2. Quality of Threshold Algorithm in Age-related Macular Degeneration: Stratus versus Cirrus OCT

   iovs.org (Nov 26 2008) Ophthalmology Explore Article

   Introduction: Automatically generated measurements of the retinal volume or the central retinal thickness are based on correctly set threshold lines on the retinal surface and the retinal pigment epithelium. The aim of this study was to compare the accuracy of threshold algorithm lines of Stratus optical coherence tomography (OCT) with those of Cirrus OCT. Methods: A consecutive series of patients aged at least 50 years with exudative age-related macular degeneration ... (Read Full Article)

3. Analysis of the Origin of Atypical Scanning Laser Polarimetry Patterns by Polarization-Sensitive Optical Coherence Tomography

   iovs.org (Nov 25 2008) Ophthalmology Explore Article

   This study uses polarization-sensitive optical coherence tomography to identify the reasons for atypical scanning laser polarimetry patterns; the predominant source of these artifacts is increased penetration of the probing light into the strongly birefringent sclera. (Read Full Article)

5. Three-dimensional angiographic imaging of leakage in branch retinal vein occlusion

   www3.interscience.wiley.com (Oct 17 2008) Ophthalmology Explore Article

   Purpose: Optical coherence tomography (OCT) is used to image branch retinal vein occlusion (BRVO) but lacks information about leakage dynamics and perfusion status. Topographical angiography (TAG) is capable of providing this information and has been described previously in age-related macular degeneration. This study evaluates TAG in BRVO.Methods: We included 56 eyes of 40 consecutive patients with BRVO and a reduction in central vision. Two groups were established based on whether ...

   Erich Götzinger, Michael Pircher, Wolfgang Geitzenauer, Christian Ahlers, Bernhard Baumann, Stephan Michels, Ursula Schmidt-Erfurth, Christoph K. HitzenbergerWe present a new method for identifying and segmenting the retinal pigment epithelium (RPE) in polarization sensitive optical coherence tomography (PS-OCT) images of the human retina. Contrary to previous, intensity based segmentation algorithms, our method uses an intrinsic tissue property of ... [Opt. Express 16, 16410-16422 (2008)] (Read Full Article)

7. The Validity of Retinal Blood Flow Measurements During Hyperoxia in Humans Using Fourier Domain Color Doppler Optical Coherence Tomography (CDOCT)

   Home - ClinicalTrials.gov (Sep 9 2008) Ophthalmology Explore Article

   Noninvasive monitoring of blood flow in retinal circulation may elucidate the progression and treatment of ocular disorders, including diabetic retinopathy, age-related macular degeneration and glaucoma. Laser Doppler velocimetry (LDV), a noninvasive optical method combined with vessel size determination has been used extensively as a valuable research tool to examine blood flow dynamics in the human retina. However, no information on the velocity profile within the vessel is available. Ophthalmic color ... (Read Full Article)

8. Update: histopathology-based definition of gastroesophageal reflux disease and Barrett's esophagus

   SpringerLink Home (Aug 28 2008) Endoscopy Explore Article

   Summary BACKGROUND: Gastroesophageal reflux disease (GERD) is associated with columnar lined esophagus (CLE) and Barrett's esophagus (BE), which may progress towards esophageal adenocarcinoma. Currently a mixture of symptoms, endoscopic and histopathologic criteria and results obtained from esophageal function tests define GERD. We searched for a histopathology-based definition of GERD. METHODS: Review on GERD-histopathology. RESULTS: Multilevel biopsies and the novel Paull-Chandrasoma histopathology-classification of CLE define those with reflux and risk for ...
