  Purpose To evaluate the vessel density of macula according to analysis area in health subjects using optical coherence tomography angiography (OCTA). Methods We retrospectively analyzed 30 eyes of 20 healthy people who underwent OCTA. We measured vessel density (VD) according to analysis area and foveal avascular zone (FAZ) size of superficial capillary plexus (SCP) and deep capillary plexus (DCP). The analysis areas were classified as 3 3 mm scan area ...

5. Measurable Range of Subfoveal Choroidal Thickness With Conventional Spectral Domain Optical Coherence Tomography
  
  Explore TVST Journal Oct 6 2018 Ophthalmology
  
  Purpose : We investigate the measurable range of subfoveal choroidal thickness (SFCT) with conventional spectral domain optical coherence tomography (SD-OCT) in normal healthy eyes. Methods : All subjects underwent an SD-OCT horizontal line scan centered at the fovea with standard and enhanced depth imaging (EDI) techniques. Two independent observers manually measured SFCT on standard and EDI-OCT images, if two choroidal borders were identified. The rate of successful measurement with standard OCT was ...

7. Fouling development in direct contact membrane distillation: Non-invasive monitoring and destructive analysis
  
  Explore ScienceDirect Dec 30 2017 NDE/NDT , Other Non-Medical
  
  Fouling development in direct contact membrane distillation (DCMD) for seawater desalination was evaluated combining in-situ monitoring performed using optical coherence tomography (OCT) together with destructive techniques. The non-invasive monitoring with OCT provided a better understanding of the fouling mechanism by giving an appropriate sampling timing for the membrane autopsy. The on-line monitoring system allowed linking the flux trend with the structure of fouling deposited on the membrane surface. The water ...

8. Automatic Subretinal Fluid Segmentation of Retinal SD-OCT Images With Neurosensory Retinal Detachment Guided by Enface Fundus Imaging
  
  Explore IEEE Xplore Dec 22 2017 Ophthalmology
  
  Objective: Accurate segmentation of neurosensory retinal detachment (NRD) associated subretinal fluid in spectral domain optical coherence tomography (SD-OCT) is vital for the assessment of central serous chorioretinopathy (CSC). A novel two-stage segmentation algorithm was proposed, guided by Enface fundus imaging. Methods: In the first stage, Enface fundus image was segmented using thickness map prior to detecting the fluid-associated abnormalities with diffuse boundaries. In the second stage, the locations of the ...

9. Comparison of peripapillary vessel density between preperimetric and perimetric glaucoma evaluated by OCT-angiography
  
  Explore Journals | PLOS Aug 31 2017 Ophthalmology
  
  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 ...

  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 ...

11. Murine chronic lymph node window for longitudinal intravital lymph node imaging
  
  Explore Nature Publishing Group Jul 11 2017
  
  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 ...

12. A Case of Retinal Cavernous Hemangioma Diagnosed with Spectral Domain Optical Coherence Tomography
  
  Explore Digital Object Identifier System May 28 2017 Ophthalmology
  
  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 ...

  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 ...
