Background:Traumatic brain injury (TBI) and spinal cord injury (SCI) are crucial worldwide health priorities.These injuries result in human dysfunction and health loss, as well as being a burden on health-care systems and economies due to high health-care cost and lost productivity.This study aimed to correlate the findings between the optic nerve sheath diameter (ONSD) with the intracranial pressure (ICP) value by the invasive ICP monitoring catheter along with evaluating the cut off value of ONSD measurement in predicting raised ICP, with its specificity and sensitivity value. Patients and Methods: The prospective study included patients >18 years of age and with a suspected traumatic brain injury with an initial (Glasgow Coma Scale) GCS of ≤12. Brief history, clinical examination findings and relevant investigation reports were recorded. Data was analyzed in R software version 4.1.0.P≤0.05was set as statisticallysignificant.
Result: By using paired t test, we observed that there was significant difference in mean ICP from 0 hour to 12 hours. However, the variance in mean ICP from 0 hour to 24 hours was insignificant.ONSD and ICP was significantly correlated at 0 hour, 12 hours and 24 hours.
Conclusion: Increased value of optic nerve sheath diameter (ONSD) was helpful in predicting elevated intracranial pressure (ICP).
