Eye test may predict consciousness recovery after brain injury, study finds

The research involves 250 patients with severe brain injuries and impaired consciousness, directly impacting prognosis and treatment planning for this vulnerable population.

In the hushed uncertainty of the intensive care unit, where families wait and clinicians search for signs of return, a subtle flicker in the eye may now speak what no standard test has been able to say. Researchers at Copenhagen University Hospital Rigshospitalet have identified a previously overlooked phase of the pupil's response to light — the late light-off response — that independently predicts whether a severely brain-injured patient will regain consciousness within a week.
