Background: "Dragged-fovea diplopia syndrome" is a type of central binocular diplopia that is secondary to a foveal displacement, caused by epiretinal membranes (ERMs) or other macular diseases. Its management is difficult, because prisms are not effective.
Case Reports: Two cases of dragged-fovea diplopia syndrome were presented. Both patients were affected with a unilateral epiretinal membrane. Therefore, the pathophysiology underlying their diplopia was the conflict between central and peripheral fusion mechanisms.
Conclusions: Diplopia caused by ERM "shift" deserves a complex management. We suggest to be careful about subjective symptoms and to optimize the residual visual function to customize the orthoptic management. A strict cooperation between ophthalmologists and orthoptists could lead to a successful outcome.
