    2. Optical coherence tomography angiography for the diagnosis of granulomatosis with polyangiitis with serous retinal detachment

      Explore LWW Online Ophthalmology
      Optical coherence tomography angiography for the diagnosis of granulomatosis with polyangiitis with serous retinal detachment
      Rationale: Granulomatosis with polyangiitis (GPA) is a rare systemic autoimmune disease of unknown etiology. GPA affects multiple ocular tissues, most commonly the orbit, conjunctiva, cornea, and sclera. Retinal and choroidal manifestations are rare in GPA, but they often include choroidal neovascularization (CNV). Patient concerns: A 36-year-old man was diagnosed with GPA. He had been taking oral steroid treatment for 8 years. He experienced disease recurrence and the dose of oral ...

      Explore SPIE Digital Library
      High-spatial-resolution deep tissue imaging with spectral-domain optical coherence microscopy in the 1700-nm spectral band
      We present three-dimensional (3-D) high-resolution spectral-domain optical coherence microscopy (SD-OCM) by using a supercontinuum (SC) fiber laser source with 300-nm spectral bandwidth (full-width at half-maximum) in the 1700-nm spectral band. By using low-coherence interferometry with SC light and a confocal detection scheme, we realized lateral and axial resolutions of 3.4 and 3.8m in tissue ( n =1.38), respectively. This is, to the best of our knowledge, the highest ...

      Changes in choriocapillaris and retinal morphology after laser photocoagulation by OCT angiography
      Rationale: Earlier studies have shown that laser photocoagulation treatments are associated with good long-term visual acuity in most patients with severe nonproliferative diabetic retinopathy (S-NPDR). Histopathologic studies of autopsied eyes have demonstrated defects in the choriocapillaris beneath the retinal laser lesions secondary to photocoagulation for S-NPDR. These lesions have been observed to expand centrifugally over time especially in the posterior pole, and the atrophy of the retinal pigment epithelium (RPE ...

      Purpose: To study B-scan flow overlay and en face flow optical coherence tomography angiography (OCT-A) images of Type 3 neovascularization (NV) and to characterize a staging system for Type 3 NV based on the OCT-A findings. Methods: We retrospectively collected data on consecutive treatment-naive eyes with Type 3 NV. All eyes underwent fluorescein angiography, indocyanine green angiography, structural spectral domain OCT, and OCT-A (AngioPlex). Localization and extension of abnormal flows ...

      Wavelength Dependence of Ultrahigh-Resolution Optical Coherence Tomography Using Supercontinuum for Biomedical Imaging
      Optical coherence tomography (OCT) is a noninvasive cross-sectional imaging technique with micrometer resolution. The theoretical axial resolution is determined by the center wavelength and bandwidth of the light source, and the wider the bandwidth, the higher the axial resolution. The characteristics of OCT imaging depend on the optical wavelength used. In this paper, we investigated the wavelength dependence of ultrahigh-resolution (UHR) OCT using a supercontinuum for biomedical imaging. Wideband, high-power ...

      The combination assessment of lipid pool and thrombus by optical coherence tomography can predict the filter no-reflow in primary PCI for ST elevated myocardial infarction
      The usefulness of distal protection devices is still controversial. Moreover, there is no report on thrombus evaluation by using optical coherence tomography (OCT) for determining whether to use a distal protection device. The aim of the present study was to investigate the predictor of filter no-reflow (FNR) by using OCT in primary percutaneous coronary intervention (PCI) for ST-elevated acute myocardial infarction (STEMI). We performed preinterventional OCT in 25 patients with ...

  4. About Nagoya University

    Nagoya University

    Nagoya University is a Japanese national university headquartered in Chikusa-ku, Nagoya. It is one of the former 9 imperial universities. Nagoya University began its history in 1871 with its temporary hospital standing on a site where the conference chamber for the former Nagoya clan once stood, and the temporary medical school standing on a site where the magistrate's office for the former Nagoya clan once stood. Thereafter, many transitions took place, and the Aichi Medical College was established in 1920. In 1931, the management of the Aichi Medical College was transferred to the national government and the Nagoya Medical College was newly established in the same year. In 1939, the Nagoya Imperial University was established with the addition of the School of Science and Engineering and the School of Medicine, thus absorbing the Nagoya Medical College.
