  Machine learning approaches in diagnosis and prognosis of multiple sclerosis (MS) were analysed using retinal nerve fiber layer (RNFL) thickness, measured by optical coherence tomography (OCT). A cross-sectional study (72 MS patients and 30 healthy controls) was used for diagnosis. These 72 MS patients were involved in a 10-year longitudinal follow-up study for prognostic purposes. Structural measurements of RNFL thickness were performed using different Spectralis OCT protocols: fast macular thickness ...

8. Machine learning in diagnosis and disability prediction of multiple sclerosis using optical coherence tomography
  
  Explore ScienceDirect May 1 2021 Neurology , Ophthalmology
  
  Background Multiple sclerosis (MS) is a neurodegenerative disease that affects the central nervous system, especially the brain, spinal cord, and optic nerve. Diagnosis of this disease is a very complex process and generally requires a lot of time. In addition, treatments are applied without any information on the disability course in each MS patient. For these two reasons, the objective of this study was to improve the MS diagnosis and ...

  Explore ScienceDirect Dec 8 2020 Neurology , Ophthalmology
  
  Background The consequences of inflammation, demyelination, axonal degeneration and neuronal loss in the central nervous system, typical of the development of multiple sclerosis (MS), are manifested in thinning of the retina and optic nerve. The purpose of this work is to diagnose early-stage MS patients based on analysis of retinal layer thickness obtained by swept-source optical coherence tomography (SS-OCT). Method OCT (Triton SS-OCT device -Topcon, Tokyo, Japan-) recordings were obtained ...

12. Use of the new MultiColour SPECTRALIS® software for identifying retinal nerve fibre layer defects
  
  Explore ScienceDirect Sep 5 2020 Ophthalmology
  
  The classical fibre photography traditionally used to identify defects in the retinal nerve fibre layer (RNFL), has been partially discontinued due to poor availability. The new MultiColour module of SPECTRALIS Optical Coherence Tomography (OCT), using three different laser wavelengths simultaneously, can provide images that identify the structures of the retina in different colours according to their depth. A small concordance study was conducted to determine the usefulness of the new ...
