      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 ...

      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 ...

      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 ...

      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 ...

      Ophthalmic laser system integrated with speckle variance optical coherence tomography for real-time temperature monitoring
      A commercial ophthalmic laser system (R;GEN, Lutronic Corp) was integrated with a swept-source optical coherence tomography (OCT) imaging system for real-time tissue temperature monitoring. M-scan OCT images were acquired during laser-pulse radiation, and speckle variance OCT (svOCT) images were analyzed to deduce temporal signal variations related to tissue temperature change from laser-pulse radiation. A phantom study shows that svOCT magnitude increases abruptly after laser pulse radiation and recovered exponentially ...

      Motion-compensated optical coherence tomography using envelope-based surface detection and Kalman-based prediction
      We present an optical coherence tomography (OCT) imaging system that effectively compensates unwanted axial motion with micron-scale accuracy. The OCT system is based on a swept-source (SS) engine (1060-nm center wavelength, 100-nm full-width sweeping bandwidth, and 100-kHz repetition rate), with axial and lateral resolutions of about 4.5 and 8.5 microns respectively. The SS-OCT system incorporates a distance sensing method utilizing an envelope-based surface detection algorithm. The algorithm locates ...

      In vivo high resolution human corneal imaging using full-field optical coherence tomography
      We present the first full-field optical coherence tomography (FFOCT) device capable of in vivo imaging of the human cornea. We obtained images of the epithelial structures, Bowmans layer, sub-basal nerve plexus (SNP), anterior and posterior stromal keratocytes, stromal nerves, Descemets membrane and endothelial cells with visible nuclei. Images were acquired with a high lateral resolution of 1.7 m and relatively large field-of-view of 1.26 mm x 1.26 ...

      Cycloid scanning for wide field optical coherence tomography endomicroscopy and angiography in vivo
      Devices that perform wide field-of-view (FOV) precision optical scanning are important for endoscopic assessment and diagnosis of luminal organ disease such as in gastroenterology. Optical scanning for in vivo endoscopic imaging has traditionally relied on one or more proximal mechanical actuators, limiting scan accuracy and imaging speed. There is a need for rapid and precise two-dimensional (2D) microscanning technologies to enable the translation of benchtop scanning microscopies to in vivo ...

      Real-time optical coherence tomography incorporated in the operating microscope during cataract surgery
      A 55-year-old male presented with reduced vision due to senile cataract. The patient consented to undergo real-time intraoperative anterior segment-optical coherence tomography (AS-OCT) during phacoemulsification with intraocular lens (IOL) implantation. Images were captured at various points during the surgery. The use of AS-OCT incorporated into the surgical microscope was evaluated as an adjunct to cataract surgery. We were able to successfully evaluate, in real-time, wound architecture, the attachment of Descemet ...

      Retinal thickness measured with optical coherence tomography and risk of disability worsening in multiple sclerosis: a cohort study
      Background Most patients with multiple sclerosis without previous optic neuritis have thinner retinal layers than healthy controls. We assessed the role of peripapillary retinal nerve fibre layer (pRNFL) thickness and macular volume in eyes with no history of optic neuritis as a biomarker of disability worsening in a cohort of patients with multiple sclerosis who had at least one eye without optic neuritis available. Methods In this multicentre, cohort study ...
