Intracranial Hypertension Without Papilledema in Children.

This study aims to determine the frequency of intracranial hypertension without papilledema in children. Charts of patients evaluated in a pediatric intracranial hypertension clinic at our institution were retrospectively reviewed. The patients were divided into 2 groups depending on whether they had presence or absence of optic nerve edema at the time of presentation. Age, body mass index, and opening cerebrospinal fluid pressures were considered continuous variables and compared by Wilcoxon rank sum test because of non-normality. A P-value of 0.05 was considered significant. A total of 228 charts were reviewed; 152 patients met the criteria for intracranial hypertension, and 27 patients (17.8%) met the criteria of headache without optic nerve edema. There was no clinically significant difference in age, body mass index, opening pressure, and modified opening pressure between the 2 groups.
