[Intracranial pressure and non-invasive pressure modalities]

As summarised in this review, the need for intracranial neuromonitoring is crucial in patients with elevated intracranial pressure (ICP) regardless of aetiology and geographic location. ICP monitoring still relies heavily on invasive measure modalities. Non-invasive pressure modalities would exclude some of the difficulties of the invasive: procedure-related complications and accessibility. However, non-invasive modalities have not been implemented due to lack of precision and varying results in clinical studies. New research in retinal vessel dynamics have shown promising results.
