    3. Diagnostic Capability of Three-Dimensional Macular Parameters for Glaucoma Using Optical Coherence Tomography Volume Scans

      Diagnostic Capability of Three-Dimensional Macular Parameters for Glaucoma Using Optical Coherence Tomography Volume Scans
      Purpose : To compare the diagnostic capability of three-dimensional (3D) macular parameters against traditional two-dimensional (2D) retinal nerve fiber layer (RNFL) thickness using spectral domain optical coherence tomography. To determine if manual correction and interpolation of B-scans improve the ability of 3D macular parameters to diagnose glaucoma. Methods : A total of 101 open angle glaucoma patients (29 with early glaucoma) and 57 healthy subjects had peripapillary 2D RNFL thickness and 3D ...

    4. Diurnal variation of choriocapillaris vessel flow density in normal subjects measured using optical coherence tomography angiography

      Diurnal variation of choriocapillaris vessel flow density in normal subjects measured using optical coherence tomography angiography
      Background Vessel flow density (VFD) may provide important information regarding perfusion status. Diurnal variation in VFD of choriocapillaris has not been reported in literature. In the index study, optical coherence tomography angiography (OCTA) was used to assess the diurnal variation of the VFD in the choriocapillaris of subjects with no known ocular disease. Methods Fifty eyes with no known ocular disease (25 subjects) were included. OCTA images were acquired using ...

    5. Interpretation of Optical Coherence Tomography Images for Breast Tissue Assessment

      Interpretation of Optical Coherence Tomography Images for Breast Tissue Assessment
      Purpose . Initial studies have shown that optical coherence tomography (OCT) is an effective margin-evaluation tool for breast-conserving surgery, but methods for the interpretation of breast OCT images have not been directly studied. In this work, breast pathologies were assessed with a handheld OCT probe. OCT images and corresponding histology were used to develop guidelines for the identification of breast tissue features in OCT images. Methods . Mastectomy and breast-conserving surgery specimens ...

    6. Super‐achromatic Optical Coherence Tomography Capsule for Ultrahigh‐resolution Imaging of Esophagus

      Super‐achromatic Optical Coherence Tomography Capsule for Ultrahigh‐resolution Imaging of Esophagus
      Endoscopic optical coherence tomography (OCT) is a noninvasive technology allowing for imaging of tissue microanatomies of luminal organs in real time. Conventional endoscopic OCT operates at 1,300 nm wavelength region with a sub‐optimal axial resolution limited to 8‐20 m. In this paper we present the first ultrahigh‐resolution tethered OCT capsule operating at 800 nm and offering about 3‐4 fold improvement of axial resolution (plus enhanced ...

      Surgical instrument and systems with integrated optical sensor
      A surgical instrument has a surgical tool that has a proximal end and a distal end, and an optical sensor that has at least a portion attached to the surgical tool. The surgical tool has a portion that is suitable to provide a reference portion of the surgical tool, and the optical sensor has an end fixed relative to the reference portion of the surgical tool such that the reference ...

    8. Evaluation of Automated Segmentation Algorithms for Optic Nerve Head Structures in Optical Coherence Tomography Images

      Evaluation of Automated Segmentation Algorithms for Optic Nerve Head Structures in Optical Coherence Tomography Images
      Purpose : To compare the identification of optic nerve head (ONH) structures in optical coherence tomography images by observers and automated algorithms. Methods : ONH images in 24 radial scan sets by optical coherence tomography were obtained in 51 eyes of 29 glaucoma patients and suspects. Masked intraobserver and interobserver comparisons were made of marked endpoints of Bruch's membrane opening (BMO) and the anterior lamina cribrosa (LC). BMO and LC positional ...

    9. Leveraging WeChat Social-Media and Messaging Platform to Increase Physical Activity in Chinese Glaucoma Patients

      Leveraging WeChat Social-Media and Messaging Platform to Increase Physical Activity in Chinese Glaucoma Patients
      The positive effects of exercise on ocular health are known, but modern lifestyles have made it difficult to incorporate physical activity into the daily lives of the Chinese population. Recent studies suggest that exercise plays an important role in lowering intraocular pressure (IOP) by protecting retinal ganglion cells (RGCs) in glaucoma patients as well as other potential neuroprotective benefits. Increasing the amount of physical activity within the Chinese glaucoma population ...

    10. Emerging Applications of Optical Coherence Tomography Angiography (OCTA) in neurological research

      Emerging Applications of Optical Coherence Tomography Angiography (OCTA) in neurological research
      Purpose To review the clinical and research value of optical coherence tomography angiography (OCTA) in the field of neurology. Methods Current literature involving OCTA were reviewed through PubMed using the search terms optical coherence tomography angiography, with multiple sclerosis, Alzheimers disease, optic neuropathy, or other closely-related terms. Results OCTA has been applied in research to advance our understanding of the pathobiology of neurological disorders. OCTA-derived blood flow and vessel density ...

    11. Evolution of Visual Outcomes in Clinical Trials for Multiple Sclerosis Disease-Modifying Therapies

      Evolution of Visual Outcomes in Clinical Trials for Multiple Sclerosis Disease-Modifying Therapies
      rom the Section Editor: In March 2018, the Journal of Neuro-Ophthalmology (JNO) launched its inaugural Disease of the Year section, featuring multiple sclerosis (MS). Beginning from a Bench perspective, Meltzner and colleagues presented an elegant overview of the pathogenic mechanisms believed to underpin central nervous system (CNS) injury in MS. To complement these efforts, Backner and Levin highlighted how the afferent visual pathway, as a putative model of CNS inflammation ...

    12. Can Optical Coherence Tomography Be Used to Guide Treatment Decisions in Adult or Pediatric Multiple Sclerosis?

      Can Optical Coherence Tomography Be Used to Guide Treatment Decisions in Adult or Pediatric Multiple Sclerosis?
      Purpose of review With the recognition that neurodegeneration represents the principal substrate of disability in multiple sclerosis (MS), there has been increased strives towards identifying biomarkers for accurately quantifying and tracking neurodegeneration during the disease course. The retina provides an opportune window into the central nervous system (CNS) in MS, with retinal changes in MS reflecting not only local, but also global aspects of neurodegeneration and inflammation operative in the ...
