Macular Translocation Surgery is for patients losing their vision as a result of the eye disease macular degeneration.
Macular Degeneration attacks the central vision of those with the eye disease and macular translocation surgery can be used to lift the macula away from the underlying blood vessels and attach it to a new and more healthier portion. This will restore the central vision that is damaged by macular degeneration.
Macular translocation surgery is only meant to treat patients with wet macular degeneration. In this form of macular degeneration leaking blood vessels have formed beneath the retina and moving the macula to a more healthier spot will improve central vision. This eye surgery is not recommended for every patient who has macular degeneration and best results have been shown for those people who are in the early stages of the eye disease.
In macular translocation surgery, the eye surgeon will pinch the outer part of the eye called the sclera. With the sclera pinched, the surgeon will place a suture into the wall of the eye to keep it pinched. This will shorten its length as well as buckle the retina.
Once the suture is in place, the eye surgeon will inject a saline solution into the eye under the retina, causing it to lift up, allowing it to be moved approximately 0.3 and 0.4 mm without detaching it. After the retina is moved, a gas bubble is injected into the eye to hold the retina in location until it heals.
Another side benefit of relocating the retina during macular translocation surgery is it provides access to the previously covered blood vessels thus allowing treatment without harming the retina.
Duke Eye Center have refined macular translocation surgery into a technique called macular translocation surgery with 360 degree peripheral retinectomy (MT360). This is a two-stage surgery that involves rotating the retina to move the macula away from the abnormal blood vessels associated with macular degeneration and then correcting the tilted visual field by rotating the eye.
Macular translocation surgery does have some risks associated with it including retinal detachment, bleeding, double vision, and residual tilting of vision. All of these risks can be either corrected surgically or with special glasses.
