Objective: we aimed to evaluate the utility of transorbital ultrasonography (TOS) in optic nerve assessment and quantification of ON atrophy in MS patients, and to determine whether ON atrophy correlates with the disease duration and disability measured on the Kurtzke Expanded Disability Status Scale (EDSS).
Materials And Methods: Prospective, multicentre, blinded cohort study of 59 patients diagnosed with relapsing-remitting MS and 36 controls.
Results: When measured with TOS, the diameter of both the right (2.69 ± 0.30 mm in cases; 3.20 ± 0.19 mm in controls, P < .0001) and left (2.71 ± 0.26 mm in cases; 3.24 ± 0.15 mm controls, P < .0001) ON of study patients was smaller than controls. We observed a negative correlation between EDSS and both right (ρ = .524) and left (ρ = .469) ON diameter. We also observed a negative correlation between disease duration and both right (r = .602) and left (r = .538) ON diameter. No difference was observed in the diameter of both ON among patients with a history of optic neuritis (right OND 2.68 ± 0.29 mm; left OND 2.69 ± 0.25 mm) and patients with no history of optic neuritis (right OND 2.70 ± 0.30 mm; left OND 2.73 ± 0.27 mm) (P = .805; P = .651).
Conclusions: The thickness of ON measured with TOS is correlated with EDSS and the duration of the disease without being interfered by the previous history of optic neuritis. TOS could be a reliable technique for measuring ON atrophy in MS.

The most common diagnostic error of IIH is inaccurate funduscopic examination. Moreover, IIH could be diagnosed without papilledema. Trans orbital sonography could be used as a non-invasive and cheap tool for discovering increased ICP (intracranial Pressure).

Objective: Targeted mild hypercapnia is a potential neuroprotective therapy after cardiac arrest. In this exploratory observational study, we aimed to explore the effects of targeted mild hypercapnia on cerebral microvascular resistance assessed by middle cerebral artery pulsatility index (MCA PI) and intracranial pressure estimated by optic nerve sheath diameter (ONSD) in resuscitated out-of-hospital cardiac arrest (OHCA) patients.
Design Setting Participants And Interventions: Comatose adults resuscitated from OHCA were randomly allocated to targeted mild hypercapnia (PaCO 50-55 mmHg) or targeted normocapnia (PaCO 35-45 mmHg) for 24 h in the TAME trial.
