Epiretinal Membrane (ERM)
This photo shows an highly magnified view of the retina. In it, I am removing the epiretinal membrane that is dyed blue. I use microscopic forceps to gently peel the scar tissue off the retina.
What is an Epiretinal Membrane?
An Epiretinal Membrane (or ERM) is a thin layer of scar tissue that forms on the macula. This is the part of the retina that we use to read and see fine detail in the distance.
It is usually caused by natural ageing processes inside the eye. However, it is sometimes caused by conditions such as diabetes, blockages in blood vessels, inflammation and trauma.
What are the symptoms of an epiretinal membrane?
In some people, epiretinal membranes may cause distorted or blurred vision that can affect tasks that require good central vision such as reading or driving.
How do you treat an epiretinal membrane?
Most epiretinal membranes do not require treatment. If your quality of life is affected, surgery can improve your symptoms.
What does the treatment involve?
Surgery for epiretinal membranes is usually done as a day case under local anaesthesia. The operation lasts less than 60 minutes and involves a procedure known as vitrectomy, where microscopic instruments are introduced through the white of the eye to allow the membrane to be gently peeled off the surface of the retina. This can be combined with cataract surgery at the same time if required.
Where will I have my surgery?
I operate Bristol’s leading private eye clinic, Vision Care Clinic based at the Nuffield Health Bristol Hospital.
