The optic nerve can be damaged when exposed to direct or indirect injury. Direct optic nerve injuries are caused by trauma to the head or orbit that crosses normal tissue planes and disrupts the anatomy and function of the optic nerve; e.g., a bullet or forceps that physically injures the optic nerve.
The anterior optic nerve receives blood primarily from the posterior ciliary arteries. The anterior optic nerve, a.k.a. the optic nerve head, is surrounded by the scleral canal, and is vulnerable to crowding of nerve fibers. The portion of the optic nerve head that is visible by looking into the eye with an ophthalmoscope is called the optic disc.
The exact mechanism of optic nerve ischemia in these cases remains unclear, but contributing factors may include hypotension, anemia, hypoxia, and changes in the autoregulation of optic nerve arterial blood flow. The incidence of ischemic optic neuropathy leading to vision loss following general surgeries ranges between 0.1% and 0.002%.
This loss results in hindbrain herniation and causes major compression of the upper cervical spinal cord. The quadriplegia dissipates once the patient lies supine. [59] An extremely rare complication of sCSFL is third nerve palsy, where the ability to move one's eyes becomes difficult and interrupted due to compression of the third cranial ...
The symptoms of nerve injury in the early 1900s were called nerve palsy (today neuropathy or neuritis are more common terms). [50] The concept of injuries causing nerve palsy was understood at that time. [49] For example, wrist fractures were known to be a cause of nerve palsy through compression, and this could be treated by liberating the nerve.
The optic nerve is the bundle of axons that carry the visual signals from the eye to the brain. This optic nerve must penetrate through the wall of the eye, and the hole to accommodate this is usually 20-30% larger than the nerve diameter. In some patients the optic nerve is nearly as large as the opening in the back of the eye, and the optic ...
The thickened and enhanced symptomatic nerve, as shown in recent MRI findings, might be indicative of the existence of structural nerve damage in RPON. [12] Therefore, neuropathy is suggested as the primary cause of RPON, [ 21 ] either induced by recurrent viral infections or immune-mediated inflammation . [ 22 ]
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
