An epiretinal membrane (also known as a macular pucker) is a thin scar-like tissue that forms over the retina. It grows directly over the macula, which is the tiny portion of the retina that is responsible for sharp, central vision.
Symptoms and Treatment:
Sometimes, the epiretinal membrane can be very mild, having no effect on vision at all. In other cases, the epiretinal membrane may worsen over time and cause blurring and distortion to central vision. In symptomatic patients, surgery may be necessary to remove the membrane.
