The reduction of this nerve circulation can cause persistent symptoms after surgery using the Smith-Petersen approach even if direct trauma to the nerve is avoided.
Right frame: late-phase fluorescein angiography shows minimal retrograde filling from the optic nerve circulation of the retinal vasculature with late intraretinal staining around the optic nerve.
Numerous glaucoma studies have demonstrated that optic nerve damage depends on IOP, but optic nerve circulation, age, race, genetics and other factors are also critical.
While the flow of blood through major vessels is under the control of the nerves, circulation through the capillary beds is of a more primitive type and is under the influence of local metabolic products.
Some authors suggested that physiological nocturnal hypotension, in the presence of other vascular risk factors, can bring the optic nerve head circulation under the critical levels and thus play a role in the pathogenesis of anterior ischemic neuropathy and glaucoma [ 1, 10, 16, 28].
Its effect is "a mood of fullness, plenitude, or liveliness, a sense of having had one's nerves or circulation or concentration powers tuned up or recharged a shot in the arm, a fleeting return to childlike excitement about life".
The main causes of ulcers are infection, faulty blood circulation, nerve damage, trauma, nutritional disturbances including thiamine or other vitamin deficiencies, and cancer.
The checks are important for diabetics because those who end up with dangerously high blood-glucose levels can suffer nerve damage, poor circulation and reduced feeling in their feet and legs.
To study the effects of trabeculectomy and needling revision of poorly functioning blebs on the optic nerve head (ONH) circulation in patients with primary open-angle glaucoma (POAG).
Controlled animal experiments demonstrate that ultrafine particulate matter (PM), a component of traffic-related air pollution, can translocate to the brain via the olfactory nerve or systemic circulation (Elder et al. 2006; Oberdörster et al. 2004; Peters et al. 2006), where it may promote CNS dysfunction.
Any solution which relieves pressure on the nerve and promotes circulation in the microvascular neural blood supply is likely to "cure" Carpal Tunnel Syndrome and relieve its attendant symptoms of pain, etc.
