Comparison of Anatomical and Functional Outcomes of Laser Photocoagulation and Cryopexy in Patients with Rhegmatogenous Retinal Detachment Treated with Pneumatic Retinopexy

"Pneumatic retinopexy with transscleral cryopexy is a procedure used to treat certain types of rhegmatogenous retinal detachments.~Procedure steps:~Transscleral cryopexy: in this first step, the surgeon uses a cryoprobe applied to the sclera directly over the retinal tear. The cryoprobe emits extreme cold, creating a small, localized freeze that reaches the retina and seals the tear by causing a controlled scar to form. This scar tissue holds the retina in place and prevents further fluid from passing through the tear.~Gas bubble injection: after the cryopexy, a small gas bubble (usually sulfur hexafluoride (SF6) or perfluoropropane (C3F8)) is injected into the vitreous cavity. This bubble applies upward pressure on the retina, gently pressing it against the back wall of the eye, which aids in reattaching the retina.~Head positioning: for several days following the procedure, the patient must keep their head in a specific position so the gas bubble remains aligned with the retinal tear."

"Pneumatic retinopexy with laser photocoagulation is a minimally invasive procedure used to repair certain types of rhegmatogenous retinal detachments.~Procedure steps:~Gas bubble injection: a small gas bubble, usually sulfur hexafluoride (SF6) or perfluoropropane (C3F8), is injected into the vitreous cavity which rises and applies pressure to the detached retina, pressing it back against the eye wall and helping to reapproximate the retinal layers.~Laser photocoagulation: once the retina is positioned correctly, laser is used to create small burns around the retinal tear. This laser application causes a mild inflammatory response, creating a scar around the tear and effectively welding the retina to the underlying tissue. This seal prevents fluid from reaccumulating beneath the retina.~Head positioning: following the procedure, the patient must keep their head in a specific position for several days. This positioning ensures that the gas bubble stays aligned with the retinal tear."
