Dragged Fovea Diplopia Syndrome after Epiretinal Membrane Peel Surgery

Background: Dragged fovea diplopia syndrome is a condition involving intractable binocular diplopia associated with macular pathology often involving epiretinal membrane and macular pucker. The prevalence of this condition is unknown. There is no known cure for this condition but effective treatment for the symptoms is available. Case Reports: Two cases of intractable central binocular diplopia of 2 to 3 years duration that were not correctable with prism are presented. Both patients had a history of epiretinal membrane and had undergone membrane peel with vitrectomy. No extraocular muscle dysfunction or paresis were evident in either patient. Both responded favorably to partial monocular occlusion with semitransparent tape. Conclusion: Dragged fovea diplopia can be extremely frustrating for both patients and doctors. An understanding of this condition will allow practitioners to detect it and treat the symptoms to allow patients to function normally.
