Effect of Tonsillar Retractor on Intracranial and Intraocular Pressure in Children Undergoing Adenotonsillectomy Surgeries

Laryngoscope Investigative Otolaryngology, Volume 11, Issue 2, April 2026.
The effect of tonsillar retractor placement on IOP and ONSD values. ABSTRACT Objectives The tonsillar retractor used during adenotonsillectomy, one of the most common pediatric surgeries, may increase sympathetic activity. This study aimed to evaluate the effect of tonsillar retractor insertion on intracranial pressure (ICP) and intraocular pressure ...

Ultrasonic optic disc height combined with the optic nerve sheath diameter as a promising non-invasive marker of elevated intracranial pressure

Frontiers in Physiology, 2023
Background/aim: Patients with elevated intracranial pressure (ICP) tend to have optic disc edema and a thicker optic nerve sheath diameter (ONSD). However, the cut-off value of the optic disc height (ODH) for evaluating elevated ICP is not clear.

Ultrasound in Women's Health: Mechanisms, Applications, and Emerging Opportunities

Advanced Materials, Volume 38, Issue 14, 6 March 2026.
As healthcare moves toward decentralization, ultrasound technologies are evolving from strictly imaging tools in clinical settings into versatile diagnostic and therapeutic platforms, with growing roles addressing women's health needs. This review highlights how ultrasound's underlying physical mechanisms can be harnessed to reduce disparities in women'

Comparative analysis of intracranial pressure prediction models using optic nerve sheath diameter and additional ultrasound metrics

Scientific Reports
Optic nerve sheath diameter (ONSD) assessment of elevated intracranial pressure is increasingly emphasised as a noninvasive modality. Nevertheless, quantitative assessment remains limited, and study criteria vary.

Effects of Age and Sex on Optic Nerve Sheath Diameter in Healthy Volunteers and Patients With Traumatic Brain Injury

Frontiers in Neurology, 2020
The measurement of optic nerve sheath diameter (ONSD) has been reported as a non-invasive marker for intracranial pressure (ICP). Nevertheless, it is uncertain whether possible ONSD differences occur with age and sex in healthy and brain-injured ...

Surgical Interventions in Idiopathic Intracranial Hypertension—A Comprehensive Multi‐Center Study of Outcome and the Role of Treatment Indication

European Journal of Neurology, Volume 33, Issue 3, March 2026.
In this multicenter retrospective study of idiopathic intracranial hypertension, only 3.6% of patients required surgery, predominantly for acute visual deterioration. Both cerebrospinal fluid diversion and optic nerve sheath fenestration were effective in improving visual outcomes and resolving papilledema, while headache improvement was limited ...
