Scleral buckle is a treatment procedure to repair a detached retina. It involves securing a thin band of silicone around the sclera, the white part of your eye. Buckles are placed to create a dimple. The procedure moves the tissues in the eye closer together and releases fluid under the retina, causing the retina to reattach. Scleral buckles are performed with local or general anesthesia. They are most frequently performed as outpatient procedures.
