February 1, 2018 – Saved by the Pupillometer! – New TBI Case Study Published in Brain Injury


ALEXANDRIA, VA – A Traumatic Brain Injury (TBI) case study was published in the latest edition of Brain Injury, the official peer-reviewed research journal of the International Brain Injury Association (IBIA).

The study, Saved by the Pupillometer!- A role for pupillometry in the acute assessment of patients with traumatic brain injuries?, was authored by J Emelifeonwu, K Reid, J Rhodes and L Myles from Western General Hospital, Edinburgh, UK.


The authors describe the clinical course of a patient with an acute traumatic subdural hematoma determined by manual pupil assessment to have non-reactive pupils. Upon transfer to the NeuroICU for brainstem death testing, objective pupillometry determined the patient’s pupils were in fact reactive. He made a good recovery following subsequent surgery to evacuate his subdural hematoma. The authors conclude objective pupillometry, and in particular the NPi® (Neurological Pupil index™), provides a rapid, non-invasive and objective method of pupil assessment in patients with TBI.
