Scleral buckling is a common treatment modality to fix a retinal detachment. The sclera (outer white part of the eye) is buckled (indented) by sewing silicone, rubber or a semi-hard plastic band to the surface of the eye. The band applies pressure onto the sclera in the area where the retina is detached from its underlying layers. The band works by pushing the sclera towards the middle of the eye so that the torn retina lies against the wall of the eye, counterbalancing any force that pulls the retina away from its place. The band is left in place permanently and is not noticeable after the surgery.
