    6. The Use of Spectral-Domain Optical Coherence Tomography to Detect Glaucoma Progression

      The Use of Spectral-Domain Optical Coherence Tomography to Detect Glaucoma Progression
      Detection of progression and measurement of rates of change is at the core of glaucoma management, and the use of Spectral Domain Optical Coherence Tomography (SD-OCT) has significantly improved our ability to evaluate change in the disease. In this review, we critically assess the existing literature on the use of SD-OCT for detecting glaucoma progression and estimating rates of change. We discuss aspects related to the reproducibility of measurements, their ...

    7. Spectral-Domain Optical Coherence Tomography for Glaucoma Diagnosis

      Spectral-Domain Optical Coherence Tomography for Glaucoma Diagnosis
      Identification of structural damage to the optic nerve and retinal nerve fiber layer (RNFL) is an essential component of diagnosis and management of glaucoma. The introduction of spectral-domain OCT (SD-OCT) has allowed objective quantification of damage to these structures with unprecedented resolution. In addition, recent attention has been directed towards imaging the macular area for quantifying loss of neural tissue caused by the disease. Many studies have evaluated and compared ...

      Diagnostic Ability of Macular Ganglion Cell Inner Plexiform Layer Measurements in Glaucoma Using Swept Source and Spectral Domain Optical Coherence Tomography
      Purpose To evaluate the diagnostic ability of macular ganglion cell and inner plexiform layer measurements in glaucoma, obtained using swept source (SS) and spectral domain (SD) optical coherence tomography (OCT) and to compare to circumpapillary retinal nerve fiber layer (cpRNFL) thickness measurements. Methods The study included 106 glaucomatous eyes of 80 subjects and 41 eyes of 22 healthy subjects from the Diagnostic Innovations in Glaucoma Study. Macular ganglion cell and ...

    9. Diagnostic ability of retinal nerve fiber layer imaging by swept source optical coherence tomography in glaucoma

      Diagnostic ability of retinal nerve fiber layer imaging by swept source optical coherence tomography in glaucoma
      Purpose To evaluate the diagnostic accuracies of swept-source optical coherence tomography (OCT) wide-angle and peripapillary retinal nerve fiber layer (RNFL) thickness measurements for glaucoma detection. Design Cross-sectional case-control study. Methods In this study we enrolled 144 glaucomatous eyes of 106 subjects and 66 eyes of 42 healthy subjects from the Diagnostic Innovations in Glaucoma Study. Glaucoma was defined by the presence of repeatable abnormal standard automated perimetry results and/or ...

    10. Assessment of Optic Nerve Head Drusen Using Enhanced Depth Imaging and Swept Source Optical Coherence Tomography

      Assessment of Optic Nerve Head Drusen Using Enhanced Depth Imaging and Swept Source Optical Coherence Tomography
      Background: Optic nerve head drusen (ONHD) are calcific deposits buried or at the surface of the optic disc. Although ONHD may be associated with progressive visual field defects, the mechanism of drusen-related field loss is poorly understood. Methods for detecting and imaging disc drusen include B-scan ultrasonography, fundus autofluorescence, and optical coherence tomography (OCT). These modalities are useful for drusen detection but are limited by low resolution or poor penetration ...

      Comparison of Different Spectral Domain OCT Scanning Protocols for Diagnosing Preperimetric Glaucoma
      Purpose: To compare the ability of spectral-domain optical coherence tomography (SDOCT) retinal nerve fiber layer (RNFL), optic nerve head (ONH) and macular measurements to detect preperimetric glaucomatous damage. Methods: The study included 142 eyes from 91 patients suspected of having the disease based on the appearance of the optic disc. All eyes had normal visual fields before the imaging session. Forty-eight eyes with progressive glaucomatous damage were included in the ...

      RNFL analysis with spectral-domain optical coherence tomography
      Example of retinal nerve fiber layer (RNFL) analysis with spectral-domain optical coherence tomography (SD-OCT). Top: The right eye shows diffuse RNFL thinning on SD-OCT (A), which is consistent with the neuroretinal rim thinning and enlarged cup seen in the photographs of the optic nerve head (B) and with the visual field loss that is evident on standard automated perimetry (SAP) (C) . Bottom: The left eye shows normal RNFL thickness on ...

    1. Stratus OCT RNFL parameters were able to discriminate eyes with progressing disease by visual fields or optic disc photographs with eyes that remained stable according to these methods, and performed significantly better than [optic nerve head] and macular thickness parameters in detecting change over time.
