A study led by Lithuanian researchers identified that intracranial pressure played an important role in normal-tension glaucoma, which accounted for 50% of all glaucoma cases.
Professor Arminas Ragauskas, from Kaunas University of Technology in Lithuania, developed non-invasive intracranial pressure technology that was used in the study.
Researchers concluded that higher translaminar pressure difference (TPD) could be estimated as a risk factor for the negative development of normal tension glaucoma.
They added that as TPD was calculated by subtracting intracranial pressures from intraocular pressure, the lower the intracranial pressure measure, the higher the TPD. Therefore, in normal-tension glaucoma, lowered intracranial pressure was a possible risk factor.
