Measuring optic nerve sheath diameter to assess neurological deficits in stroke patients
Correlation Between Optic Nerve Sheath Diameter Measured by POCUS and Neurological Deficit in Physical Examination in Adult Patients with Suspected Ischemic Stroke Evaluated in Emergency Departments
This study tests if measuring the optic nerve sheath diameter with ultrasound can help doctors understand neurological problems in adults who might be having a stroke.

What this trial studies
This observational study aims to evaluate the correlation between the ultrasound measurement of the optic nerve sheath diameter and the side of neurological focus in adult patients presenting with suspected ischemic stroke in emergency departments. The study will involve adult patients who meet specific inclusion criteria, and will utilize high-frequency ultrasound to measure the optic nerve sheath diameter. Data collected will include demographic, clinical, and ultrasound information to analyze the relationship between the measurements and neurological deficits.
Who should consider this trial
Good fit: Ideal candidates are adult patients (≥18 years) presenting to the emergency department with suspected acute ischemic stroke.
Not a fit: Patients with contraindications for ocular ultrasound or a history of previous ocular surgery may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance the diagnostic accuracy for identifying the side of neurological focus in patients with suspected ischemic stroke.
How similar studies have performed: While the use of optic nerve sheath diameter measurement in stroke assessment is gaining interest, this specific correlation has not been extensively tested in prior studies.
