    2. Repeatability of Choroidal Thickness Measurements on Enhanced Depth Imaging OCT using Different Posterior Boundaries

      Repeatability of Choroidal Thickness Measurements on Enhanced Depth Imaging OCT using Different Posterior Boundaries
      Purpose To assess the reliability of manual choroidal thickness measurements by comparing different posterior boundary definitions of the choroidal-scleral junction on enhanced depth imaging optical coherence tomography (EDI-OCT). Design Reliability analysis Methods Two graders marked the choroidal-scleral junction with segmentation software using different posterior boundaries: 1) the outer border of the choroidal vessel lumen, 2) the outer border of the choroid stroma, and 3) the inner border of the sclera ...

    3. Development of Swept Source Optical Coherence Tomography and Adaptive Optics Scanning Laser Ophthalmoscopy: Improved Imaging Speed and Handheld Applications (Thesis)

      Development of Swept Source Optical Coherence Tomography and Adaptive Optics Scanning Laser Ophthalmoscopy: Improved Imaging Speed and Handheld Applications (Thesis)
      Optical coherence tomography (OCT) is a noninvasive three-dimensional interferometric imaging technique capable of achieving micrometer scale resolution. It is now a standard of care in ophthalmology, where it is used to improve the accuracy of early diagnosis, to better understand the source of pathophysiology, and to monitor disease progression and response to therapy. In particular, retinal imaging has been the most prevalent clinical application of OCT, but researchers and companies ...

    5. Systems and methods of angle-resolved low coherence interferometry based optical correlation

      Systems and methods of angle-resolved low coherence interferometry based optical correlation
      Systems and methods of angle-resolved low coherence interferometry based optical correlation are disclosed. According to an aspect, a method includes directing a sample beam towards a sample for producing a scattered sample beam from the sample. The method also includes receiving the scattered sample beam at a multitude of scattering angles in at least two directions. Further, the method includes cross-correlating the scattered sample beam with a reference beam to ...

    6. Novel microscope-integrated stereoscopic heads-up display for intrasurgical optical coherence tomography

      Novel microscope-integrated stereoscopic heads-up display for intrasurgical optical coherence tomography
      Intra-operative optical coherence tomography (OCT) requires a display technology which allows surgeons to visualize OCT data without disrupting surgery. Previous research and commercial intrasurgical OCT systems have integrated heads-up display (HUD) systems into surgical microscopes to provide monoscopic viewing of OCT data through one microscope ocular. To take full advantage of our previously reported real-time volumetric microscope-integrated OCT (4D MIOCT) system, we describe a stereoscopic HUD which projects a stereo ...

    7. Choroidal Thickness and En Face Optical Coherence Tomography Imaging in Autoimmune Retinopathy

      Choroidal Thickness and En Face Optical Coherence Tomography Imaging in Autoimmune Retinopathy
      A 57-year-old white woman developed autoimmune retinopathy (AIR) in both eyes associated with bilateral autoimmune sensorineural hearing loss. Laboratory testing was positive for 68kDa (heat-shock protein) and 136kDa (human interstitial retinoid-binding protein). Extensive cancer screening was negative. Spectral-domain optical coherence tomography enhanced depth imaging demonstrated a markedly thickened choroid in both eyes. En face imaging showed a distinctive pattern of granular hyperreflective foveal dots. The concurrent sensorineural hearing loss was ...

    8. Prevalence of vitreomacular adhesion: an optical coherence tomography analysis in the retina clinic setting

      Prevalence of vitreomacular adhesion: an optical coherence tomography analysis in the retina clinic setting
      Purpose: The aims of this study were to determine the prevalence of vitreomacular adhesion (VMA) in a random sample of clinical patients at three US retina clinics and to assess comorbid retinal conditions, ocular diseases, prior treatment history, and other medical histories. Patients and methods: This observational, retrospective cohort study was based on patients from the Doheny Eye Centers, Duke Eye Center, and Tufts Medical Center who received a bilateral ...

    9. Analyzing spatial correlations in tissue using angle-resolved low coherence interferometry measurements guided by co-located optical coherence tomography

      Analyzing spatial correlations in tissue using angle-resolved low coherence interferometry measurements guided by co-located optical coherence tomography
      Angle-resolved low coherence interferometry (a/LCI) is an optical technique used to measure nuclear morphology in situ . However, a/LCI is not an imaging modality and can produce ambiguous results when the measurements are not properly oriented to the tissue architecture. Here we present a 2D a/LCI system which incorporates optical coherence tomography imaging to guide the measurements. System design and characterization are presented, along with example cases which ...

  2. About Duke University

    Duke University

    Duke University is a private research university located in Durham, North Carolina, USA. Duke University Medical CenterFor more than 75 years, our community of scholars and students has been devoted to understanding the causes, prevention and treatment of human disease. Duke University Eye Center is part of the Medical School.  Duke University's Pratt School of Engineering established The Fitzpatrick Center for Photonics and Communications Systems in December 2000 to help turn North Carolina into a "photon forest" where research and development in photonics would create the kind of technological advance and economic growth found in California's Silicon Valley.
