Implementation of a Novel Functional Eye-Tracking Biomarker for Multiple Sclerosis

UnknownN/A

Sponsor: McGill University

Conditions: Clinically Isolated Syndrome, Relapsing Remitting Multiple Sclerosis

Interventions: Eye-tracking

Countries: Canada

This study aims to develop and validate a sensitive and non-invasive eye-tracking software application. This study will obtain participant responses to brief cognitive tests designed to evaluate several key functions known to be affected by CIS and RRMS and non-invasive eye movement measurements in response to visually presented stimuli during specifically designed eye-tracking tests. The study data will be used to develop machine learning algorithms and validate a software application intended to identify which metrics-or combination thereof-can serve as reliable biomarker of CIS and RRMS disease progression and cognitive status.

Eligibility overview

Sex: ALL

Age: 18 Years to 65 Years

Healthy volunteers: Yes

Study type: OBSERVATIONAL

Eligibility criteria

Inclusion Criteria:

* For all participants

  1. Able to provide informed consent
  2. Visual acuity of 20/100 in at least one eye (corrective glasses, contact lenses, surgery etc. are permitted)
* For patients only

  1. Confirmed diagnosis of CIS with abnormal MRI or RRMS
  2. Neurological condition is medically stable during the study visit

Exclusion Criteria:

* For all participants:

  1. Evidence or medical history of psychiatric issues, which are known to also affect movements and oculomotor control.
  2. Aged above 65 or less than 18 years of age.
  3. Presence of comorbid neurological conditions to avoid eye movement anomaly confounds (Strabismus, cranial nerve palsy, stroke-causing hemianopsia).
  4. Diagnosis of macular edema or other pre-existing ocular conditions that would prevent from performing the eye movement assessments.
* For healthy controls only:

  1. Evidence or history of significant neurological disorder (Multiple Sclerosis, Parkinson's Disease, Amyotrophic Lateral Sclerosis, Dementia)
