1. Optical coherence tomography angiography indicates subclinical retinal disease in neuromyelitis optica spectrum disorders
  
  Explore SAGE Journals Jul 15 2021 Ophthalmology
  
  Background: Neuromyelitis optica spectrum disorders (NMOSD) are neuroinflammatory diseases of the central nervous system. Patients suffer from recurring relapses and it is unclear whether relapse-independent disease activity occurs and whether this is of clinical relevance. Objective: To detect disease-specific alterations of the retinal vasculature that reflect disease activity during NMOSD. Methods: Cross-sectional analysis of 16 patients with NMOSD, 21 patients with relapsing-remitting multiple sclerosis, and 21 healthy controls using retinal optical coherence tomography (OCT), optical coherence tomography angiography (OCT-A), measurement of glial fibrillary acidic protein (GFAP) serum levels, and assessment of visual acuity. Results: Patients with NMOSD but not multiple ...

2. The APOSTEL 2.0 Recommendations for Reporting Quantitative Optical Coherence Tomography Studies
  
  Explore Neurology May 1 2021 Neurology
  
  Objective: To update the consensus recommendations for reporting of quantitative optical coherence tomography (OCT) study results, thus revising the previously published Advised Protocol for OCT Study Terminology and Elements (APOSTEL) recommendations. Methods: To identify studies reporting quantitative OCT results, we performed a PubMed search for the terms "quantitative" and "optical coherence tomography" from 2015 to 2017. Corresponding authors of the identified publications were invited to provide feedback on the initial APOSTEL recommendations via online surveys following the principle of a modified Delphi method. The results were evaluated and discussed by a panel of experts, and changes to the initial recommendations ...

3. Optical coherence tomography in myelin-oligodendrocyte-glycoprotein antibody-seropositive patients: a longitudinal study
  
  Explore Journal of Neuroinflammation Jul 30 2019 Neurology , Ophthalmology
  
  Background Serum antibodies against myelin-oligodendrocyte-glycoprotein (MOG-IgG) are detectable in a proportion of patients with acute or relapsing neuroinflammation. It is unclear, if neuro-axonal damage occurs only in an attack-dependent manner or also progressively. Therefore, this study aimed to investigate longitudinally intra-retinal layer changes in eyes without new optic neuritis (ON) in MOG-IgG-seropositive patients. Methods We included 38 eyes of 24 patients without ON during follow-up (F/U) [median years (IQR)] 1.9 (1.0–2.2) and 56 eyes of 28 age- and sex-matched healthy controls (HC). The patient group’s eyes included 18 eyes without (Eye ON- ) and 20 ...

4. Optimal intereye difference thresholds by optical coherence tomography in multiple sclerosis: An international study
  
  Explore Wiley Online Library May 18 2019 Neurology , Ophthalmology
  
  Objective To determine the optimal thresholds for intereye differences in retinal nerve fiber and ganglion cell + inner plexiform layer thicknesses for identifying unilateral optic nerve lesions in multiple sclerosis. Current international diagnostic criteria for multiple sclerosis do not include the optic nerve as a lesion site despite frequent involvement. Optical coherence tomography detects retinal thinning associated with optic nerve lesions. Methods In this multicenter international study at 11 sites, optical coherence tomography was measured for patients and healthy controls as part of the International Multiple Sclerosis Visual System Consortium. High‐ and low‐contrast acuity were also collected in a subset ...

6. Optical coherence tomography angiography indicates associations of the retinal vascular network and disease activity in multiple sclerosis
  
  Explore SAGE Journals Jan 9 2018 Neurology , Ophthalmology
  
  Background: Patients with multiple sclerosis (MS) and clinically isolated syndrome (CIS) may show alterations of retinal layer architecture as measured by optical coherence tomography. Little is known about changes in the retinal vascular network during MS. Objective: To characterize retinal vessel structures in patients with MS and CIS and to test for associations with MS disease activity. Method: In all, 42 patients with MS or CIS and 50 healthy controls underwent retinal optical coherence tomography angiography (OCT-A) with analysis of the superficial and deep vascular plexuses and the choriocapillaries. We tested OCT-A parameters for associations with retinal layer volumes, history ...

7. Optical coherence tomography indicates disease activity prior to clinical onset of central nervous system demyelination
  
  Explore Multiple Sclerosis Sep 11 2015 Neurology , Ophthalmology
  
  Background: Establishing biomarkers for predicting disease activity in demyelinating disease of the central nervous system is crucial for designing appropriate disease modifiying treatment strategies. Objective: To investigate retinal findings and disease activity in patients with radiologically isolated and clinically isolated syndromes. Methods: We performed retinal optical coherence tomography and cerebral magnetic resonance imaging in healthy control individuals ( n =19), in individuals with non-specific white matter lesions ( n =18), and in patients with clinically isolated syndromes ( n =18) and radiologically isolated syndromes ( n =20). Results: Reduced volume of retinal nerve fibre layer and increased volume of inner nuclear layer at baseline ...
