    2. Optical Coherence Tomography Angiography of RPGR-Associated Retinitis Pigmentosa Suggests Foveal Avascular Zone is a Biomarker for Vision Loss

      Optical Coherence Tomography Angiography of RPGR-Associated Retinitis Pigmentosa Suggests Foveal Avascular Zone is a Biomarker for Vision Loss
      RPGR -associated retinitis pigmentosa (RP) is a progressive disease with retina degeneration. Optical coherence tomography angiography (OCTA) is an imaging technique that provides novel insights. The authors report two affected male siblings who underwent OCTA imaging. The area of the foveal avascular zone (FAZ) was measured. Although the younger sibling exhibited more advanced clinical disease, his visual acuity was superior to his older sibling. OCTA imaging revealed a better preserved ...

    3. Optical Coherence Tomography Angiography Findings in Chronic Central Serous Chorioretinopathy After Photodynamic Therapy

      Optical Coherence Tomography Angiography Findings in Chronic Central Serous Chorioretinopathy After Photodynamic Therapy
      BACKGROUND AND OBJECTIVES: To report the acute and long-term choroidal findings in patients with chronic central serous chorioretinopathy (CCSC) undergoing half-fluence photodynamic therapy (PDT). PATIENTS AND METHODS: This is a prospective, consecutive, interventional, noncomparative case series at a tertiary referral vitreoretinal practice. Twenty-one eyes from 21 patients are included. RESULTS: Among 21 eyes, all had improved vision following PDT during a mean of 5.2 months 4.8 months of ...

    4. Comparison of Optical Coherence Tomography With Fundus Photographs, Fluorescein Angiography, and Histopathologic Analysis in Assessing Coats Disease

      Comparison of Optical Coherence Tomography With Fundus Photographs, Fluorescein Angiography, and Histopathologic Analysis in Assessing Coats Disease
      Importance Coats disease is a rare pediatric vitreoretinopathy that can cause devastating visual and anatomic outcomes. Objective To compare optical coherence tomography (OCT) with fundus photographs, fluorescein angiography (FA), and histopathologic findings in Coats disease. Design, Setting, and Participants This retrospective cohort study was conducted in a single tertiary institution (Duke Eye Center) and identified 28 children with Coats disease through a review of medical records from December 2002 to ...

    5. Gold Nanoprisms as Optical Coherence Tomography Contrast Agents in the Second Near-Infrared Window for Enhanced Angiography in Live Animals

      Gold Nanoprisms as Optical Coherence Tomography Contrast Agents in the Second Near-Infrared Window for Enhanced Angiography in Live Animals
      Optical coherence tomography angiography (OCTA) is an important tool for investigating vascular networks and microcirculation in living tissue. Traditional OCTA detects blood vessels via intravascular dynamic scattering signals derived from the movements of red blood cells (RBCs). However, the low hematocrit and long latency between RBCs in capillaries make these OCTA signals discontinuous, leading to incomplete mapping of the vascular networks. OCTA imaging of microvascular circulation is particularly challenging in ...

    7. 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 ...

    8. Quantitative progression of retinitis pigmentosa by optical coherence tomography angiography

      Quantitative progression of retinitis pigmentosa by optical coherence tomography angiography
      Optical coherence tomography angiography (OCT-A) is a non-invasive alternative to fluorescein angiography that allows for the study of the retinal and choroidal vasculatures. In this retrospective cohort study of 28 patients with retinitis pigmentosa (RP), we used OCT-A to quantify changes in perfusion density, foveal avascular zone (FAZ) area, and choriocapillaris blood flow over time and correlated these variables with ellipsoid zone (EZ) line width and best-corrected visual acuity (BCVA ...

    9. Intraoperative Imaging Modalities and the Potential Role of Speckle Modulating Optical Coherence Tomography

      Intraoperative Imaging Modalities and the Potential Role of Speckle Modulating Optical Coherence Tomography
      Maximizing extent of resection has been correlated with improved outcomes in a variety of pediatric and adult brain tumors. 1-11 While gross total resections are often achieved without the use of intraoperative adjuncts, difficulty in distinguishing tumor from normal brain can at times prevent the complete resection of brain tumors. Intraoperative imaging tools have increasingly been embraced with the goal of improving rates of gross total resection. In this review ...

    10. Automatically Determining the Confocal Parameters from OCT B-Scans for Quantification of the Attenuation Coefficients

      Automatically Determining the Confocal Parameters from OCT B-Scans for Quantification of the Attenuation Coefficients
      The attenuation coefficient is a relevant biomarker for many diagnostic medical applications. Recently, the Depth- Resolved Confocal (DRC) technique was developed to automatically estimate the attenuation coefficients from Optical Coherence Tomography (OCT) data with pixel-level resolution. However, DRC requires that the confocal function parameters (i.e., focal plane location and apparent Rayleigh range) be known a priori. In this paper we present the autoConfocal algorithm: a simple, automatic method for ...
