What is Macular Pucker?
A macular pucker is a condition in which a thin, nearly transparent membrane forms over the surface of the central retina, an area called the macula, and causes the normally smooth surface to become irregular. The condition is also referred to as an epiretinal membrane or a “wrinkle” on the surface of the retina.
While retinal vascular diseases or eye inflammation may cause a macular pucker, the condition is most commonly associated with increasing age. As a part of the normal aging process, the vitreous gel liquefies, shrinks, and separates from the retina. In some people, as the edge of the vitreous separates, it leaves behind a thin film of tissue or damages the surface of the macula. In an attempt to heal, the eye forms a thin “scar” or membrane over this area. The membrane may then contract and cause distortion of the surface of the macula. As a result, central vision may become distorted and blurred.
Treating a Macular Pucker
A surgical procedure can be performed to remove a macular pucker. During the surgery, a portion of the vitreous gel is removed and the membrane is carefully peeled and lifted off of the surface of the macula.
The vitreous gel is replaced with a clear solution, similar to what the eye produces normally. Once the membrane has been removed, the macula will have a chance to regain its normal shape and improve the blurriness and distortion in the vision. The surgery is typically performed as an outpatient procedure under local anesthesia.
Eighty-five to ninety percent of patients notice a measurable improvement in vision after this surgery. With a good outcome, eyesight will be improved and the distortion in vision will be reduced.
