    2. Vascular Findings In A Small Retinoblastoma Tumor Using OCT-A

      Vascular Findings In A Small Retinoblastoma Tumor Using OCT-A
      Retinoblastoma (RB) is the most common primary intraocular malignancy of children. 1 Improvements in screening tactics and treatment methods have dramatically increased both patient and globe survival. 1,2 Imaging modalities such as fluorescein angiography (FA) have demonstrated retinal vascular abnormalities in both large and small caliber retinal vessels in eyes with retinoblastoma, 1 and optical coherence tomography (OCT) can reveal or confirm otherwise subclinical lesions. 2 OCT angiography (OCT-A ...

    3. Treatment Response in Sympathetic Ophthalmia as Assessed by Widefield OCT Angiography

      Treatment Response in Sympathetic Ophthalmia as Assessed by Widefield OCT Angiography
      The authors report the widefield montage swept-source optical coherence tomography angiography (OCTA) findings in a 36-year-old male with sympathetic ophthalmia and illustrate the presence of multiple small areas of choriocapillaris flow voids that likely correspond to areas of choriocapillaris ischemia. Using sequential imaging, the authors observed that these flow voids improved following initiating of steroid and immunosuppressive therapy and almost completely resolved following 6 months of therapy with corresponding improvement ...

    4. OCT Promising as Clear Point-of-Care Solution

      OCT Promising as Clear Point-of-Care Solution
      Medical devices at the point of care allow clinicians to do what they do best: determine a patients exact condition and a course of treatment. These technologies work best when they fit seamlessly into the provider-patient workflow without a steep learning curve or worry about the underlying scientific principles, and without the high cost seen for so many medical technologies. Optical coherence tomography (OCT) is an imaging technology that has ...

    5. Orbital arteriovenous fistula presenting with choroidal pulsations on optical coherence tomography

      Orbital arteriovenous fistula presenting with choroidal pulsations on optical coherence tomography
      Purpose To describe a case of orbital arteriovenous fistula diagnosed based on choroidal pulsations on optical coherence tomography (OCT). Observations A 69-year-old female originally referred for evaluation of macular degeneration . During acquisition of OCT images, choroidal pulsations of the right eye were noted on the B-scan on the instrument display. The pulsations were not noted on gross or funduscopic examination. Fluorescein angiography was unremarkable. Indocyanine green angiography revealed engorged choroidal ...

    6. Spectral Domain-Optical Coherence Tomography of the Vitreopapillary Interface in Acute Non-Arteritic Anterior Ischemic Optic Neuropathy

      Spectral Domain-Optical Coherence Tomography of the Vitreopapillary Interface in Acute Non-Arteritic Anterior Ischemic Optic Neuropathy
      Purpose To use spectral domain-optical coherence tomography (SD-OCT) to assess whether epipapillary vitreous traction from evolving posterior vitreous detachment (PVD) is mechanistically involved in the pathogenesis of non-arteritic anterior ischemic optic neuropathy (NAION). Design Retrospective cohort study. Methods.Setting Single academic center. Patient or study population Eighty eyes in 74 subjects presenting within 2 weeks of symptom onset of NAION. Intervention or observation procedures SD-OCT imaging of the optic nerve ...

    7. Characterization of Corneal Donor Tissue Lesions by Anterior Segment Optical Coherence Tomography Compared With Eye Bank Technician Slit-Lamp Examination

      Characterization of Corneal Donor Tissue Lesions by Anterior Segment Optical Coherence Tomography Compared With Eye Bank Technician Slit-Lamp Examination
      Purpose: To compare anterior segment spectral-domain optical coherence tomography (OCT) with eye bank technician slit-lamp examination (SLE) in characterizing lesions in donor corneas. Methods: Twenty-nine donor corneas identified by eye bank technicians to have opacities or lesions potentially representing pathologic findings affecting the stroma were evaluated through the use of technician SLE, SLE photography, and OCT. Technicians were tasked with describing the lesion, estimating the lesion depth, and photographing their ...

    8. Imaging infant retinal vasculature with optical coherence tomography angiography

      Imaging infant retinal vasculature with optical coherence tomography angiography
      Study of infant retinal vascular development has been limited to histopathological reports. We report herein depth-resolved visualization of full-term infant parafoveal microvasculature and their similarity to that of young children using a portable optical coherence tomography angiography system.

    9. Macular Features on Spectral-Domain Optical Coherence Tomography Imaging Associated With Visual Acuity in Coats' Disease

      Macular Features on Spectral-Domain Optical Coherence Tomography Imaging Associated With Visual Acuity in Coats' Disease
      Purpose : To investigate the association between macular features on spectral-domain optical coherence tomography (SD-OCT) and visual acuity (VA) in Coats' disease. Methods : Thirty-nine eyes (39 patients) with SD-OCT from January 1, 2008 to December 31, 2016 were reviewed for SD-OCT features. Central subfield (CSF) SD-OCT findings were analyzed relative to VA (logarithm of the minimum angle of resolution) at baseline and final visit (when follow-up 6 months) and across visits ...

    10. Method and system for improving aiming during optical coherence tomography on young children by synchronization with retinal bifringence scanning

      Method and system for improving aiming during optical coherence tomography on young children by synchronization with retinal bifringence scanning
      The present invention is directed to a method and system for improved aiming during Optical Coherence Tomography (OCT) on young children and those unable to cooperate with OCT imaging by synchronization with retinal birefringence scanning (RBS). OCT is performed without knowing whether or not the subject is looking at the intended target. The present invention combines OCT retinal imaging, such as, but not limited to, time domain OCT, SDOCT, or ...

      Feature of the Week 06/24/2018: Duke University Researchers Show Exciting Advances in Live OCT Volumes in Immersive Virtual Reality
      Virtual reality (VR) head-mounted displays are an attractive technology for viewing intrasurgical optical coherence tomography (OCT) volumes because they liberate surgeons from microscope oculars. We demonstrate real-time, interactive viewing of OCT volumes in a commercial HTC Vive immersive VR system using previously reported ray casting techniques. Furthermore, we show interactive manipulation and sectioning of volumes using handheld controllers and guidance of mock surgical procedures in porcine eyes exclusively within VR ...
