Retrobulbar neuritis, an inflamed optic nerve, but with a normal-appearing nerve head, is associated with pain and the other findings of papillitis. Pseudopapilledema is a normal variant of the optic disk , in which the disk appears elevated, with indistinct margins and a normal vascular pattern.
It is also known as optic papillitis (when the head of the optic nerve is involved), neuroretinitis (when there is a combined involvement of the optic disc and surrounding retina in the macular area) and retrobulbar neuritis (when the posterior part of the nerve is involved).
Diabetic papillopathy (also known as diabetic papillitis) is an ocular complication of diabetes mellitus characterized by optic disc swelling and edema of optic nerve head. The condition may affect both type 1 and type 2 diabetic patients.
Of those participants, seven developed a condition called non-arteritic ischemic anterior optic neuropathy (NAOIN, which is sudden vision loss due to lack of blood flow to the optic nerve, and is ...
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 American study found that Ozempic more than doubles the risk of non-arteritic anterior ischemic optic neuropathy (NAION), a rare condition that damages the optic nerve.
However, the anterior end of the optic nerve stops abruptly at the eye. Hence the pressure is asymmetrical and this causes a pinching and protrusion of the optic nerve at its head. The fibers of the retinal ganglion cells of the optic disc become engorged and bulge anteriorly. Persistent and extensive optic nerve head swelling, or optic disc ...
Uncontrolled blood glucose (sugar) can lead to complications that may include cardiovascular disease, high blood pressure, nerve and eye damage, and kidney disease.
