Medical Information & Treatment Guide
Epiretinal membrane (ICD-10: H35.37) is a thin, semi-translucent layer of fibrocellular tissue that develops on the inner surface of the macula, potentially causing distorted or blurred central vision.

Clinical information guide
An epiretinal membrane (ERM), also commonly referred to as a 'macular pucker' or 'cellophane maculopathy,' is a thin, fibrous sheet of tissue that develops over the surface of the macula. The macula is the central portion of the retina responsible for sharp, detailed, and color vision. When this membrane forms, it can contract, causing the underlying retina to wrinkle or swell (edema). This mechanical distortion interferes with the precise alignment of photoreceptors (light-sensing cells), leading to visual disturbances such as metamorphopsia (distorted vision) and decreased visual acuity.
Pathophysiologically, ERMs are composed of various cell types, including glial cells, retinal pigment epithelium (RPE) cells, and myofibroblasts. These cells migrate onto the surface of the internal limiting membrane (ILM)—the innermost layer of the retina—and begin to proliferate. As these cells mature, they create a contractile force, pulling on the retina and creating the characteristic 'puckered' appearance observed during clinical examination.
Epiretinal membranes are a significant cause of visual impairment, particularly in the aging population. According to data published by the National Eye Institute (NEI, 2023), the prevalence of ERM increases significantly with age. Research indicates that approximately 2% of individuals over the age of 50 and up to 20% of individuals over the age of 75 develop some degree of epiretinal membrane formation. The Beaver Dam Eye Study, a landmark longitudinal study supported by the National Institutes of Health (NIH), found that while many cases remain asymptomatic, the incidence of bilateral (both eyes) involvement is approximately 10% to 20% among affected individuals.
Clinically, epiretinal membranes are classified based on their etiology and their appearance on imaging:
While some patients experience no symptoms, others find ERMs profoundly life-altering. The distortion of central vision can make reading fine print, recognizing faces, and driving significantly difficult. In professional settings, individuals who rely on precision—such as architects, surgeons, or graphic designers—may find their productivity hampered. The loss of binocularity (the ability of both eyes to work together) due to image size differences (aniseikonia) can also lead to headaches, eye strain, and a loss of depth perception, impacting overall quality of life and independence.
Detailed information about Epiretinal Membrane
In the earliest stages, an epiretinal membrane may be entirely asymptomatic, often discovered during a routine dilated eye examination. The first indicator a patient might notice is a subtle blurring of central vision that is not corrected by changing glasses. Another early sign is a slight 'shimmer' or 'waviness' when looking at straight lines, such as door frames or lines of text on a page.
As the membrane thickens and contracts, the following symptoms typically emerge:
Answers based on medical literature
Epiretinal membrane is not curable through medication or eye drops, but it can be effectively treated and physically removed through a surgical procedure called a vitrectomy with membrane peeling. During this surgery, a specialist removes the fibrous tissue from the surface of the macula, allowing the retina to relax and flatten over time. While the surgery is highly successful at reducing distortion and improving clarity, it may not restore vision to 100% of its original state. Most patients see a significant improvement in their quality of life and visual function within six to twelve months post-operation. Therefore, while 'curable' in a surgical sense, the goal is often functional improvement rather than total restoration.
An epiretinal membrane typically only affects the central vision and does not lead to total blindness or a complete loss of peripheral vision. While it can cause significant blurring and distortion that makes reading or driving difficult, the side vision usually remains intact. In very severe, untreated cases, the central vision may become extremely poor, but the eye still retains the ability to see shapes and navigate environments. Early diagnosis and monitoring by a retina specialist are key to preventing the most severe forms of vision loss. Most patients maintain stable vision for many years without ever needing surgery.

> Important: While an ERM itself is rarely a medical emergency, it can be associated with retinal tears. Seek immediate care if you experience:
Research published in Ophthalmology suggests that while prevalence is similar across genders, older patients (70+) are more likely to present with bilateral involvement and more advanced membrane contraction compared to younger patients, who often present with secondary ERMs following trauma or inflammation.
The primary cause of most epiretinal membranes is the age-related separation of the vitreous gel from the retina, a process known as Posterior Vitreous Detachment (PVD). As we age, the vitreous humor (the gel filling the eye) liquefies and eventually pulls away from the retinal surface. Research published in the Journal of VitreoRetinal Diseases suggests that during this separation, microscopic remnants of the vitreous cortex or glial cells remain on the macula. These cells then proliferate and form a membrane.
