      Multicenter reliability of semiautomatic retinal layer segmentation using OCT
      Objective To evaluate the inter-rater reliability of semiautomated segmentation of spectral domain optical coherence tomography (OCT) macular volume scans. Methods Macular OCT volume scans of left eyes from 17 subjects (8 patients with MS and 9 healthy controls) were automatically segmented by Heidelberg Eye Explorer (v1.9.3.0) beta-software (Spectralis Viewing Module v6.0.0.7), followed by manual correction by 5 experienced operators from 5 different academic centers ...

      Optical coherence tomography in neuromyelitis optica spectrum disorders: potential advantages for individualized monitoring of progression and therapy
      Neuromyelitis optica spectrum disorders (NMOSD) are mostly relapsing inflammatory disorders of the central nervous system (CNS). Optic neuritis (ON) is the first NMOSD-related clinical event in 55% of the patients, which causes damage to the optic nerve and leads to visual impairment. Retinal optical coherence tomography (OCT) has emerged as a promising method for diagnosis of NMOSD and potential individual monitoring of disease course and severity. OCT not only detects ...

      Explore TheLancet.com Neurology , Ophthalmology
      Retinal thickness measured with optical coherence tomography and risk of disability worsening in multiple sclerosis: a cohort study
      Background Most patients with multiple sclerosis without previous optic neuritis have thinner retinal layers than healthy controls. We assessed the role of peripapillary retinal nerve fibre layer (pRNFL) thickness and macular volume in eyes with no history of optic neuritis as a biomarker of disability worsening in a cohort of patients with multiple sclerosis who had at least one eye without optic neuritis available. Methods In this multicentre, cohort study ...

      The APOSTEL recommendations for reporting quantitative optical coherence tomography studies
      Objective: To develop consensus recommendations for reporting of quantitative optical coherence tomography (OCT) study results. Methods: A panel of experienced OCT researchers (including 11 neurologists, 2 ophthalmologists, and 2 neuroscientists) discussed requirements for performing and reporting quantitative analyses of retinal morphology and developed a list of initial recommendations based on experience and previous studies. The list of recommendations was subsequently revised during several meetings of the coordinating group. Results: We ...

      Retinal pathology in Susac syndrome detected by spectral-domain optical coherence tomography
      Objective: The aim of this non-interventional study was to characterize retinal layer pathology in Susac syndrome (SuS), a disease with presumably autoimmune-mediated microvessel occlusions in the retina, brain, and inner ear, in comparison to the most important differential diagnosis multiple sclerosis (MS). Methods: Seventeen patients with SuS and 17 age- and sex-matched patients with relapsing-remitting MS (RRMS) and healthy controls (HC) were prospectively investigated by spectral-domain optical coherence tomography (OCT ...

      Retinal pathology in idiopathic moyamoya angiopathy detected by optical coherence tomography
      Objective: To investigate whether patients with moyamoya angiopathy without obvious retinal pathologies such as retinal infarctions or the congenital morning glory anomaly may have subtle subclinical retinal changes. Methods: In this cross-sectional study, spectral domain optical coherence tomography was used to analyze the retinal morphology of 25 patients with idiopathic moyamoya angiopathy and 25 age- and sex-matched healthy controls. We analyzed the retinal vasculature with blue laser autofluorescence, lipofuscin deposits ...

      Temporal retinal nerve fibre layer thinning in cluster headache patients detected by optical coherence tomography
      Background The exact pathophysiology of cluster headache (CH) is still not fully clarified. Various studies confirmed changes in ocular blood flow during CH attacks. Furthermore, vasoconstricting medication influences blood supply to the eye. We investigated the retina of CH patients for structural retinal alterations with optical coherence tomography (OCT), and how these changes correlate to headache characteristics, oxygen use and impaired visual function. Methods Spectral domain OCT of 107 CH ...

      Vessel Labeling in Combined Confocal Scanning Laser Ophthalmoscopy and Optical Coherence Tomography Images: Criteria for Blood Vessel Discrimination
      Introduction The diagnostic potential of optical coherence tomography (OCT) in neurological diseases is intensively discussed. Besides the sectional view of the retina, modern OCT scanners produce a simultaneous top-view confocal scanning laser ophthalmoscopy (cSLO) image including the option to evaluate retinal vessels. A correct discrimination between arteries and veins (labeling) is vital for detecting vascular differences between healthy subjects and patients. Up to now, criteria for labeling (cSLO) images generated ...

      Optical coherence tomography in patients with a history of juvenile multiple sclerosis reveals early retinal damage
      Background and purpose Some 3%10% of patients with multiple sclerosis (MS) experience disease onset before the age of 18 years (early onset MS, EOMS). Optical coherence tomography is a non-invasive method to measure retinal nerve fibre layer thickness (RNFLT) and total macular volume (TMV) and may be useful to differentiate axonal and neuronal damage in the retina of patients with a history of EOMS. Here RNFLT and TMV in ...

      The investigation of acute optic neuritis: a review and proposed protocol
      Optic neuritis is an inflammatory optic neuropathy that affects many patients with multiple sclerosis (MS) at some point during their disease course. Differentiation of acute episodes of MS-associated optic neuritis from other autoimmune and inflammatory optic neuropathies is vital for treatment choice and further patient management, but is not always straightforward. Over the past decade, a number of new imaging, laboratory and electrophysiological techniques have entered the clinical arena. To ...

      Quality control for retinal OCT in multiple sclerosis: validation of the OSCAR-IB criteria
      Background: Retinal optical coherence tomography (OCT) permits quantification of retinal layer atrophy relevant to assessment of neurodegeneration in multiple sclerosis (MS). Measurement artefacts may limit the use of OCT to MS research. Objective: An expert task force convened with the aim to provide guidance on the use of validated quality control (QC) criteria for the use of OCT in MS research and clinical trials. Methods: A prospective multi-centre ( n = 13 ...
