Epiretinal Membranes

• An epiretinal membrane (ERM) is a semi-translucent, avascular, fibrocellular membrane on the inner retinal surface along the internal limiting membrane of the retina.
• ERMs may be idiopathic, or secondary to a variety of conditions such as retinal vascular occlusions, uveitis, trauma, intraocular surgery, and retinal breaks.
• Contracture of ERMs produces distortion and wrinkling of the inner surface of the retina. It is also called “cellophane maculopathy” or “pre-retinal macular fibrosis” when mild; “surface wrinkling retinopathy” or “retinal striae” when moderate; or “macular pucker” when severe.
