    1. Repeatability and Reproducibility of Superficial Macular Retinal Vessel Density Measurements Using Optical Coherence Tomography Angiography En Face Images

      Repeatability and Reproducibility of Superficial Macular Retinal Vessel Density Measurements Using Optical Coherence Tomography Angiography En Face Images
      Importance The repeatability and reproducibility of quantitative metrics from optical coherence tomographic angiography (OCTA) must be assessed before these data can be confidently interpreted in clinical research and practice. Objective To evaluate the repeatability and reproducibility of OCTA-derived retinal vascular quantitative metrics. Design, Setting and Participants In this cross-sectional study, 21 healthy volunteers (42 eyes) and 22 patients with retinal disease (22 eyes), including 14 with age-related macular degeneration, 3 ...

    4. TYPE 3 NEOVASCULARIZATION: Evolution, Association With Pigment Epithelial Detachment, and Treatment Response as Revealed by Spectral Domain Optical Coherence Tomography

      TYPE 3 NEOVASCULARIZATION: Evolution, Association With Pigment Epithelial Detachment, and Treatment Response as Revealed by Spectral Domain Optical Coherence Tomography
      Purpose: To demonstrate the evolution and treatment response of Type 3 neovascularization using spectral domain optical coherence tomography. Methods: We retrospectively analyzed 40 eyes treated with intravitreal anti-vascular endothelial growth factor therapy for Type 3 neovascularization over a variable follow-up period. Results: In 17 eyes, spectral domain optical coherence tomography captured the development of Type 3 neovascularization from punctate hyperreflective foci that preceded any outer retinal defect. The more mature ...

    6. Reproducibility of Angle Metrics Using the Time-Domain Anterior Segment Optical Coherence Tomography: Intra-Observer and Inter-Observer Variability

      Reproducibility of Angle Metrics Using the Time-Domain Anterior Segment Optical Coherence Tomography: Intra-Observer and Inter-Observer Variability
      Purpose : To evaluate the reproducibility of anterior chamber angle measurements obtained by the Zeiss Visante anterior segment optical coherence tomography (AS-OCT). Methods : Twenty eyes from 20 normal subjects with open anterior chamber angles were studied. The anterior chamber angle was imaged using the Visante AS-OCT. The angle-opening distance (AOD 500, AOD 750), trabercular iris space area (TISA 500, TISA 750) and scleral spur angle (SS angle) at the inferior angle ...

    8. Relationship between Visual Acuity and Spectral Domain Optical Coherence Tomography Retinal Parameters in Neovascular Age-Related Macular Degeneration

      Relationship between Visual Acuity and Spectral Domain Optical Coherence Tomography Retinal Parameters in Neovascular Age-Related Macular Degeneration
      Purpose: Relationship between spectral domain optical coherence tomography (SD-OCT) and visual acuity (VA) in neovascular age-related macular degeneration (NVAMD). Procedures: VA and SD-OCTs of 64 treatment-naive eyes with NVAMD were retrospectively collected at baseline and 1 year (n = 30). Retinal and subretinal spaces were manually analyzed. Volume and thickness measurements were correlated with VA. Results: At baseline, lower VA correlated with increased volume of subretinal hyperreflective material (R = 0.4 ...

    9. Drusen Measurements Comparison By Fundus Photograph Manual Delineation Versus Optical Coherence Tomography Retinal Pigment Epithelial Segmentation Automated Analysis

      Drusen Measurements Comparison By Fundus Photograph Manual Delineation Versus Optical Coherence Tomography Retinal Pigment Epithelial Segmentation Automated Analysis
      Purpose: To compare drusen measurements obtained from color fundus and infrared retromode photographs with those derived from spectral-domain optical coherence tomography. Methods: Drusen lesions identified on the planar (color and infrared) imaging modalities were manually segmented by two independent graders using previously described reading center software to produce quantitative measurements of drusen area and number. The corresponding volume Cirrus OCT datasets were analyzed using commercial retinal pigment epithelium analysis algorithms ...
