    2. First interobserver agreement of optical coherence tomography in the bile duct: A multicenter collaborative study

      First interobserver agreement of optical coherence tomography in the bile duct: A multicenter collaborative study
      Background and study aims Optical coherence tomography (OCT) is a new technology available for evaluation of indeterminate biliary strictures. It allows under-the-surface visualization and preliminary studies have confirmed standardized characteristics associated with malignancy. The aim of this study is to evaluate the first interobserver agreement in identifying previously agreed upon OCT criteria and diagnosing of malignant versus benign disease. Patients and methods Fourteen endoscopists were asked to review an atlas ...

    4. Use of OCT Angiography to Diagnose and Manage Atypical Presentations of Macular Telangiectasia Type 2

      Use of OCT Angiography to Diagnose and Manage Atypical Presentations of Macular Telangiectasia Type 2
      Macular telangiectasia Type 2 (MacTel) is a bilateral acquired retinal disease characterized by both vascular changes and atrophy of the retina. The purpose of this case series is to highlight the use of optical coherence tomography angiography (OCTA) as a non-invasive imaging modality to distinguish atypical MacTel from other macular conditions with similar presentations. We performed a retrospective review of patients referred to our academic retinal practice with unconfirmed or ...

    5. Computerized Texture Analysis of Optical Coherence Tomography Angiography of Choriocapillaris in Normal Eyes of Young and Healthy Subjects

      Computerized Texture Analysis of Optical Coherence Tomography Angiography of Choriocapillaris in Normal Eyes of Young and Healthy Subjects
      Computerized texture analysis uses higher-order mathematics to identify patterns beyond what the naked eye can recognize. We tested its feasibility in optical coherence tomography angiography imaging of choriocapillaris. Our objective was to determine sets of parameters that provide coherent and consistent output when applied to a homogeneous, healthy group of patients. This observational cross-sectional study involved 19 eyes of 10 young and healthy Caucasian subjects. En-face macular optical coherence tomography ...

    6. Recommendations for OCTA reporting in retinal vascular disease: A Delphi approach by International Experts

      Recommendations for OCTA reporting in retinal vascular disease: A Delphi approach by International Experts
      Purpose: To develop a consensus nomenclature for reporting optical coherence tomography angiography (OCTA) findings in retinal vascular disease (e.g., diabetic retinopathy, retinal vein occlusion) by international experts. Design: Delphi-based survey SUBJECTS, PARTICIPANTS AND/OR CONTROLS: Twenty-five retinal vascular disease and OCTA imaging experts METHODS, INTERVENTION, OR TESTING: A Delphi method of consensus development was used, comprising two rounds of online questionnaires, followed by a face-to-face meeting conducted virtually. Twenty-five ...

    7. ADVANCED OCT ANALYSIS OF BIOPSY PROVEN VITREORETINAL LYMPHOMA: OCT findings in vitreo-retinal lymphoma

      ADVANCED OCT ANALYSIS OF BIOPSY PROVEN VITREORETINAL LYMPHOMA: OCT findings in vitreo-retinal lymphoma
      Importance: Although the diagnosis of vitreoretinal lymphoma (VRL) can be challenging, early detection is critical for visual prognosis. Objective: To analyze the spectrum of optical coherence tomography (OCT) findings in patients with biopsy-proven VRL and correlate these features with clinical parameters. Design: Retrospective cross-sectional study SETTING: Multicenter chart review from 13 retina, uveitis and ocular oncology clinics worldwide over an 11-year period (2008-2019). Participants: Patients with a diagnosis of biopsy-proven ...

    8. Evaluation of flow of chorioretinal capillaries in healthy black and white subjects using optical coherence tomography angiography

      Evaluation of flow of chorioretinal capillaries in healthy black and white subjects using optical coherence tomography angiography
      This study compared macular capillary parameters between healthy black and white subjects using optical coherence tomography angiography (OCTA). We measured vessel density (VD) of superficial (SCP), intermediate (ICP), and deep (DCP) capillary plexuses and choriocapillaris blood flow area (BFA) of the fovea, parafovea and total 3 mm-diameter circular area centered on the fovea, as well as the foveal avascular zone (FAZ) parameters, controlling for axial length. Black subjects had lower ...

    9. Quantitative Optical Coherence Tomography Angiography (OCTA) Parameters in a Black Diabetic Population and Correlations with Systemic Diseases

      Quantitative Optical Coherence Tomography Angiography (OCTA) Parameters in a Black Diabetic Population and Correlations with Systemic Diseases
      This is a cross-sectional, prospective study of a population of black diabetic participants without diabetic retinopathy aimed to investigate optical coherence tomography angiography (OCTA) characteristics and correlations with systemic diseases in this population. These parameters could serve as novel biomarkers for microvascular complications; especially in black populations which are more vulnerable to diabetic microvascular complications. Linear mixed models were used to obtain OCTA mean values standard deviation and analyze statistical ...

    10. Intraoperative optical coherence tomography of a dislocated intraocular lens

      Intraoperative optical coherence tomography of a dislocated intraocular lens
      An 88-year-old female with pseudoexfoliation syndrome presented with sudden vision loss and was found to have a dislocated one piece intraocular lens (IOL) that was resting on the retina. She underwent 23-gauge pars plana vitrectomy, IOL explantation, and anterior chamber IOL insertion. Intraoperative optical coherence tomography (EnFocus iOCT; Leica, Wetzlar, Germany) was used to assess the position and vault of the IOL on the retinal surface [Figure 1] a. Utilization ...

      MULTIMODAL IMAGING OF ACUTE EXUDATIVE POLYMORPHOUS VITELLIFORM MACULOPATHY WITH OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY AND ADAPTIVE OPTICS SCANNING LASER OPHTHALMOSCOPY
      Purpose: To report a case of acute exudative polymorphous vitelliform maculopathy including the findings of optical coherence tomography angiography and adaptive optics scanning laser ophthalmoscopy. Methods: Findings on clinical examination, color fundus photography, spectral-domain optical coherence tomography, infrared reflectance, autofluorescence, optical coherence tomography angiography, and adaptive optics scanning laser ophthalmoscopy. Results: A 54-year-old white man with no significant medical history and history of smoking presented with bilateral multiple serous and ...

    12. Combined optical coherence tomography and optical coherence elastography for glomerulonephritis classification

      Combined optical coherence tomography and optical coherence elastography for glomerulonephritis classification
      Acute Glomerulonephritis caused by anti-glomerular basement membrane disease has a high mortality due to delayed diagnosis. Thus, an accurate and early diagnosis is critical for preserving renal function. Currently, blood, urine, and tissue-based diagnoses can be time consuming, while ultrasound and CT imaging have relatively low spatial resolution. Optical coherence tomography (OCT) is a noninvasive imaging technique that provides superior spatial resolution (micron scale) as compared to ultrasound and CT ...

  2. About University of Chicago

    University of Chicago

    University of Chicago is a private university located principally in the Hyde Park neighborhood of Chicago. Incorporated in 1890 by the American Baptist Education Society, the school has traditionally dated its founding to July 1, 1891, when William Rainey Harper became President and first member of the faculty; the oil magnate John D. Rockefeller is officially designated "Founder." The University of Chicago held its first classes on October 1, 1892. Chicago was one of the first universities in the country to be conceived as a combination of the American interdisciplinary liberal arts college and the German research university.
