Pupillary assessments can aid in the early detection of neurological injuries or diagnoses including brain trauma, stroke, seizure or events that follow medical conditions such as cardiac arrest. The sooner these issues are identified the quicker treatment decisions can be made, to help preserve vision and prevent lasting damage. NeurOptics recently released an automated pupillometer called the NPi-300 that the company says can help assess changes in pupillary light reflex, one of the common indications of neurological injury.
The device uses an infrared camera to measure pupil size and reactivity. These factors are then compared against a normative database to generate a composite score using an algorithm called the Neurological Pupil index (NPi), developed by the company, with values ranging from 0 to 4.9 (<3 is considered abnormal). Expressing this data numerically allows it to be tracked over time, which may allow doctors to make better and more informed treatment decisions, NeurOptics says.
