    2. Optical Coherence Tomography and Wide-Field Fluorescein Angiography in Retinopathy of Prematurity (Book Chapter)

      Optical Coherence Tomography and Wide-Field Fluorescein Angiography in Retinopathy of Prematurity (Book Chapter)
      The advent and adaptation of many imaging modalities promise to revolutionize our understanding of retinopathy of prematurity (ROP) by improving the detection, diagnosis, and monitoring of response to treatment of this disease. Diagnosis and classification of ROP traditionally relies on an eye exam by an ophthalmologist expert in this area who characterizes extent and character of retinal vascularization via indirect ophthalmoscopy. Many tools now exist that allow for data acquisition ...

    3. The application of optical coherence tomography in neurologic diseases

      The application of optical coherence tomography in neurologic diseases
      Optical coherence tomography (OCT) has become an increasingly popular tool in various disciplines of medicine, particularly ophthalmology and neurology. It is an imaging technology that has revolutionized the practice of ophthalmology by providing anatomic detail of pathologic changes in the retina and optic nerve. OCT is routinely used as an ancillary test that can aid in the diagnosis and monitoring of neuro-ophthalmic diseases such as papilledema, optic neuritis, and neuroretinitis ...

    4. Retinal Imaging of Infants on Spectral Domain Optical Coherence Tomography

      Retinal Imaging of Infants on Spectral Domain Optical Coherence Tomography
      Spectral domain coherence tomography (SD OCT) has become an important tool in the management of pediatric retinal diseases. It is a noncontact imaging device that provides detailed assessment of the microanatomy and pathology of the infant retina with a short acquisition time allowing office examination without the requirement of anesthesia. Our understanding of the development and maturation of the infant fovea has been enhanced by SD OCT allowing an in ...

    6. Macular Findings in Healthy Full-term Hispanic Newborns Observed by Hand-held Spectral-Domain Optical Coherence Tomography

      Macular Findings in Healthy Full-term Hispanic Newborns Observed by Hand-held Spectral-Domain Optical Coherence Tomography
      BACKGROUND AND OBJECTIVE: To enhance understanding of ethnically diverse normal newborn retinal morphology, the authors report spectral-domain optical coherence tomography (SD-OCT) macular findings in healthy Hispanic newborns. PATIENTS AND METHODS: In this IRB-approved prospective, observational case series, 20 full-term Hispanic newborns had dilated retinal examinations and imaging by hand-held SD-OCT without sedation at the Duke Birthing Center. RESULTS: Of 20 newborns imaged (35% male; median gestational age: 39 weeks; range ...

    7. Choroid Development and Feasibility of Choroidal Imaging in the Preterm and Term Infants Utilizing SDOCT

      Choroid Development and Feasibility of Choroidal Imaging in the Preterm and Term Infants Utilizing SDOCT
      Purpose: To determine whether choroidal imaging is feasible in preterm and term infants using an 840-nm portable spectral domain optical coherence tomography (SDOCT) system without the use of enhanced- depth imaging techniques and to assess choroidal development by comparing choroidal thickness of preterm infants, term infants, and adults. Methods: SDOCT images were obtained from 86 preterm infants, 59 term infants and 9 adults using a portable SDOCT (Bioptigen, Inc., NC ...

    8. Photoreceptor and Choroid Development Assessed with Handheld SD-OCT

      Photoreceptor and Choroid Development Assessed with Handheld SD-OCT
      Objective: Optical coherence tomography (OCT) allows examination of the human retina. While conventional OCT devices are limited mainly to adults, the availability of a handheld system has expanded the use of this technique to pediatric populations, with the primary clinical applications being shaken baby syndrome and retinopathy of prematurity. We sought to apply OCT imaging to neonatal population to assess retinal development. Methods: Subjects imaged at the Duke Neonatal Intensive ...

    9. Visualization of Real-Time Intraoperative Maneuvers with a Microscope-Mounted Spectral Domain Optical Coherence Tomography System

      Visualization of Real-Time Intraoperative Maneuvers with a Microscope-Mounted Spectral Domain Optical Coherence Tomography System
      The advent of optical coherence tomography (OCT) has revolutionized our diagnostic and therapeutic capabilities in ophthalmology and vitroretinal disease. In the clinic setting, OCT has touch nearly every aspect of vitreoretinal disease. More recently, OCT has been introduced into the operating room theater. Intraoperative OCT (iOCT) has been uses successfully...

    10. Image inversion spectral-domain optical coherence tomography optimizes choroidal thickness and detail through improved contrast

      Image inversion spectral-domain optical coherence tomography optimizes choroidal thickness and detail through improved contrast
      Purpose: To determine whether there were significant differences in choroidal thickness, contrast, outer choroidal vessel (OCV) and choroidal-scleral junction (CSJ) visualization in inverted versus upright spectral-domain optical coherence tomography (SD-OCT). Methods: Images were captured on Bioptigen SD-OCT (Bioptigen Inc., Research Triangle Park, North Carolina), Zeiss Cirrus HD-OCT (Carl Zeiss Meditec Inc, Dublin, CA), and Heidelberg Spectralis (Heidelberg Engineering, Heidelberg, Germany) in 42 eyes of 21 healthy subjects. Average choroidal thickness ...
