Pupil Test Flags Recovery Potential
13-second eye test may predict consciousness recovery after brain injury, says new research

A 13-second bedside eye test may predict recovery of consciousness in patients with severe brain injuries.
-
2
The late light-off response of the pupil predicted improvements in consciousness seven days later.
-
3
Standard pupil measurements like the Neurological Pupil Index did not predict later recovery.
-
4
The study involved 250 patients with impaired consciousness and 30 healthy controls.

The late light-off response may indicate recovery potential not visible during routine assessments.
