Measurement of the Optic Nerve Sheath Diameter
- Conditions
- Optic Nerve
- Interventions
- Procedure: Ocular Ultrasound
- Registration Number
- NCT05548335
- Lead Sponsor
- Cleveland Clinic Akron General
- Brief Summary
This study is a prospective assessment of the accuracy of ocular ultrasound as a tool to measure the diameter of the optic nerve sheath and the eyeball transverse diameter in healthy adult patients presenting to the Emergency Department and have confirmatory imaging of the optic nerve as part of their clinical care.
- Detailed Description
This will be a prospective evaluation of accuracy of microconvex and linear transducers for ultrasound measurements of the ONSD and the ETD. Study population will be adult patients that present to Cleveland Clinic Akron General Emergency Department between July 1, 2022 and July 31 April 1, 2023. Patients will be identified on the Emergency Medicine Department tracking board. Patients, once identified as meeting inclusion criteria will be asked to participate in this study and full written consent will be required. All participants will have identical procedures and there will be no groups.

Group Intervention Description Ocular Ultrasound Ocular Ultrasound This arm includes all patients enrolled who will have an ocular ultrasound with two different probes for a total of four ultrasounds.
- Primary Outcome Measures
Name Time Method The Primary objective is to determine the accuracy of the microconvex ultrasound transducer as compared to the linear ultrasound transducer for ultrasound measurement of the optic nerve sheath diameter compared to CT measurements. through study duration, one year is anticipated. The patient will be enrolled and be involved with the study for 15-20 minutes. At this time the research procedures will be done.
- Secondary Outcome Measures
Name Time Method To determine the accuracy of the microconvex ultrasound transducer as compared to the linear ultrasound transducer for ultrasound measurement of the ONSD/ETD compared to CT measurements. through study duration, one year is anticipated. The patient will be enrolled and be involved with the study for 15-20 minutes. At this time the research procedures will be done.
To determine the level of intra- and inter-rater variability for ultrasound measurement of the optic nerve sheath diameter between the two transducer types. through study duration, one year is anticipated. The patient will be enrolled and be involved with the study for 15-20 minutes. At this time the research procedures will be done.
