Ablasio retina is more likely to occur in people who suffer from low vision far (myopia) and on the people who are members of his family who have experienced ablasio the retina. Ablasio retina can also be caused by other eye diseases, such as tumors, inflammation is excellent, due to trauma or as a complication of diabetes. When not immediately carried out the actions, ablasio of the retina can cause defective vision or blindness are settled. The retina is a thin and transparent network that is sensitive to light, which is made up of cells and nerve fibers. The retina of the eye wall of the inside lining, function like a movie on a photo-camera, the light through the lens will be focused onto the retina. The cells of the retina that is sensitive to this light capturing pictures and channel it to the brain via the optic nerve.
The cause of
Most of the ablasio retina occur due to one or more of the RIP-rips or holes in the retina, known as the ablasio retina regmatogen (Rhegmatogenous Retinal Detachment). Sometimes a normal aging process can cause the retina to become thinner and less healthy, but more often lead to damage and tear in the retina is the shrinking of the corpus vitreum, clear material like agar that fills the middle part of the eyeball.
Corpus vitreum cling tightly at some locations. When corpus vitreum shrinks, he can withdraw a portion of the retina in place attached, giving rise to a tear or hole in the retina. Some types of corpus vitreum shrinkage is normal thing happened on seniors and usually do not cause damage to the retina.
Corpus vitreum may also shrink at the grows into eyeballs of once (sometimes this is a result of shortsighted away), by inflammation, or due to trauma. In most cases the retina loose after a new major changes to the structure of corpus vitreum.
If there is already a tear-tear of the retina, the liquid from the corpus vitreum may go into a hole in the retina and can flow between the sensory layer of the retina and the retinal pigment epithelium. This fluid will fill the gap in the potential between the two layers of the retina resulting in loose.
The retina detached will not function properly and in this area arise blurred vision or blind areas. Another form of ablasio retinal ablasio retina i.e. traction (Traction Retinal Detachment) and retinal ablasio eksudatif (Exudative Retinal Detachment) generally occurs secondary to another disease.
Ablasio retina traction caused by scar tissue (fibrosis) that attaches to the retina. Contraction of scar tissue that can pull the retina so that happens ablasio the retina. Ablasio retina eksudatif may occur due to damage to the retinal pigment epithelium (in normal circumstances serves as the outer barrier), due to an increase in the permeability of the wall of blood vessels by various causes or stockpiling of fluid that occurs in the process of inflammation.
Symptoms
The symptoms often complain about the patient are:
- Floaters (visibility of objects hovering). that happened because of the turbidity in vitreus by blood, loose or retinal pigment degeneration vitreus itself.
- Photopsia/Light flashes (flashing lights). in the absence of the surrounding light sources, which generally occurs when the eye is driven in this light or in a State of darkness.
- A sharp decline of vision. sufferers complain of vision partially like a curtain covered the longer more extensive. On the circumstances that have been advanced, it can happen to a sharp fall in the weight of the vision.
Diagnosis is based from the existing symptoms and the results of an examination of the eye. The loss of the retina can usually be viewed using oftalmoskop. If the retina is detached is not visible, then it can be assisted by ultrasound examination of the eyes to identify them.
Treatment
Engineering operations various kinds, depending on the extent of the retinal layers off and damage occurred, but all designed to hold the wall of the eye to the hole, hold the retina so that both networks were still clinging to scar tissue formed and attach again rips. Sometimes the fluid must be removed from under the retina to allow the retina attached back to the back wall of the eye.
Often a silicone or tape bearing the suppressor is placed on the outer wall of the eye to gently hit the back wall of the eye to the retina. This is also done in the operation of the Act to create scar tissue that will aggravate the tear of the retina, for example by freezing, laser or with heat diatermi (power inserted with a needle).
On a more complicated retinal ablasio may take a vitrectomy techniques. In this operation the corpus vitreum and connective tissue in the retina wrinkle removed from eyes. In some cases when the retina itself is very wrinkled and shrunk the retina may have to be pushed to the wall of the eye for a while by filling the cavity which contains the used corpus vitreum with air, gas or silicone oil. More than 90% of the loss of the retina can be glued together again with the techniques of modern eye surgery, although sometimes needed more and a one-time operation.
When the retina is successfully transferring back the eye will regain some functions of sight and total blindness can be prevented. But how far the vision can be restored within six months after the Act's operation depends on a number of factors. In general the function of vision will be less recovered when ablasio the retina has been going on long enough or appear on the surface of the retina tissue growth.
Corpus vitreum continues to shrink and the emergence of tissue growth on the surface of the retina causing not all retina detached can be glued together again. If the retina cannot be glued together again, then the eye vision will continue to decline and eventually become blind.
Prevention
- Use the visor to prevent the occurrence of trauma on
- Diabetics control their blood sugar levels should be
- If you have the risk of suffering retinal ablasio, check with your
- eyes at least once a year.
