    2. Corneal Epithelial Remodeling after LASIK Measured by Fourier-Domain Optical Coherence Tomography

      Corneal Epithelial Remodeling after LASIK Measured by Fourier-Domain Optical Coherence Tomography
      Purpose . To quantify corneal epithelial thickness changes after myopic LASIK by OCT. Methods. Epithelial thickness before and after myopic LASIK were measured by a Fourier-domain OCT system. Average central (within 1mm diameter) and paracentral epithelial thickness (5~6mm diameter) before and after LASIK were compared. Correlation between central epithelial thickness change and laser spherical equivalent setting was evaluated. An epithelial smoothing constant was estimated based on a mathematical model published ...

    3. En face Doppler total retinal blood flow measurement with 70 kHz spectral optical coherence tomography

      En face Doppler total retinal blood flow measurement with 70 kHz spectral optical coherence tomography
      An automated algorithm was developed for total retinal blood flow (TRBF) using 70-kHz spectral optical coherence tomography (OCT). The OCT was calibrated for the transformation from Doppler shift to speed based on a flow phantom. The TRBF scan pattern contained five repeated volume scans ( 2 2 mm ) obtained in 3 s and centered on central retinal vessels in the optic disc. The TRBF was calculated using an en face Doppler ...

    4. Macular Perfusion in Healthy Chinese: An Optical Coherence Tomography Angiogram Study

      Macular Perfusion in Healthy Chinese: An Optical Coherence Tomography Angiogram Study
      Purpose. To investigate macular perfusion in healthy Chinese individuals and examine its dependence on age and sex. Methods. Healthy adult Chinese individuals were recruited. Macular perfusion was measured by spectral-domain optical coherence tomography (OCT) using the split-spectrum amplitude-decorrelation angiography (SSADA) algorithm. The parafoveal flow index and vessel area density as well as the area of the foveal capillary-free zone (CFZ) were quantified. Results. A total of 76 eyes in 45 ...

    5. Optical Coherence Tomography Angiography of Peripapillary Retinal Blood Flow Response to Hyperoxia

      Optical Coherence Tomography Angiography of Peripapillary Retinal Blood Flow Response to Hyperoxia
      Purpose. To measure the change in peripapillary retinal blood flow in response to hyperoxia by using optical coherence tomography (OCT) angiography. Methods. One eye of each healthy human participants (six) was scanned with a commercial high-speed (70 kHz) spectral OCT. Scans were captured twice after 10-minute exposures to normal breathing (baseline) and hyperoxia. Blood flow was detected by the split-spectrum amplitude-decorrelation angiography (SSADA) algorithm. Peripapillary retinal blood flow index and ...

    6. Staging of development in Terrien's degeneration based on corneal curvatures detected by optical coherence tomography

      Staging of development in Terrien's degeneration based on corneal curvatures detected by optical coherence tomography
      Purpose We aimed to explore a new classification system based on the change of focal corneal curvatures and corneal thickness in Terriens corneal degeneration with optical coherence tomography. Methods This was a cross-sectional study. Ninety eyes of 59 patients with Terriens degeneration were examined with slit lamp biomicroscopy, Orbscan II corneal tomography and the Visante OCT system, and were staged according to Svegess classification. Results The ratio of female to ...

    8. First International OCT Angiography Summit, Portland Oregon, July 25, 2015

      First International OCT Angiography Summit, Portland Oregon, July 25, 2015
      The OCT Angiography Summit CME conference introduces the new no-injection, dye-free imaging technology to the clinical audience. OCT angiography detects the intrinsic motion contrast of blood cells and therefore does not require the injection of extrinsic contrast such as fluorescein or ICG dye. This breakthrough technology is capable of three-dimensional imaging of capillary dropout or pathologic vessel growth in the leading cause of blindness: age-related macular degeneration, diabetic retinopathy, and ...

    11. Method and apparatus for ultrahigh sensitive optical microangiography

      Method and apparatus for ultrahigh sensitive optical microangiography
      Embodiments herein provide an ultrahigh sensitive optical microangiography (OMAG) system that provides high sensitivity to slow flow information, such as that found in blood flow in capillaries, while also providing a relatively low data acquisition time. The system performs a plurality of fast scans (i.e., B-scans) on a fast scan axis, where each fast scan includes a plurality of A-scans. At the same time, the system performs a slow ...

  2. About Oregon Health & Science University

    Oregon Health & Science University

    Oregon Health & Science University (OHSU) is a public university in Oregon with a main campus, including three hospitals, in Portland and a smaller campus in Hillsboro. It was formed in 1974 as the University of Oregon Health Sciences Center, combining state dentistry, medicine, and nursing programs into a single center. It was renamed Oregon Health Sciences University in 1981 and took its current name in 2001, as part of a merger with the Oregon Graduate Institute of Science and Technology (OGI) in Hillsboro. In addition, the university has several partnership programs including a joint PharmD Pharmacy program with Oregon State University.
