It is placed behind the eyelids, and under the conjunctiva and tenon capsule (clear/white external “skin” layer of the eye) and, therefore, is not seen. A scleral buckle is a thin silicone band that is placed around the eye, like a belt, and supports the retina from the outside. The goal is for the retina to stay reattached once the gas bubble goes away or once the oil bubble is removed.Īnother procedure for the repair of retinal detachment is a scleral buckle. An oil bubble is usually left in the eye for 3-6 months, but sometimes longer or shorter, and needs a separate procedure to remove the oil in the future. A gas bubble lasts about a month and goes away on its own. This bubble serves to push the retina back into the correct position. Finally, an inert gas bubble or silicone oil bubble are used to fill the vitreous cavity in the eye. The laser is then used to seal the retinal tears. Vitrectomy is where most of the vitreous gel is removed, and the retina flattened from the inside of the eye. Surgical correction of a detached retina includes vitrectomy surgery. This seals the break to the wall of the eye and is the key step in repairing a retinal detachment. Pneumatic retinopexy is an in-office procedure in which gas is injected into the vitreous cavity to re-attach the retina and cryopexy (freezing), or laser, is used to demarcate or weld around the retinal break. There are several ways in which retinal detachments can be repaired, depending on many factors such as the age of the patient, the location, distribution and number of retinal breaks, among others. The portion of the retina that is detached does not have normal vision and is often described by patients as “a veil, curtain or shadow coming over the vision”. Once a tear is formed, fluid can get underneath the retina, and cause it to detach. Holes or tears, in turn, can happen because of pulling by the liquifying vitreous gel (a normal aging change) or can be traumatic. Rhegmatogenous detached retinas are the most common detachments and happen because of a hole or tear in the retina, usually in the peripheral retina. What is a rhegmatogenous retinal detachment?
