    2. Detecting Retinal Nerve Fibre Layer Segmentation Errors on Spectral Domain-Optical Coherence Tomography with a Deep Learning Algorithm

      Detecting Retinal Nerve Fibre Layer Segmentation Errors on Spectral Domain-Optical Coherence Tomography with a Deep Learning Algorithm
      n this study we developed a deep learning (DL) algorithm that detects errors in retinal never fibre layer (RNFL) segmentation on spectral-domain optical coherence tomography (SDOCT) B-scans using human grades as the reference standard. A dataset of 25,250 SDOCT B-scans reviewed for segmentation errors by human graders was randomly divided into validation plus training (50%) and test (50%) sets. The performance of the DL algorithm was evaluated in the ...

    3. Optical Coherence Tomography normative peripapillary retinal nerve fiber layer and macular data in children ages 0-5 years

      Optical Coherence Tomography normative peripapillary retinal nerve fiber layer and macular data in children ages 0-5 years
      Purpose To determine reference values for the peripapillary retinal nerve fiber layer (pRNFL) and macula in children ages 0-5 years. Design Prospective cross-sectional study Setting Single large academic pediatric ophthalmology practice Study Population Healthy, full-term children ages 0 to 6 years presenting for surgery under general anesthesia were prospectively recruited for participation. Excluded were children with systemic neurologic disease, optic nerve or retinal disease (even if unilateral), or any bilateral ...

    4. First Clinical Application of Low-Cost OCT

      First Clinical Application of Low-Cost OCT
      Purpose : We present the design of a new low-cost optical coherence tomography (OCT) system and compare its retinal imaging capabilities to a standard commercial system through a clinical study. Methods : A spectral-domain OCT system was designed using various cost-reduction techniques to be low-cost, highly portable, and completely stand-alone. Clinical imaging was performed on 120 eyes of 60 patients (60 eyes of normal volunteers and 60 eyes with retinal disease) using ...

    5. Handheld Optical Coherence Tomography Normative Inner Retinal Layer Measurements for Children <5 Years

      Handheld Optical Coherence Tomography Normative Inner Retinal Layer Measurements for Children <5 Years
      Purpose Measurements of the ganglion cell complex (GCC), comprising the retinal nerve fiber (RNFL), ganglion cell, and inner plexiform layers, can be correlated with vision loss caused by optic nerve disease. Handheld optical coherence tomography (HH-OCT) can be used with sedation in children not amenable to traditional imaging. Purpose: to report GCC and RNFL measurements in normal children using HH-OCT. Design Prospective observational study of normal children 5-years of age ...

    6. Ocular anterior chamber blood cell population differentiation using spectroscopic optical coherence tomography

      Ocular anterior chamber blood cell population differentiation using spectroscopic optical coherence tomography
      There is potential clinical significance in identifying cellular responses in the anterior chamber (AC) of the eye, which can indicate hyphema (an accumulation of red blood cells [RBCs]) or aberrant intraocular inflammation (an accumulation of white blood cells [WBCs]). In this work, we developed a spectroscopic OCT analysis method to differentiate between populations of RBCs and subtypes of WBCs, including granulocytes, lymphocytes and monocytes, both in vitro and in ACs ...

    8. Performance of the “Rule of 5” for Detecting Glaucoma Progression Between Visits with Optical Coherence Tomography

      Performance of the “Rule of 5” for Detecting Glaucoma Progression Between Visits with Optical Coherence Tomography
      Purpose To evaluate whether loss of 5 m in global retinal nerve fiber layer (RNFL) thickness on spectral-domain optical coherence tomography (SDOCT) between two consecutive visits is specific for glaucoma progression. Design Prospective cohort. Participants 92 eyes in 49 controls and 300 eyes in 210 glaucoma subjects. Methods Study subjects completed at least five standard automated perimetry and SDOCT examinations at 6-month intervals over at least 2 years. Eyes were ...

    10. Macular Microvascular Findings in Familial Exudative Vitreoretinopathy on Optical Coherence Tomography Angiography

      Macular Microvascular Findings in Familial Exudative Vitreoretinopathy on Optical Coherence Tomography Angiography
      BACKGROUND AND OBJECTIVE: To describe depth-resolved macular microvasculature abnormalities in patients with familial exudative vitreoretinopathy (FEVR) using optical coherence tomography angiography (OCTA). PATIENTS AND METHODS: Twenty-two eyes (11 eyes of six patients with FEVR and 11 control eyes) were imaged with OCTA. Graders qualitatively analyzed the OCTA images of the superficial and deep vascular complexes for abnormal vascular features and compared to fluorescein angiography (FA). RESULTS: Seven of 11 eyes ...

  2. About Duke University

    Duke University

    Duke University is a private research university located in Durham, North Carolina, USA. Duke University Medical CenterFor more than 75 years, our community of scholars and students has been devoted to understanding the causes, prevention and treatment of human disease. Duke University Eye Center is part of the Medical School.  Duke University's Pratt School of Engineering established The Fitzpatrick Center for Photonics and Communications Systems in December 2000 to help turn North Carolina into a "photon forest" where research and development in photonics would create the kind of technological advance and economic growth found in California's Silicon Valley.
