Which procedure involves laser treatment around a retinal tear to prevent detachment?

Laser retinopexy is the correct answer because it is specifically designed to treat retinal tears and holes, ultimately helping to prevent retinal detachment. In this procedure, a laser is used to create small burns around the area of the tear. These burns promote the formation of scar tissue, which effectively seals the retina to the underlying tissue and helps to secure it in place. This technique is minimally invasive and can be performed on an outpatient basis, making it a preferred method for managing this particular type of retinal issue.

In contrast, retinal cryopexy involves freezing the area around the retinal tear instead of using a laser. While effective, it is generally less commonly used nowadays due to the advancements in laser technology that provide more precision and comfort to the patient. Pneumatic retinopexy is a procedure where a gas bubble is injected into the eye to push the retina back into its proper position; it is typically used after a detachment has already occurred rather than as a preventive measure. Scleral buckling involves placing a band around the eyeball to alleviate the tension on the retina, helping to treat or prevent detachment, but it is a more invasive surgical intervention compared to laser retinopexy.
