Understanding Epiretinal Membranes
An epiretinal membrane is a thin layer of scar-like tissue that forms on the surface of the retina. The retina is the delicate, light-sensitive tissue at the back of your eye that captures images and sends them to your brain. When this extra layer of tissue grows across the central part of the retina, called the macula, it can pull on the retina and cause it to wrinkle or pucker. This is why the condition is also commonly known as a macular pucker or cellophane maculopathy.
The macula is responsible for your sharp, central vision. It is the part of your eye you rely on for reading, recognizing faces, and seeing fine details. When an epiretinal membrane distorts the macula, your central vision may become blurry or wavy. Objects may look bent or slightly different in size compared to how they appear when viewed with your other eye. Many people notice these changes gradually over weeks or months.
Epiretinal membranes most commonly develop as a result of natural aging changes inside the eye. The vitreous is a clear, gel-like substance that fills the inside of your eye. As people age, the vitreous slowly shrinks and can pull away from the retina in a process called a posterior vitreous detachment. This separation is normal and happens to most people during the later decades of life. However, when the vitreous pulls away, it can sometimes leave behind microscopic damage on the retinal surface. Cells then migrate to the area and form a thin membrane of tissue.
In some cases, epiretinal membranes can also develop after eye surgery, following inflammation inside the eye, after a retinal tear or detachment, or in connection with other eye conditions. In many cases, though, no specific cause is found. The membrane simply forms on its own as part of the aging process.
Not all epiretinal membranes cause noticeable vision problems. In mild cases, the membrane may be very thin and cause little to no distortion. You might not even know it is there unless your eye doctor discovers it during a routine examination. Many people with mild membranes continue to see well and do not need treatment.
When the membrane is thicker or begins to contract, however, it can tug on the retina and cause the macula to wrinkle. This wrinkling leads to symptoms such as blurry or distorted central vision, difficulty reading small print, straight lines appearing wavy or crooked, and a noticeable difference in vision between your two eyes. These symptoms can range from mild to significant depending on how much the membrane has affected the retinal surface.
Who Is a Good Candidate for Treatment
If your epiretinal membrane is mild and your vision is still relatively clear, your care team at Washington Eye Institute may recommend a period of careful monitoring rather than immediate treatment. Many epiretinal membranes remain stable for months or even years without getting worse. During this time, your retina specialist will schedule regular follow-up visits to check the membrane and track any changes in your vision.
Observation is a reasonable approach when the membrane is thin, your daily activities are not significantly affected, and your visual acuity remains good. There is no medication, eye drop, or laser treatment that can remove an epiretinal membrane. Because of this, the main decision is between continuing to monitor the condition and proceeding with surgery when the time is right.
Surgery is typically considered when an epiretinal membrane is causing enough vision distortion to interfere with your everyday life. If you find that reading, driving, or other important tasks have become noticeably more difficult because of blurry or wavy vision, it may be time to discuss surgical options with your care team. The goal of surgery is to gently remove the membrane from the surface of the retina, allowing the macula to flatten and your vision to improve.
Your retina specialist will evaluate several factors before recommending surgery. These include the severity of your symptoms, the thickness of the membrane, the degree of retinal wrinkling seen on imaging scans, how long you have had the condition, and the overall health of your eye. Surgery tends to produce better outcomes when it is performed before the membrane has caused prolonged or severe distortion.
Certain factors may influence whether surgery is recommended and what results you can expect. If the epiretinal membrane has been present for a long time and has caused significant changes to the retinal structure, recovery of vision may be more limited. Your care team will use specialized imaging, including optical coherence tomography (a detailed scan that creates cross-sectional images of your retina), to assess the extent of the membrane and how much it has affected the underlying tissue.
Other eye conditions, such as cataracts, glaucoma, or macular degeneration, may also be considered when planning your treatment. If you have a cataract that is affecting your vision, your surgeon may recommend addressing both the cataract and the epiretinal membrane during the same procedure or in a planned sequence. Your care team will work with you to develop an approach that takes your complete eye health into account.
How Epiretinal Membrane Treatment Works
The surgical treatment for an epiretinal membrane is called a vitrectomy with membrane peeling. A vitrectomy is a procedure in which the vitreous gel inside the eye is carefully removed and replaced with a clear saline solution. Removing the vitreous gives your surgeon a clear view of the retinal surface and direct access to the membrane. Your eye will naturally produce fluid that takes the place of the removed vitreous over time.
The procedure is performed using very small instruments inserted through tiny openings in the white part of the eye. These openings are typically less than one millimeter in size. A microscope and specialized lighting allow your surgeon to see the retina in great detail throughout the procedure.
