TitelSuspected optic disc oedema in children – how helpful is ultrasound optic nerve sheath diameter measurement?
Abstract Nr.P130
DoelTo determine the role of Optic Nerve Sheath Diameter (ONSD) measurement by Ultrasound (US) in the context of possible raised intracranial pressure (ICP) in children.
MethodesRetrospective case series review in a large university medical center in the Netherlands. A large US-ONSD database was manually searched for cases (age range 0-16yrs) in which the aspect of the optic disc raised suspicion of oedema and for whom an US-ONSD measurement was requested. Paediatric case notes were scrutinized for relevant, and esp. missed, diagnoses with concomitant raised ICP after the ONSD measurements.
ResultatenOut of 93 cases 46 had an ONSD of 5 mm or more. 9 of these had syndromes with raised ICP. Out of the remaining patients with an ONSD of less than 5 mm 1 was diagnosed with raised ICP. The negative predictive value for raised ICP with an ONSD of less than 5 mm or less was 98%.
ConclusieUS-ONSD measurement appears a useful tool to rule out, rather than confirm, raised ICP in children with suspected optic disc oedema.
