The retina and macula (small area of the retina responsible for fine vision) should lay flat against the back surface of the eye. Any swelling with wrinkles, creases or distortion of the retina found in the area of the macula is called macular pucker, also known as epiretinal membrane.
For mild cases of macular pucker no treatment, only regular eye exams to check for any progression is the course of treatment. In other mild to moderate cases, eye drops may be prescribed to reduce inflammation, encouraging the retina to lay flat. More severe cases can only be corrected with vitrectomy surgery.
