Background

Pediatric idiopathic intracranial hypertension (intracranial hypertension) is a rare but potentially vision-threatening disorder.

Purpose

This study aimed to evaluate the clinical characteristics, prognostic indicators, and outcomes in pediatric intracranial hypertension, with a specific focus on the effects of obesity and cerebrospinal fluid (cerebrospinal fluid) opening pressure.

Methods

Twenty-six children under 18 years of age, diagnosed according to the revised Friedman criteria, were retrospectively analyzed.

Results

higher spinal fluid pressure means more than triple the risk of lasting vision loss

CI excludes the null - significant

More results

The mean age was 11.2 ± 3.4 years, and 53.8% of the patients were female.

Overweight and obesity were observed in 34.6% and 19.2% of cases, respectively.

The mean cerebrospinal fluid opening pressure was 335 ± 85 mmH₂O.

More results

A significant correlation was found between cerebrospinal fluid pressure and papilledema grade (r = 0.41, p = 0.04).

Conclusion · 1 of 2

Elevated cerebrospinal fluid opening pressure and obesity appear to be associated with visual outcomes in pediatric intracranial hypertension.

Conclusion · 2 of 2

Early recognition and multidisciplinary management may help prevent irreversible visual loss and improve long-term prognosis.
