Visual Processing Speed and Objective Analysis of Ocular Movements in Multiple Sclerosis

Multiple Sclerosis Clinical Trial

Official title:
Visual Processing Speed and Objective Analysis of Supranuclear Ocular Movements Control in Multiple Sclerosis Patients and Its Relationship With OCT and Reading Difficulties

Clinical Trial Summary

This project aims to analyze ocular motility problems, visual processing speed and microperimetry, and their relationship with consolidated retinal structural biomarkers (optical coherence tomography, OCT) in patients with Multiple Sclerosis w/w reading complaints comparing with healthy subjects.

Clinical Trial Description

Anamnesis, ophthalmological medical history including difficulties in reading with appropriate glasses. The following protocol will be applied: - Comprehensive eye examination - Stereopsis - Primary gaze position - Cover test: far and near - Vergence and version eye movements - Presence of nystagmus - Far and near best corrected visual acuity, with updated refraction -.Pupillary light reflex - Biomicroscopy of the anterior pole - Intraocular pressure - Recording of eye movements during two standardized tests: International Reading Speed Texts test (IReST®) and Developmental Eye Movement Test (DEM™) with Tobii™ Pro Nano hardware package eye-tracking system and Tobii™ Pro Lab - full edition software. - Visual processing speed - Microperimetry - Optical coherence tomography - Eye fundus - Patients with a history of clinical optic neuritis will additionally undergo contrast sensitivity tests, the Farnsworth® test (Farnsworth test 28 Hue x 100) and normal monocular perimetry using the standard Swedish Interactive Thresholding Algorithm (SITA-central 24-2) perimeter test. Humphrey® (Humphrey visual field analyser) and other tests at the discretion of the investigator. ;
