1. Quality control for retinal OCT in multiple sclerosis: validation of the OSCAR-IB criteria
  
  Explore Multiple Sclerosis Jun 22 2014 Neurology , Ophthalmology
  
  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) study. Peripapillary ring scan QC rating of an OCT training set ( n = 50) was followed by a test set ( n = 50). Inter-rater agreement was calculated using kappa statistics. Results were ...

  26 patients were recruited following acute unilateral damage to the postgeniculate visual pathway (onset 12–50 years prior to testing) together with age and sex matched controls. Peripapillary retinal nerve fibre layer (RNFL) thickness was measured with optical coherence tomography on a single occasion. (2) 7 of the 26 patients and a further 4 patients with incomplete hemianopia were recruited within 5 months of the injury (range 5–177 days). In this group the RNFL thickness was measured serially for at least 43 days (range 43–876 days) to study the rate of change. Results (1) There is a negative ...

  Abstract Thinning of the retinal nerve fiber layer (RNFL) of clinically unaffected eyes is seen in patients with multiple sclerosis (MS). It is uncertain when this thinning occurs, and whether ongoing RNFL loss can be measured over time with optical coherence tomography (OCT). Using time-domain OCT, we studied 34 patients with progressive MS (16 primary progressive MS, 18 secondary progressive; 14 male; 20 female; mean age at study entry 51 years; median EDSS 6; mean disease duration at study entry 12 years) on two occasions with a median interval of 575 (range 411–895) days apart. Eighteen healthy controls (10 ...

4. Assessing structure and function of the afferent visual pathway in multiple sclerosis and associated optic neuritis
  
  Explore SpringerLink Home Mar 20 2009 Neurology , Ophthalmology
  
  Abstract The afferent visual pathway is commonly affected in MS. Assessment of the afferent visual pathway using clinical, imaging and electrophysiological methods not only provides insights into the pathophysiology of MS, but also provides a method of investigating potential therapeutic measures in MS. This review summarises the various assessment methods, in particular imaging techniques of the visual pathway. Retinal nerve fibre layer (RNFL) thickness is usually reduced following an episode of optic neuritis. Techniques such as optical coherence tomography, scanning laser polarimetry, and confocal scanning laser ophthalmoscopy are used to quantify RNFL thickness. MRI of the optic nerve is not ...

Curr Opin Neurol. 2008 Feb;21(1):16-21 Authors: Plant GT PURPOSE OF REVIEW: To discuss recent neuro-ophthalmic advances relevant to the management of optic neuritis and multiple sclerosis. RECENT FINDINGS: Major advances have occurred in the fields of autoimmunity in optic neuritis, and in imaging the retinal nerve fibre layer in both optic neuritis and multiple sclerosis. SUMMARY: A proportion of cases of optic neuritis occur in patients who do not develop multiple sclerosis; the optic neuritis may be monophasic illness or recurrent. In many recurrent cases who also have myelitis (neuromyelitis ...
