An epiretinal membrane is a condition in which a very thin layer of scar tissue is formed over retina. Macula, the part of the eye affected by this membrane, is responsible for a person’s sharpest vision. A person with this problem would experience blurring and distortion of vision. If these two symptoms are severe and are disrupting day to day activities, then ophthalmologist would suggest a retinal membrane surgery. Since there is no medication (like drops) for this problem, removal of membrane surgically is the only way out.
Epiretinal removal involves vitrectomy eye surgery followed by membrane peeling. Three holes are made in the effected eye; the jelly like substance that fills the center of eye called vitreous humor is removed with the help of instruments (vitrectomy). The vitreous fluid is replaced by natural fluid produced by eye, thus not causing any permanent damage to the eye. The membrane is peeled off retina with the help of fine forceps (membrane peeling). A small air bubble is left inside the eye at the end of surgery, which helps in healing process. This bubble is expected to disappear within a week. The three holes, made at the beginning of the surgery, heal and close by themselves. No stitches are required for this procedure which generally takes less than an hour to perform. This procedure is done under local anesthesia, but you are required to remain still during the whole process. After a surgery, a shield is placed on your eye and can be removed after a day.
