![]() The gas bubble that results from the surgery is slowly reabsorbed into the bloodstream over a period of two to eight weeks, depending on the concentration of gas that is used by your retinal specialist. Macular hole surgery is done as an outpatient procedure and usually can be performed in one hour or less. ![]() ![]() There is also approximately a 9- to 10-percent chance of a hole forming in the opposite eye with time. Without treatment, the blind spot caused by the macular hole usually enlarges, and most patients’ ultimate visual acuity is 20/400 or worse (the size of the big “E” on the eye chart.) Macular holes rarely close without surgery. With these relatively low risks, many patients elect to proceed with surgery with a realistic expectation of better vision when the repair is performed in a timely fashion. These risks include cataract formation, retinal tears and detachment, failure of hole closure and infection or bleeding in the eye. As with any surgery, there are surgical risks. This requires face-down positioning to allow the gas bubble to press against the hole to help it close.Īs we have improved techniques of hole closure during the last 10 years, face-down positioning time has been decreased, and the rate of hole closure has improved to 90 percent or greater. In the early 1990s, however, it was discovered that if the vitreous gel was removed surgically from the eye and the vitreous cavity was filled with a temporary gas bubble, the hole would seal itself, resulting in visual improvement. Different attempts were made to try to repair such holes surgically, with limited success. Prior to the early 1990s, there was no cure for macular holes.
