    2. Advanced Imaging of the Biliary System and Pancreas

      Advanced Imaging of the Biliary System and Pancreas
      Despite advances in noninvasive techniques for imaging the pancreaticobiliary system, several disease processes including indeterminate biliary strictures as well as neuroendocrine tumors, inflammatory pseudotumors, and complex cysts of the pancreas remain difficult to characterize. New endoscopic imaging technologies have emerged to address these challenges. Cholangioscopy and intraductal ultrasound (IDUS) are powerful tools to characterize subtle biliary concretions and strictures. Confocal Laser Endomicroscopy (CLE) and Optical Coherence Tomography (OCT) are emerging ...

    3. OCTA Derived Vessel Skeleton Density Versus Flux and Their Associations With Systemic Determinants of Health

      OCTA Derived Vessel Skeleton Density Versus Flux and Their Associations With Systemic Determinants of Health
      Purpose: To examine the associations of optical coherence tomography angiography (OCTA)-derived retinal capillary flux with systemic determinants of health. Methods: This is a cross-sectional study of subjects recruited from the African American Eye Disease Study. A commercially available swept-source (SS)-OCTA device was used to image the central 3 3 mm macular region. Retinal capillary perfusion was assessed using vessel skeleton density (VSD) and flux. Flux approximates the number ...

    4. Wedge Defects on Optical Coherence Tomography Angiography of the Peripapillary Retina in Glaucoma

      Wedge Defects on Optical Coherence Tomography Angiography of the Peripapillary Retina in Glaucoma
      Precis: Among subjects with glaucoma, wedge-shaped defects on optical coherence tomography angiography were associated with disc hemorrhages, paracentral visual field defects, increased cup-to-disc ratio, and thinner retinal nerve fiber layer. Purpose: To examine determinants of wedge defects on peripapillary optical coherence tomography angiography (OCTA) in glaucoma. Methods: 278 eyes of 186 subjects with mild to severe primary open angle glaucoma (POAG) underwent 66 spectral domain-OCTA imaging of the superficial peripapillary ...

    6. Optimal number and orientation of anterior segment OCT images to measure ocular biometric parameters in angle closure eyes: the Chinese American Eye Study

      Optimal number and orientation of anterior segment OCT images to measure ocular biometric parameters in angle closure eyes: the Chinese American Eye Study
      Purpose: To assess the optimal number and orientation of anterior segment optical coherence tomography (AS-OCT) images for accurately measuring ocular biometric parameters in angle closure eyes. Methods: Subjects with angle closure, defined as 3 quadrants of non-visible pigmented trabecular meshwork on static gonioscopy, were selected from the Chinese American Eye Study. Mean angle opening distance (AOD500) was calculated using four images (0-180, 45-225, 90-270 and 135-315 meridians) from one eye ...

    8. Endolymphatic Hydrops is a Marker of Synaptopathy Following Traumatic Noise Exposure

      Endolymphatic Hydrops is a Marker of Synaptopathy Following Traumatic Noise Exposure
      After acoustic trauma, there can be loss of synaptic connections between inner hair cells and auditory neurons in the cochlea, which may lead to hearing abnormalities including speech-in-noise difficulties, tinnitus, and hyperacusis. We have previously studied mice with blast-induced cochlear synaptopathy and found that they also developed a build-up of endolymph, termed endolymphatic hydrops. In this study, we used optical coherence tomography to measure endolymph volume in live CBA/CaJ ...

    10. Optical Coherence Tomography Angiography-Derived Flux As a Measure of Physiological Changes in Retinal Capillary Blood Flow

      Optical Coherence Tomography Angiography-Derived Flux As a Measure of Physiological Changes in Retinal Capillary Blood Flow
      Purpose: To compare optical coherence tomography angiography (OCTA)-derived flux with conventional OCTA measures of retinal vascular density in assessment of physiological changes in retinal blood flow. Methods: Healthy subjects were recruited, and 3 3-mm2 fovea-centered scans were acquired using commercially available swept-source OCTA (SS-OCTA) while participants were breathing room air, 100% O2, or 5% CO2. Retinal perfusion was quantified using vessel area density (VAD) and vessel skeleton density (VSD ...

    11. In vivo functional imaging of the human middle ear with a hand-held optical coherence tomography device

      In vivo functional imaging of the human middle ear with a hand-held optical coherence tomography device
      We describe an optical coherence tomography and vibrometry system designed for portable hand-held usage in the otology clinic on awake patients. The system provides clinically relevant point-of-care morphological imaging with 14-44 m resolution and functional vibratory measures with sub-nanometer sensitivity. We evaluated various new approaches for extracting functional information including a multi-tone stimulus, a continuous chirp stimulus, and alternating air and bone stimulus. We also explored the vibratory response over ...
