    2. Vertical and Horizontal Corneal Epithelial Thickness Profiles Determined by Ultrahigh Resolution Optical Coherence Tomography

      Vertical and Horizontal Corneal Epithelial Thickness Profiles Determined by Ultrahigh Resolution Optical Coherence Tomography
      Purpose: To measure vertical and horizontal thickness profiles of the central and peripheral corneal epithelium and determine if daytime changes occur. Methods: Forty eyes of 20 normal subjects were imaged by ultrahigh resolution spectral domain optical coherence tomography to profile the corneal epithelial thickness from the edge of Bowman layer to the central cornea across the vertical and horizontal meridians. Measurements were made at 10:00 AM and again at ...

    3. Repeated Measurements of the Anterior Segment During Accommodation Using Long Scan Depth Optical Coherence Tomography

      Repeated Measurements of the Anterior Segment During Accommodation Using Long Scan Depth Optical Coherence Tomography
      Objectives: The aim was to determine the repeatability of ultralong scan depth spectral-domain optical coherence tomography (SD-OCT) measurements of the ocular anterior segment during accommodation. Methods: The center wavelength of the SD-OCT light source was 840 nm with a bandwidth of 50 nm. The ocular axial resolution of the system was approximately 6.0 [mu]m, and the scan depth was 7.2 mm in air. Twenty eyes of 20 ...

    6. Age-Related Changes in Tear Menisci Imaged by Optical Coherence Tomography

      Age-Related Changes in Tear Menisci Imaged by Optical Coherence Tomography
      Purpose. To determine age-related changes of tear menisci in healthy subjects and to compare tear variables between age-matched normals and dry eye subjects. Methods. Anterior segment optical coherence tomography was used to measure upper and lower tear menisci in healthy subjects (n = 197, 8-83 years) and in age-matched dry eye patients (n = 38, 19-72 years). Measured tear variables included the height and area of the tear meniscus. Tear meniscus volumes ...

    7. SD-OCT with Prolonged Scan Depth for Imaging the Anterior Segment of the Eye

      SD-OCT with Prolonged Scan Depth for Imaging the Anterior Segment of the Eye
      An 840-nm wavelength spectral domain optical coherence tomography (SD-OCT) with prolonged scan depth was developed and mounted onto a conventional slit lamp for imaging the anterior segment of the eye. X-Y cross aiming was applied to align the SD-OCT scanning position during imaging. An internal fixation target displayed on a miniature LCD monitor was provided. The SD-OCT instrument had an axial resolution of 6 µm and a prolonged scan depth ...

    8. Detection of Magnetic Particles in Live DBA/2J Mouse Eyes Using Magnetomotive Optical Coherence Tomography

      Detection of Magnetic Particles in Live DBA/2J Mouse Eyes Using Magnetomotive Optical Coherence Tomography
      Objectives: To demonstrate in vivo molecular imaging of the eye using spectral-domain magnetomotive optical coherence tomography (MMOCT).Methods: A custom-built, high-speed, and high-resolution MMOCT was developed for imaging magnetic particle-coupled molecules in living mouse eyes by applying an external dynamic magnetic field gradient during optical coherence tomography (OCT) scanning. The magnetomotive signals were tested in vitro by scanning magnetic beads embedded within an agarose gel (1.5%) and in vivo ...

    9. Improving image segmentation performance and quantitative analysis via a computer-aided grading methodology for optical coherence tomography retinal image analysis

      Improving image segmentation performance and quantitative analysis via a computer-aided grading methodology for optical coherence tomography retinal image analysis
      We demonstrate quantitative analysis and error correction of optical coherence tomography (OCT) retinal images by using a custom-built, computer-aided grading methodology. A total of 60 Stratus OCT (Carl Zeiss Meditec, Dublin, California) B-scans collected from ten normal healthy eyes are analyzed by two independent graders. The average retinal thickness per macular region is compared with the automated Stratus OCT results. Intergrader and intragrader reproducibility is calculated by Bland-Altman plots of ...

    10. Entire Contact Lens Imaged In Vivo and In Vitro With Spectral Domain Optical Coherence Tomography

      Objectives: To demonstrate the capability of directly visualizing the entire ocular surface and the entire contact lens on the eye using spectral domain optical coherence tomography (SD-OCT).Methods: A custom-built, high-speed, and high-resolution SD-OCT was developed with extended scan depth and width. The eye was imaged before and after wearing a toric soft contact lens (PureVision; Bausch & Lomb). A lubricant eye drop (Soothe; Bausch & Lomb) was instilled in the eye to enhance the image contrast on ...
