A 69-year-old man developed binocular, vertical diplopia after undergoing ca taract extraction in both eyes. He had normal extraocular motility and a 2 prism diopter right hypertropia that was comitant but could not be relieved with over lying prisms. Funduscopy revealed an epiretinal membrane within the macula on th e left more than the right. After his metamorphopsia worsened, and his visual ac uity decreased to 20/40 in the left eye, he underwent pars plana vitrectomy with removal of the epiretinal membrane and his diplopia resolved. Macular pathology including epiretinal membranes and choroidal neovascular membranes may rarely c ause binocular diplopia because of foveal displacement and rivalry between centr al and peripheral fusional mechanisms.
