![]() ![]() Most retina surgery is outpatient surgery and can be done under local anesthetic and mild sedation. Head positioning for retinal detachments depends upon the location of the retinal tear(s). In cases of macular holes, a face down position is common. Your surgeon will ask you to position yourself in a specific way during healing and that position is dependent on what part of the retina was repaired. The line will move lower each day and your field of vision will get larger as the natural fluid continues to replace the bubble.Īs long as any of the gas bubble remains in your eye you must not fly in an airplane because the bubble can expand in the reduced pressure of the cabin causing severe pain and possible loss of sight. As the bubble dissipates you will see a line across your vision where the gas meets the newly forming fluid which is gradually replacing the bubble. The gas bubble blurs your vision while it is in place. Sulfur hexafluoride (SF 6) dissipates in 10 to 14 days, and perfluoropropane (C 3F 8), in 55 to 65 days. Air dissipates and is replaced by natural fluid in 5 to 7 days. Each of the gases dissipates and is replaced by natural fluid, but the time for complete dissipation varies. ![]() The gases commonly used are sulfur hexafluoride (SF 6) and perfluoropropane (C 3F 8), and air. In the case of a macular hole, the gas is used to allow the hole to slide closed by surface tension. In the case of the retinal detachment (specifically a rhegmatogenous retinal detachment which is caused by a retinal tear or retinal hole), the gas is used to block (tamponade) the migration of fluid to through the tear to underneath the retina. The most common use of gas is for repair of a retinal detachment or macular hole. Not all retina surgery requires gas to be injected into the eye. A vitrectomy, the procedure to remove the vitreous, allows the retina specialist specialist to work on the retina.Ī vitrectomy (removal of the vitreous humor gel) is done for the following conditions:Ī tamponade in medical terms is something used to close or block a wound or body cavity to stop bleeding or fluid leakage. ![]() To safely work on the retina, your retina specialist must be able to safely access the inner layer of the eye. Not all retina surgery requires injection of a gas bubble. ![]()
