ⓘ Scleral 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.

Sclera buckles come in many shapes and sizes. Silicone sponge with air-filled cells is a cylindrical element that comes in different sizes. Surrounding strip of thin silicone band sewn around the circumference of the sclera of the eye. Solid silicone grooved tyres, the element is also used. Buckles are often placed in groups to create dimples on the wall of the eye.

The scleral buckle is secured around the eye under the conjunctiva. This moves the wall of the eye closer to the detached retina. This change in the relationships of the tissues seems to allow the liquid, which is formed under the retina to be pumped out and the retina to re-attach. Physics or physiology of this process is not fully understood.

Surgery retinal detachment usually also involves the use of cryotherapy or laser coagulation. The laser or cryotherapy forms a permanent adhesion of the retinal break and prevent further accumulation of fluid and re-detachment. The use of a scleral buckle is a source of discussion just for complex surgeries for treatment of retinal detachment among surgeons, and studies have been conducted to compare the safety and effectiveness scleral buckling, Subtotal vitrectomy with scleral buckle vs Pars victrectomy plan without scleral buckle.

Sclera buckles are conducted using local or General anesthesia and is often done as an outpatient procedure. In the majority of treatments the buckle is left in place permanently, although in some cases the buckle can be removed after the retina heals. The buckle can also be removed in case of infection.

The relationship between the sclera buckle and syndrome of ad can exist.

The results of two randomized controlled trials 216 patients, comparison of results of retinal detachment of pneumatic retinopexy versus scleral buckle found some evidence that the scleral buckle was less likely to lead to a recurrence of retinal detachment than pneumatic retinopexy.