Once the vitreous has been removed, your surgeon uses extremely fine forceps to gently grasp the edge of the epiretinal membrane and peel it away from the retinal surface. This step requires great precision because the membrane is very thin and lies directly on the delicate retina. A special dye may be applied to the retinal surface to make the membrane more visible and easier to identify during removal.
In some cases, a second, even thinner layer called the internal limiting membrane may also be peeled away. This additional step can help reduce the chance of the epiretinal membrane growing back. Your surgeon will determine whether this extra step is appropriate based on the specifics of your condition.
Epiretinal membrane surgery is typically performed as an outpatient procedure, meaning you go home the same day. Most patients receive local anesthesia, which numbs the area around the eye so you do not feel pain during the procedure. You may also receive light sedation to help you relax. General anesthesia is used less commonly but may be an option depending on your health and preferences. Your care team will discuss the best approach for your comfort before the day of surgery.
After the membrane is removed, the retina is given the opportunity to gradually flatten back toward its normal shape. The saline solution that replaces the vitreous supports the retina during healing. In most cases, no gas bubble or special positioning is required after epiretinal membrane surgery, which makes the recovery process more straightforward compared to some other retinal procedures. Your surgeon will place a protective shield over your eye at the end of the procedure, and you will receive instructions for eye drops and follow-up care.
Types of Treatment Options Available
For mild epiretinal membranes that are not significantly affecting your vision, observation is the most common approach. During the monitoring period, your retina specialist will schedule visits at regular intervals to examine your retina and check your vision. These visits typically include a comprehensive eye exam and optical coherence tomography imaging to measure the thickness of the membrane and look for any changes in the retinal structure.
Monitoring is not a passive approach. It is a deliberate decision made in partnership with your care team. The purpose is to track the membrane carefully so that if your vision begins to decline, treatment can be offered at the most appropriate time. Many patients do well with observation alone and may not require surgery.
When an epiretinal membrane is causing meaningful vision problems, vitrectomy with membrane peeling is the standard surgical treatment. This procedure directly addresses the cause of vision distortion by physically removing the membrane from the retinal surface. Modern surgical techniques use very small incisions that typically do not require stitches and allow for faster healing.
The decision to proceed with surgery is based on your symptoms, the findings on your retinal imaging, and your own goals for your vision. Your care team will help you weigh the potential benefits of surgery against the small risks involved. Most patients who undergo this procedure experience meaningful improvement in their vision, though the degree of improvement can vary depending on how long the membrane has been present and how much it has distorted the retina.
In some situations, your surgeon may recommend combining epiretinal membrane surgery with cataract surgery. Cataracts, which are a clouding of the natural lens inside the eye, are common among older adults and can develop or progress more quickly after vitrectomy. By addressing both conditions in one surgical session, your care team can reduce the total number of procedures and recovery periods you experience.
Whether a combined approach is right for you depends on the current state of your lens, the severity of your epiretinal membrane, and other individual factors. Your care team at Washington Eye Institute will discuss all options with you and help you make an informed decision.
It is important to understand that not every epiretinal membrane requires treatment. If the membrane is discovered incidentally during an eye exam and is not causing symptoms, your care team may simply note its presence and continue to monitor it during your regular visits. Many epiretinal membranes remain stable and do not progress to the point of requiring surgery. Knowing that the membrane is there and having it tracked over time gives you and your care team the information needed to act if and when it becomes appropriate.
What to Expect with Epiretinal Membrane Treatment
If you and your care team decide that surgery is the right choice, you will have a preoperative evaluation at Washington Eye Institute. This visit includes a thorough eye examination, detailed retinal imaging, and a discussion of what to expect during and after surgery. You will receive instructions about any medications you should continue or pause before the procedure, as well as guidelines about eating and drinking on the day of surgery.
You will need to arrange for someone to drive you home after the procedure, as you will not be able to drive yourself. It is helpful to plan ahead so that you have someone available to assist you on the day of surgery and during the first day or two of recovery at home.
On the day of surgery, you will arrive at the surgical facility and be prepared for the procedure. Eye drops will be placed in your eye to dilate your pupil and numb the surface. Once you are comfortable and the anesthesia has taken effect, the surgeon will begin the vitrectomy and membrane peeling. The procedure typically takes between 30 minutes and one hour, depending on the complexity of the membrane and whether any additional steps are needed.
You may be aware of bright lights during the surgery, but you should not feel pain. Your care team will be with you throughout the procedure to monitor your comfort and safety.
