    2. Cochlear motion across the reticular lamina implies that it is not a stiff plate

      Cochlear motion across the reticular lamina implies that it is not a stiff plate
      Within the cochlea, the basilar membrane (BM) is coupled to the reticular lamina (RL) through three rows of piezo-like outer hair cells (OHCs) and supporting cells that endow mammals with sensitive hearing. Anatomical differences across OHC rows suggest differences in their motion. Using optical coherence tomography, we measured in vivo and postmortem displacements through the gerbil round-window membrane from approximately the 4047 kHz best-frequency (BF) regions. Our high spatial resolution ...

    5. Comparison of hyperreflective foci in macular edema secondary to multiple etiologies with spectral-domain optical coherence tomography: An observational study

      Comparison of hyperreflective foci in macular edema secondary to multiple etiologies with spectral-domain optical coherence tomography: An observational study
      Background: Hyperreflective foci (HRF) features in macular edema associated with different etiologies may indicate the disease pathogenesis and help to choose proper treatment. The goal of this study is to investigate the retinal microstructural features of macular edema (ME) secondary to multiple etiologies with spectral-domain optical coherence tomography (SD-OCT) and analyze the origin of HRF in ME. Methods: This was a retrospective study. SD-OCT images were reviewed to investigate macular ...

    6. Widefield Swept-Source Optical Coherence Tomography Angiography Findings in Wagner Syndrome

      Widefield Swept-Source Optical Coherence Tomography Angiography Findings in Wagner Syndrome
      Purpose: To describe novel clinical and angiographic findings in Wagner syndrome. Methods: A retrospective case series of three related patients with Wagner syndrome. Patients underwent standard OCT, B-scan ultrasonography, and fluorescein angiography in addition to wide field swept-source OCT angiography (WF SS-OCTA) (PLEX Elite 9000, Carl Zeiss Meditec Inc.). Patients underwent genetic testing for a panel of hereditary vitreoretinopathies. Results: Three related patients with Wagner syndrome were identified. All were ...

    7. Imaging-based Assessment of Choriocapillaris: A Comprehensive Review

      Imaging-based Assessment of Choriocapillaris: A Comprehensive Review
      PURPOSE Over the past two decades, advancements in imaging modalities have significantly evolved the diagnosis and management of retinal diseases. Through these novel platforms, we have developed a deeper understanding of the anatomy of the choroidal vasculature and the choriocapillaris. The recently developed tools such as optical coherence tomography (OCT) and OCT angiography (OCTA) have helped elucidate the pathological mechanisms of several posterior segment diseases. In this review, we have ...

    8. Reproducibility of Neuroretinal Rim Measurements Obtained from High-Density Spectral Domain Optical Coherence Tomography Volume Scans

      Reproducibility of Neuroretinal Rim Measurements Obtained from High-Density Spectral Domain Optical Coherence Tomography Volume Scans
      Purpose: To compare the reproducibility of two-dimensional (2D) peripapillary retinal nerve fiber layer (RNFL) thickness and three-dimensional (3D) neuroretinal rim measurements using spectral domain optical coherence tomography (SDOCT) in normal and glaucoma subjects. Methods: One eye per subject for 27 normal and 40 glaucoma subjects underwent repeat SDOCT RNFL thickness scans and optic nerve volume scans on the same day. From the volume scan, custom software calculated five neuroretinal rim ...

    9. Retinal microvasculature and vasoreactivity changes in hypertension using optical coherence tomography-angiography

      Retinal microvasculature and vasoreactivity changes in hypertension using optical coherence tomography-angiography
      Purpose: To evaluate the retinal vasculature and vasoreactivity of patients with hypertension (HTN) using spectral domain optical coherence tomography angiography (SD-OCTA). Methods: Patients with and without a diagnosis of HTN were included in this cross-sectional observational study. All eyes were imaged with SD-OCTA using 3 mm 3 mm and 6 mm 6 mm centered on both the fovea and optic disk. A second 6 mm 6 mm scan was taken ...

      Nonperfusion Area and Other Vascular Metrics by Wider Field Swept-Source OCT Angiography as Biomarkers of Diabetic Retinopathy Severity
      Purpose: To study the wider field swept-source optical coherence tomography angiography (WF SS-OCTA) metrics, especially non-perfusion area (NPA), in the diagnosing and staging of DR. Design: Cross-sectional observational study (November 2018-September 2020). Participants: 473 eyes of 286 patients (69 eyes of 49 control patients and 404 eyes of 237 diabetic patients). Methods: We imaged using 6mm6mm and 12mm12mm angiograms on WF SS-OCTA. Images were analyzed using the ARI Network and ...

    12. Juxtapapillary Choroidal Neovascular Membrane as a Complication of Optic Disc Drusen: Multimodal Imaging With Swept Source-Optical Coherence Tomography and Optical Coherence Tomography Angiography

      Juxtapapillary Choroidal Neovascular Membrane as a Complication of Optic Disc Drusen: Multimodal Imaging With Swept Source-Optical Coherence Tomography and Optical Coherence Tomography Angiography
      A 55-year-old Caucasian man presented to the neuro-ophthalmology department for follow-up evaluation due to long-standing bilateral optic nerve head drusen (ONHD). On examination, the BCVA was 20/20-2 in both eyes. Dilated fundus examination revealed extensive ONHD in both eyes, retinal hemorrhages, exudates inferonasal to the macula, and macular edema inferotemporal to the disc margin. Automated visual field testing revealed generalized depression in both eyes. Late phase leakage was observed ...

    13. Cochlear Fluid Spaces and Structures of the Gerbil High-Frequency Region Measured Using Optical Coherence Tomography (OCT)

      Cochlear Fluid Spaces and Structures of the Gerbil High-Frequency Region Measured Using Optical Coherence Tomography (OCT)
      Since it has been difficult to directly observe the morphology of the living cochlea, our ability to infer the mechanical functioning of the living ear has been limited. Nearly all our knowledge about cochlear morphology comes from postmortem tissue that was fixed and processed using procedures that possibly distort the structures and fluid spaces of the organ of Corti. In this study, optical coherence tomography was employed to obtain volumetric ...
