Optic nerve sheath diameter with intracranial pressure monitoring: a non-invasive method to follow children with craniosynostosis.

Craniosynostosis (CS) is associated with increased intracranial pressure (ICP) and this elevation is of vital importance in children. Bedside optic nerve sheath diameter (ONSD) on ocular ultrasonography has begun to be increasingly used in recently. A patient who was diagnosed with CS, standard anesthesia monitoring and anesthesia were performed. Before and after the surgery, ONSD measurement was performed to follow the changes in ICP. ONSD measurement can be used as an effective, non-invasive, repeated, and easy-to-apply method to monitor the changes in the ICP in pediatric patients with CS who are planned to undergo craniectomy.
