Epiretinal membrane
The epiretinal membrane, also called macular pucker, is a thin membrane that forms on the macula (the part of the retina responsible for the vision of detail), which can be wrinkled and then distort the vision.
​
There are several causes. The most important thing is when vitreous humor, with the age, shrinks and separates from the retina. It can also occur through intraocular inflammation, diabetic retinopathy, venous occlusive disease and post-traumatic situations.
The typical symptom is distorted vision, the straight lines seem sinuous, curved, since the membrane collapses and retracts from the retina.
