COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
In this study we are looking at using a rapid ultrasound procedure to the eye to look at the optic nerve sheath (ONS) diameter. The ultrasound scan involves gentle placement of an ultrasound probe on the closed eyelid of an unconscious, sedated patientThe ONS diameter will be compared with intracerebral pressure monitors and radiologist interpretation of CT scans to establish whether or not a detectable correlation exists.

Comparator / control treatment
Ultrasound procedure to the eye to look at the optic nerve sheath (ONS) diameter.
Group 1
Group name for participants in this group:Ventilated patients with traumatic brain injury or subarachnoid haemorrhage
Expected number of participants in this group: 50. Age range:>18 years
Group 2
Group name for participants in this group: Nonventilated
volunteers.Expected number of participants in this group: 30
Age range: >18
Other relevant characteristics of this participant group:
None
Why are these characteristics relevant to the aims of the project?
The optic nerve sheath measurements will be examined to find a normal diameter for the optic nerve sheath. We
can compare the brain injured patients to these numbers to see if there is a difference. By screening volunteers the study is looking to ensure that our readings are consistent with data published by other groups, and that we have a control group.

Outcomes
Primary outcome [1] 286214 0
Possible Outcomes
We aim to see whether, using ultrasound, a relationship exists between optic nerve diameter and brain injury in a cohort of ICU patients. In the future we would envision a role for this procedure in routine examination of injured patients, in particular in rural Australia where rapid access to expensive and bulky scanners is not always possible.

Paired t-test for comparison of brain injury group versus non-brain injured group. This will be attended a tht end of study

Summary
Brief summary
Hypothesis
Optic nerve sheath (ONS) diameter increases with raised intracerebral pressure in patients with traumatic brain injury (1) and subarachnoid haemmorhage (2) and this is detectable in intensive care patients by a rapid ultrasound examination of the eye.
