ADDING MULTIMEDIA – NeurOptics Launches New NPi®-300 Automated Pupillometer

Automated pupillometry and the Neurological Pupil index™ (NPi®) emerge as critical tools for assessing patients at risk of brain injury across a broad spectrum of diagnoses

IRVINE, Calif.--()--NeurOptics, the worldwide leader in the science of pupillometry, today announced the U.S. launch of its NPi®-300, a next-generation automated pupillometer that enhances pupillary assessment to assist in detecting cerebral insult, guiding treatment and informing prognosis for clinicians and their patients.

Early detection of neurological injury is critical for effective and timely diagnosis and treatment.1 NeurOptics’ quantitative automated pupillometer provides a reliable measurement of pupil size and reactivity and tracks changes over time, allowing for earlier intervention for patients with brain injury and those at risk of secondary neurological injury. The NPi-300 Pupillometer supports neurological examination in adult and pediatric patients across a broad spectrum of diagnoses, including traumatic brain injury, stroke, seizure, or other neurological events after cardiac arrest and other medical conditions.

The new NPi-300 Pupillometer includes several enhanced features to improve functionality, including:

  • Advanced wireless charging technology, offering improved reliability for the clinician
  • Incorporated barcode scanner, allowing clinicians to easily scan a new patient’s ID accurately and instantaneously
  • Updated graphical user interface, featuring an easy-to-read LCD touchscreen that enhances the visibility of the results screen

“We are excited to launch this advanced, next-generation pupillometer,” said William Worthen, President and CEO, NeurOptics. “It is a pivotal time for pupillometry, as more hospitals, ICUs and emergency departments are adopting the technology to assess patients for changes in pupillary light reflex—a sign of neurological injury. The NPi-300 Pupillometer, along with the Neurological Pupil index™ (NPi®) scale, provides clinicians with the information needed to make better treatment decisions.”

Automated pupillometry has emerged as an important technology that provides a quantitative measurement of pupil size and reactivity, expressed as the Neurological Pupil index (NPi). NPi values range from 0 to 4.9, with scores under 3 considered abnormal. The NeurOptics NPi-300 Pupillometer eliminates the variability and subjectivity inherent in manual pupillary evaluation (performed using a penlight), providing more accurate, reliable, and objective pupil size and reactivity measurement for this vital component of neurological examinations.1-8
