title: Prevalence of idiopathic intracranial hypertension and associated factors in obese children and adolescents.
abstract: BACKGROUND
  Idiopathic intracranial hypertension (IIH) is one of the most important and rare complications of obesity. Prevalence of IIH in childhood obesity is not known. The purpose of this study was to determine the prevalence of IIH in obese children and adolescents and to investigate the relevant factors.
  
  
  METHODS
  In this study, 1058 obese children and adolescents between 2 and 18 years of age were included. Funduscopic examination was conducted for all subjects. In cases with papilledema, increase in intracranial pressure was clarified by measuring CSF pressure with a lumbar puncture. Other causes of IIH were ruled out with clinical, laboratory tests and imaging techniques.
  
  
  RESULTS
  Idiopathic intracranial hypertension was diagnosed in 14 subjects (1.32%). Rates of headache and systemic hypertension in subjects with IIH was determined to be 78.6% and 28.6%, respectively. Morning cortisol, fasting insulin and HOMA-IR values were found to be significantly higher in this cases (p<0.05).
  
  
  CONCLUSIONS
  In childhood obesity, IIH should be kept in mind as a serious complication. Funduscopic examination is an easy method that suggests IIH. In particular, obese children with systemic hypertension and refractory headache should be considered for IIH.
