    2. 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 ...

    4. 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 ...

    5. 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 ...

    7. Steps to Measurement Floor of an Optical Microangiography Device in Glaucoma

      Steps to Measurement Floor of an Optical Microangiography Device in Glaucoma
      Purpose To compare dynamic ranges and steps to measurement floors of peripapillary and macular metrics from a complex signal-based optical microangiography (OMAG C ) optical coherence tomography angiography (OCTA) device for glaucoma with those of OCT measurements. Design Cross-sectional study. Methods Imaging of 252 eyes from 173 glaucoma subjects and 123 eyes from 92 non-glaucoma subjects from a glaucoma clinic was quantified using custom and commercial software. Metrics from OCT (retinal ...

    8. The Effect of Medical Lowering of Intraocular Pressure on Peripapillary and Macular Blood Flow as Measured by Optical Coherence Tomography Angiography in Treatment-naïve Eyes

      The Effect of Medical Lowering of Intraocular Pressure on Peripapillary and Macular Blood Flow as Measured by Optical Coherence Tomography Angiography in Treatment-naïve Eyes
      Prcis: Reduction of intraocular pressure by latanoprost in treatment-nave eyes is significantly correlated to an increase in vessel density at the optic nerve head. Purpose: To evaluate the effect of topical latanoprost on ocular microvasculature using optical coherence tomography angiography (OCTA). Patients and methods: In this prospective case-control study, 26 eyes from 18 treatment-nave subjects in whom prostaglandin analogue (PGA) latanoprost 0.005% was initiated, were included as cases. In ...

    9. Assessing accommodative presbyopic biometric changes of the entire anterior segment using single swept-source OCT image acquisitions

      Assessing accommodative presbyopic biometric changes of the entire anterior segment using single swept-source OCT image acquisitions
      Background/Objectives To evaluate biometric changes throughout the anterior chamber during accommodation and presbyopia using single image acquisition swept-source anterior-segment optical coherence tomography (AS-OCT). Subject/Methods Anterior-segment images were obtained using a new swept-source AS-OCT device (ANTERION, Heidelberg Engineering) from healthy volunteers ( n =71) across two centers in this prospective observational case series. In one image acquisition, cornea through posterior lens, including the ciliary muscle on both sides of the ...

    10. Past, present and future role of retinal imaging in neurodegenerative disease

      Retinal imaging technology is rapidly advancing and can provide ever-increasing amounts of information about the structure, function and molecular composition of retinal tissue in humans in vivo . Most importantly, this information can be obtained rapidly, non-invasively and in many cases using Food and Drug Administration-approved devices that are commercially available. Technologies such as optical coherence tomography have dramatically changed our understanding of retinal disease and in many cases have significantly ...

      ROSE: A Retinal OCT-Angiography Vessel Segmentation Dataset and New Model
      Optical Coherence Tomography Angiography (OCTA) is a non-invasive imaging technique that has been increasingly used to image the retinal vasculature at capillary level resolution. However, automated segmentation of retinal vessels in OCTA has been under-studied due to various challenges such as low capillary visibility and high vessel complexity, despite its significance in understanding many vision-related diseases. In addition, there is no publicly available OCTA dataset with manually graded vessels for ...
