title: Long-Term Outcomes of Three Cases That Underwent a Muscle Transposition Procedure Without Tenotomy Caused by Abducens Palsy.
abstract: Few reports have discussed long-term outcomes of muscle transposition procedures. In this study, cases with abducens palsy treated with a muscle transposition procedure were followed for 12, 25, or 26 years. The preoperative alignments were esotropia of 65 degrees, 47 prism dioptres (PD), and 24 PD, respectively. Orthophoria was postoperatively achieved in all cases. The postoperative alignment in one case deteriorated at 8 years postoperatively, although orthophoria were maintained in the other two cases. These findings indicate that it is possible that esotropia can recur even though orthophoria was maintained for several years postoperatively in some cases that underwent a muscle transposition procedure.
