Ultrasonographic Measurement of Optic Nerve Sheath Diameter for Detection of Increased Intracranial Pressure in Patients Scheduled for Elective Tumor Craniotomy

Comparative study between ultrasound guided coronal versus axial optic nerve sheath diameter measurement in patients at risk of increased intracranial pressure

“…According to Mathews et al, [15] , who witnessed the same thing as we did, every patient who had previously had loss of consciousness, post-traumatic vomiting, and posttraumatic seizures showed intracranial pathology with raised ICP and expanded ONSD that was shown on a CT scan of the brain. Similarly, Othman et al [16] , determined that those with higher ICP radiological findings on CT included those who had prior headaches, vomiting, and visual field impairment. Fernando et al [17] , in contrast to our findings, discovered that certain physical indicators of high ICP were insufficiently sensitive to identify the illness.…”

“…Additionally, Mabrouk et al [21] discovered a strong correlation between the mean ONSD and the severity of TBI. In addition, Othman et al [16] found that patients with clinical symptoms of elevated ICP, such as nausea, vomiting, headaches, disrupted conscious level, and visual field affection, had a statistically significant increase in mean ONSD. It is advised that this non-invasive, easily accessible, quick, straightforward, and bedside diagnostic modality may be useful in a variety of clinical settings, such as pre-hospital care, military settings, centres without CT scans, long transport times, disaster scenes, intensive care unit settings, and even in the operating room, especially in the developing world where the availability and utilisation of invasive monitoring is limited.…”
