An epiretinal membrane is a fine scarring on the surface of the retina at the back of the eye. The retina is a nerve tissue, which is like wallpaper that covers the back wall of the eye. The center of the retina is called a macula, which provides us with detailed central vision. If there is an abnormality at that macula, then it affects the central vision.
Seven percent of all people have an epiretinal membrane but only in 1% does it progress and require surgery. This surgery is a vitrectomy (with instruments placed into the eye to remove the vitreous gel) followed by a membrane peeling (with fine forceps to gently peel the membrane away from the retina.)
It is important to use your Amsler grid on a regular basis to detect if there is any distortion that is worsening. If there is, please contact us promptly. Otherwise, your epiretinal membrane can be checked on a periodic basis.
