    3. Reproducibility of Angle Metrics Using the Time-Domain Anterior Segment Optical Coherence Tomography: Intra-Observer and Inter-Observer Variability

      Reproducibility of Angle Metrics Using the Time-Domain Anterior Segment Optical Coherence Tomography: Intra-Observer and Inter-Observer Variability

      Purpose : To evaluate the reproducibility of anterior chamber angle measurements obtained by the Zeiss Visante anterior segment optical coherence tomography (AS-OCT). Methods : Twenty eyes from 20 normal subjects with open anterior chamber angles were studied. The anterior chamber angle was imaged using the Visante AS-OCT. The angle-opening distance (AOD 500, AOD 750), trabercular iris space area (TISA 500, TISA 750) and scleral spur angle (SS angle) at the inferior angle location were measured. All the subjects underwent imaging in a darkened room (1 foot candles measured at the eye). Images were graded in a masked fashion by certified Doheny Image ...

    4. Robot-assisted three-dimensional registration for cochlear implant surgery using a common-path swept-source optical coherence tomography probe

      Robot-assisted three-dimensional registration for cochlear implant surgery using a common-path swept-source optical coherence tomography probe

      Cochlear implantation offers the potential to restore sensitive hearing in patients with severe to profound deafness. However, surgical placement of the electrode array within the cochlea can produce trauma to sensorineural components, particularly if the initial turn of the cochlea is not successfully navigated as the array is advanced. In this work, we present a robot-mounted common-path swept-source optical coherence tomography endoscopic platform for three-dimensional (3-D) optical coherence tomography (OCT) registration and preoperative surgical planning for cochlear implant surgery. The platform is composed of a common-path 600- μ m diameter fiber optic rotary probe attached to a five degrees of freedom ...

    7. Integrated IVUS-OCT for Real-Time Imaging of Coronary Atherosclerosis

      Integrated IVUS-OCT for Real-Time Imaging of Coronary Atherosclerosis

      Accurate assessment of atherosclerotic plaque characteristics and the subsequent tailoring of optimal therapy holds great promise for preventing acute coronary syndromes (ACS) and life-threatening sequelae 1 . Combined use of optical coherence tomography (OCT) and intravascular ultrasound (IVUS) was proposed as a potential method for accurate assessment of plaque characteristics and vulnerability ( 2 , ). However, significant challenges remain in trying to adapt an integrated OCT-IVUS system for clinical applications. We report here a fully integrated intracoronary OCT-IVUS imaging technique to visualize atherosclerotic plaque in living animals and human coronary arteries from cadavers with high resolution and deep penetration capability simultaneously.

    8. Grading of posterior staphyloma with spectral-domain optical coherence tomography and correlation with macular disease

      Grading of posterior staphyloma with spectral-domain optical coherence tomography and correlation with macular disease

      OBJECTIVE: To develop a novel grading system for posterior staphyloma imaged by spectral-domain optical coherence tomography (SD-OCT) and to correlate the incidence of macular disease (vitreomacular traction, epiretinal membrane, macular schisis, lamellar macular hole, and full-thickness macular hole) with each grade. DESIGN: Retrospective chart review. PARTICIPANTS: A total of 150 eyes from 89 patients with posterior staphylomas were examined at Jules Stein Eye Institute, University of California Los Angeles. METHODS: Retrospective analysis of the Cirrus SD-OCT (Carl Zeiss Meditec, Dublin, Calif.) database at a large institution (Jules Stein Eye Institute) was performed and eyes with a posterior staphyloma involving the ...

      Optical coherence tomography 2014

      Optical coherence tomography (OCT) is now widely recognized as the most important retinal imaging technique, replacing angiographic techniques as first-line imaging tools. This has largely been driven by widespread application of retinal pharmacotherapy. As a clinical decision-making tool in that setting, OCT has unparalleled value in delivering important information in a matter of seconds. OCT has dramatically improved the productivity of retinal specialists — ie, the number of patients who can be evaluated in a given clinical session. This special issue on OCT highlights its value as a quantitative tool in assessing retinal anatomy in both health and disease, its power ...

  2. About University of Southern California

    University of Southern California

    University of Southern California is located in Los Angeles, a global center for arts, technology and international trade and is one of the world’s leading private research universities. USC enrolls more international students than any other U.S. university and offers extensive opportunities for internships and study abroad. With a strong tradition of integrating liberal and professional education, USC fosters a vibrant culture of public service and encourages students to cross academic as well as geographic boundaries in their pursuit of knowledge. The Keck School of Medicine is the medical school at the University of Southern California. Founded in 1885 as the USC College of Medicine, it was closed in 1921 and reopened in 1928 as the USC School of Medicine.
