Scleral buckle
Scleral Buckle
Scleral buckle (pronounced: skleer-uhl buhk-uhl) is a surgical procedure primarily used to repair a retinal detachment. The term originates from the words 'sclera', which is the white outer layer of the eyeball, and 'buckle', which refers to the object placed to indent the wall of the eye.
Procedure
During a scleral buckle procedure, a piece of silicone or sponge is sewn onto the sclera at the site of the retinal tear. The buckle acts to indent the wall of the eye, relieving the traction (pull) on the retina, and allowing the retinal tear to settle against the wall of the eye. The buckle remains on the eye indefinitely.
Indications
Scleral buckle is indicated for rhegmatogenous retinal detachment, a type of retinal detachment that occurs when fluid seeps through a retinal tear, causing the retina to separate from the underlying tissues.
Risks and Complications
Like any surgical procedure, scleral buckle surgery carries potential risks and complications. These may include infection, bleeding, high or low eye pressure, cataract, double vision, and re-detachment of the retina.
