    5. Insights From the Retina on Cerebral Microvascular Dysfunction in Haemorrhagic Stroke. A Prospective Observational Study

      Insights From the Retina on Cerebral Microvascular Dysfunction in Haemorrhagic Stroke. A Prospective Observational Study
      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.

    6. Optical coherence tomography of patients with Parkinson’s disease and progressive supranuclear palsy

      Optical coherence tomography of patients with Parkinson’s disease and progressive supranuclear palsy
      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 ...

    7. Optical coherence tomography en face analysis of the posterior vitreous reveal topographic relationships between premacular bursa, prevascular fissures and cisterns

      Optical coherence tomography en face analysis of the posterior vitreous reveal topographic relationships between premacular bursa, prevascular fissures and cisterns
      Purpose To characterize the topographic relationships among vitreous structures including the premacular bursa, prevascular vitreous fissures, cisterns and lacunae in healthy subjects using en face and cross-sectional swept-source optical coherence tomography (SS-OCT). Design Prospective comparative study. Subjects Sixty eyes of 60 healthy subjects (age range = 4 35 years). Eyes of individuals younger than 20 years (n= 29) were compared with eyes of individuals aged 20 years or older (n=31 ...

    8. Interspecies Variation of Outer Retina and Choriocapillaris Imaged With Optical Coherence Tomography

      Interspecies Variation of Outer Retina and Choriocapillaris Imaged With Optical Coherence Tomography
      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 ...

    9. Optical Coherence Tomography Angiography (OCT-A) in a Patient with Occult Retinal Dysfunction

      Optical Coherence Tomography Angiography (OCT-A) in a Patient with Occult Retinal Dysfunction
      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 ...

    10. Changes in Coronary Plaque Composition in Patients With Acute Myocardial Infarction Treated With High-Intensity Statin Therapy (IBIS-4): A Serial Optical Coherence Tomography Study

      Changes in Coronary Plaque Composition in Patients With Acute Myocardial Infarction Treated With High-Intensity Statin Therapy (IBIS-4): A Serial Optical Coherence Tomography Study
      Objectives This study assessed changes in optical coherence tomography (OCT)-defined plaque composition in patients with ST-elevation myocardial infarction (STEMI) receiving high-intensity statin treatment. Background OCT is a high-resolution modality capable of measuring plaque characteristics including fibrous cap thickness (FCT) and macrophage infiltration. There is limited in vivo evidence regarding the effects of statins on OCT-defined coronary atheroma composition and no evidence in the context of STEMI. Methods In the ...

    13. Optical Coherence Tomography and Magnetic Resonance Imaging in Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorder

      Optical Coherence Tomography and Magnetic Resonance Imaging in Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorder
      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 ...
