Exploration of Microcirculatory Alteration and Endothelial Dysfunction by Adaptive Optics in Multiple Sclerosis (MS-EYE)

Versailles Hospital

Status: Unknown

Conditions: Sclerosis, Multiple

Treatments: Other: Ocular Fundus on voluntary person; Other: Ocular fundus on patient with Multiple Sclerosis

Study type: Interventional

Funder types: Other

Identifiers

NCT03508089

P15/18_ MS-EYE

Details and patient eligibility

About

It's a pilot, interventional prospective monocentric study. It aims to compare the wall / lumen ratio (WLR) of retinal arterioles (common marker of microangiopathies) between patients with multiple sclerosis and controls using the technique of adaptive optics.

Enrollment: 60 estimated patients

Sex: All

Ages: 18 to 50 years old

Volunteers: Accepts Healthy Volunteers
