Causes of Diplopia in Patients With Epiretinal Membranes

Patients with ERM and presenting diplopia may have 1 of several causes of diplopia, most commonly retinal misregistration (central-peripheral rivalry-type diplopia). Nevertheless, diplopic patients with retinal misregistration may also have treatable strabismus or optical/refractive error as the primary barrier to single vision and therefore many potential barriers to single vision should be considered.
