Optic disc elevation ultrasound
WebMar 10, 2024 · A few studies have reported that ultrasound could detect elevated optic discs ( Lochner et al., 2024 ). The optic nerve sheath is derived from the three layers of the meninges, and the pressure change in the intraorbital subarachnoid space is the same as that of the intracranial subarachnoid space. WebSep 16, 2013 · Patients with an optic disc height of 0.6 mm or less measured by sonography were unlikely to have disc swelling diagnosed by fundoscopic exam, suggesting that this may be a suitable threshold to use as an initial test for patients at risk for elevated intracranial pressure or other conditions associated with optic disc edema.
