Optic nerve ultrasonography in monitoring treatment efficacy in pediatric idiopathic intracranial hypertension

Combined accuracy of optic nerve sheath diameter, strain ratio, and shear wave elastography of the optic nerve in patients with idiopathic intracranial hypertension

“…Ultrasonography is commonly used to measure ONSD in the assessment of IIH patients as an easy bedside tool. ONSD is considered an indirect, noninvasive measure of ICP, making it a useful parameter in the clinical diagnosis of IIH [ 15 - 17 ]. The measured ONSD was significantly higher in the IIH group than in the control group (P=0.001).…”

“…We would like to thank you for the opportunity to respond to the issues raised in Vitiello et al's letter. We also would like to thank Vitiello et al [1] for their opinion about our recent article [2] published in Child's Nervous System.…”

“…ONSD in orbital ultrasonography regressed gradually consistent with clinical and radiologic improvement during follow-up. [2] We agree with you that B-scan orbital USG has some handicaps related to technique, patient, and clinicians, which were mentioned in the discussion section of our text and Vitiello et al's letter [3][4][5]. To avoid these disadvantages, ONSD assessments were performed on axial images, which were recorded 3 mm posterior to the anterior of the optic nerve head, three measurements were obtained in each eye, and their averages were recorded and the cut-off the ONSD enlargement was considered as ONSD of ≥ 5 mm in the present study.…”

Is Ocular Sonography a Reliable Method for the Assessment of Elevated Intracranial Pressure in Children?

“…Furthermore, it was found that the ONSD measurements for both eyes were statistically significantly higher in the patient group. Orgun et al 40 assessed the role of the ONSD measurement by ocular ultrasonography in eight pediatric subjects diagnosed with idiopathic intracranial hypertension. Despite the small sample size, they suggested that orbital ultrasonography was a promising noninvasive technique for the diagnosis of elevated ICP and monitoring of the efficacy of treatment in this population.…”
