简要总结
Assessment and monitoring of intracranial pressure (ICP) changes are important in the management of cerebral pathologies. In the eye, ICP increase and decrease both correlate with optic neuropathies, the former because of papilledema and the latter related to glaucoma. While the relationship between ICP elevation and papilledema is well established, the relationship between low ICP and glaucoma is still poorly understood. So far, ICP monitoring is performed invasively, but this entails risks including infection, spurring the study of non-invasive alternatives. While none of currently methods in use can fully replace invasive techniques, certain measures show great potential for specific applications. In this context, monitoring the intracranial pressure changes of normal tension glaucoma may lead to a better understanding of how intracranial pressure waves vary in normal tension glaucoma. Treatment of normal tension glaucoma as a two-pressure disease needs periodic intracranial dynamic monitoring sessions for evaluation of treatment effectiveness and for needed corrections of treatment methodology.
Project aim is to be able to monitor the "missing link" of intracranial dynamics of patients with normal tension glaucoma according to circadian rhythm: in the morning, during lunch and in the evening. The opportunity to monitor ICP waves non-invasively for patients with normal tension glaucoma will be implemented for the first time by using novel non-invasive intracranial pressure waves real-time monitoring system invented by KTU team in 2022 (patent applications are in the process of registration in the EU and USA).
