Eye Movements Recording Using a Mobile : Comparison to Standard Video-oculography in Young Athletes

Association de Recherche Bibliographique pour les Neurosciences46 enrolled

Overview

This study aims to compare measurements obtained through the e-VOG application (mobile application, usable on smartphones or tablets, to measure eye movements) with measurements from the standard video-oculography device (Eye-Tracker®T2), in young athletes.

e-VOG Young athletes is a collaborative study between the Memory Center of the Rainier III Center (Princess Grace Hospital, Monaco), the Neurology Department of Nice University Hospital (France), and the AS Monaco Football Academy medical team. Memory Center of the Rainier III Center is expert in eye-tracking and is equipped with a standard video-oculography device (Eye-Tracker®T2), which records eye movements at a high frequency and measures saccades parameters (latency, speed, amplitudes etc...). e-VOG is a mobile application, home-developed by the Neurology Department team of Nice University Hospital, to measure eye movements. Based on literature, investigators hypothesize that video-oculography could integrate assessment protocols for head trauma occurring during sports practice. The nomadic nature of the e-VOG application would make possible to assess oculomotor behaviors to a subject who has just suffered a trauma and who is suspected of having a concussion. From this perspective, it seems necessary to firstly validate baseline values of the e-VOG application in a population of athletes without major health problems, and who have not presented concussion.

Outcomes

Primary Outcomes

Oculomotor profiles concordance

Analyze of the concordance of the profiles obtained between the e-VOG digital assessment and the standard video-oculography assessment. Evaluation criteria: For each assessment, patients will be classified according to the number of oculomotor abnormality observed (based on identified parameters assessments: latency / speed / gain / altered ocular pursuits / fixation disorders / presence of internuclear ophthalmoplegia), in accordance with the literature standards.

Time frame: Day 0

Secondary Outcomes

Latency during horizontal reflex saccades

Measure of Latency during an horizontal reflex saccades paradigm with e-VOG Compared to the one performed with standard video-oculography device. Evaluation criteria: latency (reaction time in ms).

Time frame: Day 0

Latency during vertical reflex saccades

Measure of Latency during a vertical reflex saccades paradigm with e-VOG Compared to the one performed with standard video-oculography device. Evaluation criteria: latency (reaction time in ms).

Time frame: Day 0

Latency during horizontal voluntary saccades

Measure of Latency during an horizontal volontary saccades paradigm with e-VOG Compared to the one performed with standard video-oculography device. Evaluation criteria: latency (reaction time in ms).

Time frame: Day 0

Velocity during horizontal reflex saccades

Measure of Velocity during an horizontal reflex saccades paradigm with e-VOG Compared to the one performed with standard video-oculography device. Evaluation criteria: velocity (mean and peak velocity) in °/s.

Time frame: Day 0

Velocity during vertical reflex saccades
