Background: Intracranial hypertension, which may have a number ofdifferent causes, is a medical emergency. Although difficult to identify due tonon-specific symptoms, it must be treated appropriately. An early sign of intracranialhypertension is an increase is observed in the optic nerve sheath diameter. .Ultrasonography is a rapid and easy-to-apply method to detect an increasein optic nerve sheath diameter, and may be useful for the emergency diagnosisand treatment, as well as contributing to clinical follow-up. Case Presentation: In the present study,seven patients with clinical suspicion for rapid intracranial pressure were admitted.Clinical scenarios included traffic accident, metabolic imbalance, infection, andintracranial mass. The pediatric emergency specialist performedoptic nerve sheath measurement by using ultrasonography and a dilatation wasdetected. All measurements were taken by the certified and experienced pediatricemergency specialist blinded tothe patient's clinical state and also the specialist was under observation of alecturer during the measurements. Except for one patient,the control optic sheath diameter measurements were performed in the period,when they had no complaint, and the values were determined to be normal. To ourknowledge, this case series is the first one examined in Turkey. The data from caseswas collected between 2015 and 2016. Conclusion: Optic nerve sheath diametermeasurement is a non-invasive method that offers ease of diagnosis andfollow-up of suspected intracranial hypertension.
