Epiretinal membrane refers to the thin fibrous tissue layer, covering the retina surface. Epiretinal membrane can cause retina wrinkling. This often occurs after age 50.
Because of aging, the vitreous gradually shrinks, the immune system may response to protect the retina - this may cause the fibrous membrane to grow. This tend to make the retina wrinkling, causing blurred or distorted vision. The following disease may also cause retina wrinkling: uveitis, diabetic retinopathy, retinal detachment, eye injury.
Epiretinal membrane may also cause vascular leakage or retinal edema. If the situation is severe, or vision is poor, the membrane-peeling surgery can be used to remove the fibrous membrane.
