Study Summary
The purpose of this study is to explore the inter-device reliability between the NPi-200 and NPi-300.
Primary Outcome
Pupil's reaction to light as measured by Neurological Pupil Index (NPI) algorithm using pupillometer device that grades the pupil's reaction to light on a scale between 0 and 5. The Inter-device reliability is assessed using Cohen's Kappa method: values ≤ 0 as indicating no agreement.
Interventions
- DEVICE NPi-200 and NPi-300 pupillometers
