The epimacular membrane (EMM) is a degenerative condition associated with age, with a variable impact on vision. Treatment is surgery based and consists of a vitrectomy followed by a peeling of the epimacular membrane using a microgripper. Peeling of the internal limiting membrane (ILM) is an adjuvant action that is now frequently practiced and which is expected to increase the success rate of EMM surgery by reducing the risk of recurrence of EMM. Although ILM peeling does not seem to have an adverse effect on visual acuity, it is not totally without consequence, it involves the risk of histological disorganization of the retina at the origin of one or several microscotomas, which are themselves responsible for a final visual discomfort. These microscotomas, resulting in the perception of somewhat black spots visible near the fixed point or the fixed image, may be highlighted by microperimetry and would be a loss of functional opportunity for the patient.
