Vitrectomy
Vitrectomy may be the surgical removal of the vitreous gel from the middle of the eye.It may be done if you have a retinal detachment, since removing the vitreous gel gives your eye doctor (ophthalmologist) better usage of the trunk of the eye. The vitreous gel may also be removed if blood in the vitreous gel (vitreous hemorrhage) does not clear on its own.
At the end of the surgery, silicone oil or a fuel is injected into the eye to restore the vitreous gel and restore normal pressure in the eye.
Vitrectomy is obviously done by an eye doctor who has special training in treating problems of the retina.
What To Expect After Surgery ?
Vitrectomy may require an overnight hospital stay, but it might sometimes be achieved as outpatient surgery vitrectomia italia . The surgery lasts 2 to 3 hours. Your eye doctor will determine if the surgery can be done with local or general anesthesia.
You will need to position yourself in a certain way at home for a while. Your doctor will tell you what position to lie in so the gas or oil can push from the detachment.
Contact your doctor straight away if you see any signs of complications after surgery, such as:
* Decreasing vision.
* Increasing pain.
* Increasing redness.
* Swelling round the eye.
* Any discharge from the eye.

Why It Is Done ? Vitrectomy may be achieved to
* Repair or prevent traction retinal detachment, especially when it threatens to affect the macula.
* Repair very large tears in the retina.
* Reduce vision loss caused by bleeding in the vitreous gel (vitreous hemorrhage) when bleeding is severe or when the blood does not clear by itself after several months.
* Treat severe proliferative retinopathy that produces severe scar tissue formation or when growth of new blood vessels on the retina (neovascularization) continues despite repeated laser treatment.
How Well It Works ?
Vitrectomy has been demonstrated to greatly improve visual acuity in lots of people who have severe vitreous hemorrhage that's not cleared on its own. A vitrectomy can decrease the risk of severe bleeding in people who have begun to own bleeding to the vitreous gel. Additionally it may reduce the risk of severe bleeding in people who have growth of abnormal blood vessels in the iris.
Generally, surgery can restore some vision lost as a result of traction retinal detachment and might help prevent further detachment. But the results are generally better when the detachment has not affected the biggest market of the retina (macula) and the central vision it provides.
Risks
Vitrectomy may cause elevated pressure inside the eye (intraocular pressure, or IOP), especially in people who have glaucoma.
There are numerous other serious, vision-threatening risks related to vitrectomy. These generally include:
* Further bleeding to the vitreous gel.
* Retinal detachment.
* Fluid buildup in the clear covering of the eye (corneal edema).
* Infection inside the eye (endophthalmitis).
