![]() ![]() The development of scar tissue membranes has a poor prognosis and patients require additional surgical procedures, including vitrectomy (removal of the vitreous gel), membrane peeling and retinal reattachment. This growth, or proliferation of scar tissue is known as Proliferative Vitreo-Retinopathy (PVR). In about 10% of patients scar tissue grows along the surface, within, or beneath the retina, causing the retina to detach. New or recurrent retinal detachments can arise because of new retinal breaks or persistent pulling by the vitreous gel on the retina. If the retinal detachment involves the macula, there may be irreversible loss or only partial recovery of vision, so the extent of visual improvement following surgery cannot be predicted preoperatively. If the macula was still attached before surgery, chances for good vision after surgery are very good. The macula is the central portion of the retina and is responsible for reading vision. Subretinal fluid is sometimes externally drained from the eye, and occasionally, sterile gas is injected into the eye to help hold the retina in position. This silicone piece causes indentation of the eye wall against the retinal breaks, which closes the retinal breaks and releases the inner traction caused by the vitreous. A solid silicone rubber band or piece is then sutured to the tough, white coat of the eye (the sclera). Liquid vitreous can flow through the breaks, and under the retina, causing separation from the eye wall causing a retinal detachment.ĭuring scleral buckle procedure, the retinal breaks are identified and treated with cryotherapy and/or laser. This results in a vitreous separation (vitreous detachment), which can be associated with traction and retinal breaks. The vitreous gel is firmly adherent to most of the retina at birth, but naturally liquefies over the years and shrinks away from the retina. The vitreous cavity contains a jelly-like substance called the vitreous gel. The retina is the light sensitive layer which lines the back 2/3 of the eye. Or a combination of these techniques remains at the discretion of your retinal specialist.Scleral Buckle Surgery is one of the techniques used for retinal detachment repair. The decision to treat retinal detachment with using a scleral buckle, vitrectomy, pneumatic retinopexy, Retinal detachments are treated on a case-by-case basis for every patient.
