Sticky retinal tissue linked to more disability in MS

Key Takeaway

A thin layer of tissue on the retina called an epiretinal membrane (ERM) is more common in people with MS and is linked to more disability, including worse vision, thinking speed, and movement.

What They Found

Epiretinal membranes (ERM) are thin sheets of scar-like tissue that can form on the surface of the retina; they were found in about 18% of people with MS compared with 12% of healthy people. People with MS who had ERMs showed slightly worse overall disability scores and were slower on walking and hand tests, meaning ERMs were linked with everyday problems like walking more slowly or taking longer to button a shirt. Those with ERMs also had worse low-contrast vision (seeing faint letters) and signs of thinner retinal layers, which are the layers of the back of the eye that help turn light into signals for the brain. Higher ERM stage — meaning thicker or more advanced ERMs — was tied to greater disability, suggesting a dose-response link like bigger dent = more trouble. The authors think ERMs might come from inflammation or scarring cells (microglia or glial cells) and could be a sign of similar damage happening elsewhere in the brain and spinal cord.

Who Should Care and Why

People with MS and their caregivers should care because a simple eye scan could spot ERMs, which may flag higher risk for more disability and worsening symptoms. Think of ERMs like rust on one part of a car; it might point to more wear elsewhere, so noticing it could prompt closer checks and earlier help. Eye doctors and MS teams could use ERM findings to decide if a person needs more monitoring of walking, hand use, vision, or thinking speed. Caregivers can use this information to watch for small changes in daily tasks (like slower walking, trouble buttoning clothes, or difficulty reading faint print) and tell clinicians sooner. This may help guide practical steps such as vision aids, physical therapy, or changes in care routines to keep daily life safer and easier.

Important Considerations

This was an observational study, so it shows a link but cannot prove ERMs cause the extra disability — other factors could be involved. The study matched people by some key features, but ERMs might simply mark a group with more overall MS activity rather than be the direct problem themselves. More research is needed to know if treating ERMs or the underlying eye inflammation changes MS outcomes.

Whether you’ve recently been diagnosed with Multiple Sclerosis (MS) or are seeking to broaden your understanding of this complex, neurodegenerative disease, navigating the latest research can feel overwhelming. Studies published in respected medical journals like Multiple sclerosis (Houndmills, Basingstoke, England) often range from early-stage, exploratory work to advanced clinical trials. These evidence-based findings help shape new disease-modifying therapies, guide symptom management techniques, and deepen our knowledge of MS progression.

However, not all research is created equal. Some clinical research studies may have smaller sample sizes, evolving methodologies, or limitations that warrant careful interpretation. For a more comprehensive, accurate understanding, we recommend reviewing the original source material—accessible via the More Details section above—and consulting with healthcare professionals who specialize in MS care.

By presenting a wide range of MS-focused studies—spanning cutting-edge treatments, emerging therapies, and established best practices—we aim to empower patients, caregivers, and clinicians to stay informed and make well-informed decisions when managing Multiple Sclerosis.