After surgery, it is normal for your eye to feel mildly sore, scratchy, or irritated for the first few days. Your vision may be blurry initially, and you might notice some redness or mild swelling around the eye. These symptoms are expected and typically improve steadily during the first week. You will be given prescription eye drops to prevent infection and reduce inflammation, and you will need to use these drops as directed for several weeks.
During the first week, your care team will ask you to avoid strenuous activities, heavy lifting, and bending forward. You should also avoid rubbing your eye or getting water directly in it while showering. Most people feel comfortable returning to light daily activities within a few days, though your surgeon will provide specific guidance based on your individual situation.
Vision improvement after epiretinal membrane surgery is usually gradual. Some patients notice an improvement within the first few weeks, while for others, vision continues to improve over three to six months or longer. The brain and the retina need time to adjust as the macula slowly flattens and heals. Straight lines that previously appeared wavy may gradually become straighter, and overall clarity can continue to improve for several months after the procedure.
The final level of vision improvement depends on several factors, including how long the membrane was present before surgery, the degree of retinal distortion it caused, and the overall health of your retina. Your care team will monitor your progress at follow-up visits and discuss what changes you are experiencing over time.
As with any surgical procedure, epiretinal membrane surgery carries some risks. The most common risk is the development or progression of a cataract in the months following surgery, particularly for patients who have not already had cataract surgery. Other less common risks include retinal detachment, infection, increased eye pressure, bleeding inside the eye, and recurrence of the epiretinal membrane.
Serious complications are uncommon, and your surgical team takes careful precautions to minimize risks. Before your procedure, your care team will discuss all potential risks and benefits with you so that you can make a fully informed decision. If you experience any sudden changes in your vision, flashes of light, a significant increase in floaters, or severe pain after surgery, you should contact Washington Eye Institute promptly.

Frequently Asked Questions About Epiretinal Membranes
The decision to have surgery depends primarily on how much the epiretinal membrane is affecting your vision and your daily life. If you are experiencing significant blurriness, distortion, or difficulty with tasks like reading and driving, surgery may be a good option. Your retina specialist will use detailed imaging and vision testing to assess the severity of the membrane and help you decide whether surgery is appropriate at this time.
If your membrane is mild and you are managing well with your current vision, observation with regular monitoring may be the better choice. There is no single threshold that applies to everyone. Your care team will consider your specific situation, symptoms, and goals when making a recommendation.
Most patients are able to return to light daily activities within a few days after surgery. However, full vision recovery is a gradual process that often takes several months. Many patients notice some improvement in the first few weeks, with continued progress over three to six months as the retina heals and flattens. The timeline can vary based on the severity of the membrane and how long it was present before surgery.
Your care team will schedule regular follow-up visits to track your recovery and will let you know when it is safe to resume specific activities such as driving, exercise, and returning to work.
In most cases, once an epiretinal membrane is surgically removed, it does not return. However, there is a small chance that a new membrane could form after surgery. Your surgeon may take additional steps during the procedure, such as peeling the internal limiting membrane, to further reduce this possibility.
If a membrane does recur and causes significant symptoms, a second surgery may be considered. Your care team will continue to monitor your retina at follow-up visits to watch for any signs of recurrence.
Many patients experience meaningful improvement in their vision after epiretinal membrane surgery. Central vision often becomes clearer, and distortion of straight lines typically decreases. However, the degree of improvement varies from person to person. Factors that influence the outcome include how long the membrane was present, how much distortion it caused, and the overall health of the retina.
Some patients achieve very good vision after surgery, while others may have some residual blurriness or mild distortion. Your care team will give you a realistic expectation of what improvement is possible based on your individual circumstances.
If your epiretinal membrane is mild and not significantly affecting your vision, choosing observation is a perfectly reasonable approach. Many membranes remain stable and do not worsen over time. Your retina specialist will continue to monitor the membrane at regular intervals to detect any changes early.
If the membrane does progress and your vision worsens, surgery can be discussed at that point. It is generally better to have surgery before the membrane causes prolonged or severe distortion, as this tends to result in better visual outcomes. Your care team will help you recognize the signs that it may be time to reconsider surgery.
Most patients report that epiretinal membrane surgery is not painful. Local anesthesia is used to numb the eye and the surrounding area, and many patients also receive mild sedation to help them feel relaxed during the procedure. You may be aware of light and gentle pressure, but you should not feel sharp pain.
After surgery, some mild discomfort, scratchiness, or a foreign-body sensation in the eye is normal for the first few days. This is typically manageable and improves quickly. Your care team will provide guidance on managing any post-surgical discomfort and will be available if you have concerns during your recovery.
