A surgical nerve decompression can relieve pressure on the nerve but cannot always reverse the physiological changes that occurred before treatment. (wikipedia.org)
Surgical decompression is indicated when mechanical compression is suspected. (publisso.de)
Optic nerve decompression surgery (also known as optic nerve sheath decompression surgery) involves cutting slits or a window in the optic nerve sheath to allow cerebrospinal fluid to escape, thereby reducing the pressure around the optic nerve. (aetna.com)
Initial results of uncontrolled studies suggested that optic nerve sheath decompression was a promising treatment of progressive visual loss in patients with NAION. (aetna.com)
To resolve the controversy over the effectiveness of optic nerve decompression for NAION, the National Eye Institute sponsored the Ischemic Optic Neuropathy Decompression Trial, a multicenter, randomized controlled clinical trial of optic nerve decompression surgery for patients with NAION. (aetna.com)
The investigators concluded that optic nerve decompression surgery is not an effective treatment for NAION, and in fact, may increase the risk of progressive visual loss in NAION patients. (aetna.com)
A structured evidence review (Dickersin and Manheimer, 2002) concluded that "[r]esults from the Ischemic Optic Neuropathy Decompression Trial indicate that optic nerve decompression surgery for nonarteritic ischemic optic neuropathy is not effective. (aetna.com)
A Cochrane review (Dickersin et al, 2012) concluded that results from the single trial indicate no evidence of a beneficial effect of optic nerve decompression surgery for NAION. (aetna.com)
The use of surgical decompression for treating nerve compression due to the loop in the internal auditory canal is not always accepted due to the risk related to the surgical procedure. (alliedacademies.org)

Just beyond the end of the carpal ligament, the median nerve trifurcates to become the common digital sensory nerves to the fingers. (medscape.com)
The sensory nerves are also called afferent nerves because they originate in the peripheral body, travel to the spinal column, and terminate in the brain where the electrical signal is perceived and interpreted. (drdanielandersonblog.com)
