Exploring biomarkers in clinical research

There is a strong connection between deficits in eye movements and various underlying brain disorders and injuries. Clinical researchers use eye tracking to explore biomarkers for cognitive impairment, enabling new tools for diagnosis, rehabilitation, and treatment.

Why use eye tracking?

Eye tracking is a non-invasive, objective, and reliable method providing a proxy for oculomotor and cognitive functions. It allows access to cognitive functions or psychological states without needing overt behavioral responses like button presses or verbalization, which is crucial for assessing individuals with low focus or the ability to sustain lengthy standard tests.

What you can measure with eye tracking

Eye tracking solutions with a dedicated application, like our software Tobii Pro Lab, can further process the data to draw valuable conclusions on cognitive, behavioral, and oculomotor deficits, including:

Tobii Pro Spark

Attention allocation

Measure attentional processes using fixation duration and location.

Executive functions

Study the brain's ability to execute or suppress reflexive eye movements with saccade and anti-saccade tests.

Fixations eye movements

Oculomotor system

Measure a person’s ability to fixate on a moving object using smooth-pursuit tasks.

Emotional valence and arousal

Assess emotional responses and cognitive workload based on pupillary responses.

Reading ability

Capture dyslexia or age-related changes in reading behavior during a reading task.

Fields of research

Eye tracking can measure subtle eye movements that are linked to cognitive impairment and has become instrumental in clinical research, in areas such as:

  • Neurodegenerative disorders

    Alzheimer’s, Parkinson’s, and Huntington’s.

  • Neuropsychiatric disorders

    Depression, anxiety, schizophrenia, and eating-disorders.

  • Neurological conditions

    Concussion, traumatic brain injury, and stroke.

  • Ophthalmology

    Visual field, lazy eye, and strabismus.

Research setups for clinical studies

Standalone for the lab

If your study requires that patients observe or interact with physical objects or another person, you can use Tobii Pro Spectrum in standalone mode. Works together with Tobii Pro Lab to deliver insights on behavior.

Clinical research

Wearable for the real world

Designed for on-the-go data capture, our Tobii Pro Glasses 3 wearable eye tracker allows patients to interact and move around freely, and enables you to design studies that closely reflect real-world scenarios — for the lab and the field.
