What is the name of the circumferential band used to repair a retinal detachment?

The circumferential band used to repair a retinal detachment is referred to as a scleral buckle. This device is a flexible band that is placed around the eye in order to indent the sclera, which is the white outer layer of the eyeball. The scleral buckle creates a slight indentation that allows for easier attachment of the retina back to the underlying retinal pigment epithelium, thereby helping to re-establish proper anatomy and function.

By applying the scleral buckle, pressure is applied to the retina, which can help seal any tears and prevent further fluid accumulation that can lead to detachment. This technique is commonly employed in surgical practice to address retinal detachments and is considered an effective method of treatment.

The other choices represent different types of ocular devices or surgical interventions not used in this context, thus highlighting the specificity of the scleral buckle for the repair of retinal detachment.
