THURSDAY, Oct. 30, 2025 — Doctors think they've figured out a way to predict who might lose vision due to a high brain pressure disorder. occurs when there's unexplained pressure buildup in the fluid that cushions the brain in the skull, researchers explain in the journalconnects to the retina – can predict who will develop blind spots in their vision or lose sharpness of vision.
has been increasing, and it mainly affects young women, so we need more information about who is more likely to develop vision problems and how that process works,” senior researcher Dr. Dagmar Beier, a clinical professor of neurology with the University of Southern Denmark, said in a news release.Of those, 147 had papilledema, or swelling of the optic disc due to high pressure in the cerebrospinal fluid surrounding the brain, researchers found. About 7 in 10 patients had developed scotomas, or blind spots in their vision that can be temporary or permanent, the study found. In addition, 1 in 4 had lost some sharpness of vision, also known as reduced visual acuity. All the patients received medicines to reduce their high brain pressure. After it went away, half still had scotomas and 13% still had reduced visual acuity, although none developed full-fledgedOne group's papilledema led to damage in the optic nerve fibers of the retina, causing blind spots. The other group's papilledema caused problems in the macula – the center of the retina – which resulted in lost sharpness of vision. Based on this, researchers developed a scoresheet to help doctors predict which patients with IIH will go on to develop vision problems. “This score needs to be validated by external groups before it can be considered ready for use, but we identified the severity of papilledema and the disorganization of the inner layer of the retina as major predictors for who will have persistent vision problems,” Beier said.SOURCE: American Academy of Neurology, news release, Oct. 29, 2025Eye diseases can cause damage and blindness if not treated soon enough.
