The aim of this study is to evaluate whether the pre-operative integrity or not of the inner segment (IS) and outer segment (OS) photoreceptoral junction may influence the post-operative visual acuity, the macular morphology (assessed by Spectral Domain-Optical Coherence Tomography (SD-OCT)) and function (evaluated by Multifocal Electroretinogram -mfERG) in patients with idiopathic epimacular membrane (EMM) followed-up for 6-month. In this observational prospective study, EMM patients are enrolled. They are divided into 2 groups in relationship to the pre-operative integrity of the SD-OCT IS/OS junction: the group with an intact IS/OS junction (EMM-I Group) and the group with a disrupted IS/OS junction (EMM-D Group). For each enrolled patient, visual acuity (VA), mfERG and SD-OCT were assessed at baseline (pre-operative) and after 1, 3 and 6 months of follow-up after surgical treatment for EMM (pars plana vitrectomy with EMM removal and internal limiting membrane peeling).
