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

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.
