US EditionEarly Warning Signs of Vision Loss From Brain Disorder Identified
Researchers created a scoring system identifying papilledema severity and retinal changes as key predictors of lasting vision problems in idiopathic intracranial hypertension patients.
- On October 29, 2025, researchers published in Neurology an assessment to help physicians predict vision problems in people with intracranial hypertension at diagnosis.
- Idiopathic intracranial hypertension often develops without symptoms, causing chronic headaches and vision problems, with obesity as the primary risk factor and untreated cases risking vision loss, study author Dagmar Beier, MD noted.
- The study involved 154 people with intracranial hypertension , including 147 people with papilledema; 69% had scotomas and 26% had reduced visual acuity.
- Researchers found two mechanisms causing vision problems: one linked higher papilledema to optic nerve fiber layer thinning and scotomas, another involved severe papilledema with macula issues; follow-up showed 50% had scotomas, 13% reduced acuity, none blinded.
- Beier cautioned that the study's limitations include the need for external validation, as she said, `'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.

New study sheds light on vision loss in idiopathic intracranial hypertension
If untreated, a disorder of high brain pressure called idiopathic intracranial hypertension can lead to vision loss. But this disorder can develop without noticeable symptoms, making it hard to catch.

How A Brain Pressure Disorder Causes Vision Loss — And Who Might Be Affected
Key Takeaways
Who is more likely to lose vision due to high brain pressure?
If untreated, a disorder of high brain pressure called idiopathic intracranial hypertension can lead to vision loss. But this disorder can develop without noticeable symptoms, making it hard to catch. A new study looks at how these vision problems develop and proposes a way to predict who will develop issues. The study is published on October 29, 2025, in Neurology.
Who is more likely to have vision loss in high blood pressure?
A new study has shed light on how vision problems develop in people with a condition called idiopathic intracranial hypertension (IIH), and it offers a new way to predict who is most at risk. The study was published on October 29, 2025, in the journal Neurology. IIH happens when pressure builds up in the fluid […] The post Who is more likely to have vision loss in high blood pressure? appeared first on Knowridge Science Report.
