“…Because most ultrasound probes have a smallest measurable distance of 0.1 mm, accurate measurement of ONSD with satisfactory image quality is important. Sonographic quality criteria for optimizing ONSD measurements in critical care settings have been suggested as mentioned in Ultrasound technique and the relevant anatomy of ocular sonography , and applying them in future studies may help to standardize ONSD calculations [ 16 , 48 , 49 ].…”

“…When measuring ONSD in pediatric patients (and even in infants), the maximal distensible part of the optic nerve sheath may be much more proximal than in adults. Future research should focus on the different location of ONSD with increased ICP in children [ 48 ]. Sixth, a model which could determine an accurate value of ICP by measuring the change in ONSD is needed.…”

Point-of-care ultrasound of optic nerve sheath diameter to detect intracranial pressure in neurocritically ill children - A narrative review

The rapid diagnosis of increased intracranial pressure is urgently needed for therapeutic reasons in neurocritically ill children, however this can rarely be achieved without invasive procedures. Point-of-care ultrasound of the optic nerve sheath diameter has been proposed as a non-invasive and reliable means to detect increased intracranial pressure in adults. Accordingly, clinicians may be able to use this technique to initiate early treatment and monitor the effectiveness of treatment in conjunction with other clinical examination and diagnostic modalities. Two meta-analyses and a systematic review have been published on this topic in adults. However, data on the correlation between optic nerve sheath diameter and intracranial pressure in neurocritically ill children are scarce. The aim of this review was to briefly describe what is being measured with point-of-care ultrasound of the optic nerve sheath diameter, summarize the most recent findings from adult literature, and provide an update of current work in children.

“…In the literature, the distance of 3 mm has been reported as a landmark since it is the most distensible part, provides high reproducibility and full contrast to measure the ONSD. 22 Cadaveric studies have found that a distance of 3 mm distal to the globe increases the ONSD by up to 60% contrary to a distance of 10 mm with 35%. 23 Accordingly, in studies, the ONSD measurement is performed at a distance of 3 mm.…”

Point-of-care ultrasound has been widely used by clinicians at the bedside in recent years. Various types of point-of-care ultrasound practices are employed, especially in pediatric emergency rooms and intensive care units. Pediatric intensive care specialists perform point-of-care ultrasound virtually as a part of physical examination since it provides just-in-time vital clinical information, which could assist in acute management strategies in critically ill patients. Measurement of optic nerve sheath diameter using point-of-care ultrasound is a noninvasive and radiation-free technique to determine raised intracranial pressure. Ophthalmic artery and central retinal artery Doppler indices can be used as transcranial Doppler to assess raised intracranial pressure. The aim of this review was to provide detailed information on ultrasonographic measurements of optic nerve sheath diameter and central retinal artery Doppler indices as techniques of interest for predicting increased intracranial pressure in pediatric patients in view of the literature.

“…Earlier studies have explained the TOU scanning and ONSD measuring techniques and their limitations in sufficient detail [4][5][6][7][8][9][10][11][12][13][14][15]. For this study, an investigator with less than five years of experience in radiology performed the transorbital ultrasound on GE Logiq S8 (General Electric Medical Systems, Milwaukee, WI, USA) machine using a high-resolution multi-frequency The table1 shows the comparison of ONSD according to demographics and side of measurement.…”
