    2. Use of Optical Coherence Tomography by Nonexpert Personnel as a Screening Approach for Glaucoma

      Use of Optical Coherence Tomography by Nonexpert Personnel as a Screening Approach for Glaucoma
      Purpose: This pilot study was conducted to assess optical coherence tomography (OCT) as a screening tool for glaucoma when used by nonexpert personnel. Methods: This prospective case-control study included 54 patients with open-angle glaucoma and 54 age-matched comparison individuals. Optovue iVue SD-OCT imaging was performed by nonprofessional photographers on undilated patients. The sensitivity, specificity, negative predictive value, and positive predictive value of iVue scan parameters for detecting open-angle glaucoma were ...

    3. Systems and methods for ocular anterior segment tracking, alignment, and dewarping using optical coherence tomography

      Systems and methods for ocular anterior segment tracking, alignment, and dewarping using optical coherence tomography
      The present application discloses methods and systems to track the anterior segment while establishing a position of the delay which will permit good control of the placement of anterior segment structures. This allows accurate dewarping by maximizing the amount of corneal surface that is imaged as well as reducing or eliminating overlap between real and complex conjugate images present in frequency-domain optical coherence tomography. A method to dewarp surfaces given ...

    4. Complex signal-based optical coherence tomography angiography enables in vivo visualization of choriocapillaris in human choroid

      Complex signal-based optical coherence tomography angiography enables in vivo visualization of choriocapillaris in human choroid
      The choriocapillaris (CC) plays an essential role in maintaining the normal functions of the human eye. There is increasing interest in the community to develop an imaging technique for visualizing the CC, yet this remains underexplored due to technical limitations. We propose an approach for the visualization of the CC in humans via a complex signal-based optical microangiography (OMAG) algorithm, based on commercially available spectral domain optical coherence tomography (SD-OCT ...

      Optical Coherence Tomography Angiography Macular and Peripapillary Vessel Perfusion Density in Healthy Subjects, Glaucoma Suspects, and Glaucoma Patients
      Purpose : To evaluate macular and peripapillary vessel perfusion density (VD) in glaucoma suspects (GS) and glaucoma patients; to correlate ganglion cellinner plexiform layer (GCIPL) and retinal nerve fiber layer (RNFL) thicknesses with macular and peripapillary VD; and to evaluate the diagnostic accuracy of the structural and vascular parameters. Methods : A consecutive series of GS, glaucoma patients, and healthy subjects was prospectively recruited from July 1, 2016, to January 31, 2017 ...

    8. Retinal Fluid Segmentation and Detection in Optical Coherence Tomography Images using Fully Convolutional Neural Network

      Retinal Fluid Segmentation and Detection in Optical Coherence Tomography Images using Fully Convolutional Neural Network
      As a non-invasive imaging modality, optical coherence tomography (OCT) can provide micrometer-resolution 3D images of retinal structures. Therefore it is commonly used in the diagnosis of retinal diseases associated with edema in and under the retinal layers. In this paper, a new framework is proposed for the task of fluid segmentation and detection in retinal OCT images. Based on the raw images and layers segmented by a graph-cut algorithm, a ...

    9. Measurement of Optic Disc Cup Surface Depth Using Cirrus HD-OCT

      Measurement of Optic Disc Cup Surface Depth Using Cirrus HD-OCT
      Purpose: To introduce the measurement method of optic disc cup surface depth using spectral-domain optical coherence tomography (SD-OCT) and then evaluate the rates of cup surface depression at three different stages of glaucoma. Methods: We retrospectively identified 52 eyes with preperimetric glaucoma, 56 with mild-or-moderate glaucoma and 50 with severe glaucoma and followed them for at least 48 months. Eyes were imaged using SD-OCT (Cirrus(TM) HD-OCT) at 12-month intervals ...

    10. Swept source interferometric imaging systems and methods

      Swept source interferometric imaging systems and methods
      Embodiments herein include swept-source interferometric imaging systems employing arbitrary sweep patterns in which a swept-source is swept over a continuous spectral range where the variation of wavelength over time is noncontinuous. Embodiments include sweep patterns that result in reduction of signals from moving scatterers and where the sweep is synchronized with the dead time of the camera.

    11. Efficient interferometer designs for optical coherence tomography

      Efficient interferometer designs for optical coherence tomography
      Efficient interferometer designs for optical coherence tomography (OCT) systems are presented. One example interferometer design includes two polarization dependent beamsplitters and a non-polarization dependent combiner. The first polarization dependent beamsplitter transmits light in a first polarization state to a sample arm of the OCT system and transmits light in a second polarization state different from the first polarization state to a reference arm of the system. The second polarization dependent ...

    12. Evaluation of optical coherence tomographic data prior to segmentation

      Evaluation of optical coherence tomographic data prior to segmentation
      An efficient method of evaluating the level of contrast of an OCT dataset is presented. The method develops a metric to segregate useful and not-so-useful data in one or more OCT B-scans, in order to reduce spurious subsequent analyses of the data by downstream segmentation algorithms. It is designed to be fast and efficient and is applied to determining autofocus of an OCT instrument real-time and in identifying a real ...

    13. Optical coherence tomography findings in methanol toxicity

      Optical coherence tomography findings in methanol toxicity
      Background Methanol toxicity poses a significant public health problem in developing countries, and in Southeast Asia, where the most common source of poisoning is via adulterated liquor in local drinks. Methanol toxicity can have devastating visual consequences and retinal specialists should be aware of the features of this toxic optic neuropathy. The authors report a case of severe systemic methanol toxicity and relatively mild optic neuropathy demonstrating unique retinal changes ...
