Récidive d'une membrane épirétinienne idiopathique dite « vasocentrique » : particularités cliniques et chirurgicales

The vasocentric epiretinal membranes (ERM) are idiopathic ERM centered on retinal blood vessels, described mainly in young patients. We report a case of a 70-year-old patient who presented with a decrease in visual acuity secondary to a vasocentric epiretinal membrane. A successful vitrectomy and ERM removal were performed. Four years after surgery, a contractile ERM centered on the superior temporal blood vessel occurred and was associated with retinal distortions at the posterior pole. The second surgery combined removal of the recurrent ERM, which was adherent to the temporal vessels, and peeling of the internal limiting membrane in the macular area. Although there was visual recovery, the patient is still suffering from metamorphopsia 2 years after surgery. The vasocentric ERM have a poor visual outcome and a high risk of recurrence in comparison with other ERM disorders. This case report describes the main clinical and surgical characteristics of this type of membrane.
