Despite the most careful retinal detachment surgery saving the eye muscles and the fascial structures, an extraocular muscle imbalance may occur. This can be expected especially when for scleral buckling procedures large implants or exoplants were used, or had to be placed under a rectus muscle. In some cases, however, postoperative diplopia results from decompensation of preexisting heterophoria or congenital ocular motor imbalance. A clear-cut differential diagnosis to separate these entities is essential for therapeutic considerations.
