Patterns of rapid eye movement, pupil dilation and blinks provide measures of certain thinking processes and can provide insight into early signs of brain dysfunction.

ONDRI protocol

Participants are asked to perform a structured and an unstructured task, while sitting in front of a computer screen.

The structured task consists of looking at, or looking away from, dots on a screen, following specific and detailed instructions. The unstructured task consists of participants watching video clips, similar to how they watch TV.

Video-based eye tracking records and measures their eye movement, pupil size and blink occurrence, as they perform these activities.

This assessment was used in the following studies:
