Scleral Buckle is a surgical procedure used to repair a retinal detachment. Retinal detachments are usually caused by retinal tears, and a scleral buckle can be used to close the retinal break, both for acute and chronic retinal detachments. The sclera, or the white of the eye, is the outer supporting layer of the eyeball. In this surgery, your retina surgeon attaches a piece of silicone or a sponge onto the white of the eye at the spot of a retinal tear. The buckle is designed to repair retinal detachment by pushing the sclera toward the retinal tear or break. Sometimes, the retina doesn’t completely detach from the eye, but instead forms a tear. Scleral buckling can sometimes be used to repair retinal tears, which can prevent retinal detachment. Scleral buckling is used to treat different types of retinal detachments. Retinal detachment surgery usually also involves the use of cryotherapy or laser photocoagulation. The laser or cryotherapy forms a permanent adhesion around the retinal break and prevents further accumulation of fluid and re-detachment. Retinal detachment is a medical emergency requiring immediate medical care. If left untreated, retinal detachment can cause permanent loss of vision.
