2. Globotrioasylsphingosine Levels and Optical Coherence Tomography Angiography in Fabry Disease Patients
  
  Explore MDPI Open Access Journals Platform Mar 11 2021 Ophthalmology
  
  Background: To date, there are no studies associating the dried blood spot (DBS) levels of globotrioasylsphingosine (lysoGb3) with quantitative optical coherence tomography angiography (OCTA) parameters in Fabry disease (FD) patients. Here, we aimed to investigate the association between OCTA vessel density (VD), vessel length density (VLD) with DBS lysoGb3. Methods: A retrospective, single center analysis of all consecutive FD patients enrolled at the Department of Ophthalmology of the University Hospital ...

5. Quasi-Static Optical Coherence Elastography to Characterize Human Corneal Biomechanical Properties
  
  Explore IOVS Journal Jun 19 2020 Ophthalmology
  
  Purpose : Quasi-static optical coherence elastography (OCE) is an emerging technology to investigate corneal biomechanical behavior in situations similar to physiological stress conditions. Herein OCE was applied to evaluate previously inaccessible biomechanical characteristics of human corneal tissue and to study the role of Bowman's layer in corneal biomechanics. Methods : Human corneal donor buttons ( n = 23) were obtained and Descemet's membrane and endothelium were removed. In 11 corneas, Bowman's ...

6. Spectral Domain Optical Coherence Tomography in Awake Rabbits Allows Identification of the Visual Streak, a Comparison with Histology
  
  Explore TVST Journal Apr 28 2020 Ophthalmology
  
  Purpose : To evaluate visual streak (VS) identification on spectral-domain optical coherence tomography (SD-OCT) scans in awake rabbits. To report thickness measurements in the VS and adjacent retina on OCT B-scans and histologic sections and to assess inter-method bias, precision and repeatability between OCT and histology. Methods : Vertical SD-OCT B-scan images through the optic nerve head and VS were acquired from 16 awake, ophthalmologically healthy experimental rabbits. Scans were acquired from ...

  Fundoscopy, optical coherence tomography (OCT) and OCT-angiography (OCTA) are established examinations and bear minimal risks. The recognition of retinal microvascular signs will enhance the pathophysiological understanding of the vasculopathy in patients with intracerebral haemorrhage (ICH) and aneurysmatic subarachnoid hemorrhage (aSAH) and might serve as prognostic and diagnostic indicators.

  Objectives To determine if Parkinsons disease (PD) and progressive supranuclear palsy (PSP) differed on retinal measurements using optical coherence tomography (OCT). Patients and methods In a prospective, controlled, cross-sectional cohort study, we recruited patients with PD or PSP for more than three years, as well as control subjects. We measured peripapillary retinal nerve fiber layer (RNFL) thickness and macular volume using spectral-domain OCT. The association between these OCT measures and ...

  Purpose : The purpose of this study is to assess with spectral-domain optical coherence tomography (OCT) the interspecies variation of outer retinal morphology and identification of choriocapillaris in four research animal species. Methods : Spectralis HRA+OCT images acquired from locations dorsal, central, and ventral to the optic disc in healthy, anesthetized animals were evaluated by two independent readers. First, the number of OCT B-scans on which a choriocapillaris layer could clearly ...

  Explore Hindawi Publishing Corporation Jul 1 2019 Ophthalmology
  
  Multimodal imaging techniques were performed in a patient with a newly emerged visual field defect; a missing retinal lesion on fundus examination made the diagnosis challenging but infrared imaging showed a larger area of retinal abnormality temporal to the fovea. Indocyanine green angiography (IA) showed late hypofluorescence and there was mild hyperautofluorescence which is known from acute zonal occult outer retinopathy (AZOOR). Despite normal fluorescein angiography (FA) results, a perfusion ...

  Irreversible disability in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) is largely attributed to neuronal and axonal degeneration, which, along with inflammation, is one of the major pathological hallmarks of these diseases. Optical coherence tomography (OCT) is a non-invasive imaging tool that has been used in MS, NMOSD, and other diseases to quantify damage to the retina, including the ganglion cells and their axons. The fact that these ...
