Epiretinal Membrane

An epiretinal membrane (also called a macular pucker) is a thin, translucent layer of scar tissue that forms on the surface of the retina over the macula. As this membrane contracts, it can wrinkle or pucker the macula, causing distorted or blurry central vision. Epiretinal membranes are most common in people over 50 and may develop after a posterior vitreous detachment, eye surgery, or retinal inflammation. Mild cases may not require treatment, but when vision is significantly affected, a vitrectomy with membrane peeling can improve visual function.
