Will Posterior vitreous detachment heal on its own?
Just sustained an eye injury and was told the answer was no! Sorry
What is hypermyopia?
Extreme short sightedness Hypermyopia is Retinal Detachment The retina is attached to the sclera in the back of the eye, and a retinal detachment occurs when it is pulled away from this normal position. The retina, like film in a camera, is responsible for creating the images that one sees. A good picture could not be produced if the film were not in its correct location within the camera, and we lose vision if the retina is not in its proper place within the eye. The retina detaches by separating from the back wall of the eye. When it is removed from its blood supply (the choroid), it will lose nourishment and result in a loss of some vision if not repaired in time. This retinal tear may be caused by trauma or by a vitreous detachment (or "posterior vitreous detachment"). Vitreous detachment, not uncommon in older people, results from the vitreous fluid shrinking and pulling away from the retina. This causes "floaters," which do not damage the retina or vision.

What is the purpose of vitrectomy surgery?
A vitrectomy is a surgery performed on the eye. This surgery removes the gel of the eye known as the vitreous humor. It is used to aid in the treatment of eye conditions such as vitreous floaters and retinal detachment.
What disease correspond to the code 379.21?
* Detachment of the corpus vitreum (VITREOUS BODY) from its normal attachments, especially the retina, due to shrinkage from degenerative or inflammatory conditions, trauma, myopia, or senility. * 379.21 is a specific code that can be used to specify a diagnosis * 379.21 contains 6 index entries * View the ICD-9-CM Volume 1 379.* hierarchy * Vitreous: ** cavitation ** detachment ** liquefaction 379.21 refers to vitreous detachment/cavitation/degeneration. Information source: first hand from my trusted opthalmologist.
When is vitrectomy performed for retinal detachment?
Vitrectomy is typically performed in more complex cases of retinal detachment. During the procedure, the vitreous gel is removed, and the retina is reattached with the help of gas or silicone oil.
What can be done for Vitreous Hemmorhage?
See a retina specialist to be sure that there are no retinal tears or detachment. If there are none, wait for blood to be re-absorbed. If situation doesn't clear up soon, revisit the retina specialist.
Gel-like substance that helps to reinforce the eyeball?
It is called the vitreous humor. The word humor here has nothing to do with comedy. The word can mean 'body fluid', from the Latin for body fluid, 'umor'.
What is the procedure to repair a detached retina?
The vitreous is a gel-like fluid which fills most of the eye. As people age, this vitreous becomes more and more liquefied. The vitreous has loose attachments to the retina, and more firm attachments to the optic nerve. At some point in a person's life, the vitreous liquefies enough to shift position in the eye. When this occurs, usually between age 50 and 70, the back edge of the vitreous will pull forward away from the retina, leading to a "vitreous detachment". This is generally a normal process, although it may happen abnormally early in cases of high nearsightedness or trauma. As the vitreous detaches, it tugs on the retina. This is perceived as a flash of light, similar to a lightning flash in the corner of the vision. It may occur especially with eye movement, since the vitreous moves in the eye. Debris pulled off of the optic nerve and retina are then seen as floaters, suspended in the vitreous above the retina. Sometimes this is described as a cobweb, a net, a string, or a fly over the vision.
What is calcite luster?
Vitreous. Otherwise, no.
Is there a scientific word for detached retina?
"Retinal detachment" is the usual medical term. The condition is most commonly due to a tear in the retina especially in people who are short sighted (myopic). This is a technically a rhegmatogenous retinal detachment. The rip allows fluid from the vitreous cavity to pass beneath the retina so the retina progressively separates from the retinal pigment epithelium beneath. Ultimately the entire retina can detach called a total detachment. This is sometimes also called a "funnel detachment" because the retina remains attached to the optic nerve at the back of the eye. There are other types such as "tractional retinal detachment" in patients with severe diabetic eye disease or "exudative detachments" due to inflammatory conditions.
What does it mean when you see floaters in your eyes?
In an older person Posterior Vitreous Detachment. In middle age the Vitreous Gel inside the eye begins to degenerate and shrink, which can cause a separation of the vitreous gel from the retina at the back of the eye. This normal ageing condition leads to "floaters" or "spiders" in the field of vision. Associated with the condition are flashes of light in the dark. Your vision is otherwise not affected. There is very little, other than wearing dark glasses, that can be done.
