    2. Off-axis optical coherence tomography imaging of the crystalline lens to reconstruct the gradient refractive index using optical methods

      Off-axis optical coherence tomography imaging of the crystalline lens to reconstruct the gradient refractive index using optical methods
      Earlier studies have shown that the gradient index of refraction (GRIN) of the crystalline lens can be reconstructed in vitro using Optical Coherence Tomography (OCT) images. However, the methodology cannot be extended in vivo because it requires accurate measurements of the external geometry of the lens. Specifically, the posterior surface is measured by flipping the lens so that the posterior lens surface faces the OCT beam, a method that cannot ...

    3. Use of High-Resolution Optical Coherence Tomography in the Surgical Management of Ocular Surface Squamous Neoplasia: A Pilot Study

      Use of High-Resolution Optical Coherence Tomography in the Surgical Management of Ocular Surface Squamous Neoplasia: A Pilot Study
      Purpose To evaluate whether high-resolution optical coherence tomography (HR-OCT) can detect histologic tumor margins of ocular surface squamous neoplasia (OSSN). Methods Eight eyes of 8 patients with OSSN undergoing excision were studied prospectively. Immediately before surgery, the tumor was imaged using a commercially available HR-OCT (Bioptigen/Leica Microsystems, Buffalo Grove, IL) to identify the conjunctival margins of the neoplastic lesion. The tumor borders of the lesion determined by HR-OCT were ...

    5. Variability of manual ciliary muscle segmentation in optical coherence tomography images

      Variability of manual ciliary muscle segmentation in optical coherence tomography images
      Optical coherence tomography (OCT) offers new options for imaging the ciliary muscle allowing directin vivovisualization. However, variation in image quality along the length of the muscle prevents accurate delineation and quantification of the muscle. Quantitative analyses of the muscle are accompanied by variability in segmentation between examiners and between sessions for the same examiner. In processes such as accommodation where changes in muscle thickness may be tens of microns- the ...

    6. High-Resolution Optical Coherence Tomography–Guided Donor Tissue Preparation for Descemet Membrane Endothelial Keratoplasty Using the Reverse Big Bubble Technique

      High-Resolution Optical Coherence Tomography–Guided Donor Tissue Preparation for Descemet Membrane Endothelial Keratoplasty Using the Reverse Big Bubble Technique
      Purpose: The aim of this study was to assess the feasibility of high-resolution spectral domain optical coherence tomography (HR-SDOCT) to guide donor tissue preparation in Descemet membrane endothelial keratoplasty using the reverse big bubble technique. Methods: Three corneoscleral discs were included in this ex vivo experimental study. A 27-G cannula was introduced into each cornea at the periphery by 3 different surgeons. Each surgeon attempted to achieve the ideal depth ...

    8. Dynamic imaging of accommodation by swept-source anterior segment optical coherence tomography

      Dynamic imaging of accommodation by swept-source anterior segment optical coherence tomography
      Purpose To study the accommodation process in normal eyes using a commercially available clinical system based on swept-source anterior segment optical coherence tomography (AS-OCT). Setting Ophthalmology Department, University of Parma, Italy. Design Evaluation of diagnostic technology. Methods Right eyes were analyzed using swept-source AS-OCT (Casia SS-1000). The optical vergence of the internal coaxial fixation target was adjusted during imaging to obtain monocular accommodation stimuli with different amplitudes (0, 3.0 ...

    10. Intraoperative imaging system and apparatus

      Intraoperative imaging system and apparatus
      Systems, methods and apparatuses for intraocular imaging system are disclosed comprising an optical coherence tomography (OCT) system. The OCT system has an imaging range that may enable substantial portions of an eye to be imaged. The OCT system may be coupled to an operation microscope, such that, for example, a surgeon can visualize ocular structures like the human crystalline lens and other ocular structures such as the cornea and/or ...

    11. Structural Correlation Between the Nerve Fiber Layer and Retinal Ganglion Cell Loss in Mice with Targeted Disruption of the Brn3b Gene

      Structural Correlation Between the Nerve Fiber Layer and Retinal Ganglion Cell Loss in Mice with Targeted Disruption of the Brn3b Gene
      Purpose. Mice with a targeted disruption of Brn3b (knockout Brn3b-/-) undergo the loss of a majority of retinal ganglion cells (RGCs) before birth. Spectral domain optical coherence tomography (SD-OCT) allows for the noninvasive examination of Brn3b-/- cellular loss in vivo. Methods. The central retinas of Brn3b-/- and phenotypically wild-type (Brn3b+/+ and Brn3b±) mice were imaged by SD-OCT. The combined nerve fiber layer (NFL) and inner plexiform layer (IPL) were manually ...
