Clinical Research

Eye tracking is seeing growing use in clinical research. Eye movement analysis is studied for the identification of ocular disease, as well as mental and neural disorders such as autism spectrum disorder, ADHD, and Parkinson's disease.

Reducing variability and increasing efficiency

Eye tracking is an objective tool that increases the reliability and reduces the variability of eye tracking studies. Standardized and automated processes are more time and cost-efficient with our solutions. We give you the ability to quantify eye movement data, which makes comparison, follow-up, and progression studies more effective.

Eye tracking can improve existing clinical methods for screening and diagnostics when studying:

  • Alignment, such as in strabismus or amblyopia (lazy eye)
  • Fixation stability, smooth pursuit, or saccadic movements
  • Visual field
  • Pediatric vision issues
  • Social interaction characteristics

Neurological diseases and brain injuries

Investigating the scan patterns and control mechanisms of eye movement can provide early indicators for conditions such as autism spectrum disorder, Alzheimer's, and schizophrenia.

In research aimed at developing new means of screening neurological diseases, eye tracking paves the way for the investigation of markers (parameters that can indicate either normal function or disease). Automated assessment processes and the ability to quantify data provide new therapeutic follow-up opportunities for medical professionals. This makes it possible to follow disease or rehabilitation progression in an objective and measurable way.

Clinical areas of research include:

  • Autistic spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD)
  • Cognitive decline, such as dementia, Alzheimer's, Lewy body, and Parkinson's
  • Reading and learning difficulties, such as dyslexia
  • Stroke and non-traumatic brain injury
  • Amyotrophic lateral sclerosis (ALS)
  • Schizophrenia
  • Receptive language, expressive language, or cognitive functioning

Products and services

For clinical research, Tobii Pro offers solutions suited for labs and other controlled environments, as well as naturalistic settings in the home or the field. The eye tracking data can be synchronized and analyzed in a multitude of software environments depending on the specific needs of the researcher. Training and support for the hardware and software are provided globally.

Tobii Pro TX300

The Tobii Pro TX300 delivers a 300 Hz sampling rate with high spatial and temporal precision and accuracy. Combined with robust tracking and compensation for large head movements, the system opens up possibilities for unobtrusive research of oculomotor functions with active subjects, such as children, or with atypical populations, such as those with autism spectrum disorder. The Pro TX300 enables the study of eye movements and behaviors, such as saccades, fixations, scan paths, pupil dilation, and blinks.

The system's 16:9 format high-resolution LCD display allows researchers to present photographic and computer-generated stimuli (such as Gabor patches) over wide viewing angles. This supports visual paradigms that employ eccentric stimuli for studies of the peripheral field, as well as longer pursuit trajectories.
