    2. 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 ...

    3. 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 ...

    4. 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 ...

    5. 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 ...

    7. Laminar Displacement and Prelaminar Tissue Thickness Change after Glaucoma Surgery Imaged with Optical Coherence Tomography

      Laminar Displacement and Prelaminar Tissue Thickness Change after Glaucoma Surgery Imaged with Optical Coherence Tomography
      Purpose: To study changes in lamina cribrosa position and prelaminar tissue thickness (PTT) after surgical intraocular pressure (IOP) reduction in glaucoma patients. Methods: Twenty-two patients (mean age, 71.4 years) were imaged with spectral domain optical coherence tomography (SD-OCT, 24 radial B-scans centered on the optic nerve head) before trabeculectomy or tube shunt implantation. Follow-up images were acquired 1 week, 1 month, 3 and 6 months post-surgery. Bruch's membrane ...

    8. Nerve fiber layer in glaucomatous hemifield loss: a case-control study with time- and spectral-domain optical coherence tomography

      Nerve fiber layer in glaucomatous hemifield loss: a case-control study with time- and spectral-domain optical coherence tomography
      PURPOSE: To evaluate the retinal nerve fiber layer measurements with time-domain (TD) and spectral-domain (SD) optical coherence tomography (OCT), and to test the diagnostic ability of both technologies in glaucomatous patients with asymmetric visual hemifield loss. METHODS: 36 patients with primary open-angle glaucoma with visual field loss in one hemifield (affected) and absent loss in the other (non-affected), and 36 age-matched healthy controls had the study eye imaged with Stratus-OCT ...

    9. Influence of Clinically Invisible, but Optical Coherence Tomography Detected, Optic Disc Margin Anatomy on Neuroretinal Rim Evaluation

      Influence of Clinically Invisible, but Optical Coherence Tomography Detected, Optic Disc Margin Anatomy on Neuroretinal Rim Evaluation
      Purpose: We previously demonstrated that most eyes have regionally variable extensions of Bruch's membrane (BM) inside the clinically identified disc margin (DM) that are clinically and photographically invisible. We studied the impact of these findings on DM and BM opening (BMO) derived neuroretinal rim parameters. Methods: Disc stereo-photography and spectral domain optical coherence tomography (SD-OCT, 24 radial B-scans centred on the optic nerve head) were performed on 30 glaucoma ...

    11. Comparison between confocal scanning laser tomography, scanning laser polarimetry and optical coherence tomography on the ability to detect localised retinal nerve fibre layer defects in glaucoma patients

      Background/aim: To compare the ability of confocal scanning laser tomography (CSLT), scanning laser polarimetry (SLP) and optical coherence tomography (OCT) in recognising localised retinal nerve fibre layer (RNFL) defects. Methods: 51 eyes from 43 patients with glaucoma were identified by two observers as having RNFL defects visible on optic disc photographs. 51 eyes of 32 normal subjects were used as controls. Three masked observers evaluated CSLT, SLP and OCT ...
