    2. Multicenter reliability of semiautomatic retinal layer segmentation using OCT

      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 ...

    3. Retinal thickness measured with optical coherence tomography and risk of disability worsening in multiple sclerosis: a cohort study

      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 ...

    4. The APOSTEL recommendations for reporting quantitative optical coherence tomography studies

      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 ...

    5. Retinal pathology in Susac syndrome detected by spectral-domain optical coherence tomography

      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 ...

    6. Temporal retinal nerve fibre layer thinning in cluster headache patients detected by optical coherence tomography

      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 ...

    7. OCT measurements of optic nerve head changes in idiopathic intracranial hypertension

      OCT measurements of optic nerve head changes in idiopathic intracranial hypertension
      Objective Severity of papilledema and vision loss constitute a basis for therapeutic intervention in idiopathic intracranial hypertension (IIH), but both are often subjective and insensitive in guiding clinical management. The aim of this study was to identify reliable and sensitive measurements of optic nerve head (ONH) and macula, to provide objective guidance for prognostic evaluation and treatment in IIH. We analyzed potential of spectral domain optical coherence tomography (SD-OCT), to ...

    9. Optical coherence tomography in patients with a history of juvenile multiple sclerosis reveals early retinal damage

      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 ...

    11. Optical Coherence Tomography Reveals Distinct Patterns of Retinal Damage in Neuromyelitis Optica and Multiple Sclerosis

      Optical Coherence Tomography Reveals Distinct Patterns of Retinal Damage in Neuromyelitis Optica and Multiple Sclerosis
      Background Neuromyelitis optica (NMO) and relapsing-remitting multiple sclerosis (RRMS) are difficult to differentiate solely on clinical grounds. Optical coherence tomography (OCT) studies investigating retinal changes in both diseases focused primarily on the retinal nerve fiber layer (RNFL) while rare data are available on deeper intra-retinal layers. Objective To detect different patterns of intra-retinal layer alterations in patients with NMO spectrum disorders (NMOSD) and RRMS with focus on the influence of ...

    12. Optical coherence tomography does not support optic nerve involvement in amyotrophic lateral sclerosis

      Optical coherence tomography does not support optic nerve involvement in amyotrophic lateral sclerosis
      Background and purpose In recent years a possible non-motor involvement of the nervous system in amyotrophic lateral sclerosis (ALS) has come into the focus of research and has been investigated by numerous techniques. Optical coherence tomography (OCT) with its potential to reveal neuroaxonal retinal damage may be an appropriate tool to investigate whether the anterior visual pathway is involved. Our aim was to determine whether OCT-based measures of retinal nerve ...

    13. Optic neuritis interferes with optical coherence tomography and magnetic resonance imaging correlations

      Optic neuritis interferes with optical coherence tomography and magnetic resonance imaging correlations
      Background: Retinal nerve fibre layer (RNFL) thinning is associated with brain atrophy in multiple sclerosis (MS). An influence of optic neuritis is well documented but sparsely investigated. Recently, the retinal ganglion cell layer (GCL) has been shown to provide superior information regarding visual function and retinal neurodegeneration as compared with RNFL. Objective: To investigate the association of white and grey matter brain volume with peripapillary RNFL and macular GCL in ...

      Background. Optical coherence tomography (OCT) has facilitated characterisation of retinal alterations in MS patients. Only scarce and in part conflicting data exists on different MS subtypes. Objective. To analyse patterns of retinal changes in different subtypes of MS with latest spectral-domain technology. Methods. In a three-centre cross-sectional study 414 MS patients and 94 healthy controls underwent spectral-domain OCT examination. Results. Eyes of MS patients without a previous optic neuritis showed ...
