    2. Filigree vascular pattern in Combined Hamartoma of Retina and Retinal Pigment Epithelium on Optical Coherence Tomography Angiography

      Filigree vascular pattern in Combined Hamartoma of Retina and Retinal Pigment Epithelium on Optical Coherence Tomography Angiography
      Objective To evaluate the vascular structure within combined hamartoma of retina and retinal pigment epithelium (CHRRPE) lesions using optical coherence tomography angiography (OCT-A). Design: Multicentre retrospective observational analysis Subjects: 20 eyes of patients diagnosed with CHRRPE Methods Retrospective analysis of color fundus photographs, optical coherence tomography (OCT) and OCT-A of 20 eyes with CHRRPE. Morphological characteristics of CHRRPE and the OCT features were correlated with the density of the filigree ...

    3. Peripapillary versus macular combined hamartoma of the retina and retinal pigment epithelium: Imaging characteristics

      Peripapillary versus macular combined hamartoma of the retina and retinal pigment epithelium: Imaging characteristics
      Purpose To compare clinical, optical coherence tomography (OCT), and fundus autofluorescence (FAF) characteristics of peripapillary versus (vs.) macular variants of combined hamartoma of the retina and retinal pigment epithelium (combined hamartoma). Design Retrospective observational, comparative case series Methods:Setting Multicentre collaborative study Study Population 50 eyes with a clinical diagnosis of combined hamartoma Observational Analysis A comparative analysis of color fundus photographs (CFPs), OCT and FAF was performed for peripapillary ...

    4. Different phenotypes of the appearance of the outer plexiform layer on optical coherence tomography

      Different phenotypes of the appearance of the outer plexiform layer on optical coherence tomography
      Purpose To present a selected case series of different phenotypes of the normal outer plexiform layer (OPL) visualized by optical coherence tomography (OCT). Methods Five cases were selected to represent the spectrum of appearances of the OPL in this case series. Categorical descriptions of each manifestation were then developed. Additional SD-OCT scans were obtained from a normal volunteer to further support the hypothesis. Results The inner one-third of the OPL ...

    5. Assessment of Frame-Averaging Algorithms in OCT Image Analysis

      Assessment of Frame-Averaging Algorithms in OCT Image Analysis
      BACKGROUND AND OBJECTIVE: To evaluate frame registration and averaging algorithms for optical coherence tomography. PATIENTS AND METHODS: Twenty normal and 20 glaucomatous eyes were imaged. Objective differences were measured by comparing noise variance, spread of edge, and contrast-to-noise ratio. Subjective image quality was also evaluated. RESULTS: Two frame-averaging algorithms (FA400 and FA407) had better noise variance and contrast-to-noise ratio but worse spread of edge than did single frames ( P .01 ...

    6. Evaluation of the Axial Location of Cystoid Spaces in Retinal Vein Occlusion Using Optical Coherence Tomography

      Evaluation of the Axial Location of Cystoid Spaces in Retinal Vein Occlusion Using Optical Coherence Tomography
      Purpose: To analyze the axial distribution of intraretinal cystoid changes in patients with retinal vein occlusion (RVO), incorporating a new hypothesis about the optical coherence tomographic boundary between the outer nuclear layer and the outer plexiform layer. Methods: Data were collected from patients with RVO who underwent spectral domain coherence tomography imaging. For each image set, certified graders evaluated each retinal layer for cystoid macular edema, defined as hyporeflective intraretinal ...

    7. Juxtapapillary Pigment Epithelium Detachment Observed in Asymptomatic Participants using Optical Coherence Tomograph

      Juxtapapillary Pigment Epithelium Detachment Observed in Asymptomatic Participants using Optical Coherence Tomograph
      Purpose. To use three-dimensional optical coherence tomography (3D-OCT) to assess the prevalence of juxtapapillary retinal pigment epithelial detachments (jPED) in an asymptomatic population. Methods. Asymptomatic participants (i.e. family members of patients) were prospectively recruited over a six-month period. Each subject completed a questionnaire prior to the acquisition of two undilated 45 fundus images and two undilated raster 3D-OCT scans (512x128) covering the macula and optic nerve from each eye ...

    8. Correlation Between Optical Coherence Tomography–Derived Assessments of Lower Tear Meniscus Parameters and Clinical Features of Dry Eye Disease

      Correlation Between Optical Coherence Tomography–Derived Assessments of Lower Tear Meniscus Parameters and Clinical Features of Dry Eye Disease
      Purpose: To measure the correlation between subjective symptom score, conventional clinical tests, and Fourier-domain optical coherence tomography (FD-OCT) of lower tear meniscus parameters in patients with dry eye disease.Methods: Eighteen patients with dry eye disease requiring medical therapy and/or punctal occlusion were recruited for this prospective, nonrandomized, observational case series. Severity of symptoms of dry eye disease was assessed using the Indiana University Dry Eye Questionnaire 2002. Clinical ...
