Vitrectomy
Vitrectomy may be the surgical removal of the vitreous gel from the midst of a person's eye.It may be done if you find a retinal detachment, since removing the vitreous gel gives your eye doctor (ophthalmologist) better usage of the rear of the eye. The vitreous gel are often removed if blood in the vitreous gel (vitreous hemorrhage) does not yet determined on its own.
By the end of the surgery, silicone oil or a fuel is injected into a person's eye to displace the vitreous gel and restore normal pressure in the eye.
Vitrectomy is obviously done by a watch doctor who has special training in treating problems of the retina.
What To Expect After Surgery ?
Vitrectomy may require an over night hospital stay, but it might sometimes be performed as outpatient surgery. The surgery lasts 2 to 3 hours. Your eye doctor will determine if the surgery can be achieved with local or general anesthesia.
You may need to put yourself in a certain way in the home for a while. Your doctor will show you what position to lie in so that the gas or oil can push against the detachment.
Contact your doctor right away if you notice any signs of complications after surgery, such as for example:
* Decreasing vision. * Increasing pain. * Increasing redness. * Swelling around the eye. * Any discharge from the eye. * Any new floaters, flashes of light, or changes in your field of vision.
Why It Is Done ? Vitrectomy may be performed 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 due to bleeding in the vitreous gel (vitreous hemorrhage) when bleeding is severe or when the blood does not yet determined by itself after several months. * Treat severe proliferative retinopathy that triggers 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 proven to greatly improve visual acuity in lots of individuals who have severe vitreous hemorrhage that has not cleared on its own vitrectomia ivrea. A vitrectomy can decrease the danger of severe bleeding in individuals who have begun to possess bleeding in to the vitreous gel. It can also reduce the danger of severe bleeding in individuals with growth of abnormal blood vessels in the iris.
Generally speaking, surgery can restore some vision lost as a result of traction retinal detachment and can help prevent further detachment. But the outcomes are generally better when the detachment has not affected the center of the retina (macula) and the central vision it provides.
Risks
Vitrectomy may cause elevated pressure inside a person's eye (intraocular pressure, or IOP), especially in individuals who have glaucoma.
There are many other serious, vision-threatening risks associated with vitrectomy. These include:
* Further bleeding in to the vitreous gel. * Retinal detachment. * Fluid buildup in the clear covering of a person's eye (corneal edema). * Infection inside a person's eye (endophthalmitis).
