Innovative device uses the eyes to measure the brain

A team led by Associate Professor Bang Bui has developed an innovative proof-of-concept device which measures blood pressure dynamics in the eye to determine high intracranial pressure following head trauma.

Responding quickly to head trauma can reduce the likelihood of brain injury, however measuring intracranial pressure currently requires invasive and time-consuming surgery. This new method involves a non-invasive diagnosis, enabling physicians to determine life-saving action more quickly.

The team is now developing a handheld device that can calculate the correlation between vascular instability in the eye and intracranial pressure, which will eventually be trialled in critical care field settings.
