      A comparison of optic disc area measured by confocal scanning laser tomography versus Bruch’s membrane opening area measured using optical coherence tomography

      Background: Precise optic disc size measurements based on anatomically exact disc margins are fundamental for a correct assessment of glaucoma suspects. Computerized imaging techniques, such as confocal-scanning-laser-tomography (CSLT), which applies operator defined boundaries and optical-coherence-tomography (OCT), which incorporates an alternative detectable landmark (Bruch's-membrane-opening (BMO)), have simplified the planimetry of the optic disc and BMO-area, respectively. This study's objectives are to compare both modalities for area and to define a threshold for macro-BMO using BMO-OCT. Methods: Retrospectively, patients that simultaneously received CSLT and BMO-OCT scans were included. Their images were correlated and agreement was determined using Bland-Altman-analysis. The diagnostic ...

    2. Comparison of Current Optical Coherence Tomography Angiography Methods in Imaging Retinal Hemangioblastomas

      Comparison of Current Optical Coherence Tomography Angiography Methods in Imaging Retinal Hemangioblastomas

      Purpose : To compare spectral-domain (SD) and swept-source (SS) optical coherence tomography angiography (OCTA) for imaging retinal capillary hemangioblastomas (RCHs) in von Hippel-Lindau disease (VHLD). Methods : Prospective single-center cross-sectional study. Tumor size (TS) of perfused RCHs was assessed clinically in relation to the optic disc size. For both technologies, SD-OCTA and SS-OCTA, corresponding images with a scan size of 3 × 3 mm 2 and 6 × 6 mm 2 , respectively, were overlaid according to the set of marker positions to determine the TS. Results : From 200 patients with VHLD, 48 patients showed 84 RCHs. SD-OCTA images of 39 RCHs (46.4%) and ...

    3. Value of Optical Coherence Tomography Angiography Imaging in Diagnosis and Treatment of Hemangioblastomas in von Hippel-Lindau Disease

      Value of Optical Coherence Tomography Angiography Imaging in Diagnosis and Treatment of Hemangioblastomas in von Hippel-Lindau Disease

      BACKGROUND AND OBJECTIVE: The introduction of optical coherence tomography angiography (OCTA) provides new insights into the retinal vasculature. The aim of this study was to explore the value of OCTA in imaging retinal hemangioblastomas and monitoring laser treatment in patients with von Hippel-Lindau (VHL) disease. PATIENTS AND METHODS: Ten eyes of 10 patients with VHL disease were included in this retrospective case series. All patients underwent complete ophthalmological work-up including OCTA for retinal and optic nerve head hemangioblastoma. RESULTS: Two patients showed retinal scars and no recurrence of hemangioblastoma in OCTA. Three patients revealed recurrent hemangioblastomas. Two patients demonstrated a ...
