    2. Sequential measurement of the neurosensory retina in hypertensive disorders of pregnancy: a model of microvascular injury in hypertensive emergency

      Sequential measurement of the neurosensory retina in hypertensive disorders of pregnancy: a model of microvascular injury in hypertensive emergency
      Optical coherence tomography of the eye suggests the retina thins in normal pregnancy. Our objectives were to confirm and extend these observations to women with hypertensive disorders of pregnancy (HDP). Maternal demographics, clinical/laboratory findings and measurements of macular thickness were repeatedly collected at gestational ages 20 weeks, 20-weeks to delivery, at delivery and postpartum. The primary outcome was the change in macular thickness from non-pregnant dimensions in women with ...

    3. The APOSTEL 2.0 Recommendations for Reporting Quantitative Optical Coherence Tomography Studies

      The APOSTEL 2.0 Recommendations for Reporting Quantitative Optical Coherence Tomography Studies
      Objective: To update the consensus recommendations for reporting of quantitative optical coherence tomography (OCT) study results, thus revising the previously published Advised Protocol for OCT Study Terminology and Elements (APOSTEL) recommendations. Methods: To identify studies reporting quantitative OCT results, we performed a PubMed search for the terms "quantitative" and "optical coherence tomography" from 2015 to 2017. Corresponding authors of the identified publications were invited to provide feedback on the initial ...

    4. The role of optical coherence tomography in the diagnosis of afferent visual pathway problems: A neuroophthalmic perspective (Book Chapter)

      The role of optical coherence tomography in the diagnosis of afferent visual pathway problems: A neuroophthalmic perspective (Book Chapter)
      Optical coherence tomography (OCT) is a noninvasive ocular imaging technique that has become a standard tool in neuroophthalmic practice. Specifically, OCT captures retinal manifestations of neuroaxonal injury caused by lesions along anterior and posterior regions of the afferent visual pathway, in patients presenting with vision loss. More recently, the advent of OCT angiography (OCTA) has enabled evaluation of the choroidal and retinal microvasculature, thus informing our understanding regarding vascular mechanisms ...

    5. Contrast-free optical coherence tomography: Systematic evaluation of non-contrast media for intravascular assessment

      Contrast-free optical coherence tomography: Systematic evaluation of non-contrast media for intravascular assessment
      Background Coronary revascularization using imaging guidance is rapidly becoming the standard of care. Intravascular optical coherence tomography uses near-infrared light to obtain high resolution intravascular images. Standard optical coherence tomography imaging technique employs iodinated contrast dye to achieve the required blood clearance during acquisition. We sought to systematically evaluate the technical performance of saline as an alternative to iodinated contrast for intravascular optical coherence tomography assessment. Methods and results We ...

    6. Functional-Optical Coherence Tomography: A non-invasive approach to assess the sympathetic nervous system and intrinsic vascular regulation

      Functional-Optical Coherence Tomography: A non-invasive approach to assess the sympathetic nervous system and intrinsic vascular regulation
      Sympathetic nervous system dysregulation and vascular impairment in neuronal tissue beds are hallmarks of prominent cardiorespiratory diseases. However, an accurate and convenient method of assessing SNA and local vascular regulation is lacking, hindering routine clinical and research assessments. To address this, we investigated whether spectral domain optical coherence tomography (OCT), that allows investigation of retina and choroid vascular responsiveness, reflects sympathetic activity in order to develop a quick, easy and ...

    7. Measurement of Normative Foveal Avascular Zone Parameters in Healthy Adults Using Optical Coherence Tomography Angiography

      Measurement of Normative Foveal Avascular Zone Parameters in Healthy Adults Using Optical Coherence Tomography Angiography
      Background and Objective: The purpose of this study was to quantify the geometric dimension of the foveal avascular zone (FAZ) area and its index measurement of morphology as a circle (acircularity index) in healthy participants according to age and sex, using optical coherence tomography angiography (OCTA). Study Design/Materials and Method: This is a cross-sectional descriptive study conducted at LV Prasad Eye Institute, India. Written informed consent was obtained from ...

    8. The Optic Disc Drusen Studies Consortium Recommendations for Diagnosis of Optic Disc Drusen Using Optical Coherence Tomography

      The Optic Disc Drusen Studies Consortium Recommendations for Diagnosis of Optic Disc Drusen Using Optical Coherence Tomography
      Background: Making an accurate diagnosis of optic disc drusen (ODD) is important as part of the work-up for possible life-threatening optic disc edema. It also is important to follow the slowly progressive visual field defects many patients with ODD experience. The introduction of enhanced depth imaging optical coherence tomography (EDI-OCT) has improved the visualization of more deeply buried ODD. There is, however, no consensus regarding the diagnosis of ODD using ...

    9. Retinal thickness measured with optical coherence tomography and risk of disability worsening in multiple sclerosis: a cohort study

      Retinal thickness measured with optical coherence tomography and risk of disability worsening in multiple sclerosis: a cohort study
      Background Most patients with multiple sclerosis without previous optic neuritis have thinner retinal layers than healthy controls. We assessed the role of peripapillary retinal nerve fibre layer (pRNFL) thickness and macular volume in eyes with no history of optic neuritis as a biomarker of disability worsening in a cohort of patients with multiple sclerosis who had at least one eye without optic neuritis available. Methods In this multicentre, cohort study ...

    10. The investigation of acute optic neuritis: a review and proposed protocol

      The investigation of acute optic neuritis: a review and proposed protocol
      Optic neuritis is an inflammatory optic neuropathy that affects many patients with multiple sclerosis (MS) at some point during their disease course. Differentiation of acute episodes of MS-associated optic neuritis from other autoimmune and inflammatory optic neuropathies is vital for treatment choice and further patient management, but is not always straightforward. Over the past decade, a number of new imaging, laboratory and electrophysiological techniques have entered the clinical arena. To ...

    11. Spectral-Domain Optical Coherence Tomography of Retinal Nerve Fiber Layer Thickness in NMO Patients

      Spectral-Domain Optical Coherence Tomography of Retinal Nerve Fiber Layer Thickness in NMO Patients
      Background: Neuromyelitis optica (NMO) is a demyelinating syndrome of the central nervous system. NMO might be underdiagnosed at early stages when patients have not yet developed the full spectrum of disease. The aim of this study was to analyze the retinal nerve fiber layer (RNFL) with optical coherence tomography (OCT) and to compare RNFL measurements between NMO patients, patients with relapsing-remitting multiple sclerosis (RRMS), and healthy controls to determine whether ...

The University of Calgary, or "U of C" is currently composed of 16 faculties including a teachers college, law school, and medical school. In 2008 the University of Calgary will be opening a veterinary school bringing the total number of faculties to 17. The campus is located in the north-west quadrant of Calgary.

    The University of Calgary is one of the top research-intensive universities in Canada as it holds the seventh most Canada Research Chairs. It is a member of the G13 (Group of Thirteen), Association of Commonwealth Universities, International Association of Universities, and the Association of Universities and Colleges of Canada. The University of Calgary has a sponsored research revenue of $282 million, with total revenues exceeding $800 million. Being located in Calgary, with Canada's highest concentration of Engineers and Geoscientists, both the Faculty of Science, Department of Geosciences and the Faculty of Engineering maintain close ties to the Petroleum and Geoscience industry.
