due to the involuntary eye motion during data acquisition. To eliminate this motion artifact and provide the true shape of retinal image, an eye motion corrected OCT imaging method based on Lissajous scan pattern is proposed in this paper. In ...

      Optical coherence tomography and intravascular ultrasound evaluation of cardiac allograft vasculopathy with and without intimal neovascularization
      Aims Neovascularization is closely associated with plaque progression in non-heart transplantation subjects; on the other hand, cardiac allograft vasculopathy causes unfavourable outcomes. Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) can provide microscopic assessment in vivo . The aim of this study was to investigate the impact of neovascularization on intimal proliferation. Methods and results Both IVUS and OCT were attempted in 45 consecutive patients during annual catheterization after heart transplantation ...
