Most retinal detachments are treated with a technique known as <u>scleral banding</u>, which involves placing a silicone band over the detached area, forcing the layers of the retina together.
What is scleral banding or buckle?
A scleral buckle is one of several ophthalmologic procedures that can be 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.
Scleral buckles come in many shapes and sizes. A silicone sponge (with air filled cells) is a cylindrical element that comes in various sizes. An encircling band is a thin silicone band sewn around the circumference of the sclera of the eye. A solid silicone grooved Tyre element is also used. Buckles are often placed under a band to create a dimple on the eye wall.
