The specificity and sensitivity values were determined as 98.1% and81.8%, respectively, for a cutoff value of 5 mm and as 100% and 72.7%, respectively, for a cutoff value of 6 mm.Conclusion: This study showed that bedside measurement of ONSD is an easy, cheap, and noninvasive method that can be used tosupport the diagnosis and evaluation of patients with acute stroke.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:Background/aim: We aimed to show the role of determination of optic nerve sheath diameter (ONSD) by bedside ultrasonography inan emergency department in the diagnosis of cerebrovascular disorders and its correlation with the clinical picture.Materials and methods: This prospective cross-sectional study included 55 patients with cerebrovascular disorders and 53 controls.Age, sex, ONSD, comorbid disease status, and multidetector computed tomography results of all subjects and application periods andNational Institutes of Health Stroke Scale (NIHSS) scores of the patient group were evaluated.Results: The ONSD of the patient and control groups was determined as a median of 5.7 mm and 3.6 mm, respectively.
📊
Key Findings & Data:The ONSDof the patient group was determined to be significantly higher than that of the control group (P < 0.05).

Abstract
Background/aim: We aimed to show the role of determination of optic nerve sheath diameter (ONSD) by bedside ultrasonography inan emergency department in the diagnosis of cerebrovascular disorders and its correlation with the clinical picture.Materials and methods: This prospective cross-sectional study included 55 patients with cerebrovascular disorders and 53 controls.Age, sex, ONSD, comorbid disease status, and multidetector computed tomography results of all subjects and application periods andNational Institutes of Health Stroke Scale (NIHSS) scores of the patient group were evaluated.Results: The ONSD of the patient and control groups was determined as a median of 5.7 mm and 3.6 mm, respectively. The ONSDof the patient group was determined to be significantly higher than that of the control group (P < 0.05). A positive relationship wasdetermined between NIHSS scores and ONSD values (P < 0.05). The specificity and sensitivity values were determined as 98.1% and81.8%, respectively, for a cutoff value of 5 mm and as 100% and 72.7%, respectively, for a cutoff value of 6 mm.Conclusion: This study showed that bedside measurement of ONSD is an easy, cheap, and noninvasive method that can be used tosupport the diagnosis and evaluation of patients with acute stroke.
