Which procedure uses a silicone band or sponge to repair a detached retina?

• A. Scleral buckle
• B. Vitrectomy
• C. Enucleation
• D. Ocular prosthesis

Answer: (A)

The concept is repairing a detached retina by creating an external indentation with silicone material. In scleral buckling, a silicone band or a soft silicone sponge is placed around the outside of the eye (the sclera). This external buckle folds the sclera inward, forming an indent that supports the retina and helps seal the retinal tear, allowing subretinal fluid to reabsorb and the retina to reattach without entering the vitreous cavity. This approach is different from other procedures: vitrectomy works from inside the eye, removing the vitreous gel and often using a tamponade agent; enucleation involves removing the entire eye; and an ocular prosthesis is a cosmetic device worn after eye removal.
