Repair of Detached Retina, Scleral Bucking The physician explores the sclera to locate the site overlying a retinal detachment. Stay sutures are used on the rectus muscles so the eye may be exposed to the area that will be treated. The physician treats the retinal tear externally, by placing a cold probe over the scleral and depressing it. This seals the choroid to the retina at the site of the tear. The physician cuts a groove in the sclera and sutures are places across this incision. Any subretinal fluid is drained. A Silastic band is laid in the scleral bed and sutured in place. Sometimes, a silicone patch is placed under the band. When the tear has been adequately repaired and supported, the rectus muscle sutures are removed.
