  2. TBI is one of the most prevalent and crippling conditions affecting our nation today. Assessment of TBI severity is crucial in appropriate therapy and patient outcome. Today’s presentation focuses on the relationship between pupil size measures like NPI, percent change in pupil size, constriction velocity, and pupil dilation velocity and how these all relate to TBI Severity. We hope to illuminate this important area in TBI care that could make all the difference in patients’ lives as well as healthcare providers. ©Copyright by Neuroptics.com

  3. Pupil Response & TBI Pupillary response is one of the critical determiners of TBI. It is a fact that the eyes are called the “windows of the soul” for a reason and it holds true. Research shows that a rise of about 30 percent in the percent changes occurred in pupillary size post-TBI. This phenomenon does not just happen by chance, but rather, serves as a dependable indicator of the TBI severity level. Traumatic brain injury disturbs the fine balance of the autonomous nervous system which controls pupil function. Anisocoria is a typical indication of the affected pupil either dilating slowing or failing to contract when it ought to. A small but important adjustment in the pupils’ size may have even deeper and much bigger problems with the brain. ©Copyright by Neuroptics.com

  4. Neurological pupil index (NPI) NPiis definetly one of the most sought after evolution in neurological advancement and now a days it is becoming a crucial part of assessing onstriction velocity, and pupil dilation velocity. Constriction velocity: This is the assessment of how fast the pupil contracts in response to light. In fact, in many cases, a slow constriction velocity implies a much worse head trauma. ©Copyright by Neuroptics.com

  5. Pupil dilation velocity: It is equally important to evaluate the speed at which a pupil moves back to its typical dimension once the illumination stimulus is withdrawn. Slower dilating pupils indicate that it takes longer for the pupil to return to its normal state. Such late reaction can be used as one of the indicators of TBI gravity and possibly can be related to other neurologic anomalies. Traumatic brain injury severity is linked closely with a percent change in pupil size. The use of the Neurological pupil index is proving to be life life-changing evolution. This data is allowing healthcare professionals an early intervention and enabling tailored treatments. ©Copyright by Neuroptics.com
