Visual (Path)Ways in Multiple Sclerosis - Part II
A study testing Measurement of retinal vascular density and visual cognition in people with Multiple Sclerosis, Optic Neuritis, Demyelinating Disease, run by University Hospital, Lille at 1 site in France.
Trial summary
Multiple sclerosis (MS) is an inflammatory demyelinating and degenerative disease of the central nervous system. The mechanisms of neuro-axonal loss remain incompletely elucidated. An acute demyelinating lesion will produce both immediate and delayed axonal loss. Read more about this study

About this study
Official title: Evaluation of Neuroaxonal Loss Outside of Any Inflammation in Multiple Sclerosis by a Multimodal Study of the Visual Pathways Model
Multiple sclerosis (MS) is an inflammatory demyelinating and degenerative disease of the central nervous system. The mechanisms of neuro-axonal loss remain incompletely elucidated. An acute demyelinating lesion will produce both immediate and delayed axonal loss. Immediate axonal loss is linked to the occurrence of axonal transection. Delayed axonal loss is the cause of axonal degeneration in progressive MS. Visual impairment is common in the disease (vision, oculomotricity, cognition). Through a longitudinal multimodal analysis of visual pathways, we would like to investigate physiopathological mechanisms leading to neurodegenerative process and visual impairment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Measurement of retinal vascular density and visual cognitionOther
During the same visit, we will perform OCT-angiography (10 minutes) and evaluate visual cognition with an eye-tracker (20 minutes)

| Not applicable. No treatment will be compared. | Other | During the same visit, we will perform OCT-angiography (10 minutes) and evaluate visual cognition with an eye-tracker (20 minutes) Receives: Other: Measurement of retinal vascular density and visual cognition |
What is being measured
The primary outcome is the main question the study is designed to answer.
Quantifying progressive retinal axonal loss in the absence of inflammation
To quantify progressive retinal neuroaxonal loss in a context of no active inflammation : Difference in retinal atrophy (GCIPL volume in [VWIMS I] - GCIPL volume in VWIMS II)
Measured: First time point already done (VWIMS study) Second time point during VWIMS -II study. Interval between time points will be around 7-8 years
