• 1

  A 13-second bedside eye test may predict recovery of consciousness in patients with severe brain injuries.

• 2

• 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.

• 5

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