    1. Asymmetry analysis of macular optical coherence tomography angiography in patients with glaucoma and healthy subjects

      Asymmetry analysis of macular optical coherence tomography angiography in patients with glaucoma and healthy subjects
      Background/aims Quantitative analysis of optical coherence tomography angiography (OCT-A) images requires a reproducible approach that accounts for sectoral loss. The objective of this study was to determine whether an index that accounts for both global (perfusion density, PD) and asymmetric loss of perfusion, rather than PD alone, more reliably measures loss of perfusion in patients with glaucoma. Methods We analysed macular OCT-A scans of 95 glaucoma patients and 59 ...

    2. Influence of Bruch’s Membrane Opening Area in Diagnosing Glaucoma with Neuroretinal Parameters from Optical Coherence Tomography

      Influence of Bruch’s Membrane Opening Area in Diagnosing Glaucoma with Neuroretinal Parameters from Optical Coherence Tomography
      Purpose To determine whether the glaucoma diagnostic accuracy of age and Bruchs membrane opening area (BMOA) adjusted normative classifications of minimum rim width (MRW) and retinal nerve fibre layer thickness (RNFLT) is dependent on BMOA, in a European descent population. Design Retrospective, cross-sectional study. Methods We included 182 glaucoma patients and 166 healthy controls for the primary study, and 105 glaucoma patients in a second sample used for a replication ...

    3. OCT-Detected Optic Nerve Head Neural Canal Direction, Obliqueness and Minimum Cross-Sectional Area in Healthy Eyes

      OCT-Detected Optic Nerve Head Neural Canal Direction, Obliqueness and Minimum Cross-Sectional Area in Healthy Eyes
      Purpose To assess anterior scleral canal opening (ASCO) offset relative to Bruchs membrane opening (BMO) (ASCO/BMO offset) so as to determine neural canal direction, obliqueness, and minimum cross-sectional area (NCMCA) in 362 healthy eyes. Design Cross-sectional study Methods After OCT optic nerve head (ONH) and retinal nerve fiber layer thickness (RNFLT) imaging, BMO and ASCO were manually segmented and planes, centroids, size and shape were calculated. Neural canal direction ...

    4. Optical Coherence Tomography Angiography in Mice: Quantitative Analysis After Experimental Models of Retinal Damage

      Optical Coherence Tomography Angiography in Mice: Quantitative Analysis After Experimental Models of Retinal Damage
      Purpose : We implemented optical coherence tomography angiography (OCT-A) in mice to: (1) develop quantitative parameters from OCT-A images, (2) measure the reproducibility of the parameters, and (3) determine the impact of experimental models of inner and outer retinal damage on OCT-A findings. Methods : OCT-A images were acquired with a customized system (Spectralis Multiline OCT2). To assess reproducibility, imaging was performed five times over 1 month. Inner retinal damage was induced ...

    5. Visibility of Optic Nerve Head Structures With Spectral-domain and Swept-source Optical Coherence Tomography

      Visibility of Optic Nerve Head Structures With Spectral-domain and Swept-source Optical Coherence Tomography
      Purpose: To compare the visibility of deep optic nerve head (ONH) structures and the visible area of the anterior surface of the lamina cribrosa (ASLC) with spectral-domain optical coherence tomography (SD-OCT) and swept-source OCT (SS-OCT). Materials and Methods: In total, 33 glaucoma patients were imaged with SD-OCT (Spectralis, 24 radial B-scans centered on the ONH) and SS-OCT (Atlantis, 12 radial and a horizontal and vertical raster scan pattern containing 5 ...

    7. Diagnostic Accuracy of Optical Coherence Tomography and Scanning Laser Tomography for Identifying Glaucoma in Myopic Eyes

      Diagnostic Accuracy of Optical Coherence Tomography and Scanning Laser Tomography for Identifying Glaucoma in Myopic Eyes
      Purpose Ruling out glaucoma in myopic eyes often poses a diagnostic challenge because of atypical optic disc morphology and visual field defects that can mimic glaucoma. We determined whether neuroretinal rim assessment based on Bruch's membrane opening (BMO), rather than conventional optic disc margin (DM)-based assessment or retinal nerve fiber layer (RNFL) thickness, yielded higher diagnostic accuracy in myopic patients with glaucoma. Design Case-control, cross-sectional study. Participants Myopic ...
