Macular Pucker (Epiretinal Membrane)
Macular pucker, also known as epiretinal membrane, is caused by a membrane growing on the surface of the retina and causing wrinkling of the macular anatomy. It may cause blurry vision or distortion.

The cause of epiretinal membrane formation is not known. It usually does not progress very rapidly. However, if it causes loss of vision vitrectomy surgery with membrane peeling may be warranted. During the surgery the membrane is engaged and peeled off the surface of the retina. In most cases the normal smooth surface of the macula is restored and vision improves. As with all surgeries there is a potential for complications such as infection, bleeding, retinal detachment, or further loss of vision.
