An epiretinal membrane is a thin layer of tissue that forms on the surface of the macula, the part of the retina responsible for sharp central vision. It can cause blurred or distorted vision, such as straight lines appearing wavy. ERMs are most common in people over 50 and may develop after eye surgery or inflammation.
Treatment is only recommended if symptoms affect daily activities like reading, driving, or recognising faces. Surgery involves gently removing the membrane using keyhole techniques and is usually performed as a day case under local anaesthetic. Some ERMs remain stable and do not require treatment.
