Visual Processing Speed and Objective Analysis of Ocular Movements in Multiple Sclerosis
Sponsor: Instituto Universitario de Oftalmobiología Aplicada (Institute of Applied Ophthalmobiology) - IOBA
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.
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

Conditions
Interventions
Eye tracking
Eye tracker will be used to evaluate eye movements
Microperimetry
Perimetric examination with Expert Exam strategy Microperimetry be used for fixation test
Optical coherence tomography (OCT)
Macular Cube 512x128 or 200x200 scan. OCT will be used to analysis of retinal nerve fiber layer, ganglion cell complex and ganglion-cell/inner plexiform layer
Visual processing speed test
Visual processing speed test will be used for assessing subject visual stimulus search and reach times. Thirty-two different everyday visual stimuli divided in four complexity groups that were presented along 8 radial visual field positions at three different eccentricities.
