    1. Comparison of Disc Analysis Algorithms Provided by Cirrus OCT and Stereo Optic-disc Photography in Normal and Open Angle Glaucoma Patients

      Comparison of Disc Analysis Algorithms Provided by Cirrus OCT and Stereo Optic-disc Photography in Normal and Open Angle Glaucoma Patients

      Purpose: To compare optic nerve head (ONH) parameters obtained by semi-automated disc analysis of stereo optic-disc photography (ODP) with those by spectral domain optical coherence tomography (SD-OCT) regarding their reproducibility, agreement and relationship with the retinal nerve fiber layer (RNFL) thickness. Patients and methods: In this cross-sectional retrospective study, 91 eyes (50 normal and 41 with open angle glaucoma) from 47 patients were examined. ONH parameters were obtained by ODP and SD-OCT. Agreement and reproducibility were assessed by intra-class correlation coefficients (ICCs). Inter-device agreement and precision were also evaluated. The structural factors related to the ONH measurements by both instruments ...

    2. Comparison of Event-Based Methods Using Optical Coherence Tomography and Automated Perimetry to Detect the Progression of Glaucoma in Patients with Open-Angle Glaucoma

      Comparison of Event-Based Methods Using Optical Coherence Tomography and Automated Perimetry to Detect the Progression of Glaucoma in Patients with Open-Angle Glaucoma

      Background/Aims: To compare event-based methods for estimating the incidence of glaucoma progression using optical coherence tomography (OCT) and automated perimetry and to assess agreement between structural and functional tests for detecting glaucoma progression. Methods: Functional progression of glaucoma was estimated by guided progression analysis (GPA) using a Humphrey field analyzer (HFA), and structural progression was assessed by OCT and defined as the decrease in retinal nerve fiber layer thickness based on test-retest variability data of previous reports on clock-hour and quadrant maps. The level of agreement between structural and functional progression was evaluated using kappa statistics. Results: Fifty eyes ...
