When tear retina, but not out, then the release of retina that can be prevented by immediate action. When the retina has separated, the retina must be repaired with surgery by the ophthalmologist. Successful re-attachment retina, consisting of attachment of retinal tears and prevent the retina not separated anymore. There are several surgical procedures that can be used. The procedures selected depend on the severity of retinal detachments and physician judgment.
Laser photocoagulation: If found small tears in the retina with little or no loss of retina, the tear can be glued together again with laser.Laser light-burns will place small burns around the edge of tears. This burn will cause scar tissue that binds to the edge of the tear and prevent fluid passing and gathered under the retina. Ophthalmology laser surgery is now usually performed as an act of ambulatory patients and do not require surgical incisions.
Freezing: Freeze the back of the wall of the eye that lies behind the retina tears, it can stimulate the formation of scar tissue and taping edge of the retinal tears with the back wall of the eyeball. Establishment procedure is usually performed with ambulatory patients, but requires local anesthesia on the eye.
Surgical procedures. If enough fluid that had accumulated under the retina and separates the retina to the back of the eye will require a more complicated surgery to treat the retina loose. The technique of operation vary, depending on the extent of retina layers are separated and the damage, but all designed to suppress the wall of the eye to the retina hole, holding that the two networks that remain attached to the scar tissue attach more tears. Sometimes the fluid must be removed from the retina to allow the retina back against the back wall of the eye. Often a silicone band or pressure pad in place on the outside of the eye to gently push the back wall of the eye to the retina. Within doing all these operations in action to create scar tissue that will taping torn retina, for example by freezing, by laser or diathermy heat (electricity included with a needle).
On a more complicated retinal detachments may be in need of a technique called vitrektomi. In this surgery the corpus vitreum is released from the fibers of the connective tissue in the retina, and the shrinking of the corpus vitreum in out of the eye. In some cases if the retina itself is very wrinkled and shrunk the retina may be pushed to the wall of the eye for a while to fill the cavity that was once the corpus vitreum by air or gas.
More than 90% loss of retina can be reattached with the techniques of modern eye surgery. Sometimes it takes more than one operation.
