    2. Retinal Nerve Fiber and Optic Disc Morphology in Patients with Human Immunodeficiency Virus Using the Heidelberg Retina Tomography 3

      Retinal Nerve Fiber and Optic Disc Morphology in Patients with Human Immunodeficiency Virus Using the Heidelberg Retina Tomography 3
      Purpose To use novel confocal scanning ophthalmoscopy technology to test hypothesis that HIV-seropositive patients without history of retinitis with a history of a low CD4 count are more likely to have damage to their retinal nerve fiber layer (RNFL) when compared to patients with high CD4 count. In addition, we compared optic disc morphologic changes with glaucoma. Design Cross-sectional study. Participants and Controls 171 patients were divided into four groups ...

      Correlation of Spectral Domain Optical Coherence Tomography Characteristics With Visual Acuity in Eyes With Subfoveal Scarring After Treatment for Wet Age-Related Macular Degeneration
      Purpose: Correlating spectral domain optical coherence tomography characteristics with final best-corrected visual acuity (BCVA) in eyes with subfoveal scarring after treatment for wet age-related macular degeneration. Methods: Seventy-nine eyes from 64 subjects, who developed subfoveal scarring after treatment of wet age-related macular degeneration, were retrospectively studied. Spectral domain optical coherence tomography characteristics were analyzed, including percentage disruption of inner segment/outer segment junction and external limiting membrane, central macular thickness ...

    7. Repeatability and reproducibility of manual choroidal volume measurements using enhanced depth imaging optical coherence tomography

      Repeatability and reproducibility of manual choroidal volume measurements using enhanced depth imaging optical coherence tomography
      Purpose: To evaluate the repeatability and reproducibility of manual choroidal volume (CV) measurements on spectral-domain optical coherence tomography (SD-OCT) using enhanced depth imaging (EDI). Methods: Sixty eyes of 32 patients with or without any ocular chorio-retinal diseases were enrolled prospectively. Thirty-one choroidal scans were performed on each eye centered at the fovea using a raster protocol. Two masked observers demarcated choroidal boundaries using the built-in automated retinal segmentation software on ...

    8. Characterization of Diabetic Microaneurysms by Simultaneous Fluorescein Angiography and Spectral-Domain Optical Coherence Tomography

      Characterization of Diabetic Microaneurysms by Simultaneous Fluorescein Angiography and Spectral-Domain Optical Coherence Tomography
      Purpose To correlate spectral-domain optical coherence tomography (SD-OCT) findings of perfused diabetic microaneurysms with leakage status on fluorescein angiography (FA) using simultaneous FA and SD-OCT. Design Retrospective, observational case series. Methods A total of 173 microaneurysms were analyzed in 50 eyes (14 mild nonproliferative diabetic retinopathy [NPDR]; 22 moderate NPDR; 9 severe NPDR; 5 proliferative diabetic retinopathy) of 40 diabetic patients using simultaneous FA and SD-OCT. The characteristics of microaneurysms ...

    9. Spectral-Domain Optical Coherence Tomography Imaging of Postoperative Scleral Buckles

      Spectral-Domain Optical Coherence Tomography Imaging of Postoperative Scleral Buckles
      Purpose: To describe the appearance on spectral domain optical coherence tomography of the peripheral retina and overlying vitreous after scleral buckling surgery. Methods: Retrospective case series of patients who underwent scleral buckle surgery and had subsequent scanning laser ophthalmoscopy/spectral-domain optical coherence tomography images over the area of buckled retina. Twelve eyes from 11 patients were identified and show a variety of retinal anatomies, vitreous configurations, and clinical applications. Results ...
