    2. Impact of Head Tilt on Optical Coherence Tomography Image Orientation

      Impact of Head Tilt on Optical Coherence Tomography Image Orientation
      Purpose: Head tilt can have an impact on the orientation of posterior pole images. We conducted this study to determine the effect of head tilt on image orientation measured by the fovea - Bruchs membrane opening (FoBMO) angle with optical coherence tomography (OCT) imaging. Methods: The study included 56 healthy subjects with mean (range) age of 33 (18-61) years. The dominant eye was first determined. To measure head tilt , a smartphone ...

    3. Simultaneous measurement of refractive index and thickness of multilayer systems using Fourier domain optical coherence tomography, part 2: implementation

      Simultaneous measurement of refractive index and thickness of multilayer systems using Fourier domain optical coherence tomography, part 2: implementation
      We introduce a theoretical method for simultaneous measurement of refractive index and thickness of multilayer systems using Fourier domain optical coherence tomography (FD-OCT) without any auxiliary arrangement. The input data to the formalism are the FD-OCT measured optical path lengths (OPLs) and properly selected spectral components of FD-OCT interference spectrum. The outputs of the formalism can be affected significantly by uncertainty in measuring the OPLs. An optimization method is introduced ...

    4. Simultaneous measurement of refractive index and thickness of multilayer systems using Fourier domain optical coherence tomography, part 1: theory

      Simultaneous measurement of refractive index and thickness of multilayer systems using Fourier domain optical coherence tomography, part 1: theory
      We introduce a theoretical framework for simultaneous refractive index and thickness measurement of multilayer systems using the Fourier domain optical coherence tomography (FD-OCT) system without any previous information about the item under investigation. The input data to the new formalism are the FD-OCT measured optical path lengths and properly selected spectral components of the FD-OCT interference spectrum. No additional arrangement, reference reflector, or mechanical scanning is needed in this approach ...

    5. Multimodal imaging including spectral-domain optical coherence tomography and confocal near-infrared reflectance for characterization of lacquer cracks in highly myopic eyes

      Multimodal imaging including spectral-domain optical coherence tomography and confocal near-infrared reflectance for characterization of lacquer cracks in highly myopic eyes
      Purpose To compare multimodal imaging in detecting lacquer cracks in highly myopic eyes, and to correlate these findings with those of spectral-domain optical coherence tomography (SD-OCT). Methods An observational case series study. Patients with a refractive error worse than 8 diopters and lacquer cracks were recruited. The rates of detection of the lacquer cracks using multimodal imaging including near-infrared reflectance (NIR) imaging, fundus autofluorescence (FAF) imaging, and fluorescence angiography (FA ...

    6. Using retinal architecture to help characterize multiple sclerosis patients

      Using retinal architecture to help characterize multiple sclerosis patients
      Objective: We compared retinal nerve fibre layer (RNFL) thickness and visual function in a heterogeneous multiple sclerosis (MS) cohort to determine whether optical coherence tomography (OCT) may complement the existing methods used to characterize MS patients. Design: Cross-sectional cohort study. Participants: One hundred and ninety-three patients with optic neuritis (ON) as a clinically isolated syndrome (CIS) (n = 63), relapsing-remitting MS (RRMS) (n = 108), secondary progressive MS (SPMS) (n = 13), and ...

  2. About University of Ottawa

    University of Ottawa

    The University of Ottawa is a bilingual, research-intensive, non-denominational, international university in Ottawa, Ontario. It is one of the oldest universities in Canada, and was originally established as the College of Bytown in 1848 by the Missionary Oblates of Mary Immaculate. Formerly a liberal arts college, it has been teaching pure and applied sciences in both French and English since the 1800s. The university has been conferring Bachelor's degrees since 1872, Master's degrees since 1875, and Doctorates since 1888. Saint Paul University is federated with the university and is also located in Ottawa.

    The University of Ottawa is ranked 5th in research-intensity, and 9th in total-research funding in Canada It is a member of the Group of Thirteen, a league of the most research-intensive universities in the country. It was ranked 10th in Canada in the tenth edition (1998) of the Gourman Report university ranking guide. In the THES - QS World University Rankings of the top 500 universities in the world for 2007, the University of Ottawa placed 227th, and 14th among Canadian universities.