Populations at the highest risk include those over age 70 and individuals with a history of retinal vascular disease. According to the American Society of Retina Specialists (ASRS, 2024), patients who have had a retinal tear or detachment in one eye have a significantly higher probability of developing an ERM in that same eye due to the release of RPE cells into the vitreous cavity.
Currently, there is no known way to prevent idiopathic epiretinal membranes, as PVD is a natural part of the aging process. However, secondary ERMs can sometimes be prevented by:
The diagnostic journey typically begins with a patient noticing visual distortion and visiting an optometrist or ophthalmologist. A definitive diagnosis is usually made by a retina specialist through a combination of clinical examination and advanced imaging.
Diagnosis is confirmed when OCT imaging reveals a hyper-reflective layer on the inner surface of the retina with associated loss of the foveal depression or evidence of intraretinal traction (tugging).
It is crucial to distinguish ERM from other conditions that cause central vision loss, including:
The primary goals of treating an epiretinal membrane are to reduce visual distortion (metamorphopsia), improve visual acuity, and stabilize the retinal structure to prevent further decline. In many mild cases, the goal is simply 'watchful waiting' to ensure the condition does not progress.
For patients with mild symptoms and good visual acuity (typically 20/40 or better), the standard of care is observation. According to clinical guidelines from the American Academy of Ophthalmology (AAO, 2024), many membranes remain stable for years and do not require surgical intervention. Patients are often given an Amsler grid to monitor their vision at home.
Medications cannot dissolve or remove an epiretinal membrane. However, they are used to manage complications like macular edema:
If vision continues to decline or distortion becomes intolerable, surgery is the only definitive treatment.
Low-vision rehabilitation and the use of magnifying devices can help patients manage the visual deficits caused by an ERM if surgery is not an option or if post-operative recovery is incomplete.
Following surgery, vision improvement is gradual, often taking 3 to 12 months for the retina to 'unwrinkle' and for the brain to adapt to the new image quality. Monitoring involves regular OCT scans to ensure the swelling has resolved.
In elderly patients, cataract progression often accelerates after vitrectomy surgery. Surgeons may recommend a combined 'phaco-vitrectomy' procedure to address both the cataract and the ERM simultaneously. Talk to your healthcare provider about which approach is right for you.
While diet cannot cure an ERM, maintaining retinal health is vital. Research published in JAMA Ophthalmology emphasizes the importance of antioxidants. A diet rich in leafy greens (lutein and zeaxanthin), omega-3 fatty acids (found in salmon and walnuts), and Vitamin C may support overall macular health and potentially improve surgical outcomes.
General cardiovascular exercise is encouraged to maintain healthy blood flow to the eyes. However, immediately following vitrectomy surgery, patients must avoid heavy lifting, bending over, or strenuous activity for several weeks to prevent fluctuations in intraocular pressure.
If a gas bubble is used during surgery (though less common for simple ERM than for macular holes), specific 'face-down' positioning may be required for several days to ensure proper healing. Proper rest is essential for the neurological adaptation to improved visual signals post-surgery.
Vision loss can be a significant source of anxiety. Evidence-based techniques such as mindfulness-based stress reduction (MBSR) have been shown to help patients cope with chronic visual distortions and the recovery process.
There is no clinical evidence that acupuncture, yoga, or herbal supplements can remove an epiretinal membrane. Patients should be cautious of 'natural' eye drops marketed to dissolve membranes, as these are not supported by scientific data.
Caregivers should ensure the home is well-lit to assist the patient with diminished central vision. Helping the patient with Amsler grid monitoring and ensuring they attend all follow-up appointments with the retina specialist is critical for long-term success.
The prognosis for epiretinal membrane is generally good, especially with modern micro-incisional vitrectomy surgery. According to a study in the American Journal of Ophthalmology (2023), approximately 80% to 90% of patients experience a significant improvement in visual distortion, and the majority gain at least two lines of visual acuity on the Snellen chart. However, vision rarely returns to a 'perfect' 20/20 state if it was significantly damaged before surgery.
If left untreated, an ERM can lead to permanent central vision loss and chronic macular edema. Surgical complications, though rare (occurring in less than 1% of cases), include:
Long-term management involves periodic eye exams to monitor for recurrence, which occurs in about 5% of cases. Patients should continue to use an Amsler grid at home to detect any new changes early.
