    2. Comparison of peripapillary vessel density between preperimetric and perimetric glaucoma evaluated by OCT-angiography

      Comparison of peripapillary vessel density between preperimetric and perimetric glaucoma evaluated by OCT-angiography
      Purpose To determine peripapillary vessel density in eyes with perimetric glaucoma (PG) or preperimetric glaucoma (PPG) compared to normal controls using optical coherence tomography-angiography (OCT-A). Methods We recruited 13 patients with unilateral perimetric normal-tension glaucoma (NTG) and fellow preperimetric NTG showing only inferotemporal retinal nerve fiber layer (RNFL) defect in red-free RNFL photography in both eyes. We also enrolled 9 healthy controls. Using OCT-A, radial peripapillary capillary densities at inferotemporal ...

      Structural Changes of the Macula on Optical Coherence Tomography after Vitrectomy for Proliferative Diabetic Retinopathy
      Purpose: This study aimed to evaluate the relationship between macular structural changes and visual prognosis after pars plana vitrectomy (PPV) for proliferative diabetic retinopathy. Methods: The study included 60 eyes that had undergone PPV. Macular optical coherence tomography (OCT) findings were classified into 5 groups preoperatively and 10 groups postoperatively. Best-corrected visual acuity (BCVA) were analyzed according to pre- and postoperative OCT. Results: From the preoperative OCT, normal fovea with ...

    4. Murine chronic lymph node window for longitudinal intravital lymph node imaging

      Murine chronic lymph node window for longitudinal intravital lymph node imaging
      Chronic imaging windows in mice have been developed to allow intravital microscopy of many different organs and have proven to be of paramount importance in advancing our knowledge of normal and disease processes. A model system that allows long-term intravital imaging of lymph nodes would facilitate the study of cell behavior in lymph nodes during the generation of immune responses in a variety of disease settings and during the formation ...

    5. A Case of Retinal Cavernous Hemangioma Diagnosed with Spectral Domain Optical Coherence Tomography

      A Case of Retinal Cavernous Hemangioma Diagnosed with Spectral Domain Optical Coherence Tomography
      Dear Editor, Retinal cavernous hemangioma (RCH) is a rare, benign, congenital vascular anomaly, incidentally diagnosed in asymptomatic patients. Its characteristics were first reported by Gass [ 1 ] in 1971, as multiple saccular intraretinal aneurysms with dark red color. In most cases, RCH presents with no symptoms, but sometimes it causes visual deterioration when the lesion involves macular and/or vitreous hemorrhage. Several reports have demonstrated that RCH may accompany cutaneous and ...

    6. Intraoperative margin assessment of human breast tissue in optical coherence tomography images using deep neural networks

      Intraoperative margin assessment of human breast tissue in optical coherence tomography images using deep neural networks
      Objective: In this work, we perform margin assessment of human breast tissue from optical coherence tomography (OCT) images using deep neural networks (DNNs). This work simulates an intraoperative setting for breast cancer lumpectomy. Methods: To train the DNNs, we use both the state-of-the-art methods (Weight Decay and DropOut) and a newly introduced regularization method based on function norms. Commonly used methods can fail when only a small database is available ...

    7. Optical Coherence Tomographic Features and Prognosis of Pneumatic Displacement for Submacular Hemorrhage

      Optical Coherence Tomographic Features and Prognosis of Pneumatic Displacement for Submacular Hemorrhage
      Purpose To identify prognostic factors, including optical coherence tomographic features, of visual outcome in exudative age-related macular degeneration with submacular hemorrhage treated with pneumatic displacement. Methods This retrospective interventional case series included 37 eyes with exudative age-related macular degeneration and submacular hemorrhage, all of which underwent pneumatic displacement. The best-corrected visual acuity (BCVA) was measured at diagnosis and at 3 and 6 months after treatment. In addition to demographic and ...

    8. Optical coherence tomography measurements in compressive optic neuropathy associated with dysthyroid orbitopathy

      Optical coherence tomography measurements in compressive optic neuropathy associated with dysthyroid orbitopathy
      Background The purpose of the study was to assess the influence of optic nerve compression on the peripapillary retinal nerve fiber layer (RNFL) thickness in eyes with acute and chronic dysthyroid optic neuropathy (DON). Methods Patients with DON and healthy control subjects underwent peripapillary optical coherence tomography (OCT) scanning with the Cirrus HD-OCT. Patients were classified as acute (within 6 months from the onset of DON) versus chronic (6 months ...

    9. Error rate of automated choroidal segmentation using swept-source optical coherence tomography

      Error rate of automated choroidal segmentation using swept-source optical coherence tomography
      Purpose To investigate the error rate of automated choroidal segmentation and the effect of frame averaging on error rate. Methods A horizontal B scan at the fovea was performed in patients having various retinochoroidal disorders using swept-source optical coherence tomography (OCT) with frame-averaging technique. Scanned images were classified into four morphological groups: normal from fellow eyes (N F ), normal from pathologic eyes (N P ), retinal abnormality (R) and retinochoroidal abnormality ...

      Comparison of dual rotating Scheimpflug-Placido, swept-source optical coherence tomography, and Placido-scanning-slit systems
      Purpose To compare measurements of corneal indices using dual rotating ScheimpflugPlacido, swept-source optical coherence tomography (OCT), and Placidoscanning-slit systems. Setting Kangbuk Samsung Hospital, Seoul, South Korea. Design Prospective evaluation of diagnostic tests. Methods Corneal topography measurements were performed using dual rotating ScheimpflugPlacido (Galilei G2), swept-source OCT (Casia SS-1000), and Placidoscanning-slit (Orbscan IIz) systems. The intraclass correlation coefficients (ICCs) and Bland-Altman plots were used to evaluate the agreement between measurements. Results ...

    11. Broadband supercontinuum generation using a hollow optical fiber filled with copper-ion-modified DNA

      Broadband supercontinuum generation using a hollow optical fiber filled with copper-ion-modified DNA
      We experimentally demonstrated supercontinuum generation through a hollow core photonic bandgap fiber (HC-PBGF) filled with DNA nanocrystals modified by copper ions in a solution. Both double-crossover nano DNA structure and copper-ion-modified structure provided a sufficiently high optical nonlinearity within a short length of hollow optical fiber. Adding a higher concentration of copper ion into the DNA nanocrystals, the bandwidth of supercontinuum output was monotonically increased. Finally, we achieved the bandwidth ...

      Purpose To analyze choroidal sublayers and vascular diameter in children, and to compare these choroidal features with those of adults. Design Retrospective observational study Methods This study included 96 eyes from 48 healthy children and 54 eyes from 27 healthy adults. The subfoveal choroidal thickness, large choroidal vessel layer thickness, medium choroidal vessel layer-choriocapillaris layer thickness, and large choroidal vessel diameter were estimated. The ratio of thickness of the large ...
