An Epiretinal membrane is scar tissue, which develops over the retina. This scar tissue can affect the macula; the central part of the retina which is critical for detailed vision. If it does, it can significantly affect vision; in particular with symptoms of distortion.

If epiretinal membranes cause visual problems, surgical removal can be very successful. This membranous scar tissue can be removed by an operation called a pars plana vitrectomy,. The operation is usually undertaken under local anaesthetic, although general anaesthetic is available. The surgery is a day case operation, and you return home that evening.
