What is a Macular Pucker?
Macular pucker (also called epiretinal membrane) happens when wrinkles, creases or bulges form on your macula. The macula must lie flat against the back of your eye to work properly. When the macula wrinkles or bulges, your central vision is affected.
With macular pucker, things can look wavy, or you may have trouble seeing details. You might notice a gray or cloudy area in your central vision. You may even have a blank spot in your central vision. Macular pucker will not affect your peripheral (side) vision.
