Epiretinal membrane is a scar tissue-like membrane that forms over the macula, the tissue near the center of the eye's retina that's responsible for central vision. It's also known as macular pucker, macular wrinkling, scar tissue or cellophane membrane. Many cases of epiretinal membrane are mild enough that no treatment is necessary. If vision is significantly affected, your doctor may recommend a vitrectomy to remove the membrane. The procedure improves vision by smoothing out the macula. For more details, see treatment options.
Epiretinal membrane typically progresses slowly and affects central vision by causing blurring and distortion. As it progresses, the pulling of the membrane on the macula may cause swelling.
This condition most commonly affects older adults and may be associated with diabetic retinopathy, retinal detachment, trauma or other disorders.
