The macula is the small, central part of the retina that allows you to read and see fine details. Damage to the macula can significantly affect central vision.
A macular pucker occurs when a clear membrane, like cellophane, covers the surface of the macula. The membrane is made up of a thin layer of cells that settle and grow on the surface of the retina. This condition can occur at any age, but more often occurs in patients over the age of 40. Often these membranes remain completely flat and cause no vision problems. However, in some cases, the membrane will start to contract on the surface of the macula which leads to wrinkling or puckering of the retina beneath. This puckering can impair central vision.
