A Macular Pucker is a layer of scar tissue that develops on the macula, or part of the retina responsible for detailed, central vision. The scar tissue can cause the retina to wrinkle or swell, resulting in distorted or blurred vision. Macular Pucker normally affects the central vision only and can remain stable for many years. An instrument called an Optical Coherence Tomographer (OCT) is helpful in diagnosing Macular Pucker. The OCT is also useful in tracking changes associated with pucker over time. If vision changes become severe, a surgical procedure called a Vitrectomy with a membrane peel can be performed by a retina specialist. The scar tissue is removed during this procedure, which can improve the vision and reduce the distortion in some cases. Recovery time from this procedure varies in length, but full recovery can take up to three months.
