“…First, while ONSD has yet to be validated by further imaging modalities such as MRI, previous studies have reported good agreement. Second, although our sample size was quite small, our data groupings were consistent with studies that created normative data for children [3]. However, at this point our data should not be considered as normative, as further research is absolutely necessary.…”

“…In patients at risk for raised ICP, invasive monitoring can be utilized but harmful side effects have been reported [1-3]. For this reason, measurement of the optic nerve sheath diameter (ONSD) through ultrasonography has been established as a safe, noninvasive alternative [1, 3-8]. Briefly, pressure variations within the chiasmal cistern are transmitted to the subarachnoid space surrounding the optic nerve, directly influencing the ONSD [9].…”

“…When the ICP is increased, the ONSD also increases [1, 4]. Ultrasonography of the ONSD has been documented in several different pediatric populations at risk for raised ICP including: diabetic ketoacidosis [5, 10], craniosynostosis [6], hydrocephalus [7, 11], ventriculoperitoneal shunts [3, 8], metabolic disorders (hepatic failure) [12, 13], suspected intracranial lesions (traumatic brain injury and nontraumatic brain injury) [9, 10, 13, 14], hypoxic injury [13], intracranial hemorrhage [11, 13], infection [11, 14], meningoceles [11], and spina bifida.…”

Optic Nerve Sheath Diameter for Preterm Infants: A Pilot Study

Objective: In preterm infants, early diagnosis and management of a raised intracranial pressure (ICP) may be important to improve neurodevelopmental outcomes. While invasive ICP monitoring is not recommended, ultrasonography of the optic nerve sheath diameter (ONSD) could provide a noninvasive alternative to evaluate ICP. The objective of this pilot study was to document ranges of ONSD in preterm infants. Methods: This prospective cohort pilot evaluated preterm infants who were admitted to the neonatal intensive care unit without suspected raised ICP. Three images per eye were obtained from a 20–5 MHz linear array ultrasound transducer placed on the patient’s superior eyelid. The OSND was measured 3 mm behind the globe. A second ultrasonographer duplicated half of the scans. Multiple linear regression analysis was conducted for both right and left ONSD with corrected gestational age, weight, and head circumference as predictors. Lin’s concordance assessed interrater reliability. Results: In 12 preterm infants 114 scans were performed on both eyes. The median age was 33 weeks (corrected gestational age) with a range of 29–36 weeks. Corrected gestational age was the strongest predictor for ONSD, and preliminary measurements at each gestational age were established. Interrater reliability demonstrated substantial agreement (Q_c = 0.97). Conclusion: In preterm infants, ONSD strongly correlates with corrected gestational age. These data should be validated with other imaging modalities before abnormal ranges can be considered.

“…This was in agreement with our work. In a study conducted by Ballantyne et al [21] to determine normal optic nerve sheath in normal children, they observed a progressive increase in optic nerve diameter with increasing age. There was a significant positive correlation between ONSD and age established from their study.…”

Background: Raised intracranial pressure (ICP) is a common manifestation of severe brain injury and measurement of optic nerve diameter using ultrasound as a non-invasive method is increasing being use as a marker to detect raised ICP. The aim of this study is to determine normal optic nerve sheath diameter in normal Nigerian adults. Methods: This was a cross-sectional prospective study conducted at the radiology department on 150 normal adults over a period of ten months. The optic nerve sheath diameter (ONSD) was measured 3mm behind the globe using 7.5 MHz linear probe placed over the closed eyelid with subjects in supine position. Results: The mean age of the studied population was 38.69±12.

Hemodynamic Interactions in the Eye: A Review

2012

View full text Add to dashboard Cite

The ocular circulation provides readily visible information about the state of the systemic circulation, as well as being potentially of relevance to the pathogenesis of ocular disorders such as glaucoma. The interaction between intraocular pressure, retinal vessels and cerebrospinal fluid pressure located at the retrolaminar portion of the eye has been of great interest for both ophthalmic and neurological clinicians and researchers. Understanding the relationship between these physiological parameters can explain phenomena such as spontaneous retinal venous pulsatility, and characterize the effects of the translaminar pressure gradient. It may be feasible to use measurable changes in venous pulsatility to enhance clinical assessment in different diseases. In this article we review recent findings on ocular hemodynamics and the relevance of these parameters in the diagnosis of ophthalmic and neurological diseases.
