Optic nerve sheath decompression for the treatment of visual failure in chronic raised intracranial pressure.

Optic nerve sheath decompression for the treatment of visual failure in chronic raised intracranial pressure.

The records of all patients undergoing optic nerve sheath decompression for visual failure in chronic raised intracranial pressure performed over a 15 year period have been reviewed. The aim was to study the visual outcome and relation to any shunting procedures. Fourteen patients (20 eyes) were identified in whom follow up information of at least one year was available. Eleven patients had ben...

Optic nerve ultrasound for the detection of raised intracranial pressure.

BACKGROUND Optic nerve ultrasonography (ONUS) may help identify raised intracranial pressure (ICP). The optimal optic nerve sheath diameter (ONSD) cut-off for the identification of intracranial hypertension has not been established, with some clinical studies suggesting a higher cut-off than may be expected on the basis of prior laboratory investigation. OBJECTIVE To validate ONUS performed b...

Efficacy and safety of optic nerve sheath fenestration in patients with raised intracranial pressure

OBJECTIVE To evaluate the efficacy and safety of Optic Nerve Sheath Fenestration (ONSF) in patients with raised intracranial pressure (ICP). METHODS This Quasi Experimental Study was conducted at Armed Forces Institute of Ophthalmology, Rawalpindi from July 2013 to July 2015. Thirty one eyes of 18 patients who underwent ONSF for raised ICP were followed up for one year to ascertain efficacy a...

Optic nerve ischemia: optic nerve sheath decompression alone or with optic nerve decompression.

Brain Trauma Measurement of Optic Nerve Sheath Diameter for the Assessment of Risk of Raised Intracranial Pressure

Raised intracranial pressure (ICP) is associated with poor outcome after brain injury, but is difficult to detect without invasive devices. As a part of the central nervous system, the optic nerve is surrounded by a dural sheath, and the subarachnoid space surrounding the optic nerve is subject to the same pressure changes as the intracranial compartment. Distension of the optic nerve sheath re...
