    3. Oregon Health & Science University Receives NIH grant to study Dynamic Changes in the Chick Developing Heard in Response to Altered Hemodyanmics

      Oregon Health & Science University Receives NIH grant to study Dynamic Changes in the Chick Developing Heard in Response to Altered Hemodyanmics

      Oregon Health & Science University received at 2014 NIH grant for $404,161 to study Dynamic Changes in the Chick Developing Heard in Response to Altered Hemodyanmics. The principal investigator is Sandra Rugonyi. The program began in 2008 and ends in 2015. Below is a summary of the proposed work. About 1% newborn babies have congenital heart disease (CHD), the leading cause of death among children. The majority of CHD cases are believed not to have a genetic cause. Other factors, such as abnormal blood flow during embryonic and fetal stages can lead to heart malformations and thus CHD through poorly ...

    7. Quantification Of Local Circulation With Oct Angiography

      Quantification Of Local Circulation With Oct Angiography

      Impaired intraocular blood flow within vascular beds in the human eye are associated with certain ocular diseases including, for example, glaucoma, diabetic retinopathy and age-related macular degeneration. A reliable method to quantify blood flow in one or more of the various intraocular vascular beds could provide insight into the vascular component of ocular disease pathophysiology.

    8. Predicting Transepithelial Phototherapeutic Keratectomy Outcomes Using Fourier Domain Optical Coherence Tomography

      Predicting Transepithelial Phototherapeutic Keratectomy Outcomes Using Fourier Domain Optical Coherence Tomography

      PURPOSE:: The aim of this study was to use Fourier domain optical coherence tomography to predict transepithelial phototherapeutic keratectomy outcomes. METHODS:: This is a prospective case series. Subjects with anterior stromal corneal opacities underwent an excimer laser phototherapeutic keratectomy (PTK) combined with a photorefractive keratectomy using the VISX S4 excimer laser (AMO, Inc, Santa Ana, CA). Preoperative and postoperative Fourier domain optical coherence tomography images were used to develop a simulation algorithm to predict treatment outcomes. Main outcome measures included preoperative and postoperative uncorrected distance visual acuities and corrected distance visual acuity. RESULTS:: Nine eyes of 8 patients were treated ...

    9. NON-INVASIVE 3D Imaging And Measuring Of Anterior Chamber Angle Of The Eye

      NON-INVASIVE 3D Imaging And Measuring Of Anterior Chamber Angle Of The Eye

      Embodiments of OCT measurement and analysis techniques described herein enable precise 3D anterior chamber angle measurement from major, pertinent landmarks in the eye. Such techniques result in a more reliable, quantifiable angle measurement technique that is both non-invasive and non- contact in nature, thereby improving clinical practicality, while improving patient comfort and care.

    10. Changes in cochlear blood flow in mice due to loud sound exposure measured with Doppler optical microangiography and laser Doppler flowmetry

      Changes in cochlear blood flow in mice due to loud sound exposure measured with Doppler optical microangiography and laser Doppler flowmetry

      In this work we determined the contributions of loud sound exposure (LSE) on cochlear blood flow (CoBF) in an in vivo anesthetized mouse model. A broadband noise system (20 kHz bandwidth) with an intensity of 119 dB SPL, was used for a period of one hour to produce a loud sound stimulus. Two techniques were used to study the changes in blood flow, a Doppler optical microangiography (DOMAG) system; which can measure the blood flow within individual cochlear vessels, and a laser Doppler flowmetry (LDF) system; which averages the blood flow within a volume (a hemisphere of ~1.5 mm ...

      OPTICAL COHERENCE TOMOGRAPHY–BASED CORNEAL POWER MEASUREMENT AND INTRAOCULAR LENS POWER CALCULATION FOLLOWING LASER VISION CORRECTION (AN AMERICAN OPHTHALMOLOGICAL SOCIETY THESIS)

      power in cataract surgeries after laser vision correction. Methods: Patients with previous myopic laser vision corrections were enrolled in this prospective study from two eye centers. Corneal thickness and power were measured by Fourier-domain OCT. Axial length, anterior chamber depth, and automated keratometry were measured by a partial coherence interferometer. An OCT-based IOL formula was developed. The mean absolute error of the OCT-based formula in predicting postoperative refraction was compared to two regression-based IOL formulae for eyes with previous laser vision correction. Results: Forty-six eyes of 46 patients all had uncomplicated cataract surgery with monofocal IOL implantation. The mean arithmetic ...

  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.
