CHAPTER 72 A retinal detachment is the separation of the retina from the internal wall of the eye. Possible instruments needed for repair of a detachment include a basic eye set. A brief description of the possible methods of repairing a detached retina follows: 1. Scleral buckling. This procedure places a silicone band, sponge, or other device against the outside of the eye at the area of the detachment. This presses the wall of the eye into the retina to encourage reattachment. 2. Pneumatic retinopexy. This procedure uses gas, which is injected into the posterior chamber. By positioning the patient, the gas bubble is forced against the wall of the eye where the detachment is. The gas used will expand and later diffuse in 7 to 10 or 30 to 50 days, depending on which gas is used. 3. Laser photocoagulation. This procedure uses a laser beam to treat the retinal hole. The laser may be used in conjunction with scleral buckling or pneumatic retinopexy.