Most people with ERM continue to lead full, active lives. Utilizing high-contrast settings on digital devices and using bright, direct task lighting for reading can significantly mitigate the impact of the condition.
Contact your retina specialist if you notice a sudden increase in distortion, a new blind spot, or if your vision does not seem to be improving as expected in the months following surgery.
There are currently no eye drops, vitamins, or medications that can dissolve or remove an epiretinal membrane. Because the membrane is a physical, fibrous tissue similar to a scar, it must be mechanically removed by a surgeon if it is causing significant visual problems. Some eye drops, such as NSAIDs or steroids, may be prescribed to treat the swelling (macular edema) associated with the membrane, but they do not address the membrane itself. Patients should be wary of any products claiming to 'naturally' cure a macular pucker. Always consult a licensed ophthalmologist before starting any new treatment for eye conditions.
Surgery is not always necessary for an epiretinal membrane and is typically only recommended when the distortion or blurring significantly interferes with a patient's daily activities. Many people have mild membranes that remain stable for decades without ever progressing to a stage that requires intervention. Doctors usually follow a 'watchful waiting' approach, monitoring the membrane with OCT scans every six to twelve months. If the patient's vision is 20/40 or better and they are not bothered by the distortion, surgery is often deferred. The decision to operate is highly individualized based on the patient's visual needs and lifestyle.
The initial physical recovery from vitrectomy surgery usually takes about two to four weeks, during which time the eye may feel scratchy or red. However, visual recovery is a much slower process, as the retina needs time to 'unwrinkle' and heal after the membrane is removed. Most patients begin to notice an improvement in distortion within one to three months, but the full visual benefits may not be realized for up to a year. During the first few weeks, patients must avoid strenuous activity and follow a strict eye-drop regimen. Regular follow-up appointments are necessary to monitor the healing process and check for any complications.
Currently, there is no strong evidence to suggest that idiopathic epiretinal membranes are a strictly hereditary condition. Most cases are considered 'sporadic,' meaning they occur due to the natural aging process of the eye rather than being passed down through genes. However, certain underlying conditions that can lead to secondary membranes, such as diabetes or certain retinal dystrophies, may have a genetic component. If several family members have had retinal issues, it is wise to inform your eye doctor. Regardless of family history, everyone over the age of 50 should have regular dilated eye exams.
In general, normal exercise and physical activity do not cause an epiretinal membrane to worsen or pull more on the retina. The forces involved in most exercises are not strong enough to affect the microscopic cellular layers on the macula. However, if you have recently undergone surgery for an ERM, you must strictly follow your surgeon's restrictions regarding lifting and strenuous activity. High-impact sports that carry a risk of eye trauma should always be performed with protective eyewear. Maintaining good cardiovascular health through exercise is actually beneficial for overall retinal circulation.
While both conditions affect the macula and can cause similar symptoms like distortion, they are distinct anatomical problems. An epiretinal membrane is a layer of extra tissue growing *on top* of the macula, while a macular hole is an actual *break* or opening through the layers of the macula. Sometimes, the traction from an epiretinal membrane can actually pull on the retina so hard that it causes a macular hole to form. Both conditions are treated with vitrectomy surgery, but the surgical techniques and recovery requirements (such as face-down positioning) differ. A retina specialist uses OCT imaging to clearly distinguish between the two.
Whether you can drive with an epiretinal membrane depends on the severity of the vision loss and the legal requirements for visual acuity in your jurisdiction. Many patients with an ERM in only one eye can drive safely because the healthy eye compensates for the distortion in the affected eye. However, if the membrane affects both eyes or causes significant loss of depth perception, driving may become hazardous. It is important to have your vision tested by a professional to ensure you meet the safety standards for operating a vehicle. If you feel unsafe or struggle to see road signs, you should refrain from driving until treated.
While surgery for an epiretinal membrane is very effective at reducing distortion, it is important to have realistic expectations, as vision may not return to 100% 'normal.' Most patients experience a significant reduction in the 'waviness' of lines and an improvement in the clarity of text. The degree of recovery often depends on how long the membrane was present and how much damage it caused to the underlying retinal cells. If the retina was severely swollen or distorted for a long time, some permanent changes may remain. However, the vast majority of patients are very satisfied with the improvement in their functional vision post-surgery.
