Non-invasive intracranial pressure estimation using periorbital vein occlusion pressure

Official title: Non-invasive Intracranial Pressure Estimation by Measurement of the Occlusion Pressure of the Isolated Periorbital Vein (NICE-ICP)

Run by Compremium AG · NCT07222826 · Data updated 2026-11-12

This test tries to estimate intracranial pressure without surgery by measuring occlusion pressure in the vein around the eye in adults who already have an invasive ICP monitor.

Is this trial a fit for you?

Likely a good fit

Ideal participants are adults (over 18) hospitalized with a clinically placed invasive ICP monitor and without facial/skull trauma, recent cranial surgery, orbital venous disease, or active bleeding.

Probably not a fit

Patients with facial or skull trauma, recent cranial surgery or hemicraniectomy, orbital pathology or known ophthalmic vein stenosis, active bleeding, or those not already fitted with an invasive ICP monitor will likely not benefit or be eligible.

What this trial studies

The procedure uses a pneumatic mask and ultrasound to isolate and measure the occlusion pressure of the periorbital vein, aiming to derive a non-invasive estimate of intracranial pressure. Measurements are performed in hospitalized adults who already have an invasive ICP monitor so the new method can be directly compared to gold-standard readings. Patients with facial or skull trauma, recent cranial surgery, orbital venous disease, or active bleeding are excluded to avoid interference with measurements. The trial is conducted at Baylor College of Medicine and uses concurrent invasive ICP readings as the reference standard.

Why it matters

Potential benefit: If successful, this method could allow reliable, non-surgical ICP monitoring and reduce the need for invasive catheters and their associated risks such as infection and bleeding.

How similar studies have gone: Other non-invasive ICP techniques (for example optic nerve sheath diameter or transcranial Doppler) have shown mixed results, and periorbital vein occlusion pressure is a relatively novel approach with limited prior clinical validation.

Inclusion Criteria:

* Male or female
* Age \> 18
* Equipped with an invasive ICP monitor as part of standard of care

Exclusion Criteria:

* Presence of facial and/or skull trauma that could hinder placement of the pneumatic mask or contraindicate ultrasound on the forehead
* History of recent cranial surgery or hemicraniectomy
* Active bleeding (proven or suspected)
* History or known pathological condition or injury linked to the orbital socket influencingvenous outflow (e.g. Grave disease, tumor, inflammation, trauma, glaucoma, etc.)
* History, or known vein stenosis in ophthalmic veins/cavernous sinus
* Any other condition that would interfere with measurement technique and routine clinical care according to the judgment of the investigator.
