Outcome of pediatric patients referred for papilledema

Purpose To determine the prevalence of papilledema versus pseudopapilledema among children referred for suspected papilledema and to identify clinical factors differentiating the two diagnoses. Methods This is a prospective, cross-sectional analysis of patients Results A total of 34 patients were identified. Of these, 26 patients were diagnosed with pseudopapilledema or a normal variant; 2, with papilledema; and 6, with unrelated or indeterminate etiology. Headache was a presenting symptom in 25 patients. Five patients complained of additional symptoms suggestive of increased intracranial pressure, of whom 2 were patients diagnosed with papilledema. Conclusions The incidence of true papilledema among children referred for suspected papilledema based on fundus examination is very low. Headache is a common nonspecific symptom in most patients, whether or not they have papilledema. If children have no additional signs and/or symptoms suggestive of elevated ICP or vision loss, the need for evaluation of such children is not urgent. A detailed history and examination coupled with noninvasive testing, such as ultrasonography, will generally distinguish pseudopapilledema from other abnormal-appearing optic nerves.
