About
Traumatic Brain Injury (TBI) is a common injury in combat, terrorist attacks and sports such as football and hockey. Unnecessary delays in the diagnosis and treatment of brain damage in patients who can benefit from evacuation procedures can lead to worse brain injury, worse outcome and, sometimes, unnecessary death. However, there is no reliable and sensitive method for diagnosis of TBI severity in the field. In this study we will examine the feasibility of using this a multifocal chromatic pupillometer for monitoring TBI, by examining the pupillary response to multifocal chromatic stimuli in intracranial pressure (ICP)-monitored severe TBI patients. As control, normal subjects will be tested for pupillary responses using this device.
Full description
To examine the feasibility of using the multifocal chromatic pupillometer for monitoring TBI, the pupillary response to multifocal chromatic stimuli will be assessed in 20 healthy subjects and 20 ICP-monitored severe TBI patients.
The portable pupillometer will be tested in 20 healthy volunteers. Their pupillary responses will be measured 3 times/day for 1 week.
Pupillary response of 20 severe TBI patients will be evaluated as detailed below at the following time points:
