Diagnostic Value of the Optic Nerve Sheath in the Diagnosis of Increased Intracranial Pressure in Traumatic Brain Patients

BACKGROUND: Increased intracranial pressure (ICP) is a modifiable secondary injury that is associated with poor outcomes in patients with traumatic brain injuries (TBIs). Therefore, the present study was conducted with the aim of determining the ICP of TBI patients by measuring the thickness of the...

description BACKGROUND: Increased intracranial pressure (ICP) is a modifiable secondary injury that is associated with poor outcomes in patients with traumatic brain injuries (TBIs). Therefore, the present study was conducted with the aim of determining the ICP of TBI patients by measuring the thickness of the optic nerve sheath diameter (ONSD). MATERIALS AND METHODS: The present cross-sectional study was conducted on 220 patients with severe TBI that referred to Khatam-al-Anbya Hospital in Zahedan in 2021. The measurement of ONSD was performed by ultrasonography. RESULTS: The results of this study revealed that 22.7% of TBI patients had high ICP. The mean of right and left ONSD in patients with normal ICP was 3.85 ± 0.83 and 3.85 ± 0.82 mm, respectively, and was significantly lower than that of patients with abnormal ICP (high ICP) with the mean of 3.85 ± 0.82 and 6.12 ± 0.84 mm, respectively (P value <.001). In addition, the right ONSD with the cutoff point of 5.13 mm, the sensitivity of 84%, and the specificity of 95.29% and the left ONSD with the cutoff point of 5.24 mm, the sensitivity of 90%, and the specificity of 95.88% had a significant diagnostic value in the diagnosis of high ICP (P value <.05). CONCLUSION: The findings of the present study indicated that the measurement of ONSD is a cost-effective and minimally invasive procedure with a higher accuracy in diagnosing high ICP in TBI patients.
