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 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%.
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 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.
In one study, optic nerve sheath hemorrhage was present in all 13 infants with non-accidental intracranial injury, and multilayered retinal hemorrhage was present in at least one eye of 11 of the 13 infants. [21] Hyphema is a complication that can occur after glaucoma filtering surgery, although the causes are not always well known.
Carpal tunnel surgery is usually considered after other treatment options have failed, Melamed says. Other, less invasive treatments, like splinting and steroid injections, are typically tried first.
Optic neuritis is an inflammation that damages the optic nerve. It’s linked to multiple sclerosis (MS). Along with flickering or flashing with eye movement, symptoms include pain, loss of colour perception, and vision loss.
