Study summary

The study is a prospective, multi-center, non-randomized, open label observational study. The objective of this study is to compare the accuracy of the EyeBOX to a clinical diagnosis of abnormal ICP as determined by an external ventriculostomy drain (EVD) or ventriculostomy catheter.

Study population

The study will enroll pediatric and adult patients with abnormal ICP. Subjects who meet all of the inclusion criteria and none of the exclusion criteria will be considered for enrollment into the study. There will be no enrollment restrictions based on race, ethnic origin, gender, or pregnancy status and efforts will be made to ensure that the benefits and burdens of research participation are distributed in an equitable manner. Subjects must require ICP monitoring for clinical indications. At the time when eye tracking is performed all patients must be awake with spontaneous eye opening.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Provide written .
  2. Require placement of an ICP monitor or ventriculostomy catheter for clinical purposes.
  3. Be between the ages of 4 and 70 years old.
  4. Have baseline vision correctable to within 20/500 bilaterally.
  5. Have no prior history of ocular dysmotility.
  6. Be awake with spontaneous eye opening at the time when eye tracking is performed.

Exclusion criteria

Exclusion Criteria:

  1. Have a prior history of strabismus, diplopia, or palsy of CN-III, IV or VI.
  2. Be blind (no light perception), have missing eyes, be unable to open their eyes.
  3. Have a prior history of ocular motility dysfunction.
  4. Have had extensive prior eye surgery.
  5. Have any physical or mental injury or baseline disability rendering task completion difficult.
  6. Be intoxicated or have blood alcohol level greater than 0.2.
  7. Be a prisoner or in the company of a police officer or law enforcement officer pending arrest.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2018 to primary completion in May 2023, 60 months.

Of 44 observational studies under Intracranial Hypertension, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 62. This study's 60 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 7, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
