“…The transbulbar sonography technique for the estimation of ICP by measuring ONSD of children was first described by Helmke et al (9). So far, several studies evaluated the reliability of ONSD measurements by concurrent magnetic resonance imaging and invasive methods (10)(11)(12). Steinborn et al (13) observed 99 healthy children and adolescents in order to determine the normal values of ONSD.…”

Abstract Background: Mouth gag is usually used during Adeno/tonsillectomy surgeries, cleft palate repair, obstructive sleep apnea surgery and intraoral tumor excision. The placement of gag causes hemodynamic changes similar to laryngoscopy. The aim of this study is to evaluate the effect of mouth gag placement on optic nerve sheath diameter (ONSD) of pediatric patients. The secondary aim is to assess the relationship between neck extension for positioning of head and increase in ONSD measurement. Methods: The trial is registered to Australian New Zealand Clinical Trials Registry with Trial ID: ACTRN12618000551291. This prospective, observational study was performed in a tertiary university hospital operating theatre between 01.05.2018-01.07.2018. Thirty-five children aged < 18 years, with ASA I status, and scheduled for adeno/tonsillectomy surgeries were prospectively included in the study. Measurements of ONSD were performed (T0) after induction of anesthesia, (T1) after endotracheal intubation, (T2) after the placement of mouth gag and (T3) 20 minutes after the placement of mouth gag. The degree of neck extension was assessed by the angle between the Frankfort plane and horizontal plane of the operation table in natural position Results: All participants completed the study. There were significant differences in ONSD values according to time (p < 0.001). The maximum increase in ONSD values was detected after intubation (0.69±0.06 mm) and immediately after mouth gag placement (0.67±0.07 mm). ONSD values continued to increase 20 minutes after the gag placement. There was no relation between degree of neck extension and ONSD values (b = 0.63, p=0.715) Conclusions: Mouth gag application causes significant increases in ONSD measurements of children. Therefore, the duration of mouth gag application during surgeries might be limited. Trial registration: The trial is registered to Australian New Zealand Clinical Trials Registry with Trial ID: ACTRN12618000551291.

“…These methods have been used to detect elevated ICP with sensitivity and specificity ranging from 84 to 98% and 42 to 92%, respectively (►Table 1). [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] The values can be compared with the results of two different meta-analyses from 2011 and 2015 that demonstrated the ability of ONSD ultrasonography to yield average sensitivity and specificity ranging from 90 to 95% and 85 to 92%, respectively. 29,30 A more recent meta-analysis found sensitivity and specificity to range from 88 to 95% and 74 to 96%, respectively.…”

Idiopathic intracranial hypertension (IIH) is characterized by isolated rise in intracranial pressure (ICP) leading to chronic, debilitating headaches, tinnitus, and vision loss. Conventional diagnostics and monitoring primarily require the use of invasive procedure like lumbar puncture to measure ICP, while traditional management strategies involve weight reduction and medical treatment with acetazolamide. In an effort to reduce the need for invasive procedures, noninvasive methods of ICP monitoring such as optic nerve sheath diameter measurements and two-depth transcranial Doppler ultrasonography have been developed. In cases of refractory and fulminant IIH, surgical management strategies such as optic nerve sheath fenestration (ONSF), ventriculoperitoneal (VP) and lumboperitoneal (LP) shunting, and transverse venous sinus stenting are used to relieve symptoms via ICP reduction. While ONSF and VP/LP shunting exhibit utility primarily for the treatment of vision loss and headache, respectively, venous sinus stenting may prove to be an effective option in the management of all symptoms of IIH. Most importantly, consideration of the patient’s individual symptoms and values should be taken into account when choosing the optimal surgical management strategy for patients with IIH.

“…Measurement of ONSD using ocular ultrasound is a noninvasive and reliable method for the assessment of ICP. Numerous studies have proven that ONSD measured by ocular ultrasound correlates well with the degree of ICP changes [9][10][11][12][13]. Also, this measurement technique has shown excellent intra-observer and inter-observer reproducibility (0.25-0.3 mm) [14,15].…”

Background: Robot-assisted laparoscopic radical prostatectomy is an advanced and popular surgical technique. However, increased intracranial pressure which is caused by CO2 pneumoperitoneum and Trendelenburg position is the main cerebrovascular effect. Measurement of optic nerve sheath diameter using ocular ultrasound is a noninvasive and reliable method for the assessment of intracranial pressure. The primary endpoint of this study was to identify whether low blood pressure regulation has any benefit in attenuating an increase of optic nerve sheath diameter during robot-assisted laparoscopic radical prostatectomy.Methods: Optic nerve sheath diameter and cerebral oxygen saturation were measured at baseline (supine position), one and two hours after pneumoperitoneum and Trendelenburg position respectively, and after return to supine position in normal (n = 27) and low blood pressure groups (n = 24).Results: Mean optic nerve sheath diameter values measured at one and two hours after pneumoperitoneum and Trendelenburg position were significantly increased compared to the baseline value (P < 0.001 in normal blood pressure group; P = 0.003 in low blood pressure group). However, the mean optic nerve sheath diameter and cerebral oxygen saturation measured at any of the time points as well as degrees of change between the two groups did not show any significant changes. The peak values of optic nerve sheath diameter in normal and low blood pressure groups demonstrated 14.9% and 9.2% increases, respectively.Conclusions: Low blood pressure group demonstrated an effect in maintaining an increase of optic nerve sheath diameter less than 10% during CO2 pneumoperitoneum and Trendelenburg position.

The efficacy of orbital ultrasonography and magnetic resonance imaging findings with direct measurement of intracranial pressure in distinguishing papilledema from pseudopapilledema

Abstract: Ophthalmological review is important to avoid unnecessary procedures for detection of true papilledema. ONS diameter is a reliable neuroimaging marker as other subtle markers.
