    1. Advances in Ocular Imaging in Glaucoma (Textbook)

      Advances in Ocular Imaging in Glaucoma (Textbook)

      Serving as a practical guide to the ocular imaging modalities that are currently available to eye care providers for the care of glaucoma patients, this book provides information on advances in ocular imaging and their applications in the diagnosis and management of glaucoma. Each chapter introduces the imaging modality, highlight its strengths and weaknesses for clinical care, and discuss its integration into the clinical examination and decision-making process. The chapters also provide an in-depth description of the interpretation of images from each imaging modality. When appropriate, the chapters will summarize past and ongoing research and propose future research directions and ...

    2. Effect of Scan Size on Glaucoma Diagnostic Performance Using OCT Angiography En Face Images of the Radial Peripapillary Capillaries

      Effect of Scan Size on Glaucoma Diagnostic Performance Using OCT Angiography En Face Images of the Radial Peripapillary Capillaries

      Precis: When comparing 4.5×4.5 mm to 6.0×6.0 mm optical coherence tomography angiography scans of the radial peripapillary capillaries (RPCs) for glaucoma diagnostic capability, there was a trend of 4.5 scans outperforming 6.0 scans, especially for inferior, nasal, and superior quadrants. Objectives: The main purpose of this study was to compare diagnostic ability of peripapillary vessel parameters from 4.5×4.5 mm (4.5) and 6.0×6.0 mm (6.0) spectral-domain optical coherence tomography angiography scans of the RPC in detecting primary open-angle glaucoma from nonglaucoma eyes. Methods: Consecutive patients ...

    3. Diagnostic Performance of Macular Versus Peripapillary Vessel Parameters by Optical Coherence Tomography Angiography for Glaucoma

      Diagnostic Performance of Macular Versus Peripapillary Vessel Parameters by Optical Coherence Tomography Angiography for Glaucoma

      Purpose : To compare the diagnostic ability of the vessel parameters in macular and peripapillary regions measured using spectral-domain optical coherence tomography angiography (SD-OCTA) in differentiating primary open-angle glaucoma (POAG) from healthy eyes. Methods : POAG patients and healthy subjects underwent 6 × 6-mm scans centered on the macula and optic nerve head. Commercially available automatic segmentation created en face images from SD-OCTA of the superficial retinal layer (SRL) of the macular (m) and peripapillary (cp) regions. Vessel area density (VAD), vessel skeleton density (VSD), vessel complexity index (VCI), and flux were calculated. Area under curve (AUC) statistics controlled for age and intereye ...

    4. Peripapillary microvasculature in the retinal nerve fiber layer in glaucoma by optical coherence tomography angiography: focal structural and functional correlations and diagnostic performance

      Peripapillary microvasculature in the retinal nerve fiber layer in glaucoma by optical coherence tomography angiography: focal structural and functional correlations and diagnostic performance

      Purpose: To quantify peripapillary microvasculature within the retinal nerve fiber layer (RNFL) in primary open-angle glaucoma (POAG) and normal eyes, determine association of perfusion parameters with structural and functional measures, and report diagnostic accuracy of perfusion parameters. Patients and methods: POAG and normal patients underwent 6×6 mm2 optic nerve head scans (Angioplex optical coherence tomography angiography [OCTA]; Cirrus HD-OCT 5000) and Humphrey Field Analyzer II-i 24-2 visual field (VF) testing. Prototype software performed semiautomatic segmentation to create RNFL en face images and quantified vessel area density (VAD), vessel skeleton density (VSD), and vessel complexity index (VCI) in the optic ...

    5. Structural and Functional Associations of Macular Microcirculation in the Ganglion Cell-inner Plexiform Layer in Glaucoma Using Optical Coherence Tomography Angiography

      Structural and Functional Associations of Macular Microcirculation in the Ganglion Cell-inner Plexiform Layer in Glaucoma Using Optical Coherence Tomography Angiography

      Purpose: To quantify retinal microvasculature within the macular ganglion cell-inner plexiform layer (GCIPL) in primary open angle glaucoma (POAG) and normal eyes, determine association of vessel parameters with structural and functional measures, and report diagnostic accuracy of vessel parameters. Methods: POAG and normal patients underwent 6▒mm×6▒mm macula scans (Angioplex TM optical coherence tomography angiography [OCTA]; Cirrus TM HD-OCT 5000); and Humphrey Field Analyzer II-i 24-2 visual field (VF) (Zeiss, Dublin, CA). Prototype software performed semi-automatic segmentation to create GCIPL en face images, and quantified vessel area density (VAD), vessel skeleton density (VSD), and vessel complexity index (VCI ...
