Low intracranial pressure (ICP) could play a role in the development of glaucoma among patients who have normal intraocular pressure (IOP), according to a new study.
The Lithuanian-led study, published in Diagnostics,1 examined 80 normal tension glaucoma (NTG) patients, with the aim of assessing the relationship between ICP and visual field zones.
As well as IOP and ICP, scientists calculated the difference between the pressure in the eye and the pressure in the brain, known as the translaminar pressure difference.
The researchers found that low brain pressure was associated with more significant changes to a patient’s visual field, especially in the nasal zone.
The study's authors highlighted that further research is required to understand the role of intracranial pressure as a potential biomarker in NGT patients.
“These data support additional studies to reveal the mechanistic involvement of ICP in glaucoma pathophysiology, especially as a potential biomarker for NTG,” the study authors said.

Patricia discovered she inherited glaucoma from her father after developing cataracts. She underwent a successful surgery and is now taking eye drops regularly. She now advises others to get tested early.
Researchers at University College London (UCL) and Moorfields Eye Hospital have found blood markers that can predict if glaucoma patients are likely to keep losing vision even after treatment.
Annette was diagnosed with Normal Tension Glaucoma a few years ago, and despite the challenges of managing eye pressure and a pituitary cyst, her proactive approach with treatments and family awareness gives her hope for a stable future.
