Epiretinal membrane (ERM) removal is a vitreoretinal surgery to peel a thin layer of scar-like tissue from the surface of the macula. The aim is to reduce distortion and improve central vision.
The Surgical Procedure
Through small ports, the surgeon performs a vitrectomy, then uses fine forceps to gently lift and peel the membrane, sometimes also removing the inner limiting membrane. A dye may be used to highlight the tissue.
- Usually done under local anaesthetic with sedation or general anaesthetic
- Most cases do not require a long-acting gas tamponade
- Cataract surgery may be combined or needed later
- Risks include retinal tear, detachment, or infection, though these are uncommon
Visual Results
Many patients notice gradual improvement in distortion and clarity over months, though full normal vision is not always achievable. Earlier surgery before severe macular damage tends to yield better outcomes.
- Post-operative drops reduce inflammation and infection risk
- Metamorphopsia may persist but often lessens over time
- Regular monitoring checks for complications or recurrence
- Low-vision aids can support reading while recovery progresses
