Doctors recommend eye membrane surgery to repair a preretinal or epiretinal membrane, called a macular pucker, only when a patient's vision becomes so poor that it interferes with normal activities, according to the National Eye Institute. Treatments including eye drops and drugs do not improve vision impaired by macular pucker.
The need for eye membrane surgery, called a vitrectomy, is rare, notes the National Eye Institute. In many epiretinal membrane cases, patients who experience mild blurriness or distortions in their vision accommodate to the vision changes. Doctors do not treat them because the changes do not disturb the patients' driving or other routine activities. Scar tissue creates a macular pucker, and in some instances, the condition disappears spontaneously, as the tissue separates from the retina on its own.
